The predicted distance of the ball would be 27.1.93 yards when the ball travels for a duration of 5 seconds.

Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.

The distance, y, is measured in yards and the speed, s, is measured in miles per hour.

The regression line is defined as ŷ = 3.98 + 53.59s  ... (i)

The slope and y-intercept of the regression line must be determined.

The general equation for a linear regression line is y = a + bx...(ii), where x is a variable. The variable is indicated by s in the above equation.

When I and (ii) are compared, we obtain a = 3.98 and b = 53.59.

It indicates that the slope is 53.59 and the y-intercept is 3.98.

The slope, b = 53.59, implies that for every mile per hour of speed, the distance rises by 53.59 yards.

The ball travels for a duration of 5 seconds

Substitute the value of s = 5 in equation (i) to get

ŷ = 3.98 + 53.59(5)

ŷ = 271.93

Thus, the predicted distance of the ball would be 27.1.93 yards.

Step-by-step explanation:

The given expression is

Factor out the greatest common factor between 15x and 20y.

Then, use the product property to expand the logarithm.

At last, simplify the first logarithm because its base is equal to its argument.

Therefore, the simplest form of the logarithm is

With the width and length being held constant, the height of the box decreases at rate  5 cm/s

Let:

l = length

w = wide

h = height

Then, the volume of the box is given by:

V = l . w. h

The length and the width are assumed to be constant. Hence, the derivative with respect to time is:

dV/dt = l . w dh/dt

Parameters given:

dV/dt = - 541 cm³/dt

l = 9 cm

w = 12 cm

Plug these parameters into the formula:

-541 = 12 . 9 . dh/dt

dh/dt = 5 cm/s

The expression f(-16) means we have to evaluate the function when x = -16.

ANSWER

-4.5

EXPLANATION

We want to find the opposite of the number 4.5

The opposite of a number is the number that is the same distance from 0 on the number line but on the other side.

So, if the number is on the right hand side, its opposite is on the left hand side.

In simpler terms, the opposite of a number is the negative of a number.

So, the opposite of 4.5 is -4.5.

SOLUTION

The equation of the parabola is defined using

Since the vertex is at the origin the equation becomes

Since the directrix is y=5

The distance from the focus to the vertex is equal to the distance from the vertex to the directrix

It follows

Thus the equation becomes

Therefore the equation of the required parabola is

In the sample space, the annotation for the event where both E and G but not F occurs is given as:( E ∩ G ) ∩ Fc (Option B).

An event is a specified set of results of a random experiment in probability theory. Because the sample space is the collection of all potential outcomes of a random experiment, another definition of an event is any subset of a sample space.

Colloquially, the sample space for a given set of events is the collection of all potential values for the events. Technically, a sigma-algebra is formed by the set of probable occurrences for a given random variate, and sample space is defined as the biggest set in the sigma algebra.

The proof of △AED is congruent to △BEC

What is congruency?

Two figures or objects are congruent in geometry if they have the same shape and size, or if one has the same shape and size as its mirror counterpart. In more technical terms, two sets of points are said to be congruent if and only if one of them can be changed into the other by an isometry, which is a combination of rigid movements such as translation, rotation, and reflection. This implies that one item may be relocated and reflected (but not scaled) to perfectly align with the other. So two separate plane figures on a piece of paper are congruent if they can be cut out and then entirely matched up. It is OK to flip the paper over.

Given, △ABC is congruent to △BAD.

and △AEB is common in both, so

△AED is congruent to △BEC (proved)

We will substitute it in the above equation

q = [tex]$$\int[/tex] 10 cos(120πt - 12π) + 5 dt

now here limits of time is from t = 0.1 to t = 60 s

so here it will be given as

[tex]$\int 10 cos(120\pi t - 12\pi ) + 5 dt[/tex]

Rewrite using trig identities

[tex]$=\int_{0.1}^{60} 10 \cos (120 \pi t)+5 d t$$[/tex]

Apply the Sum Rule:

[tex]$\int f(x) \pm g(x) d x=\int f(x) d x \pm \int g(x) d x$[/tex]

substitute the values in the above equation, we get

[tex]$=\int_{0.1}^{60} 10 \cos (120 \pi t) d t+\int_{0.1}^{60} 5 d t$[/tex]

simplifying the equation,

Answer:

[tex](f \circ g)(24)=-36[/tex]

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=-9x+9\\g(x)=\sqrt{x+1}\end{cases}[/tex]

Function Composition is applying one function to the results of another.

The composite function (f o g)(x) means to substitute the function g(x) in place of the x in function f(x).  

Therefore (f o g)(24) means to substitute the result of g(24) in place of the x in the function f(x).

Calculate g(24) by substituting x = 24 into function g(x):

[tex]\begin{aligned}\implies g(24)&=\sqrt{24+1}\\&=\sqrt{25}\\&=5 \end{aligned}[/tex]

Therefore:

[tex]\begin{aligned}\implies (f \circ g)(24) & = f[g(24)]\\& = f(5)\\& = -9(5)+9\\&=-45+9\\&=-36\end{aligned}[/tex]

Answer:

(f∘g)(24) = -36

Step-by-step explanation:

We are given f(x) = -9x + 9 and  [tex]g(x)= \sqrt{x+1}[/tex].

We want to find (f∘g)(24).

This means that we first want to find g(24), then substitute the value of that into f(x).  

Start by substituting 24 for x in g(x).

[tex]g(24)= \sqrt{24+1}[/tex]

Add 24 and 1 together.

[tex]g(24)= \sqrt{25}[/tex]

Take the square root of 25.

g(24) = 5

Now, substitute 5 as x in f(x) = -9x + 9.

f(5) = -9(5) + 9

Multiply.

f(5) = -45 + 9

Add the numbers together.

f(5) = -36

f(5) in this case has the same value as (f∘g)(24)

This means that (f∘g)(24) = -36

The angular coefficient is also referred to as the slope of the line.

Given that the slope of the lining joining these pair of points are the same:

Then:

We solve the equation for p:

The salesperson needs to make weekly sales of $9,500 to earn the same amount with each option.

The amount he earns by option A can be calculated as follows;

As he works 40 hours per week and the hourly wage is $19; therefore the amount he will earn can be determined by multiplication as follows;

Option A earning: 40 × 19 = $760

Thus, the salesperson earns $760 through option A.

Consider x to be the amount of weekly sales;

As the commission rate is 8% of sales therefore 8% of x should be equal to $760 for the salesman to earn the same amount with both options.

(8/100)x = 760

0.08x = 760

x = 760 / 0.08

x = 9,500

Hence the salesman needs to make weekly sales of $9,500 to earn the same amount with both options.

Although there is a mistake in your question, you might be referring to this question;
