the height in feet of an object projected upward is given by the polynomial -16t^2+60t+90 where t represents time, in seconds. F

Karolina [17]

Given:

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.

Height of an object:

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.

If AC=18x-7,find the x. Round to the nearest hundredth if necessary AB=7x+29 BC=30

Margaret [11]

Answer:

$x=6$

Step-by-step explanation:

AC = AB + BC

$18x-7=(7x+29)+30$

$18x-7=7x+29+30$

$18x-7=7x+59$

Add 7 to both sides:

$18x-7+7=7x+59+7$

$18x=7x+66$

Subtract 7x from both sides:

$11x=66$

Divide both sides by 11:

$\frac{11x}{11}=\frac{66}{11}$

$x=6$
