Step-by-step explanation:
Name the true solution(s) to the equation. name the extraneous solution(s) to the equation.
The true solution to the equation [tex]\(x + 5 - \sqrt{x} = 3\)[/tex] is [tex]\(x = \frac{4}{9}\)[/tex], and there are no extraneous solutions.
To find the true solution(s) to the equation, we need to solve for x and check if the obtained solutions satisfy the original equation. The extraneous solution(s), if any, will be the solutions that do not satisfy the original equation.
To solve the equation, we can start by isolating one of the square root terms. Rearranging the equation, we have:
[tex]\sqrt{x + 5} = 3 + \sqrt{x}[/tex].
The equation can be evaluated as:
[tex]\sqrt{x + 5} - \sqrt{x} &= 3 \\(\sqrt{x + 5})^2 &= (3 + \sqrt{x})^2 \\x + 5 &= 9 + 6\sqrt{x} + x \\6\sqrt{x} &= -4 \\\sqrt{x} &= \frac{-2}{3} \\x &= \frac{4}{9}\end{align*}[/tex]
Therefore, the true solution to the equation [tex]\(x + 5 - \sqrt{x} = 3\)[/tex] is [tex]\(x = \frac{4}{9}\)[/tex], and there are no extraneous solutions.

In ΔRST, r = 79 inches, t = 70 inches and ∠T=58°. Find all possible values of ∠R, to the nearest 10th of a degree
In ΔRST, the measure of angle R is 73.1°
Let us assume that r represents the opposite side of ∠R, and 't' represents the opposite side of ∠T
i.e., r = side ST and t = side RS
We know that the law of sine for triangle states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.
i.e., for triangle ABC,
[tex]\frac{sin~A}{a} =\frac{sin~B}{b} =\frac{sin~C}{c}[/tex]
Using sine law for ΔRST,
[tex]\frac{sin~R}{r} = \frac{sin~S}{s} =\frac{sin~T}{t}[/tex]
Consider equation,
[tex]\frac{sin~R}{r} =\frac{sin~T}{t} \\\\\frac{sin~R}{79} = \frac{sin~(58)}{70}[/tex]
79 × 0.8481 = sin(R) × 70
sin(R) = 66.99 / 70
sin(R) = 0.9571
∠R = arcsin(0.9571)
∠R = 73.1°

Yes, it is worth the extra drive to going the far store for buying the chicken. The difference between the both store worth is about $1.24.
We have to buy some chicken for dinner tonight. We found an ad showing that the store across town has it on sale for $3.09 a pound, which is cheaper than our usual neighborhood store, which sells it for $3.19 a pound.
Let's compare chicken costs: We need 3 pounds of chicken so, we would pay$3.09 ×3 = $19.14 (far store)
$3.19 × 3 = $20.34 (near store)
Let's see at how much it costs to travel in our car:For the neighbourhood store :
Distance = 2.3 mile
Multiply by 2 because we not only have to drive there, but also back home for the round trip: so, total distance = 2.3 miles × 2 = 4.6 miles
As car average is 19 miles per gallon
= 4.6 mile/ 19 miles per gallon
= 0.24 gallon < 13 gallons
Now, costs to travel to each store from the gas used. Cost of gas is $3.62/gallon,
total cost = 0.2421 gallons×$3.62 /gallons = $0.88
Similarly for far store : distance from home to store = 8.7 miles but take double of it we get, 8.7 miles × 2 = 17.4 miles
As car average is 19 miles per gallon
= 17.4 miles /19 miles per gallons
= 0.915 gallons < 13 gallons
The cost of gas for the respective trip = 0.915 gallons × $3.62 /gallons = $3.32
Now, let's add the gas and chicken costs together to get total worth
$19.14 + $3.32 = $22.46 to the far store
$20.34+ $0.88 = $21.22 to the near store
Hence, the worth in travelling far store is greater than neighbourhoid store.

You found an ad showing that the store across town has it on sale for $3.09 a pound, which is cheaper than your usual neighborhood store, which sells it for $3.19 a pound. Is it worth the extra drive? First, determine what information you need to answer this question, then click here to display that info (along with other info).
How much chicken will you be buying? 3 pounds
How far apart are the two stores? My neighborhood store is 2.3 miles away, and takes about 8 minutes. The store across town is 8.7 miles away, and takes about 25 minutes.
How kind of mileage does your car get? It averages about 19 miles per gallon in the city.
How many gallons does your car hold? About 13 gallons
How much is gas? About $3.62/gallon right now.
Yes, it is worth the extra drive to the far store to get the chicken. The value of the two stores varied by around $1.24.
To make chicken for dinner tonight, we must purchase some. We discovered an advertisement indicating that the supermarket across town is selling it for $3.09 per pound, which is less expensive than our typical neighborhood grocery, which charges $3.19 per pound.
Compare the prices of chicken: We would pay for the 3 pounds of chicken that we require.
$3.09 ×3 = $19.14 (far store)
$3.19 × 3 = $20.34 (near store)
Let's look at the expense of driving in our car:
For the local retailer: = 2.3 miles away
Because we need to travel both ways, we must double the distance by two, making the total distance 2.3 miles x 2 = 4.6 miles.
Since the average automobile gets 19 mpg
19 miles per gallon/4.6 miles = 13 gallons x 0.24 gallons
Now, add the cost of gas used to drive to each store. Gas costs $3.62 per gallon.
Total cost = 0.2421 gallons at a cost of $0.88 per gallon.
The same goes for a far store:
the distance from home to the store is 8.7 miles, but if we double that by two, we get 17.4 miles.
Since the average automobile gets 19 mpg = 17.4 miles per gallon /19 miles per mile
13 gallons equals 0.915 gallons.
The gas price for the relevant journey is 0.915 gallons times $3.62 a gallon, or $3.32.
To determine the overall cost,
let's now combine the costs of the chicken and petrol.
$22.46 to the far store from $19.14 plus $3.32
$20.34 plus $0.88 equals $21.22 for the nearby retailer.
Therefore, a far store is more valuable than a nearby store. The difference is $1.24

