Answer: A soccer ball is kicked with an initial horizontal speed of 5 m/s and an initial vertical speed of

3 m/s. Assuming that projection and landing height are the same and neglecting air resistance,

identify the following quantities:

a. The ball’s horizontal speed is 0.5 seconds into its flight

5 m/s because horizontal speed is constant

b. The ball’s horizontal speed midway through its flight

5 m/s because horizontal speed is constant

c. The ball’s horizontal speed immediately before contact with the ground

5 m/s because horizontal speed is constant

d. The ball’s vertical speed at the apex of its flight

0 m/s because the ball changes directions at the apex and must reach zero speed

before changing directions

e. The ball’s vertical speed midway through its flight

0 m/s – the apex is midway because the projection and landing height are the same, so

the reason is the same as d.

f. The ball’s vertical speed immediately before contact with the ground

3 m/s because the projection and landing heights are the same, projection and landing

speeds are the same

Step-by-step explanation:

The dimensions of the cross section of the field, shaped like a parabola and modeled by the quadratic function; y = -0.000234·(x - 80)² + 1.5 are;

Width ≈ 160 feet

Maximum height = 1.5 feet

Parabolas describe the motion of the path of flight of a ball thrown in the air, and horses show jumping.

The function for the cross section of the field; y = -0.000234·(x - 80)² + 15

Where x and y are measured in feet

The width of the field can be found by finding the x-intercepts of the parabola. To do this, we can set y = 0 and solve for x;

0 = -0.000234·(x - 80)² + 1.5

Therefore; 0.000234·(x - 80)² = 1.5

(x - 80)² = 1.5/0.000234

x - 80 = ±√(1.5/0.000234)

x = 80 ± √(1.5/0.000234)

x ≈ 0 and x ≈ 160

The equation for the cross section of the field is presented in the vertex form of a quadratic equation; y = a·(x - h) + k

Where; (h, k) is the vertex and by comparison, (h, k) = (80, 1.5)

h = The x-value of the vertex

k = The y-value of the vertex = The maximum height = 1.5 feet

Answer:

y = (1/3)x - (1/3)

(1/3)

Step-by-step explanation:

We can find the slope by subtracting Q points by P points.

(2 - (-1)) / (7 - (-2))

3 / 9

1/3 = slope

To find y intercept we can use the slope and find the difference left

y = (1/3)x

-1 = (1/3)(-2)

-1 = -(2/3)

This is not true

To make it true we must subtract -(1/3)

This means our equation is

y = (1/3)x - (1/3)

Answer:

  m∠I = 22

  m∠J = 53

  m∠K = 105

Step-by-step explanation:

m∠I = (x + 7)

m∠J = (3x + 8)

m∠K = (7x)

m∠I + m∠J + m∠K = 180°

(x + 7) + (3x + 8) + (7x) = 180

x + 7 + 3x + 8 + 7x = 180

11x + 15 = 180

11x = 165

x = 15

m∠I = 15 + 7 = 22

m∠J = 3(15) + 8 = 53

We have, National Collegiate Athletic Association (NCAA) take a survey of randomly selected student athletes concerning their gambling-related behaviors.

repoted participation of students, x = 3547

Sample size,n = 5594

Margin of error, E = 1% = 0.01

The sample proportion is a number of successes divided by the sample size, p-cap = 3547/5594

= 0.6341

The margin of error is for a confidence interval for a proportion, which is determined by using the following formula is

\(CL = Zα/₂ \sqrt{ \frac{ \hat{p} \: (1- \hat{p})}{n} }\)

= Zα/₂√(1 - 0.6341)0.6341/5594

= 0.0064 Zα/₂

This margin of error also has to be equal to 1% or

0.0064 Zα/₂ = 0.01

=> Zα/₂ = 0.01/0.0064 ~ 1.55

The confidence level is the probability of obtaining this value or less extreme, determine the probability using z- table,

Answer:

Step-by-step explanation: We can start the problem by using the principle of Proportional Equivalents. We can write two equations based on the given information:

Let's say that the rate of filling the pool with one large pump is x and the rate of filling the pool with one small pump is y.

Then, we can write the following two equations:

2x + 1y = 1/4 (because two large and one small pump can fill the pool in 4 hours)

1x + 3y = 1/4 (because one large and three small pumps can fill the pool in 4 hours)

Now we have two equations with two unknowns, x and y. We can solve for x and y using either substitution or elimination method. Let's use substitution method.

Solving for x:

From equation (1), we have 2x = 1/4 - 1y

Substituting this value of x in equation (2), we get:

1 (1/4 - 1y) + 3y = 1/4

Expanding and simplifying, we get:

1/4 - 1 + 3y = 1/4

3y = 1/2

y = 1/6

So, the rate of filling the pool with one small pump is 1/6.

Now that we have found the value of y, we can find the value of x.

x = 1/4 - 1y = 1/4 - 1 * 1/6 = 1/4 - 1/6 = 1/12

So, the rate of filling the pool with one large pump is 1/12.

Now that we have found the rate of filling the pool with each large and small pump, we can find the time it will take 4 large and 4 small pumps to fill the pool.

