<u>Given</u>:

The height of an object project upward is given by the polynomial

h=-16t^2+60t+90

where t represents the time, in seconds.

We need to determine the height after t = 2.5 seconds.

<u>Height of an object:</u>

The height of an object after 2.5 seconds can be determined by substituting t=2.5 in the polynomial, we get;

h=-16(2.5)^2+60(2.5)+90

Simplifying, we get;

h=-16(6.25)+60(2.5)+90

h=-100+150+90

h=140

Thus, the height of an object is 140 feet.

You receive an 11 percent commission on all sales you make if your commission for the month is 512.50 dollars what was your tota
JulijaS [17]

Total sales were $4659.1

Step-by-step explanation:

Given,

Commission = 11%

Amount of commission = $512.50

Let,

total sales = x

Therefore,

11% of x = 512.50

\frac{11}{100}x=512.50\\0.11x=512.50

Dividing both sides by 0.11

\frac{0.11x}{0.11}=\frac{512.50}{0.11}\\x= $4659.1

Total sales were $4659.1

Let the distance of the engineer from the base of the building be x, then
tan 38 = 300/x
x = 300/tan 38 = 300/0.7813 = 383.98

Therefore, the distance from the engineer to the base of the building to the nearest whole foot is 384 feet.
