Answer:

See below.

Step-by-step explanation:

sin x / x.

You can prove this by L'Hopitals Rule.

If x = 0 then the function = 0/0 so the above rule is applicable here.

Differentiating top and bottom we get cos x / 1  = cos x.

Limit x --> 0 of cos x = 1 so it is proved.

If mEAF=2x+4 and mGAF=x+11,then solve for the value of x algebraically use this value of x to find mEAF
jonny [76]

Vertical angles are angles that meet at the point. The angles EAF measures 18 degrees

<h3>What are Vertical angles?</h3>

Vertical angles are angles that meet at the point where two lines intersects and facing each other.

These angles are always equal to each other. Given the vertical angles shown below:

mEAF=2x+4 and;

mGAF=x+11

Equate both expressions to have:

2x + 4 = x + 11

Collect the like terms

2x-x = 11 - 4

x = 7

Determine the measure of m<EAF

m<EAF = 2x + 4

m<EAF = 2(7) + 4

m<EAF = 18 degrees

Hence the measure of angles EAF is 18 degrees

Tell whether x and y show direct variation. Explain your reasoning.
Alex Ar [27]

Answer: I may not be correct

This is direct variation. If you move the x to the other side of the equation, it will become:

y = x

Direct variation is when y is equal to x times a constant. In this example, y is equal to 1 * x.

Mary spent $45 at the mall. She bought lunch for $9. She bought 3 shirts at
oee [108]

Answer:

x = 12

Step-by-step explanation:

If Mary spent $45 altogether,

then she bought lunch for $9

so our equation now is

$45 = $9 + 3x

It is 3x because he bought 3 shirts and we used x because we didnt

now how much the price of those shirts were

$45 = $9 +3x

$45 - $9 = 3x

$45 - $9 = $36

$36 = 3x

$36 / 3 = 12

x = 12

(7-2)² - 5 / 5 I dont get the exponent part can someone help me with whole problem
ruslelena [56]

(7-2)² - 5/5

Do the math in the parentheses first.

7 - 2 = 5

Now the equation should read

(5)² - 5/5     or just       5² - 5/5

Do the exponent(s).

5² = 25

25 - 5/5

Do the division.

5/5 = 1

25 - 1 = 24

Therefore, according to our equation, the answer is 24.

I hope this answered your question.
