24 times 4 tons 2 pounds
Iteru [2.4K]
Ayy, so your question is kinda weirdly worded. But I think your asking what is 24 multiplied by 4 tons and 2 pounds.

Well, 2 pounds is equal to 0.00090718 tons.
There is a converter here: https://www.bing.com/search?q=pounds+to+tons&qs=AS&pq=pounds+to+tons&sc=8-14&sp=1&cvid=7BC591B75A8B4......

But now we have 0.00090718 tons as well as 4 tons. Add those together and you get 4.00090718. Now, multiply this by 24. You get: 96.02177232.

The initial cost for Travis and his band to record their first CD was $1500. Each CD will cost $4 to produce. If they sell their
a_sh-v [17]
C=1500+4x where x is cds, C is cost
R=10x where R is revenue
then, P=R-C
P=10x-1500-4x
P=6x-1500
set P=0
1500=6x
x=250
check, C=1500+4*250, R=10*250
C=250, R=250
They need to sell 250 cds before they make profit

PLZ HELP, 20 pts and brainliest awarded, plz ASAP!!!!!!<br><br> see image below
Amiraneli [1.4K]

Answer:

Option B

Step-by-step explanation:

we have

f(x)=x^{3}-x^{2}-9x+9

we know that

<u>The vertical line test </u>is a visual way to determine if a curve is a function or not. A function can only have one value of y for each unique value of x

In this problem

The given function  passes the vertical line test

therefore

f(x) is a function

<u>The Horizontal Line Test</u>  is a test use to determine if a function is one-to-one

If a horizontal line intersects a function's graph more than once, then the function is not one-to-one.

In this problem

The given function fails the horizontal line test

because for f(x)=0 x=-3, x=-1, x=3

therefore

It is no a one-to-one function
