Answer:
Step-by-step explanation:
To put a quadratic into vertex form, you need to complete the square on it. Do this by following these steps. I'll tell you what we're doing and then show you what it looks like.
First step is to set the quadratic equal to 0 and then move the constant over. That's 2 steps in one, but not confusing at all. That looks like this:
[tex]2x^2-16x=-30[/tex]
Next, the rule is that the leading coefficient has to be a positive 1. Ours is a 2, so we will factor out a 2 but only from the left side. That looks like this:
[tex]2(x^2-8x)=-30[/tex]
Next step is to take half the linear term (the number with the x attached to it, not the x-squared), square it, and add it in to both sides. This is where things get a bit tricky, so pay attention. Our linear term is 8, half of 8 is 4, and 4 squared is 16. So we add 16 in. We'll do it to the left only first:
[tex]2(x^2-8x+16)[/tex]
That's the left side. Notice that there is still a 2 out front there. That 2 is a multiplier. That means that what we actually added in was 2(16) = 32, not just 16. Now adding that to the right makes the whole thing:
[tex]2(x^2-8x+16)=-30+32[/tex]
Completing the square allows us to create a perfect square binomial on the left which is in the form (x - )². That blank space is filled in with the number we squared and then added in. We squared a 4 to get 16, so our perfect square binomial is (x - 4)². Putting that together:
[tex]2(x-4)^2=2[/tex]
Last step is to move the constant back over and set the quadratic back equal to y:
[tex]y=2(x-4)^2-2[/tex]
From here the vertex is apparent. It is (4, -2).

Step-by-step explanation:
Step 1: Rewrite 1st equation
-b = -5 - 6a
b = 5 + 6a
Step 2: Substitution
4a - 3(5 + 6a) = -8
Step 3: Solve
4a - 15 - 18a = -8
-14a - 15 = -8
-14a = 7
a = -1/2
Step 4: Plug in a to find b