Give difference between sides and diagonal of square?A square is a two-dimensional, regular geometric shape with four sides of equal length and four angles of 90 degrees. The sides of a square are the four straight lines that make up the shape. The length of each side is the same as the length of the other three sides.The diagonal of a square is a line segment that connects two opposite corners of the square. The diagonal is not a side of the square, as it does not run along the same line as the other sides. The diagonal of a square is always the same length, which is the square root of the sum of the squares of the sides. This is known as the Pythagorean Theorem.The sides of a square are all equal, while the diagonal of a square is not equal to any of the sides. The length of the sides of a square is always the same, regardless of the size of the square, while the length of the diagonal of a square varies with the size of the square. The diagonal of a square is always longer than any of the sides, since it is the hypotenuse of a right triangle.Solution:
8. We can solve this problem by using the Pythagorean Theorem. We know that the sides of a square are equal, so we can set up an equation using the theorem. VC = 6z, VR = 12, and we want the hypotenuse, VRHK, to be a square. VH² = VR² + RH² = 12√2.
VC = 6z = VH/2 = 12√2/2 = 6√2

What blood types can someone with type A blood donate to? (select all that
apply)
Blood types A and AB are receivers from someone with type A blood donors.
What is blood type?
There are four major blood groups determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (–), creating the 8 most common blood types (A+, A-, B+, B-, O+, O-, AB+, AB-).
Someone with blood type A can donate blood to individuals with blood types A and AB.
This is because type A blood has the A antigen on the red blood cells and type AB has both A and B antigens.
While type A blood doesn't have the B antigen which is present in type B and AB blood, so it cannot be donated to those with type B or type B.
It's important to note that there are also positive and negative blood types, which are determined by the presence or absence of the Rh (Rhesus) antigen on the red blood cells.
So, someone with type A negative blood can only donate to individuals with type A negative or type AB negative blood.

A colony of 100 bacteria doubles in size every 60 hours what will the population be 189 hours from now
By evaluating an exponential equation, we will see that the population after 189 hours will be 888 bacteria.
What will be the population in 189 hours from now?We know that initially we have a total of 100 bacteria, and it doubles in size every 60 hours, then the population can be modeled with the exponential equation.
p(x) = 100*(2)^x
Where x is groups of 60 hours, we can rewrite:
x = t/60h
Where t is the amount of hours, and rewrite the equation as:
p(t) = 100*(2)^(t/60h)
The population in 189 hours from now willbe:
p(189 h) = 100*(2)^(198 h/60h) = 887.7
The population is 888 (where we rounded the value)

BRO MY MATH TEACHER IS ON TO ME SOMEONE HELP A family camping in a national forest builds a temporary shelter with a tarp and a 6-foot pole. The bottom of the pole is even with the ground, and one corner is staked 10 feet from the bottom of the pole. What is the slope of the tarp from that corner to the top of the pole?
To find the slope of the tarp, we can use the concept of rise over run, which is the ratio of the vertical change (the rise) to the horizontal change (the run). In this case, the rise is the distance from the corner of the tarp to the top of the pole, and the run is the distance from the corner of the tarp to the bottom of the pole.
We can use the Pythagorean theorem to find the length of the hypotenuse of the right-angled triangle formed by the corner of the tarp, the bottom of the pole and the top of the pole.
The length of the hypotenuse is the distance from the corner of the tarp to the top of the pole and the length of the adjacent side is the distance from the corner of the tarp to the bottom of the pole.
We know that:
adjacent side = 10 ft
Hypotenuse = h
Applying the Pythagorean theorem:
h^2 = 10^2 + 6^2
h = √(10^2 + 6^2)
h = √(100 + 36) = √136 = 11.66 ft
Now we can calculate the slope:
slope = rise/run = (h-10) / 6
slope = (11.66-10) / 6 = 1.66/6 = 0.277
So the slope of the tarp from the corner to the top of the pole is 0.277 or approximately 0.28.

