Answer:

square root of 133

Step-by-step explanation

Pick a number between 11 and 12

Square the number (To the 2nd power)

Then add like 1 or something so the number is still between 11 and 12

Then use a calculator and do the square root of the number to check if it is still between 11 and 12

The circumference of a circle with radius $r$ is $2\pi r$ . If the length of the radius is tripled, then the circumference becomes $2\pi(3r)=3\cdot2\pi r$ , which is just 3 times the original circle's circumference.

Which is the value of this expression when a=-2 and b=-3

Lerok [7]

Answer:

$\frac{729}{64}$

Step-by-step explanation:

The given expression is

$(\frac{3a^{-3}b^{2} }{2a^{-1} b^{0} } )^{2}$

Where $a=-2$ and $b=-3$ .

When we say "evaluate the expression" refers to replacing the given values in the expression. Then, we solve each power in the numerator and denominator. After that, we solve each product in the fraction. At the end, we apply the square power. As follows

$(\frac{3a^{-3}b^{2} }{2a^{-1} b^{0} } )^{2}=(\frac{3(-2)^{-3}(-3)^{2} }{2(-2)^{-1} (-3)^{0} } )^{2}=(\frac{3(\frac{1}{-8})(9)}{2(\frac{1}{-2} (1))} )^{2} =(\frac{-\frac{27}{8} }{-1} )^{2} =\frac{27^{2} }{8^{2} } =\frac{729}{64}$

Find the y intercept. I already found the slope is 9.

jeka57 [31]

The slope-intercept form: y = mx + b

We have the slope m = 9, therefore: y = 9x + b.

Next. We have the table:

x | -5 | -2 | 1 | 3 | 4 |

y |-46|-19| 8 |26|35|

(1, 8) → x = 1, y = 8

substitute the values of x and y to the equation:

8 = 9(1) + b

8 = 9 + b |-9

b = -1

Answer: y = 9x - 1 → y-intercept is -1.
