A) 31 degrees
b) 118 degrees
Answer:
the initial height
Step-by-step explanation:
given the height is represented by the function
f(t) = - 16t² + 40t + 3
Then the initial height is when t = 0, that is
f(0) = 0 + 0 + 3 = 3 ← initial height
A² + b² = c²
5² + 8² = x²
x² = 25 + 64
x² = 89
x = √89
x = 9.43
Answer:
width is 8, length is 32
Step-by-step explanation:
* = multiply or times
Let the width be x, then the length would be 4x
Perimeter = 2*length+2*width
80 = 2*4x+2*x
80 = 8x+2x
80 = 10x
8 = x (width)
32 = 4x (length)
