Step-by-step explanation:

Answer:

Step-by-step explanation:

Plot the point (4, -1) in the 4th Quadrant.

The slope (-3/4) tells us what to do next:

With your pencil point initially on (4, -1), move it 4 units to the right, to (8, -1).

With your point initially on (8, -10, move it down 3 units, to (8, -4).  Plot (darken) (8, -4).

Draw a line through (4, -1) AND (8, -4)

The equation of a line for the given slope and the coordinate point is 4y=-3x+8.

Given that, the line with the slope -3/4 passes through the point (4,-1).

We need to find the line of equations.

The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis. Let us consider a straight line of slope 'm' and y-intercept 'b'. The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as y = mx + b.

Now, substitute m=-3/4 and the point (4,-1) in y = mx + b and find the value of b.

That is, -1 = -3/4 (4)+b

⇒b=2

Then the equation becomes y=-3/4 x+2

⇒4y=-3x+8

Therefore, the equation of a line for the given slope and the coordinate point is 4y=-3x+8.

Speed is the change in distance of a body with respect to time.

If the library made a copy of leslie's 3 page essay in just 1/10 of a minute, this means that she made 3 pages in (1/10 * 60)secs i.e 6secs

To get the speed, we need to calculate the amount of page of essay that are produced in a minute (60secs).

If 3 page essay = 6secs

x page essay = 60 secs

cross multiply

3*60 = 6x

180 = 6x

x = 180/6

x = 30

This shows that 30 page essays are produced in just a minute. Hence the speed of the copy machine is 30page essay/min.

The probability is 1/10.

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

Given:

A magician asks an audience member to pick any number from 6 to 15

Possible outcome = {6,7,8,9,10,11,12,13,14,15}

So, chance of picking the number the magician has in mind = numerator

Step-by-step explanation:

So we have the function:

[tex]y=-2x^3[/tex]

As we can see, the degree of this function is 3. This is a cubic function. In other words, this is nonlinear. Let's go through each of the choices:

Already, we can eliminate C and D since the function is nonlinear as it's a cubic function. So, we only need to check A and B.

A: If we change the -2 to 2 like so:

[tex]y=-2x^3\\y=2x^3[/tex]

The function remains a cubic. The only thing we've changed is how the graph is oriented. With -2, the graph goes from top to bottom. With 2, the graph goes from bottom to top. Nevertheless, it's still a cubic function. What we need to change is the exponent and not the coefficient. A is not correct.

B: If we change the 3 to 1 like so:

[tex]y=-2x^3\\y=-2x^1\\y=-2x[/tex]

This is now a linear equation. The degree is 1 and as you can probably picture, it's a downwards sloping line. The correct answer is B.

Now, [tex]$ h(-x) = 12(-x)^8 +49 $[/tex]

                   = [tex]$ - 12x^8 +49 $[/tex]

So, the function is neither odd nor even.

Therefore, reflecting the equation over x - axis would result a function that in neither even nor odd.

Answer:

About 27.5 minutes

Step-by-step explanation:

When looking at the graph, you can see that the red line intersects about 27.5 minutes with $55.

Barry consumed almost 27.28 minutes.

The general equation of a straight line is -

y = mx + c

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of lines are -

(y - y₁) = m(x - x₁)                                {Point - slope form}

(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁)      {Two point - slope form}

x/a + y/b = 1                                        {intercept form}

x cos(β) + y sin(β) = L                          {Normal form}

We have a graph shows Barry's monthly phone bill and the number of minutes used.

The points that lie on the graph are -

(0, 25) and (60, 90)

Slope of the line will be -

m = (90 - 25)/(60 - 0)

m = 65/60 = 1.1

[c] = 25

The equation of the line would be -

y = 1.1x + 25

For y = 55, we get -

55 = 1.1x + 25

1.1x = 30

x = 30/1.1

x = 27.28

Therefore, Barry consumed almost 27.28 minutes.

The expected profit of the man from the horse race is $22,400.

Given data:

To find the man's expected profit, calculate the probability of each outcome and multiply it by the corresponding profit.

To determine the probability of each outcome based on the given information:

Probability of winning both races = 0.30 * 0.40

Probability of winning both races = 0.12

Probability of winning one race = 0.30 * 0.60 + 0.70 * 0.40

Probability of winning one race = 0.46

Probability of losing both races = 0.70 * 0.60

Probability of losing both races = 0.42

Next, calculate the expected profit for each outcome:

Profit from winning both races = $90,000 - $20,000

Profit from winning both races = $70,000

Profit from winning one race = $55,000 - $20,000

Profit from winning one race = $35,000

Profit from losing both races = $15,000 - $20,000

Profit from losing both races = -$5,000 (a loss of $5,000)

Now, determine the man's expected profit by multiplying the probability of each outcome by the corresponding profit and summing them up:

Expected profit = (0.12 * $70,000) + (0.46 * $35,000) + (0.42 * -$5,000)

Expected profit = $8,400 + $16,100 - $2,100

Expected profit = $22,400

Hence, the man's expected profit is $22,400

B.    [tex]\mathtt{\dfrac{dA}{dt}|_{t = 5.79}= 839.86 }[/tex]

Step-by-step explanation:

Given that:

An investment of  Amount = $8000

earns  at an annual rate of interest = 7% = 0.07 compounded continuously

The objective is to :

A)  Find the instantaneous rate of change of the amount in the account after 2 year(s).

we all know that:

[tex]A = Pe^{rt}[/tex]

where;

[tex]A = (8000) \ e ^{0.7t}[/tex]

The instantaneous rate of change = [tex]\dfrac{dA}{dt}[/tex]

[tex]\dfrac{dA}{dt} = \dfrac{d}{dt}(8000 \ e ^{0.07t} )[/tex]

[tex]= 8000 \dfrac{d}{dt}e^{0.07 \ t}[/tex]

[tex]\dfrac{dA}{dt}= 8000 (0.07)e^{0.07 \ t}[/tex]

[tex]\dfrac{dA}{dt}= 560 e^{0.07 \ t}[/tex]

At t = 2 years; the instantaneous rate of change is:

[tex]\dfrac{dA}{dt}|_{t=2}= 560 e^{0.07 \times 2}[/tex]

[tex]\mathtt{\dfrac{dA}{dt}|_{t=2}=644.15}[/tex]

(B) Find the instantaneous rate of change of the amount in the account at the time the amount is equal to $12,000.

Here the amount = 12000

[tex]12000 = (8000)e^{0.07 \ t}[/tex]

[tex]\dfrac{12000 }{8000}= e^{0.07 \ t}[/tex]

[tex]1.5= e^{0.07 \ t}[/tex]

㏑(1.5) = 0.07 t

0.405465 = 0.07 t

t = 0.405465 /0.07

t = 5.79

[tex]\dfrac{dA}{dt}= 560 e^{0.07 \ t}[/tex]

At t = 5.79

[tex]\dfrac{dA}{dt}|_{t = 5.79}= 560 e^{0.07 \times 5.79}[/tex]

[tex]\mathtt{\dfrac{dA}{dt}|_{t = 5.79}= 839.86 }[/tex]
