Step-by-step explanation:

Cost of meal = [tex]64.75[/tex]

Cost of meal after discount of [tex]15\%[/tex]

[tex]64.75-64.75\times 0.15[/tex]

[tex]=64.75(1-0.15)[/tex]

Decide whether −3/12 terminates or repeats when expressed as a decimal

Answers

It terminates. When you put this into your calculator, you get -0.25. It terminates, or ends, after the 5.

A repeating decimal is like this...
0.2837268765108375682.... you get the idea. It could also be represented at with a bar above the last digit(s) as that repeats forever. But the answer is terminating. Good luck!

1 - Find the values of x for which the combined function h(x) = f(x)/g(x) is undefined if f(x) = 5x + 1 and g(x) = x^2 - 9.

x = ±3
x = 3
x = -3
x = ±9

2 - Find the function h(x) = f(x) - g(x) if f(x) = 3^x and g(x) = 3^2x - 3^x.

h( x) = 0
h( x) = -3 ^2x
h( x) = 3 ^x(2 - 3 ^x)
h( x) = 2(3 ^2x)

Answers

Answer:

Part 1)

A

Part 2)

C

Step-by-step explanation:

1)

We are given:

[tex]f(x)=5x+1\text{ and } g(x)=x^2-9[/tex]

And that:

[tex]h(x)=f(x)/g(x)[/tex]

And we want to now for which values of x is h(x) undefined.

So, by substitution:

[tex]\displaystyle h(x)=\frac{5x+1}{x^2-9}[/tex]

Remember that for rational functions, the function will be undefined if and only if the denominator is 0.

This is because we cannot divide by 0.

So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:

[tex]x^2-9=0[/tex]

Add 9 to both sides:

[tex]x^2=9[/tex]

Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:

[tex]x=\pm 3[/tex]

So, h(x) is undefined for ±3.

Our answer is A.

2)

We are given:

[tex]f(x)=3^x\text{ and } g(x)=3^{2x}-3^x[/tex]

And we want to find:

[tex]h(x)\text{ if } h(x)=f(x)-g(x)[/tex]

So:

[tex]h(x)=3^x-(3^{2x}-3^x)[/tex]

Distribute:

[tex]h(x)=3^x-3^{2x}+3^x[/tex]

Combine like terms:

[tex]h(x)=2(3^x)-3^{2x}[/tex]

Rewrite:

[tex]h(x)=2(3^x)-(3^x)(3^x)[/tex]

Factor out:

[tex]h(x)=3^x(2-3^x)[/tex]

So, our answer is C.

Chris works at a jewelry store, and he earns 4% commission on all sales that he makes. If Chris's jewelry sales total $1,370, how much will he earn in commission?

Answers

Answer:

[tex]\boxed {\boxed {\sf \$54.80}}[/tex]

Step-by-step explanation:

Chris earns the commission on the jewelery sales. To calculate what he earned, multiply the commission rate and his sales.

[tex]commission= commission \ rate * sales[/tex]

His rate is 4% and his sales are $1,370

[tex]commission= 4\% * \$1370[/tex]

Convert the percent to a decimal. Divide by 100 or move the decimal two spots to the left.

4/100= 0.04 4.0   -->   0.4   -->   0.04

[tex]commission= 0.04* $1370[/tex]

[tex]commission = \$ 54.8[/tex]

Chris's commission is $54.80

A 2-bedroom apartment that rents for $520 a month is $40 less than twice the cost of a 1-bedroom apartment. What is the monthly rent of a 1-bedroom apartment?​

Answers

Answer:monthly rent of a 1-bedroom apartment= $280

Step-by-step explanation:

Let the  cost of 1 bed room apartment = x

And the cost of two bedroom apartment= 2x-40

Since the cost of of two bedroom apartment = $520  

Then the cost of one bed room part will be expressed as

520= 2x- 40

520+40 = 2x

560= 2x

x= 560/ 2

x= 280

Therefore the  cost of 1 bed room apartment = x= $280
