An object is dropped from the top of a tall building. The height S of the object after t seconds is given by the equation s=-16t
fiasKO [112]

Answer:

  6.5 seconds

Step-by-step explanation:

When s=0, we have ...

  0 = -16t^2 +676

  t^2 = 42.25 . . . . . add 16t^2, divide by 16

  t = √42.25 = 6.5

6.5 seconds will pass before the object hits the ground.

$22,102 is invested, part at 11% and the rest at 7%. If the interest earned from the amount invested at 11% exceeds the interest
Yuliya22 [10]
X + y = 22,102
.11x = .07y + 913.46  =      x= (7/11)y + 8304.18

((7/11)y + 8304.18) + y = 22,102

(18/11)y = <span>13797.82
</span>
y= 13797.82/(18/11)

y=8432.00 

8,432.00 dollars are invested at 7%
13,670.00 dollars are invested at 11%

Check
.07 x 8432=  590.24
.11 x 13,670 = 1503.70

1503.70 - 590.24 = 913.46
