What is 2x116 and 4x17

Answers

2* 116
= 2*(100+16)
= 2*100+ 2*16 ( distributive property)
= 200+ 32
= 232

The final answer is 232~

4*17
= 4*(10+7)
= 4*10+ 4*7 (distributive property)
= 40+ 28
= 68

The final answer is 68~

For 2times116 =232 and for 17times4=68

Using complete sentences, explain the key features of the graph of the sine function.

Answers

The trigonometric functions have features that are worthy of note. Among these features are the period and amplitude. The graph of f(x)=sin x repeats itself along the x-axis by a certain distance. This distance is called the period. For the sine function, the period is 2pi radians. It can also be observed that the graph goes up and then down by a certain distance. This distance is called the amplitude. For the curve of f(x)=sin x, the amplitude is 1.

The area of a bathroom floor measures 2 yards by 3 yards and each custom tile that makes up the flooring is 1 1/2 square feet. How many tiles are needed to cover the floor?

Answers

The dimensions of the bathroom floor is given as 2 yards by 3 yards.
Then
The area of the bathroom floor in question = (2 * 3) square yards
   = 6 square yards
We already know that
1 square yard = 9 square feet
So
The area of the bathroom floor in question = (6 * 9) square feet
   = 54 square feet
Area covered by each custom tiles = 11/2 square feet
Then
Number of tiles required to cover the bathroom floor = 54/(11/2)
   = (54 * 2)/11
   = 108/11
   = 9.81
So the number of tiles required to cover the bathroom flooring is 10. Since fraction of tiles cannot be bought, so 10 tiles are required.

Find the measures of the labeled angles. HELP ASAP PLEASE

Answers

The measures of the labelled angles that are vertically opposite to each other are:

x + 87 = 116 degrees

4x = 116 degrees

(x + 87) and 4x are vertical angles directly opposite each other.

According to the vertical angles theorem, (x + 87) and 4x are congruent.

Therefore, we will have:

(x + 87) = 4x

Solve to find the value of x

x + 87 = 4x

Subtract x from both sides

x + 87 - x = 4x - x

87 = 3x

Divide both sides by 3

29 = x

x = 29

Find the labelled angles by plugging in the value of x

x + 87 = 29 + 87 = 116 degrees

4x = 4(29) = 116 degrees

Therefore, the measures of the labelled angles that are vertically opposite to each other are:

x + 87 = 116 degrees

4x = 116 degrees

(x + 87)° = 116°

We can see that the angle of (x + 87)° is directly across from the angle of 4x°. This shows that they are equal. We can take the two terms and make an equation.

—> (x + 87) = 4x

After solving for the value of x, we get a value of 29.

Now that we know x, let's substitute it into (x + 87).

(x + 87) becomes (29 + 87), which is equal to 116°.

To check,we can substitute 29 into the other angle of 4x as well, since the two angles are equal.

4x becomes 4(29), which is also equal to 116°.
