We are given equation V = r²h.
Let us break it into parts to get the correct variation.
V = r²h could be written first V= r² × h.
And we could break it in two different proportions:
V ∝ r² can be read as V is directly proportional to r².
V ∝ h can be read as V is directly proportional to h .
Non of the variable r² or h in denominator.
<em>When we have any variable in denominator, it's an inverse variation and if we don't have any variable in denominator, it would be a direct variation.</em>
<h3>Therefore, we can say V = r²h is a direct variation.</h3>
Answer:
The scale factor is 4
Step-by-step explanation:
* Lets talk about dilation
- A dilation is a transformation that changes the size of a figure.
- It can become larger or smaller, but the shape of the
figure does not change.
- The scale factor, measures how much larger or smaller
the image will be
- If the scale factor greater than 1, then the image will be larger
- If the scale factor between 0 and 1, then the image will be smaller
* In the problem
- The vertex A of the triangle is (-6 , 4) and its image A' is (-24 , 16)
∵ -24 ÷ -6 = 4
∵ 16 ÷ 4 = 4
∴ The scale factor is 4
∵ 4 > 1
∴ The image of the triangle will be larger
* The scale factor is 4
Answer:
They need to wash 72 cars
Step-by-step explanation:
2000 - 1640 = 360
360/5 = 72
Answer:
degree 3
Step-by-step explanation:
Note that
(- 3)³ + 4 = - 27 + 4 = - 23
(- 2)³ + 4 = - 8 + 4 = - 4
0³ + 4 = 0 + 4 = 4
1³ + 4 = 1 + 4 = 5
2³ + 4 = 8 + 4 = 12
3³ + 4 = 27 + 4 = 31
Then
f(x) = x³ + 4 ← a polynomial of degree 3
