Since 4>1, this represents exponential growth.
Answer:
Step-by-step explanation:
Answer:
y = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = 
sin45° =
= 
Multiply both sides by y
y × sin45° = 9, that is
y ×
= 9
Multiply both sides by 
y = 9
Answer:
w = 80/9 ft.
L = 640/9 ft.
Step-by-step explanation:
L = length w = width
2w = L/4 so 8w = L
160 = 2L + 2w
160 = 2(8w) + 2w
160 = 16w+2w
160 = 18w
80/9 = w