4. In parallelogram EFGH, what is the relationship between angle e and angle g?
e° – g° = 180°
e° = -g°
e° = g°
e° + g° = 180°
1. In parallelogram ABCD, the sum of ∠a and ∠b is 180 degree. So the option d "a° + b° = 180°" is correct.
2. In rectangle FGHK, FC = CH = 8. 5 cm, then the area of rectangle FGHK is 120 square cm. So the option b is correct.
3. The length of GK is 17 cm because the length of all diagonal is same in rectangle. So the option d is correct.
4. In parallelogram EFGH, the sum of ∠e and ∠f is 180 degree. So the option d "a° + b° = 180°" is correct.
1. In parallelogram ABCD, ∠a and ∠b are adjacent to each other.
So, AB║DC.
Then we get ∠a and ∠b as subsequent interior angles, both of which need to be added.
So the sum of ∠a and ∠b is 180 degree.
a° + b° = 180°
2. In rectangle FGHK, FC = CH = 8. 5 cm.
From the diagram, FG = 8 cm
FH = FC + CH
FH = 8.5 + 8.5
FH = 17 cm
Using Pythagorean Theorem to find the value of GH.
FH^2 = FG^2 + GH^2
(17)^2 = (8)^2 + GH^2
289 = 64 + GH^2
Subtract 64 on both side, we get
GH^2 = 225
Taking square root on both side, we get
GH = 15 cm
The area of rectangle = FG × GH
The area of rectangle = 8 × 15
The area of rectangle = 120 square cm
3. In rectangle FGHK, FC = CH = 8. 5 cm.
So FH = FC + CH
FH = 8.5 + 8.5
FH = 17 cm
As, a rectangle is split into two congruent right triangles by a diagonal. The length of the rectangle's diagonals are all the same.
So GK = FH = 17 cm
4. In parallelogram EFGH, ∠e and ∠f are adjacent to each other.
So, EF║HG.
Then we get ∠e and ∠f as subsequent interior angles, both of which need to be added.
So the sum of ∠e and ∠f is 180 degree.
e° + f° = 180°

there were x quarts of liquid in a con-tainer. first, 3 4 of the liquid in the container was removed. then another 1 2 quart was poured into the container. write an expression in terms of x for the number of quarts of liquid in the container at the end. then write another equivalent expres-sion.explain
The another equivalent expression of total liquid is (x+2)/4.
Expressions that perform similarly but differ in appearance are said to be equivalent expressions. When the same value for the variable is entered, two algebraic expressions that are equivalent will have the same result.
x quarts liquid in the container 3/4 part of liquid is removed
Then remaining liquid in container = X - [tex]\frac{3}{4}X[/tex]
Then remaining liquid in container = x/4quarts
Another 1/2 quart is poured into container
Then total liquid = [tex]X-\frac{3}{4}X+\frac{1}{2}[/tex] quarts
total liquid = [tex]\frac{X+2}{4}[/tex] quarts
So, then the another equivalent expression of total liquid is (x+2)/4.

Write an expression that only uses multiplication and that is equivalent to x reduced by 1/8 of x
The expression that only uses multiplication and that is equivalent to x reduced by 1/8 of x is: x * (1 - 1/8).
An expression in mathematics is a combination of numbers, variables, and operations that represent a value or set of values.
The expression calculates the reduction of x by 1/8 of x by subtracting 1/8 of x from x, which is x * 1/8. By subtracting this from x, the expression calculates x reduced by 1/8 of x. The expression that only uses multiplication and that is equivalent to x reduced by 1/8 of x is:

a six foot man standing 200 feet from a tower observes the angle of elevation to the top of the tower to be 67 degrees. how high is the tower?
So, the height of the tower is approximately 363.6 feet.
You can use trigonometry to solve this problem.
If we call the height of the tower "h" and the distance between the man and the base of the tower "d", then the angle of elevation is defined as the angle between the line of sight from the observer to the top of the tower and the horizontal line.
We can use the tangent function to relate the angle of elevation to the height and distance.
tan(67) = h/d
We know that the distance between the man and the tower is 200 feet. We can use this information to find the height of the tower.
h = d * tan(67)
h = 200 * tan(67)
The height of the tower is approximately 363.6 feet.
Please note that due to the approximation of the trigonometric functions, the answer may not be exactly as calculated.

Find the missing variables in the triangle below. Leave your answer in simplest radical form.
the value of x, y, and z are 2√14, √74, and √252.
What is the right-angle triangle?A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.
Given, the right triangle that has two other right triangles inside it:
From the Pythagorean theorem:
Hyppotaneus ² = height ² + base²
from the Bigger triangle:
H = 14 + 4 = 18
b = y
h = x
Thus,
y² + z² = 18*18
y² + z² = 324.....(1)
from the triangle with a height of 14,
z² = x² + 14²
z² = x² + 196....(2)
From the triangle with the base of 4:
y² = x² + 16...(3)
For equations 2 and 3 substitute the value in equation 1
2x² + 212 = 324
2x² = 112
x² = 56; x = 2√14
Thus,
y² = 56 +16
y² = 74; y = √74
z² = 56 + 196
z² = 252; z = √252
Therefore, the value of x, y, and z are 2√14, √74, and √252.