Let's call the rate of filling the pool with 4 large and 4 small pumps as R.

Then, R = 4 * 1/12 + 4 * 1/6 = 1/3

So, it will take 1/R = 3 hours to fill the pool with 4 large and 4 small pumps.

Answer:

p = 1.26

Step-by-step explanation:

We also know that divided weight will be equal to 0.42 pounds.

p / 3 = 0.42

To solve:

multiply both sides by 3 to cancel the division by 3

p = 1.26

Answer:

165 minutes

Step-by-step explanation:

To solve for the number of minutes that Joaquin played for, we can use this expression:

(let 'a' represent how much time passed from the time Joaquin started playing basketball until the time he arrived at home)

Subtracting 1:10 from each side:

1:10 - 1:10 cancels out to 0, while 3:35 - 1:10 is equal to 2:25.

So, the expression is now:

So, 2 hours and 25 minutes passed.

If we know that 1 hour is equivalent to 60 minutes, we can use this expression to solve for however many minutes are in 2 hours:

Now we need to add on the number of minutes and the time it took him to get home:

Therefore, 165 minutes passed from the time Joaquin started playing basketball until the time he arrived at home.

The measure of the angle B of the triangle is 78.15 degrees

From the question, we have the following parameters that can be used in our computation:

A = 25 degrees

a = 9.5 units

b = 22 units

Using the law of sines, the angle B is calculated as

sin(A)/a = sin(B)/b

So, we have

sin(25)/9.5= sin(b)/22

This gives

sin(b) = 22 * sin(25)/9.5

Evaluate

sin(b) = 0.9787

Take the arc sin of both sides

b = 78.15

Hence, the measure of the angle is 78.15 degrees

Answer:

All points satisfy the inequality

Step-by-step explanation:

Given

\(5x + 2y \le 26\)

Required

Select all points that satisfy the above inequality

\((a)\ (0,5)\)

This implies that

\(x = 0; y = 5\)

So, we have:

\(5x + 2y \le 26\)

\(5 * 0 + 2 * 5 \le 26\)

\(0 + 10 \le 26\)

\(10 \le 26\)

This satisfy the inequality

\((b)\ (3,1)\)

This implies that

\(x = 3;\ y =1\)

So, we have:

\(5x + 2y \le 26\)

\(5 * 3 + 2 * 1 \le 26\)

\(15 + 2 \le 26\)

\(17 \le 26\)

This satisfy the inequality

\((c)\ (3,-4)\)

This implies that:

\(x = 3; y-4\)

So, we have:

\(5x + 2y \le 26\)

\(5 * 3 + 2 * -4 \le 26\)

\(15 -8 \le 26\)

\(7 \le 26\)

This satisfy the inequality

\((d)\ (-4,1)\)

This implies that:

\(x = -4; y =1\)

So, we have:

\(5x + 2y \le 26\)

\(5 * -4 + 2 *1 \le 26\)

\(-20 + 2 \le 26\)

\(-18 \le 26\)

This satisfy the inequality

The weight on the inflation gap has increased from 0.5 to 0.75. The real interest rate is 16.86% and Nominal interest rate is 20%

a. In the base scenario, the real interest rate will be 20%, and the nominal interest rate will be 20%.

b. In scenario B, inflation rate will be higher (4%) compared to the base scenario (3.14%).

Output gap is 0% in both the scenarios, however, in the base scenario inflation gap is 0% (3.14 - 3.14) and in scenario B, inflation gap is 0.86% (4 - 3.14).

Now, let's calculate the real interest rate.

Real interest rate in base scenario = 20% - 3.14%

= 16.86%.

Real interest rate in scenario B = 20% - 3.14% + 1.5 + 0.5 (4-3.14) + 0.5 (0-0/0)

= 19.22%.

The real interest rate has moved in the direction to move inflation rate towards its target.

c. In scenario C, the output gap will be 20% compared to 0% in the base scenario.

Inflation gap is 0% in both the scenarios

Inflation rate is 3.14% and in scenario C, inflation rate is 2%.

Let's calculate the real interest rate. Real interest rate in the base scenario = 20% - 3.14%

= 16.86%.

Real interest rate in scenario C = 20% - 2% + 1.5 + 0.5 (3.14 - 3.14) + 0.5 (20-0/20)

= 20.15%.

Real interest rate in scenario C = 20% - 2% + 1.5 + 0.75 (3.14-3.14) + 0.25 (20-0/20) = 18.78%.

The new policy rule has changed the weight of the output gap in the Taylor Rule from 0.5 to 0.25.

Answer:

Step-by-step explanation:

To solve the equation 7x-3(x-6)=30, we need to use the distributive property to simplify the left-hand side of the equation:

7x - 3(x-6) = 30

7x - 3x + 18 = 30

4x + 18 = 30

Next, we need to isolate the variable term on one side of the equation. To do this, we can subtract 18 from both sides:

4x + 18 - 18 = 30 - 18

4x = 12

Finally, we can solve for x by dividing both sides by 4:

4x/4 = 12/4

x = 3

Therefore, the solution to the equation 7x-3(x-6)=30 is x = 3. Answer A is correct.
