Answer:

Option A

Step-by-step explanation:

The given function is a linear function therefore rate of change of this function will be the slope of the given line.

Since this line passes through two points ( 0,1 ) and ( 0.5 0 )

the slope of the line = \frac{(y-y')}{(x-x')}

                     slope   = \frac{(1-0)}{(0-0.5)}

                                 = ( -2 )  

Therfore, Option A will be the answer.

Mark borrowed $5,500 at 11.5 percent for five years. What is his monthly payment?
olya-2409 [2.1K]
Use the formula of the present value of an annuity ordinary which is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value 5500
PMT monthly payment?
R interest rate 0.115
K compounded monthly 12
N time 5years
Solve the formula for PMT
PMT=Pv÷ [(1-(1+r/k)^(-kn))÷(r/k)]
PMT=5,500÷((1−(1+0.115÷12)^(
−12×5))÷(0.115÷12))
=120.95

So the answer is C

Hope it helps!

Find the slope of the line that passes through (-33, -27) and (-32, -25).
Snezhnost [94]

Answer: 2.

Step-by-step explanation:

You can find the slope between two points by using the "rise-over-run" method.

This method essentially calculates the slope as the quotient of the vertical span and horizontal span of the two points.

You can find it through this formula:

s = \frac{y2 - y1}{x2 - x1}

To find the slope, use two points, (x1, y1) and (x2 and y2).

For the points given, I will replace those values in the formula with (-33, -27) and (-32, -25).

s = \frac{-27 - (-25)}{-33 - (-32)}\\\\s = \frac{-2}{-1}\\\\s = 2

The slope of the line is 2.

Convert a markup of 15% on selling price to its equivalent markup on cost.
spayn [35]

Answer:

option: D is correct. (  (D) a markup of 15% on selling price is equivalent to a 85% markup on cost ).

Step-by-step explanation:

" Markup is the percentage difference between a product's cost and its selling price "

Since we are asked to Convert a markup of 15% on selling price to its equivalent markup on cost.

As there is a markup of  15% on selling price. Hence the cost of the product would be (100-15)%=85% of the selling price.

<em>Hence, a markup of 15% on selling price is equivalent to a 85% markup on cost.</em>

<em>Hence, option D is true.</em>
