An object is dropped from 39 feet below the tip of the pinnacle atop a 715-ft tall building. The height of the object after sec

Anna007 [38]

Answer:

6.5 seconds

Step-by-step explanation:

Ok so the equation you gave is -16T^2 + 676 in the comments which is what I'll be using for this problem. The problem is really just asking you to find the zeroes of the equation excluding any negative solutions since that doesn't really represent anything in this context since T is time.

So the first step is to set the equation equal to 0

$0 = -16t^2 + 676$ .

Subtract 676 from both equations.

$-676 = -16t^2$

Divide both sides by -16

$42.25 = t^2$

Take the square root of both sides

$\pm6.5 = t$

Ignore the negative and take only the positive solution, since in this context it doesn't make much sense. So after 6.5 seconds the height is 0, meaning it hits the ground after 6.5 seconds.

Among all the rectangles whose perimeters are 100 feet, find the dimensions of the one with the maximum area. explain step by st

kompoz [17]

We let x be the length and y be the width of the rectangle. Then,

Perimeter = 2x + 2y
100 = 2x + 2y
50 = x + y
y = 50 - x

Area = xy
A = x(50 - x)
A = 50x - x^2

We then take the derivative; set it equal to zero:

A ' = 50 - 2x
0 = 50 - 2x
2x = 50
x = 25
y = 50 - x
y = 50 - 25
y = 25

Therefore, the dimensions are 25 and 25.

(5 Points) all (1 – 3K) -396 0-374 0 -198 0 -187

Triss [41]

Answer:−3K−395,−374,−198,−187

Step-by-step explanation:

Remove parentheses.

1−3K−396,0−374,0−198,0−187

Simplify 1-3K-3961−3K−396 to -3K-395−3K−395.

−3K−395,0−374,0−198,0−187

Simplify 0-3740−374 to -374−374.

−3K−395,−374,0−198,0−187

Simplify 0-1980−198 to -198−198.

−3K−395,−374,−198,0−187

Simplify 0-1870−187 to -187−187.

−3K−395,−374,−198,−187
