<u>Proportional Geometric Shapes
</u>
A) We are given two similar shapes of a logo. They are to be proportional. We only need to find the proportion ratio of two of them to find the rest of the lengths.
The upper sides have 7.5 cm and 5 cm respectively. This gives us the ratio

Which means all the measures of the smaller logo are 1.5 smaller than those of the larger. This means
b=6.3/1.5=4.2 cm
a=7.2*1.5=10.8 cm
B) To paint the logos, we need to cover its surface, so the ratio of the surface is 1.5*1.5=2.25
This means the cost to paint the larger logo is

Answer:
The vertex form of a quadratic is given by
y = a(x – h)^2 + k, where (h, k) is the vertex. h may act as "x" in this case.
Step-by-step explanation:
The vertex form of a quadratic is given by
y = a(x – h)^2 + k, where (h, k) is the vertex.
You must simply get an equation in this format to find h and k.