Find the slope of the line that passes through (–7, 1) and (7, 8)
Answer:
slope= 1/2x
Step-by-step explanation:
For this line, you can count it going up 7 and to the right 14. Next, to calculate the slope, you take the change in y over the change in x, and you take those numbers (7 and 14) and divide 7 by 14 to get the slope, which simplifies to 1/2x, the slope.
Answer:
1/2
Step-by-step explanation:
The slope formula is:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
where (x1,y1) and (x1, y2) are 2 points the line passes through.
We are given the points:
(-7,1) and (7,8). Match the corresponding variables with the points.
x1= -7
y1= 1
x2= 7
y2= 8
Substitute these values into the formula.
[tex]m=\frac{8-1 }{7--7 }[/tex]
Solve the numerator first. Subtract 1 from 8.
[tex]m=\frac{7 }{7--7 }[/tex]
Now solve the denominator. Subtract -7 from 7, or add 7 and 7.
[tex]m=\frac{7}{7+7}[/tex]
[tex]m=\frac{7}{14}[/tex]
This fraction can be simplified. Both 7 and 14 can be divided evenly by 7.
[tex]m= \frac{(7/7)}{(14/7)}[/tex]
[tex]m=\frac{1}{2}[/tex]
The slope of the line is 1/2.
Derive the equation of the parabola with a focus at (6, 2) and a directrix of y = 1. f(x) = −one half(x − 6)2 + three halves f(x) = one half(x − 6)2 + three halves f(x) = −one half(x + three halves)2 + 6 f(x) = one half(x + three halves)2 + 6
Answer:
Second choice.
f(x) = 1/2(x - 6)^2 + 3/2.
Step-by-step explanation:
The distance of a point (x, y) from the focus = the distance of the point from the directrix, so:
(x - 6)^2 + (y - 2)^2 = (y - 1)^2
x^2 - 12x + 36 + y^2 - 4y + 4 = y^2 - 2y + 1
x^2 -12x + 39 = 2y
y = f(x) = 1/2 (x^2 - 12x + 39)
I see you want the answer in vertex for so it is:
f(x) = 1/2 [ (x - 6)^2 - 36) + 39)
f(x) = 1/2(x - 6)^2 + 3)
f(x) = 1/2(x - 6)^2 + 3/2.
A parabola is a plane that is approximately U-shaped.
The equation of the parabola is: [tex]\mathbf{y = \frac{1}{2}(x - 6)^2 + \frac 32}[/tex]
The given parameters are:
[tex]\mathbf{Focus = (6,2)}[/tex]
[tex]\mathbf{Directrix: y = 1}[/tex]
First, equate the directrix to 0
[tex]\mathbf{y - 1 = 0}[/tex]
The equation is then calculated as:
[tex]\mathbf{(x - a)^2 + (y - b)^2 = (y- 1)^2}[/tex]
Where:
[tex]\mathbf{(a,b) = (6,2)}[/tex]
So, we have:
[tex]\mathbf{(x - 6)^2 + (y - 2)^2 = (y- 1)^2}[/tex]
Expand
[tex]\mathbf{x^2 - 12x +36 + y^2 - 4y + 4 = y^2 - 2y + 1}[/tex]
Subtract y^2 from both sides
[tex]\mathbf{x^2 - 12x +36 - 4y + 4 =- 2y + 1}[/tex]
Collect like terms
[tex]\mathbf{x^2 - 12x +36 + 4 - 1 =4y - 2y}[/tex]
[tex]\mathbf{x^2 - 12x +39 =2y}[/tex]
Divide through by 2
[tex]\mathbf{y = \frac{1}{2}(x^2 - 12x +39)}[/tex]
Express 39 as 36 + 3
[tex]\mathbf{y = \frac{1}{2}(x^2 - 12x +36 + 3)}[/tex]
Factor out 3/2
[tex]\mathbf{y = \frac{1}{2}(x^2 - 12x +36) + \frac 32}[/tex]
Expand the bracket
[tex]\mathbf{y = \frac{1}{2}(x^2 - 6x - 6x +36) + \frac 32}[/tex]
Factorize
[tex]\mathbf{y = \frac{1}{2}(x(x - 6) - 6(x -6)) + \frac 32}[/tex]
Factor out x - 6
[tex]\mathbf{y = \frac{1}{2}((x - 6) (x -6)) + \frac 32}[/tex]
Express as squares
[tex]\mathbf{y = \frac{1}{2}(x - 6)^2 + \frac 32}[/tex]
Hence, the equation of the parabola is: [tex]\mathbf{y = \frac{1}{2}(x - 6)^2 + \frac 32}[/tex]

The triangular prism has a volume of 27 cubic units. A triangular prism. What will be the volume of the prism if each side is dilated by a factor One-third? 1 cubic unit 3 cubic units 8 cubic units 9 cubic units
Answer:
Option (2)
Step-by-step explanation:
Volume of a prism A (preimage) = 27 cubic units
Factor of dilation of the sides of this prism (image) = [tex]\frac{1}{3}[/tex]
Volume scale factor of these prisms = [tex]\frac{\text{Volume of image}}{\text{Volume of preimage}}[/tex]
Since, Volume scale factor = (Scale factor of dilation of the sides)³
= [tex](\frac{1}{3})^3[/tex]
= [tex]\frac{1}{9}[/tex]
Now from the formula of volume scale factor,
[tex]\frac{1}{9}=\frac{\text{Volume of image}}{\text{Volume of preimage}}[/tex]
[tex]\frac{1}{9}=\frac{\text{Volume of image}}{27}[/tex]
Volume of the image prism = [tex]\frac{27}{9}[/tex] = 3 cubic units
Therefore, Option (2) will be the answer.

