Answer:

$625 (but it's really $763.14)

Step-by-step explanation:

Use the formula I=P(1+r)^t

April=25000(1.04)^5=$30416.32

May=25000(1.0375)^6=$31179.46

$31179.46-$30416.32=$763.14

So $625 is the closest answer

Jy is hiking glacier national park he now has hiked a total of 17 km and is 2 km short of being 1/2 of the way done with his hik

anastassius [24]

Jy has hiked 17km

He is 2km short of being half of the way done with hicking

Let the total distance he hiked be xkm

Then 1/2x = 17 + 2km

1/2x = 19km

x = 19 × 2 = 38km

The total distance he covered was 38km.

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
