Answer:
<h2>135 ft²</h2><h2 />
Step-by-step explanation:
see attached image
<u>shaded area = total area (1) - unshaded triangular area (2)</u>
1. area of a trapezoid = (a + b) * h/2
where a = 8, b = 18, h = 15
Area of trapezoid = (8 + 18) * 15/2 = 195 ft²
2. Area of unshaded triangle = 1/2 (8) 15 = 60 ft²
shaded area = 195 - 60 = 135 ft²
Answer:
T=5.9235 seconds
Step-by-step explanation:

The time it takes for the cannonball to strike the ground is the point at which H(T)=0


This is a quadratic equation and since we have a bunch of decimals we use the quadratic formula:

a=-4,9, b=27.52, c=8.9

It takes 5.9235 seconds for the cannonball to strike the ground.
Answer:
just try substituting t with the values given . the answer is B
Answer: 87
Step-by-step explanation:
116% = * 1.16
75 * 1.16 = 87
C.) -15,-10,-5,+20
The answer is C because it says rank them from lowest to highest the negatives will always be the lowest. When it’s a negative number and the number infront of the negative is higher than the rest is how yk that it’s the lowest .
