Anestetic [448]

Answer:

the answer is 306.25 feet and b is 8 sec

Step-by-step explanation:

Explanation

The height of the ball as a function of the time is given by the following formula:

A. Maximum height of the ball

To find the value of the maximum height, we maximum the function h(t) computing its first derivative and equalling the result to zero:

Solving the last equation for t, we get time t when the height is maximum:

So the maximum height is given by the value of h(t) when t = 2.5:

The maximum height is 196ft.

B. Time until the ball hits the ground

The ball will hit the ground when h(t) = 0. So we must find the value of t such that:

Solving this equation is equivalent to finding the roots of a second-order polynomial:

Where:

• a = -16,

,

• b = 80,

,

• c = 96.

The roots of this polynomial are given by the following formula:

s

Answer

A. The maximum height of the ball is 196 ft.

A truck driver starts driving his truck at 2:00 and drives for 45 minutes at 45 miles per hour. 3. at what time will he have tra
tamaranim1 [39]

If you travel at a constant speed, you follow this formula:

s = vt

where s is the space traveled, v is the speed and t is the time passed. Knowing the speed and the desired space, we can solve the equation for the time:

t = \dfrac{s}{v}

Plug your values:

t = \dfrac{30}{45} = \dfrac{2}{3}

And two-thirds of an hour are 40 minutes.

To convert his speed in miles per minutes, you only need to use that one hour is composed of 60 minutes:

\dfrac{45 \text{ miles}}{1\text{ hour}} = \dfrac{45 \text{ miles}}{60\text{ minutes}} = \dfrac{3 \text{ miles}}{4 \text{ minutes}} = 0.75 miles per minute

Find two consecutive even integers such that twice the second is the same as 186 less than the first integer.​
Alisiya [41]

Step-by-step explanation:

let the 2 integers be x and x + 1

2(x + 1) + 186 = x

2x + 188 = x

x = -188

therefore the 2 integers are -188 and -187
