A student throws a heavy ball downward off the top of a building with a speed of 18m/s. The ball reaches a speed of 41m/s just before striking the ground. Neglect drag.

Answers

Complete question:

A student throws a heavy ball downward off the top of a building with a speed of 18m/s. The ball reaches a speed of 41m/s just before striking the ground. Neglect drag, find the height of the building.

Answer:

The height of the building is 69.235 m

Step-by-step explanation:

Given;

initial velocity of the ball, u = 18 m/s

final velocity of the ball, v = 41 m/s

The height of the building is equal to distance traveled by the ball downward.

Apply the following kinematic equation;

v² = u² + 2gh

where;

g is acceleration due to gravity

h is height of the building

41² = 18² + 2(9.8)h

1681 = 324 + 19.6h

19.6h = 1681 - 324

19.6h = 1357

h = 1357 / 19.6

h = 69.235 m

Therefore, the height of the building is 69.235 m

Evaluate the function Find f(x)= 3x^2-x+2 a. x=3 b. x=-5 c. f(2) d. f(m) e. f(x+2)

Answers

Answer:

see explanation

Step-by-step explanation:

Given

f(x) = 3x² - x + 2

To evaluate given values of x, substitute the values of x into f(x)

(a)

f(3) = 3(3)² - 3 + 2 = 3(9) - 1 = 27 - 1 = 26

(b)

f(- 5) = 3(- 5)² - (- 5) + 2 = 3(25) + 5 + 2 = 75 + 5 + 2 = 82

(c)

f(2) = 3(2)² - 2 + 2 = 3(4) = 12

(d)

f(m) = 3m² - m + 2

(d)

f(x + 2) = 3(x + 2)² - (x + 2) + 2 ← expand (x + 2)² using FOIL

= 3(x² + 4x + 4) - x - 2 + 2

= 3x² + 12x + 12 - x ← collect like terms

= 3x² + 11x + 12

What is wrong with the equation? π 4 sec(θ) tan(θ) dθ = 4 sec(θ) π π/3 = −12 π/3 There is nothing wrong with the equation. f(θ) = 4 sec(θ) tan(θ) is not continuous on the interval [π/3, π] so FTC2 cannot be applied. f(θ) = 4 tan(θ) is not continuous on the interval [π/3, π] so FTC2 cannot be applied. f(θ) = 4 sec(θ) is not continuous at θ = π/3 so FTC2 cannot be applied. The lower limit is not equal to 0, so FTC2 cannot be applied.

Answers

The given equation is not defined in the interval [tex]\left[\dfrac{\pi}{3},\pi\right][/tex]. Therefore, FTC2 is not applied and this can be determined by using the property of the trigonometric function.

Given :

Equation -- [tex]\rm \int^{\pi}_{\pi/3}7\;sec\theta\; tan\theta \;d\theta[/tex]

The following steps can be used in order to determine what is wrong with the given equation:

Step 1 - Write the given equation.

[tex]\rm \int^{\pi}_{\pi/3}7\;sec\theta\; tan\theta \;d\theta[/tex]

Step 2 - In the given equation [tex]\rm sec\theta[/tex] is not defined at [tex]\theta = \pi/2[/tex].

Step 3 - In the given equation [tex]\rm tan\theta[/tex] is not defined at [tex]\theta = \pi/2[/tex].

Step 4 - From the above steps, it can be concluded that the given equation is not defined in the interval [tex]\left[\dfrac{\pi}{3},\pi\right][/tex]. Therefore, FTC2 is not applied.

Jan completes 60 trials of pulling colored marbles out of a bag. She pulled green 15 times. If there are 250 marbles in the bag, how many of them are probably green?

Answers

Answer:

the answer is 63 green marbles

Step-by-step explanation:

Answer:

Green marbles are probably = 62.5.

Step-by-step explanation:

Since Jan completes 60 trials and pulled green 15 times, the probability of any marble being green can be calculated as:

= 15/60

= 0.25

With 250 marbles in the bag, using the probability value of green marbles calculated above, the number of green marbles can be estimated as:

= 0.25 of 250

= 62.5

This shows that since there is a 25% probability of obtaining a green marble from 60 trials of pulling colored marbles out of the bag containing 250 marbles, then the total number of green marbles will be equal to 62 or 63.

Points Pand Q lie in plane A. How many lines contain P

2. Lines PQ and QP

3. The 2 lines PQ and QP plus another line that does

not lie in plane A.

1. Line PQ

. We can't name them all!

Answers

Answer:

The correct answer is :

1. Line PQ (One line PQ).

Step-by-step explanation:

The first step to solve this question is to draw the plane A with the points P and Q lying on it.

We know that given two different points there is only one line that contains this two different points.

Let's analyze each option.

''2. Lines PQ and QP''

This option is wrong because there aren't two different lines. In fact it is only one line that can be named line PQ or line QP.

''3. The 2 lines PQ and QP plus another line that does not lie in plane A.''

This option is assuming that exist three lines that contain P and Q. This option is also wrong.

''1. Line PQ''

This option is correct. It will be clarify with the drawing I will attach.

''We can't name them all!''

This option is assuming that exist infinite lines that contain P and Q. This option is wrong.

In the drawing I call the line that contains P and Q as line L.

Given that P and Q lie in plane A necessarily the line L must lie on the plane A.

Only one line contains points P and Q

The given parameters are:

Plane APoints P and Q

There are at least two points in a line

This means that, a line can contain points P and Q, and any other points

Hence, only one line contains points P and Q
