Answer:

Step-by-step explanation:

You can eliminate answer A because when X=1, Y must equal 33.75 not 33.

You can eliminate answer B because when X=0, Y must equal 0 not 1.

You can eliminate answer D because this answer has the X and Y coordinates reversed. When X=1, Y= 33.75. When X=4, Y=135, etc.

Charlie deposits $250 on the last day of each month into an account that earns 6% annual interest compounded monthly. Complete t

Ierofanga [76]

Answer:

A=$265.42

Step-by-step explanation:

The formula to apply here is;

$A=P(1+\frac{r}{n} )^{nt}$

where;

A=amount at the end

P=principal amount=$250

r=rate of interest=0.06%

n=number of compounding per year=12

t=total number of years=1

$A=250(1+\frac{0.06}{12} )^{12*1} \\\\A=250(1.005)^{12}\\ \\\\A=265.42$

PLEASE HELP

Gala2k [10]

First we have to determine a linear equation. We will take two points (0,900) and (1,850):
y=mx+b
900=m*0+b, b=900
850=m*1+900
m=-50
Linear equation is:
y=-50x+900
Part A: y-interception is y=900 or(0,900).
It means that a car has to travel a distance of 900 miles to reach a final destination.
Part B:Average rate of change: $\frac{y2-y1}{x2-x1} = \frac{750-850}{3-1}= \frac{-100}{2}$ =-50. It represents how many miles per one hour changes the distance from a destination.
Part C: Domain of this function if the car traveled the same rate until it reached its destination:
0=-50x+900
50x=900
x=900/50=18
Domain: x∈ [0, 18].

A machine used to make badges costs $120. It costs $5 to make each badge. Write a function to show the total cost f(n) of making

vladimir1956 [14]

First, I find it helpful to write the function myself.

There is a set fee of $120, and $5 per n badges.

120 + 5n

This is a basic model. Now we can see if any match.

f(n) = 5n + 120 matches.

Let me know if you found any errors.

Prove:

Levart [38]

Given the statement, "If $n^2$ is odd, then $n$ is odd," its contrapositive claims that, "If $n$ is not odd, then $n^2$ is not odd."

So assume $n$ is not odd, i.e. $n$ is even. This means there is an integer $k$ for which $n=2k$ . Squaring this gives $n^2=(2k)^2=4k^2$ .

Well, we can write $4k^2=2(2k^2)$ , and $2k^2$ is just another integer, which means $4k^2=(2k)^2=n^2$ must be even.
