a cylindrical well has a tedious of 10 feet and a height of 15 feet. What volume of water will it take to fill the well

1 answer:

5 0

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=10\\ h=15 \end{cases}\implies V=\pi (10)^2(15)\implies V=1500\pi$

What’s the inverse of 4x + 12

stiks02 [169]

Answer:

1/4x -3

Step-by-step explanation:

To find the inverse of a function, exchange x and y and then solve for y

y =4x+12

Exchange x and y

x = 4y+12

Solve for y

Subtract 12 from each side

x-12 = 4y+12-12

x-12 = 4y

Divide by 4

(x-12)/4 = 4y/4

The inverse is

1/4x -3

Maria scored 72, 97, and 82 on her first three math tests. She wants to have a mean score of 82 for the quarter. How many points

Rom4ik [11]

Answer:

She needs 77 on her last test to earn an 82 for the quarter.

Step-by-step explanation:

Maria scored 72, 97, and 82 on her first three math tests.

She wants to have a mean score of 82 for the quarter.

Let us assume that she must score x on her last test to earn an 82 for the quarter.

So the average score will be,

$=\dfrac{72+97+82+x}{4}$

But the average score is given as 82, so

$\Rightarrow \dfrac{72+97+82+x}{4}=82$

$\Rightarrow 72+97+82+x=82\times 4$

$\Rightarrow 72+97+82+x=328$

$\Rightarrow x=328-72-97-82$

$\Rightarrow x=77$

How would you solve this?

siniylev [52]

Answer:

Step-by-step explanation:

hello :

(x-4)²(x+3)² = -1

means : ((x-4)(x+3))² = - 1 this equation has no solutions in R

because for all x in R : ((x-4)(x+3))² ≥ 0

What’s the domain of this graph??

charle [14.2K]

the domain of the graph is where on the x axis there is a graph.

here the domain, x, is less than or equal to 6, isnce it goes down on the negative side

the arrow means the line goes on forever, so

x<=6

(x is less than or equal to 6)
