Hello!

A(r) is a function. It takes a value of r, and from that calculates the value A. In this case, it takes the value of a radius, and depending on what that value is, it calculates the area.

A(3) would therefore represent the area based off of a radius of 3.

Hope this helps!

Rachel earned \$34$34 in 44 hours at her job today. She wants to know how much she could earn (e)(e) tomorrow if she works 1010

kari74 [83]

Answer:

Rachel will earn $85 in 10 hours.

Step-by-step explanation:

Rachel earned $34 in 4 hours at her job today.

Suppose, she will earn $x$ dollar in 10 hours tomorrow.

So, according to ratio of 'dollar' and 'hours', the equation will be.....

$\frac{34}{4}=\frac{x}{10}$

After cross multiplying, we will get.....

$4x= 34*10\\ \\ 4x= 340\\ \\ x=\frac{340}{4}=85$

Thus, Rachel will earn $85 in 10 hours.

algol13

Answer:

A.58.81

Step-by-step explanation:

x = number of parties attended

y = number of text messages sent

The residual is the difference between the actual number of text messages sent (200) and the number of texts predicted by the regression model:

$y=64.96+25.41x\\y=64.96+25.41*3\\y=141.19$

The residual is:

$R=200 - 141.19\\R=58.81$

The answer is alternative A.58.81

Please help!! what are the x-intercepts of this equation.

padilas [110]

The x intercepts are -2 and 5. First, you factor the equation and get (2x+4)(2x-10), then solve for the x's. If you have more problems like this, there's a great online calculator that can help with graphing. www.symbolab.com. It tells you the intercepts if you plug in the equations. Hope this helps!
