1 answer:

4 0

The area of a triangle:
$A_\Delta=\dfrac{bh}{2}$
We have:
$A_{\Delta}=234.4\ ft^2.\\\\h=16\ ft.$
substitute:
$\dfrac{16b}{2}=234.4\\\\8b=234.4\ \ \ |:8\\\\b=29.3\ ft.$
Answer: 29.3 ft.

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

When the object will hit the ground its height=0

0=-16 $t^{2}$ +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

A figure is made up of one square and one triangle. The square has a side Length of 13 feet. The triangle has a base of 13 feet

Marysya12 [62]

Im pretty sure it’s A because a squares area is base x height which would be 13x13= 169 then add the area of the triangle which would be 53.3, so 169+53.3 = 222.3
