A computer manufacturer built a new facility for assembling computers. There were construction and new equipment costs. The company paid for these costs and made combined profits of $40 million after 4 years, while profits increased $30 million per year. Select the correct graph of this function. (2 points)A)There is a graph of a line that has a y intercept that is approximately $80 million and passes through the point of approximately x equals 2 years and y equals $140 million.B)There is a graph of a line that has a y intercept that is approximately negative $80 million and an x intercept that is approximately 2.7 years.C)There is a graph of a line that has a y intercept that is approximately negative $45 million and an x intercept that is approximately 2 years.D)There is a graph of a line that has a y intercept that is approximately negative $45 million and an x intercept that is approximately 0.6 years.

A line passes through the points ( - 9, - 24) and (8, – 9).Calculate the slope of the line. Write your answer as a fraction.
(If the slope is undefined, enter "DNE")

Answers

Answer:

15 / 17

Step-by-step explanation:

slope = (y2 - y1) / (x2 - x1)

  = (-9 + 24) / (8 + 9)

  = 15 / 17

Answer:

you will see it

Step-by-step explanation:

Look for the y-intercept where the graph crosses the y-axis.

Look for the x-intercept where the graph crosses the x-axis.

Look for the zeros of the linear function where the y-value is zero.

In a right triangle, Angle A and B are acute. If tan B= 2, what is cos B? Round to three decimal places.Show work plzzz!!!

Answers

The value of cosB ≅ 0.447 to three decimal places.

Since angle A and angle B are acute and tanB = 2, we find cosB from the trigonometric identity

tan²B + 1 = sec²B

Find SecB

So, substituting the value of tanB into the equation, we have

tan²B + 1 = sec²B

2² + 1 = sec²B

4 + 1 = sec²B

5 = sec²B

Taking square root of both sides, we have

√sec²B = ±√5

secB = ±√5

Find CosB

Since secB = 1/cosB, we have that

1/cosB = ±√5

⇒cosB = ±1/√5

Since B is acute, cosB will be positive.

So, cosB = 1/√5

cosB = 1/2.2361

cosB = 0.4472

cosB ≅ 0.447 to three decimal places.

So, the value of cosB ≅ 0.447 to three decimal places.

The taxi driver charges $3.50 just to get in the cab and then $2.50 per mile. If Lisa travels m miles, which equationtells Lisa how much she will have to pay for her taxi ride, r?
A r = 2.5 +3.5
B = 3.5m + 2.5
r= 2.5m + 3.5
Dr= 2.5m - 3.5

Answers

Answer:r=2.5m+3.5

Step-by-step explanation:
the answer is 2.5m + 3.5 because we don't know how many miles the taxi driver drove
