Answers

C.12 anyways sooo your welcome

The required reference angle of angle 192 is 12. OPtion C is correct.

Given that,
An angle of 192°
Reference angle to be determined.

What is the angle?

The angle can be defined as the one line inclined over another line.
Angel over angle is of 360° and angle over line is 180°

What is simplification?

The function in mathematics to operate and diagnose the function to make the function simple or more coherent is called simplifying and the process is called simplification.

Since in the question, An angle is given of 192° its corresponding and relatable angle is to be determined.

Here, a standard measure of an angle is 180, So let the reference angle b x, for reference angle the angle must be more or less than 180. So,

x = 192 - 180
x = 12

Thus, the required reference angle of angle 192 is 12. Option C is correct.

- 2x and 70 are equal, because they are vertical angles.

- 110 and 3x + 5 are equal, becasue they are vertical angles.

- so, the answer would be A.

-- this is because vertical angles are not supplementary so would not be equal to 180°

Answers

Answer:
This question is not possible unless the plus sign is actually a minus sign.

Explanation:
First we need to find the LCM, lowest common multiple , for the faction which is 6. Because 3x2 is 6 and 6x1 is 6. So since we mutiply the bottom of the faction 2/3, we need to muitiply the 2 too, which is 6. But....
6 plus 3 or anyone of your option listed wouldn’t be equaled to 1.
So that’s why I don’t think this question is possible to answer.
But... if that sign was a negative the answer would be 5 because 6-5 is 1.

Written as a simplified polynomial in standard form, what is the result when ( x + 2 ) 2 (x+2) 2 is subtracted from 7 x − 4 7x−4?

Answers

Answer:

-x²+3x-8

Step-by-step explanation:

Given polynomials are :

f(x) = (x+2)²

p(x) = 7x−4

We need to find a simplified polynomial when f(x) is subtracted from p(x) i.e.

p(x) - f(x) = 7x−4 - (x+2)²

We know that, (a+b)² = a²+b²+2ab

So,

p(x) - f(x) = 7x−4 -(x²+2²+2(x)(2))

= 7x−4 -(x²+4+4x)

= 7x−4-x²-4-4x

= -x²+3x-8

Hence, the result will be -x²+3x-8.

If a perfect square has a side length of x+2 and a perimeter of 44cm what is the value of x?

Answers

Answer:

The value of x is 9.

Step-by-step explanation:

Given that:

Side length of square = x+2

Perimeter of square = 44 cm

As all sides of a square are equal, therefore,

Perimeter of square = 4s

Putting all the values,

44 = 4(x+2)

44 = 4x+8

44-8 = 4x

36 = 4x

4x = 36

Dividing both sides by 4

[tex]\frac{4x}{4}=\frac{36}{4}\\x=9[/tex]

Hence,

The value of x is 9.

The cost of renting a truck is $40. An additional $0.79 is charged for each mile, m, the truck is driven. Which expression can be used to determine the total cost, in dollars, of renting a truck? (EE.2) *

Answers

Answer:

c = 40 + 0.79m

Step-by-step explanation:

The base cost is $40.

So we have:

c = 40

Then, since an additional $0.79 is charged for every mile driven, we add:

+ 0.79m

So then our equation is:

c = 40 + 0.79m

where c = total cost

and m = number of miles driven

sin(2*36.86989765) and get .96 or 24/25

7/25

Step-by-step explanation:

Start by solving for P

sinP=3/5

take the arcsin or sin^-1 and get

p=36.86989765

Then multiply by 2 and take the sin and get

sin(2*36.86989765) and get .96 or 24/25

Then take cos(2*36.86989765)=.28 or 7/25

Answer:

Steps below

Step-by-step explanation:

sin P = 3/5

cos p = √1 - sin² P = 4/5

sin 2P = 2 * sin P * cos P = 2 * 3/5 * 4/5 = 24/25

cos 2P = cos² P - sin² P = 16/25 - 9/25 = 7/25

Answers

Answer:

97.94 is 83% of 118

Step-by-step explanation:

Let the missing number be x

97.94=83% of x

I.e, 97.94=83/100 × x

97.94=83x/100

Cross multipy 97.94/1=83x/100

We have, 97.94 × 100 = 83x × 1

9794=83x

Divide both sides by 83 to make x the subject of the formula.

9794/83=83x/83

If the area of a rectangle with length (4x) is 4x2 + 12x, find the width.​

Answers

Answer:

The width of a rectangle is: w = x+3

Step-by-step explanation:

Given

The length of rectangle = l = 4x

The area of rectangle = A = 4x² + 12x

To determine

The width of rectangle = w = ?

We know that the formula of the area of the rectangle is

[tex]A = wl[/tex]

substitute A = 4x² + 12x and l = 4x in the equation to determine the width w of the rectangle

4x² + 12x = w×4x

w = [4x² + 12x] / [4x]

Factor 4x² + 12x:   4x(x+3)

w = [ 4x(x+3) ] /  [4x]

w = x+3

Therefore, the width of a rectangle is: w = x+3
