The net below represents a container. What solid figure does it show.
Answer:
Looks like a cuboid
Hope it helps :)
Have a great day!
The net below represents a container. What solid figure does it show?
____________________Solution :-We can see that the given net has 12 edges, 6 faces and 8 vertices if we compile it up. These number of edges, faces and vertices are found in a cuboid or a rectangular prism. With this we can conclude that if we compile the given net, it will form a cuboid or a rectangular prism. So, the given net is of a cuboid or a rectangular prism.
____________________Final Answer :-The given net is of a cuboid or a rectangular prism.
____________________y=-2x-5
y=5x+6
Round to the nearest hundredth.
Step-by-step explanation:
-2x-5=5x + 6
-2x - 5x = 6 + 5
-7x = 11
x = -11/7
x = 1.571
y = 5(1.571) + 6
y = 7.855 + 6
y = 13.855

f(x)= square root of x-5. find f-1 (x) and it’s domain
Answer:
Option B.
Step-by-step explanation:
Inverse function:
Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.
The domain of the inverse function(x values) is the range of the original function(y values).
Original function:
[tex]f(x) = \sqrt{x} - 5[/tex]
Domain is [tex][0,\infty)[/tex], and when [tex]x = 0, f(x) = -5[/tex]. So the range is [tex][-5,\infty][/tex], that is, [tex]y \geq -5[/tex]
Inverse function:
[tex]y = \sqrt{x} - 5[/tex]
Exchanging x and y
[tex]x = \sqrt{y} - 5[/tex]
[tex]\sqrt{y} = x + 5[/tex]
[tex](\sqrt{y})^2 = (x+5)^2[/tex]
[tex]y = (x+5)^2[/tex]
The inverse function is [tex]f^{-1}(x) = (x+5)^2[/tex]
Domain:
Range of the original function is [tex]y \geq -5[/tex], so the domain of the inverse function is [tex]x \geq -5[/tex]. The correct answer is given by option B.
Answer:
B. f ^ -1 (x) = (x + 5) ^ 2;
x > -5

SOLVE THE SYSTEM USING ELIMINATION!!!!
HURRY ILL GIVE BRAINLIEST!!
Answer:
(5,3)
Step-by-step explanation:
add the equations to eliminate to x's and get 8y=24
divide both sides by 8 to get y=3
then substitute in -2x+3(3)=-1 to solve for x
so x=5 so the solution is (5,3)
Answer:
[tex]x=5 \\y=3[/tex]
Step-by-step explanation:
[tex]-2x+3y=-1\\2x+5y=25[/tex]
Add these equations to eliminate x:
[tex]8y=24[/tex]
Then, solve [tex]8y=24[/tex] for y:
[tex]8y=24[/tex]
[tex]\frac{8y}{8} =\frac{24}{8}[/tex] (divide both sides by 8)
[tex]y=3[/tex]
Now let's find the value of x:
Substitute 3 for y in [tex]-2x+3y=-1[/tex]
[tex]-2x+(3)(3)=-1[/tex]
[tex]-2x+9=-1[/tex] (simplify both sides of the equation)
[tex]-2x+9+-9=-1+-9[/tex] (add both sides by -9)
[tex]-2x=-10[/tex]
[tex]\frac{-2x}{-2} =\frac{-10}{-2}[/tex] (divide both sides by -2)
[tex]x=5[/tex]
Therefore, the value of x = 5 and y = 3

the spinner shown below has 12 congruent sections. the spinner spun 150 times. what is a reasonable prediction for the number of items the spinner will land on an even number. (pls help asap!!)
Answer:45
Step-by-step explanation:
There are 3 even numbers out of A total of 8 numbers.
Each spin would have a 3/8 chance of landing in an even number.
Multiply the chance of landing on even by number of spins:
120 x 3/8 = 360/8 = 45
The answer would be 45 times.

If the line that connects the boat to the parasail is reeled in by 20
meters and the angle of elevation changes to 38° from the boat, how
many meters above the lake is the man to the nearest tenth of a
meter?
A)
67.4 m
B)
85.6 m
9
86.3 m
D)
177.9 m
Answer:
A) 67.4 m
Step-by-step explanation:
Let "x" represent how many meters above the lake is the man
Reference angle = 32°
Opposite = x
Hypotenuse = 129.5 m
Apply ye trigonometric function SOH:
Sin 32° = Opp/Hyp
Son 32 = x/129.5
129.5 × sin 32° = x
x = 68.6245447
This is close to A) 67.4 m

In ΔWXY, the measure of ∠Y=90°, YX = 40, XW = 41, and WY = 9. What ratio represents the cosine of ∠W?
Answer:
[tex]\cos(W) = \frac{9}{41}[/tex]
Step-by-step explanation:
Given
[tex]\angle Y = 90^o[/tex]
[tex]YX = 40; XW = 41; WY = 9[/tex]
Required
Determine [tex]\cos(W)[/tex]
The question is illustrated with the attached image.
So:
[tex]\cos(W) = \frac{Adajacent}{Hypotenuse}[/tex]
[tex]\cos(W) = \frac{WY}{XW}[/tex]
This gives:
[tex]\cos(W) = \frac{9}{41}[/tex]

The volume of a box(V) varies directly with its length(l). If one of the boxes has a volume of 325 cubic inches and a length of 13 inches, what is the constant of proportionality for the group of boxes?
1/25
4,225
25
Answer:
k = 25
Step-by-step explanation:
Given the following data;
Volume = 325 in³
Length = 13 inches
To find the constant of proportionality, k;
Mathematically, direct proportion is given by the expression;
V = kL
k = V/L
Substituting into the formula, we have;
k = 325/13
k = 25

Answer:
93 degrees
Step-by-step explanation:
alternate interior angles are congruent so 39+x=132 x=93
Answer:
Step-by-step explanation:
According to Alternate Interior Angles Theorem (in a graph that shows a transversal crossing two parallel lines, the alternate interior angles are congruent), The angle that includes the sum of 39° and x° is congruent to 132°.
So: 39° + x° = 132°, and x = 93

Answer: [tex]3x^{-2.5}[/tex]
Step-by-step explanation:
Given
Expression is
[tex]\dfrac{12\sqrt{x}}{4x^3}[/tex]
Using exponent property [tex]x^a\cdot x^b=x^{a+b}[/tex]
Writing expression in the form of [tex]k\cdot x^n[/tex]
[tex]\Rightarrow \dfrac{12\sqrt{x}}{4x^3}=\dfrac{3\times 4}{4}\times \dfrac{x^{0.5}}{x^3}\\\\\Rightarrow \dfrac{3\times 4}{4}\times x^{0.5-3}\\\\\Rightarrow 3x^{-2.5}[/tex]
Which of the following relation is a function.
Answer:
Which of the following relations is a function- A
Determine which relation is a function- A
Step-by-step explanation:
A function is a type of relationship where x's do not repeat. So, to solve find where each y has a unique x value. In the first question, A is correct because the x values; -3, 0, 2; never repeat. Then, on the next question A is correct because it is a relation written in slope-intercept form, which is a type of function notation.
