Answer:

C) Izzy

Step-by-step explanation:

Justin typed 90 words in 2 minute:

work

405/9=45 words a minute

45*2=90

Remmy typed 84 words in 2 minute:

work

420/10=42 words a minute

42*2=84

Izzy typed 98 words in 2 minutes:

work

588/12= 49 words a minute

49*2 = 98

I hope this helps :)

Answer:

Step-by-step explanation:

We need to find how many words each of them can type in 2 minutes.

Justin-

Justin can type 135 words in 3 minutes. First, find how many words he can type in 1 minute:

135/3 = 45 words per minute

Then, multiply by 2 to find how many words he can type in 2 minutes:

45 * 2 = 90

90 < 95, so he is eliminated.

Remmy-

Do the same as we did for Justin. Find the number of words she can type in 1 minute:

168/4 = 42

Multiply by 2:

42 * 2 = 84 words per minute

84 < 95, so she is eliminated.

Izzy-

Find the number of words she can type in 1 minute:

147/3 = 49 words per minute

Multiply by 2:

49 * 2 = 98

98 > 95, so she can type a minimum of 95 words every 2 minutes.

1. Evaluate the function f(x)=3x-1 using the domain of -2, 0, 3, and 5. Results are to be shown in a table.

IceJOKER [234]

Answer:

See explanation

Step-by-step explanation:

You are given the function $f(x)=3x-1$

The domain of the function are all possible values of variable x, so you can find f(x) for x=-2, 0, 3, 5:

$f(-2)=3\cdot (-2)-1=-6-1=-7\\ \\f(0)=3\cdot 0-1=0-1=-1\\ \\f(3)=3\cdot 3-1=9-1=8\\ \\f(5)=3\cdot 5-1=15-1=14$

The table is

$\begin{array}{cc}x&f(x)\\-2&-7\\0&-1\\3&8\\5&14\end{array}$

The inverse function $f^{-1}(x)$ has the domain which is the range of the function f(x) (all possible values of f(x)), so the domain of inverse function is {-7,-1,8,14}

Dmitrij [34]

We have to calculate the amount of money Peter will have in his account after 5 years. Formula for the amount after t years with interest compounded continuously : A = P * e^(r t ). We know that r = 0.06; t = 5; e = 2.71 and P = $8,000. A = 8,000 * 2.718^( 0.06 * 5 ) = 8,000 * 2,718^( 0.3 ) = 8,000 * 1.3488158 = 10,798.53. Answer:<span> B. $10,798.53. </span>

PLEASE HELP ME IM BEGGING YOU IT IS EASY Consider the two groups listed below. Which statement describes the sets? (2 points) ho

miskamm [114]

Note that mailing address is unique, but houses are not, meaning that you can't have house A and house B both referencing the same address.

So, in order to have a valid function, any two points on the function cannot have the same x value that lands on different y.

With this property mentioned, it's clear to see that
(house, address) is NOT a function; however, (address, house) is a function, since same x lands on multiple y values is a valid onto function. (a house that have multiple addresses)