A zoo has a menagerie containing four pairs of different animals, one male and one female for each. The zookeeper wishes to feed the animals in a specific pattern: each time he feeds a single animal, the next one he feeds must be a different gender. If he starts by feeding the male giraffe, how many ways can he feed all the animals?
Answer:
144
Step-by-step explanation:
We will use permutations to solve this problem
There are 4 pairs each having a male and a female.
The total number of sample points is 4! = 4*3*2*1= 24
He chooses the male first then the number of sample space he is left with are 3! = 3*2*1=6
The total number of ways he can select is 4! 3! = 24 * 6= 144
Another way of finding it out is
he has 4 pairs each having a male and a female so he chooses 1st male then he would choose from this
4 female choices*3 male choices * 3 female choices *2 male choices *2 female choices *1 male choices *1 female choices *= 4*3*3*2*2*1*1= 144
The zookeeper can feed all the animals in 144 ways
The number of different animals is given as:
[tex]n = 4[/tex]
The number of ways to feed any of the 4 male animals is:
[tex]Ways = 4![/tex]
Expand
[tex]Ways = 4 \times 3 \times 2 \times 1[/tex]
[tex]Ways = 24[/tex]
From the question, we understand that the female of the particular animal cannot be selected (yet).
So, there are 3 female animals left.
The number of ways to feed any of the 3 female animals is:
[tex]Ways = 3![/tex]
Expand
[tex]Ways = 3 \times 2 \times 1[/tex]
[tex]Ways = 6[/tex]
So, the number (n) of ways to feed all the animals is:
[tex]n = 24 \times 6[/tex]
[tex]n = 144[/tex]
Hence, he can feed all the animals in 144 ways

if C is the midpoint of EF, C has coordinate -8, F has coordinate 4, then find the coordinate of E
==========================================================
Work Shown:
Let x be the location of E on the number line.
Since C is the midpoint of E and F, this means we can find C's location by adding E and F together and dividing that sum by 2
midpoint = (endpoint1 + endpoint2)/2
C = (E+F)/2
Plug in E = x, C = -8 and F = 4. Then solve for x
C = (E+F)/2
-8 = (x+4)/2
(x+4)/2 = -8
x+4 = 2(-8) .... multiplying both sides by 2
x+4 = -16
x = -16-4 .... subtract 4 from both sides
x = -20
The location of point E on the number line is -20
-------------
As a check, lets add E and F to get E+F = -20+4 = -16
Then cut this in half to get -16/2 = -8, which is the proper location of point C
This confirms our answer.

Find the measure of the unknown acute angle. Round your answer to the nearest degree.
Answer:
d. x° = 27°, y° = 63°
Step-by-step explanation:
To choose the correct answer, you only need to know that the smaller angle is opposite the shorter side. x° is opposite the shorter side so will have a smaller measure than y°.
The correct choice is ...
d. x° = 27°, y° = 63°
_____
If you want to actually go to the trouble to determine the angles exactly, you can use the tangent relation:
Tan = Opposite/Adjacent
tan(x°) = 4/8
x° = arctan(1/2) ≈ 26.56°
x° ≈ 27°
y can be computed as the complement of this, or can be computed in similar fashion:
tan(y°) = 8/4
y° = arctan(2) ≈ 63.43°
y° ≈ 63°
Grey’s Labs is testing a new growth inhibitor for a certain type of bacteria. The bacteria naturally grows exponentially at a rate of 4.7% each hour. The lab technicians know that the growth inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. The current sample contains 90 bacteria. Once a standard tube contains more than 270 bacteria, the sample will stop growing. So, to analyze the effect of the inhibitor over longer spans of time, the lab technicians move the bacteria to larger containers, essentially increasing the container size at a constant rate. This adaptation accommodates 100 more bacteria each hour. The research team wants to track the number of bacteria over time given these two conditions. Select the two inequalities they can use to model this situation.
P ≥ 90e^(0.047t)
P ≤ 270 + 100t
P ≤ 270 – 100t
P ≤ 0.047e^(90t)
P ≤ 90e^(0.047t)
Answer:
The two inequalities are;
P ≤ 90e^(0.047t)
P ≤ 270 + 100·t
Step-by-step explanation:
The parameters given for the testing of the new growth inhibitor are;
The growth rate of the bacteria = 4.7% exponentially
The growth inhibitor lowers the growth rate
The population of bacteria after time, t = P
The increase in the number of bacteria per unit time in the 100
The maximum number of bacteria in the standard tube = 270
Therefore, the number of bacteria after the first filling of the tube is P ≤ 270 + 100·t
The equation for exponential growth is [tex]A_0 e^{kt}[/tex]
Where:
A₀ = Initial population = 90
k = Percentage growth rate as percentage
t = Time
The equation for the population of bacteria under the influence of the inhibitor is therefore;
P ≤ [tex]90 \times e^{0.047 \cdot t}[/tex] which is P ≤ 90e^(0.047t).
Answer:
P≤270+100t

