Solve for x in the following figure.

Answers

Answer 1

Answer:

x = 80

Step-by-step explanation:

All angles in a triangle add up to 180 degrees.

First, find the angle J:

60+40 = 100, J = 80 because 100+80= 180 degrees.

Now, the two angles on either side of J should also equal 180 degrees. We know that the inner angle is equal to 80 degrees. Thus, the outside angle must equal 100.

x + 20 = 100

x = 80 degrees.

Use I'Hopital's Rule more than once to rewrite the limit in its final form as lim x --> 0
lim x --> 0 e^x -sinx - 1/ x^4 + 7x^3 + 8x^2

Answers

To compute the limit

[tex]\displaystyle\lim_{x\to0}\frac{e^x-\sin x-1}{x^4+7x^3+8x^2}[/tex]

notice that when x = 0, both the numerator and denominator converge to 0. Apply l'Hopital's rule once gives

[tex]\displaystyle\lim_{x\to0}\frac{e^x-\cos x}{4x^3+21x^2+16x}[/tex]

but again, this returns the indeterminate form 0/0. Applying again gives

[tex]\displaystyle\lim_{x\to0}\frac{e^x+\sin x}{12x^2+42x+16}[/tex]

so that the numerator converges to e⁰ + sin(0) = 1, and the denominator converges to 12•0² + 42•0 + 16 = 16.

So the limit is 1/16.

Step-by-step explanation:

Distribute the 7 to get 273=14n+21

Subtract 21 to get 14n=252

Divide by 14 to get 18

Answer:

N=18

Step-by-step explanation:

Distribute~ 273=14n+21

Minus 21 to both sides~ 273-21=14+21-21

Divide your 14 to get rid of your variable~ 14n/14=252/14

Vineisha earned 22 out of 20 points on her science quiz over the phases of the moon due to an extra credit question. What percent did she earn on the quiz?

Answers

Vineisha earned 110 percent on the science quiz which was about the phases of the moon.

How to calculate the percent earned ?

Vineisha earned 22 out of 20 points on her science quiz over the phases of the moon

The percent earned can be calculated by dividing 20 by 22 and then multiplying the result by 100

22/20 × 100

= 1.1 × 100= 110

Hence the percent she earned on the quiz is 110%

Answers

Answer:

x = 2

Step-by-step explanation:

2x - 3 = 9 - 4x ( add 4x to both sides )

6x - 3 = 9 ( add 3 to both sides )

6x = 12 ( divide both sides by 6 )

x = 2

The measure of {x} in the equation -3 = 9 - 4x is {x} = 3

What is function?

A function is a relation between a dependent and independent variable. We can write the examples of function as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to find the value of {x} for the equation -

- 3 = 9 - 4x

The given equation is -

- 3 = 9 - 4x

We can write that -

- 3 = 9 - 4x

4x = 9 + 3

4x = 12

x = 3

Therefore, the measure of {x} in the equation -3 = 9 - 4x is {x} = 3.

Write the point-slope form of the line that passes through (–7, 8) and has a slope of –5.

Answers

Answer: y = -5x + 20

Step-by-step explanation:

Remember that : y=mx+b

y = (-5)x + b

Now you can plug your coordinates (-7,8) into that equation.

8 = (-5)-7 + b

Solve for b

8 = -12 + b

Add +12 to both sides of your equation:

20 = b

Now, your new equation is:

y = -5x + 20

(x + 10)°. What is the value of x?

Answers

Answer:

x = 35º

Step-by-step explanation:

(x - 5)°+ (3x)º+ (x + 10)° = 180º

5x + 5 = 180º

5x = (180 - 5 )º

5x = (175 )º
