Answer 1

Answer:

36

Step-by-step explanation:

First of all, the area of a circle is always pi(r)^2, which we can then substitute values. We will get pi(10)^2, and once we simplify that, we get 100pi as the area. Since we know that the area of the shaded sector is 10 pi, we can divide 10pi by 100pi to get 1/10. 1/10 is the area of the shaded sector compared to the area of the whole circle. Multiply 1/10 by the angle measure of a circle, which is 360, to get 36 degrees.

Answers

Answer:

[tex]\huge\boxed{\sf \frac{34}{9}\ \ OR \ \ 3\frac{7}{9} }[/tex]

Step-by-step explanation:

Let

x = 3.777.......                (1)

Then

10x = 37.777.....             (2)

Subtracting (1) from (2)

10x - x = 37.7777..... - 3.77777.......

9x = 34

Dividing both sides by 9

x = 34 / 9

x = [tex]3 \ \frac{7}{9}[/tex]

PLEASE HELP I HAVE 30 POINTS Part A: If (6^2)^x = 1, what is the value of x? Explain your answer. (5 points) Part B: If (6^0)^x = 1, what are the possible values of x? Explain your answer. (5 points)

Answers

Answer:

Part A: 0

Part B: All real numbers

Step-by-step explanation:

Part A:

We have:

[tex](6^2)^x=1[/tex]

First, let's evaluate the square:

[tex]36^x=1[/tex]

Now, what to the xth power will equal 1?

Remember the fact that anything (except for 0) to the zeroth power is 1.

Therefore, our x is 0:

[tex]36^0=1[/tex]

Part B:

We have:

[tex](6^0)^x=1[/tex]

Like mentioned previously, anything to the zeroth power is 1. Thus:

[tex]1^x=1[/tex]

Now, 1 is a special base because 1 to any (real) power is still going to be 1. For example:

[tex]1^0=1,1^1=1,1^{999},\text{ and } 1^{\pi}=1[/tex]

Therefore, our values of x is all real numbers.

Find the width and height of a newer 65" television screen with an aspect
ratio of 16:9.

Answers

Answer:

see below

Step-by-step explanation:

65 inches is the diameter  of the screen

We have a right triangle for a tv with the side length of 16x and 9x

Using the Pythagorean theorem

a^2 +b^2 = c^2

(16x)^2 + (9x)^2 = 65^2

256x^2+ 81x^2 = 4225

Combine like terms

337x^2 = 4225

Divide each side by 337

x^2 =4225/37

Take the square root of each side

x =65sqrt(337)/337

x =3.54077562

The width is 16 times this

width =56.65240991

height is 9 times this

height = 31.86698058

. A basketball coach is interested in measuring a player’s vertical jumping ability. While standing
and reaching up, the player’s hand reaches the 4-in. mark on the scale. When jumping, the player
can reach the 19-in. mark. What is the player’s vertical jumping ability?

Answers

Answer:

The player's vertical jump ability is 15 inches

Step-by-step explanation:

The mark on the scale which the player's hand can reach while standing = 4-in which is the standing reach

The mark on the scale the player's hand can reach when jumping = 19-in

Therefore, the player's vertical jumping ability is given as the difference between the height the players hand can reach when jumping and the height which the player's hand can when standing,

Which gives;

The player's vertical jump ability = 19 inches - 4 inches = 15 inches

The player's vertical jump ability = 15 inches.

F(x)=3x-2
Simplify F(2x)-F(x+2)​

Answers

Answer:

3x - 6

Step-by-step explanation:

To evaluate f(2x) and f(x + 2) substitute x = 2x and x = x + 2 into f(x)

f(2x) = 3(2x) - 2 = 6x - 2

f(x + 2) = 3(x + 2) - 2 = 3x + 6 - 2 = 3x + 4

Thus

f(2x) - f(x + 2)

= 6x - 2 - (3x + 4)

= 6x - 2 - 3x - 4

= 3x - 6

Answer:

Answer: Option B.

Step-by-step explanation:

Hey there!!

Let's simply solve it.

Given,

[tex] \frac{1}{2} x + \frac{1}{4} x = 16[/tex]

Now, take LCM.

[tex] \frac{2x + x}{4} = 16[/tex]

Multiply 16 by 4.

[tex]3x = 16 \times 4[/tex]

or, 3x = 64.

Divide 64 by 3.

[tex]x = \frac{64}{3} [/tex]

x= 21.33

Therefore, your answer is option B.
