Each week Quentin earns $30. If he saves this money, create a graph that shows the total amount of money Quentin has saved from

week 1 through week 8. Write an equation that represents the relationship between the number of weeks that Quentin has saved his money, w, and the total amount of money in dollars that he has saved, s. Then, name the independent and dependent variables. Write a sentence that shows this relationship.

Answer: s = 30w

graph attached

Step-by-step explanation:

Quentin earns $30/week

w = weeks

s = saved money

s = 30w

s depends on w. Each week he adds $30 to his total amount, so to know how much money he has in the end of each week, we need to multiply 30 by the number of the week.

independent variable = w

dependent variable = s

Answer:

y = -4

x = 3

Step-by-step explanation:

Let's first explain when x = 0

Find where x = 0 on the graph. We are finding what the y-value would be. Trace down the y-axis along the vertical line x = 0. Where does the line intersect the y-axis when x = 0? The answer would be -4

The y-intercept is -4, and the x-value for this is 0, of course. So the correct answer for when x = 0 would be y = -4.

Next, we are told to find x when y = -2. Find where y = -2. Now, staying at y = -2, go horizontally along the x-axis at y = -2 until you reach the line. Boom! You should have connected up with the line at around x = 3. Therefore, when y = -2, x = 3

95i is a root of f(x)=x^2 +9025. find the other roots of f(x)
Alex_Xolod [135]

Answer:

Other root is -95i

Step-by-step explanation:

Here, Nature of roots of f(x) is imaginary roots.

Therefore, Roots are conjugate of each other.

Conjugate of x + yi is x - yi.

we get conjugate of 95i as -95i

Verification shows....

(x-95)(x+95i)=0

{x }^{2}  -  {95}^{2}  {i}^{2}  = 0 \\  {x }^{2}   + {95}^{2} = 0  \\ {x }^{2}   + 9025= 0   \\ f(x) = 0

this, roots are -95i and 95i

McGwire Aerospace expects to have net cash flow of $12 million. The company forecasts that its operating costs excluding depreci
slava [35]

Based on the net cash flow, the depreciation and amortization, and the tax rate, the expected sales of McGwire Aerospace is $66.67 million.

<h3>What are the expected sales?</h3>

First, find the net income:

= Net cash flow - depreciation and amortization

= 12 - 5

= 7 million

Given this net income, the sales are:

Net income = ( Sales - (Sales x 75%) - 5) x (1 - 40%)

7 / 0.60 = 0.25x - 5

11.67 = 0.25x - 5

0.25x = 16.67

x = 66.67 million

In conclusion, the expected sales are $66.67 million.
