q = 10p because all of them are multiplied by ten
They each read 22 1/2 minutes which would be 22.5/60
Based on the vertex form equation, the statements that are true are:
A.) the drone reaches its minimum 25 miles from the launch site
C.) at its minimum, the drone’s depth is -180 meters.
<h3>Rewriting the equation in vertex form</h3>
Given:
x = horizontal distance, in miles, from the launch site
d(x)= depth below the surface of the water, in meters.
Equation= 0.4x ²- 20x + 70
Hence
Rewritten the given equation ( 0.4x ²- 20x + 70) in vertex form will be:
Vertex form: d(x)=[2(x-25)²÷5] -180
Vertex= -180, 25
Minimum=-180 at x=25
Therefore the correct option is A, C.

The side of the barn is made of 2 shapes, a triangle and a rectangle. Find the area of each shape, then add together to find the total area.
To find the area of the triangle, we multiply 1/2 x (triangle base x triangle height), we can find the triangle height by subtracting the height on the right by the height on the left, so 26.5-14.5 = 12.5ft.
The area of the triangle is 1/2 x (22.8x12.5) = 142.5 square ft.
The area of the rectangle is calculated by multiplying one side by the other, which is 22.8x14.5 = 330.6 square feet.
The total area of the side of the barn is 330.6 + 142.5 = 473.1 square feet.
Since we now know the area of the side of the barn, we can find the cost of paint needed. A one gallon paint can covers 350 square feet and costs $20, but we need to paint 473.1 square feet so we'll need to buy a second can. This means we can easily paint the side of the barn with 2 cans, costing $40 in paint.
34cm
52/13=4, the smallest side
then 13+4+13+4= 34cm
