Answer:

<h3>\boxed{ \bold{ \huge{ \boxed{ \sf{ {12.56 \:  {mm}^{2} }}}}}}</h3>

Step-by-step explanation:

Given,

Radius ( r ) = 2 mm

pi ( π ) = 3.14

<u>Finding </u><u>the </u><u>area </u><u>of </u><u>circle </u><u>having </u><u>radius </u><u>of </u><u>2</u><u> </u><u>mm</u>

Area of circle \sf{ = \pi \:  {r}^{2} }

plug the values

⇒\sf{3.14 \times  {2}^{2} }

Evaluate the power

⇒\sf{3.14  \times 4}

Multiply the numbers

⇒\sf{12.56 \:  {mm}^{2} }

Hope I helped!

Best regards!!

Genevieve wants to verify that }(5x-20)-(4x-8) is equivalent to x. Which procedure can Genevieve follow to determine if
Gnom [1K]

They aren't equivalent

<h2>Explanation:</h2>

In order to determine whether the expression:

(5x-20)-(4x-8)

is equivalent to:

x

Genevieve needs to follow these steps:

Step 1. Get rid parentheses

5x-20-4x+8

Step 2. Combine like terms

5x-4x-20+8

Step 3. Solve

x-12

So:

x\neq x-12

Therefore, these two expressions aren't equivalent.

Does anybody have any tips for calculating slopes in Algebra 1???
I am Lyosha [343]

Answer:

The equations are really hard, so if you can find a slope interpreter or something that might be helpful.

I find it easier to just count the up and across.

Find the value of k such that lim--&gt;4 (x^2+x-k)/(x-4) exists
7nadin3 [17]

Answer:

k=20

Step-by-step explanation:

when x approaches 4, the denominator x-4 approaches 0

if the denominator is 0, it means that this is invalid

if the function is a number over 0 when x=4, it represents a vertical asymptote, which means no limit

so the only way possible to let there be a limit is to let the function be 0/0 when we plug in x=4

so x^2 + x - k = 0 when x = 4

4^2 + 4 - k = 0 ==> 20 - k = 0 ==> k = 20
