An object is thrown upward from the top of 80 ft tower.The height h of the object after t seconds is represented by the quadrati
Sedaia [141]

Answer:The object will hit the ground after 5 seconds


Step-by-step explanation:

Given height of tower =80 ft

h=-16t^{2}+64t+80

When the object will hit the ground its height=0

0=-16t^{2}+64t+80

Multiplying both sides by -1

16t²-64t-80=0

Dividing by 16 both sides

t²-4t-5=0

(t-5)(t+1)=0

t=5 or -1

So t=5 since time cannot be negative

The object will fall after 5 seconds

Answer:

a) 36°

b ) 18°

Step-by-step explanation:

The formula is given as:

The measure of each exterior angle =360°/n, where n = number of sides of a polygon.

a) decagon

Decagon = 10 sides

Hence, the measure of each exterior angle = 360°/10

= 36°

b) 20-gon

20-gon = 20 sides

Hence, the measure of each exterior angle = 360°/20

= 18°
