During an experiment, the temperature of a liquid, in degrees Celsius, is given by the function t(m)= -0.2m+6, where m is the number of minutes since the experiment began.

Which graph correctly shows this function?

Answer:3 8 10

Step-by-step explanation:

P(A) =Probability of heads

P(B) = Probability of tails

P(B)= 1 - P(A) = 1 - 58 = 42%

The events are independent, so, let's assume that we flip the coin and the first two results are heads, so:

P(A) =0.58

Now, let's assume the last two results are tails so:

P(B) = 0.42

The equation of the line is given as y = -2x + 22. This means that when x  is equal to zero, y = 22. M also shows how steep the line is, being the gradient.

In order to arrive at a logical solution, we must assume the value of the slope as this is not given.

Assuming the slope of the line is -2, we thus can say:

The equation of a line that passes through a point (x₁,y₁) and a slope m is given by

(y - y1) = m (x - x1)

Recall that the slope, m = -2

While
Point (x1, y1) = (7, 8)

Hence, the equation of the line is:

y-8 = (-2) (x-7)

y-8 = -2x + 14

y = -2x+ 14 + 8

Hence,

y = -2x + 22

Thus, the equation of the line is:
y = -2x + 22

1. Tha rate of return is 11.12%

2. The investor will not be happy in case the market interest rates fall

n is NPER 5 (called back in 5yrs)

Coupon payment / PMT = 1000 * 10% = 100,

Purchase price PV (PV is entered as a negative value) -1000

Called for value is FV Call premium is 7% hence FV = 107% * 1000 = 1070

You can use the RATE function in excel

Rate(nper, PMT, PV,FV, Type)

RATE(5,100,-1000,1070)

= 11.12%

The investor was promised a fixed return rate of 10%, but since the bond was called after 5 years, the actual return was 11.12%, so the investor had good reason to be pleased.

In the event that market interest rates decline, the investor will not be pleased because, had the bond not been called, he would have continued to receive his fixed 10% coupon payments of $100 per year.

An inequality that represents all possible combinations of x shirts and y pants is (12.99x + 15.99y) ≤ 125.

Given:

Cost of each shirt = $12.99

Cost of each pant = $15.99

Let's assume the number of shirts is x and the number of pants is y.

Total cost of x shirts = $12.99x

Total cost of y pants = $15.99y

Total cost = $(12.99x+15.99y).

Now, she does not want to spend more than $125 which means she can spend equal to or less than 125 dollars.

First, multiply all points by 2 (this is the first transformation)

A => A'(-4,-8)

B => B'(0,-2)

C => C'(4,-8)

Next, translate the previous points 6 units upward (which means add 6 units to each y-coordinate).

A' => X(-4,-2)

Given two equations

[tex]4x-2y=8[/tex]

[tex]3x+y=2[/tex]

Since there are two equations and two unknowns we can solve the equations by arithmetical methods.

Initially multiply second equation by 2 and add it it to first equation.

[tex]3x+2y=2[/tex] × 2

[tex]6x+2y=4[/tex]

Now adding this to equation 1

[tex]4x-2y=8 + 6x+2y=4[/tex]

[tex]10x=12[/tex]

[tex]x=1.2[/tex]

To get y value substitute x value in any of the equation

The revenue is at a maximum after x = 9

The maximum is $ 261

9 hearing aids are produced and sold.

The revenue, R(x), of producing and selling 'x' Awesome Hearing Aids is modeled by the function,

R(x) = -3x² + 56x

We need to find the number of hearing aids produced and sold in order to maximize the revenue.

We use the differentiation method to find the maximum of the function R(x).

Differentiate R(x) with respect to x and equate it with 0,

R'(x) = -6x + 56

Then, -6x + 56 = 0

⇒ 6x = 56

⇒ x = 56/6 = 9.33 ≈ 9  [since x is the number of hearing aids]

Now we find the second derivative of R(x) at x = 9.

R''(x) = -6

⇒ R''(9) = -6 < 0

Since R''(9) < 0, the revenue R(x) is maximum at x = 9.

So the maximum revenue is obtained after x = 9.

Therefore maximum revenue = R(9) = -3 x 9²+56 x 9 = $ 261