[tex]\boxed{BC = 11.62}[/tex]
Step-by-step explanation:
Tan 54 = [tex]\frac{opposite}{adjacent}[/tex]
Where opposite = 16, Adjacent = BC
1.376 = [tex]\frac{16}{BC}[/tex]
BC = 16/1.376
BC = 11.62
Answer:
11.62468045 or 11.6 to 1 decimal place
Step-by-step explanation:
→ We need to utilise trigonometry. The first step would be to list out the formula triangles
Tan = Opposite ÷ Adjacent
Sin = Opposite ÷ Hypotenuse
Cos = Adjacent ÷ Hypotenuse
→ Now we need to know which triangle to use, we do that by identifying the side or length we are not given in the triangle and then finding a formula without the name of the given side. First let's identify all the sides.
Opposite = AC = 16
Adjacent = BC = We need to find this out
Hypotenuse = AB = No given value
→ Now we look for a formula with hypotenuse
Tan = Opposite ÷ Adjacent
→ The (Tan = Opposite ÷ Adjacent) is the formula we are going to be using. Since we want to find out the adjacent, we have to rearrange to get adjacent as the subject
Adjacent = Opposite ÷ Tan
→ Now we identify the Opposite and the Tan
Opposite = 16
Tan = 54°
Side note ⇒ Sin, cos and tan will always be the angles
→ Substitute in the values in the formula
Adjacent = Opposite ÷ Tan ⇔ Adjacent = 16 ÷ Tan (54) ⇔ Adjacent = 11.6
→ The adjacent is 11.6 to 1 decimal place
1)How many pinches of salt would be in 24 servings?
2) How many eggs would be needed to serve 18 people?
3) If you only had 33g of flour, how much of the other
ingredients would you need?
4) If 2 eggs were used, how many grams of flour would be
needed?
5) How much flour would be needed if 900ml milk is used?
HELP!!
Answer:
1. 2 pinch of salt
2. 3/2 egg =1.5 eggs
3. 33g of flour=1/3 pinch of salt
33g of flour=1/3 tbsp of oil
33g of flour=1/3 egg
33g of flour=100ml of milk
4. 24 servings
5. 300g of flour
Step-by-step explanation:
12 servings
Plain flour=100g
Salt=a pinch
Oil= 1 tbsp
Egg=1
Milk=300 ml
1. Pinches of salt in 24 servings
24
12 servings=1 pinch of salt
24 servings=24/12*1 pinch of salt
=2*1 pinch of salt
=2 pinch of salt
2. Egg needed for 18 servings
12 servings=1 egg
18 servings=18/12 * 1 egg
=3/2* 1 egg
=3/2 egg
3. If there are 33 grams of flour,
The other ingredients will be
33g/100g=1/3
The other ingredients will be 1/3 of the original measurement
Salt=a pinch
33g of flour=1/3 pinch of salt
Oil= 1 tbsp
33g of flour=1/3 tbsp of oil
Egg=1
33g of flour=1/3 egg
Milk=300 ml
33g of flour=1/3 of 300ml
=1/3*300
=300/3
=100ml of milk
4. If two eggs were used, grams of flour needed is
1 egg =12 servings
2 eggs=2* 12 servings
=24 servings
5. Flour needed if 900ml milk is used
100g flour=300ml of milk
900ml of milk=300ml * 3
Therefore,
900ml of milk=100g of flour *3
900ml of milk=300g of flour

Answer:
The answer is 13
Step-by-step explanation:
You'll say what will you multiply by itself to give you 169.
It will be 13 times itself and it will be =169.
