Answer 1

Answer:

Area of the sector = 78.54 square meters

Step-by-step explanation:

Radius of the given circle = 10 meters

Sector bounded by the arc having measure = 90°

Angle subtended by the arc at the center = 90°

Area of the sector = [tex]\frac{\theta}{360}(\pi r^{2})[/tex]

Here angle θ is the angle at the center subtended by the arc.

If angle θ = 90°

Therefore, area of the sector = [tex]\frac{90}{360}(\pi)(10)^{2}[/tex]

                                                = 25π

                                                = 78.54 square meters

Answer:

1.  144  2. 16 3. 1   4. 3x-6  

Step-by-step explanation:

So think of this as a function in a function.  So you work from the inside to the outside.  So for problem 1, we start with f(4)) [you read it "f of 4"] so what is the solution when x = 4, since f(x) means the function of x so f(4) means 'the function of 4' inside f(x).  

Since f(x) = 3x then f(4) = 3(4) [notice how you substitute the 4 everywhere you see a letter x]

so f(4) = 12, now you work the next part h(f(4)) since f(4)=12 then h(12)

So take the h(x) function which is h(x) = [tex]x^{2}[/tex] then h(12) = [tex]12^{2}[/tex] so h(12) = 144

Answers

Answer: (A) 72

Step-by-step explanation:

1. 12m x 2m = 24

2. 12m x 4m = 48

3. add both answers together 24m + 48m = 72

increase a length of 24m so that the ratio of the new length to the old length is 11:8.

Answers

Answer:

33m

Step-by-step explanation:

If the ratio of the new length to the old length is 11:8 (simplified ratio)

I like to set up a proportion, like this,

x/24 = 11/8, where x is the undefined new length

x*8 = 24*11 (cross multiply)

8x = 264 (multiply)

x = 33 (divide 8 by both sides)

The new length is 33m.

Hope I helped! Good Luck!

Answer:

33m

Step-by-step explanation:

The 8 part of the ratio refers to the old length 24m

Divide by 8 to find the value of one part of the ratio

24m ÷ 8 = 3m ← value of 1 part of the ratio, then

11 parts = 11 × 3 = 33m

Thus

33m : 24m = 11 : 8

Question attached - will give brainliest if correct.

Answers

Answer:

Perimeter = 54

Step-by-step explanation:

Since AC = RP, then the following also applies:

AB = RB

CB = PB

So, in order to determine this, you first need to find a common ratio in order to find the missing side of PB which you need for the perimeter.

To determine the ratio you do the following:

AB = 21 (14 + 7)

RB = 7

21: 7   = 3: 1

This means in finding a smaller side you can divide by the value 3 to find it.

It also means that side CP is 2/3 of the value of CB which means that we need 1/3 of the value left in order to determine PB:

CP = 10 = 2/3, which means 1/3 is 5, so

PB = 5

Therefore: CB = 15

Perimeter = CB + AC + AB

15 + 21 + 18 = 54

Answer:. 38 and 52

It is given here that

angle FKY = 90.

we know angle. FKG + GKY. = FKY

so,. (7c + 24) + (5c + 42) = 90

12c + 66 = 90

12c = 90 - 66

12c = 24

c= 24/12

c = 2

then angle is

7*2+24 = 38

5*2 + 42 = 52

The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally believed that they will win. Comparing the location of the game and the number of wins, a correlation coefficient of −0.91 is calculated. What would this imply about the football team winning at home?

A The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.

B The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.

C The scatter plot would not be represented by a line of best fit with a negative slope.
There is a weak correlation between the football team playing at home and winning.

D There is no causation and almost no correlation between the football team playing at home and winning.

Answers

Using correlation coefficients, it is found that the correct option is:

B The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.

What is a correlation coefficient?It is an index that measures correlation between two variables, assuming values between -1 and 1.If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.It also is the slope of the line of best fit.

In this problem, the correlation coefficient of −0.91, meaning that there is a strong inverse relation between the location of the game and the team's winning percentage, that is, the team is more likely to win on the road, hence, option B is correct.

Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.

Answer:

(2, 0 )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 4 → (1)

3x - 7y = 6 → (2)

Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate x

6x + 9y =  12 → (3)

- 6x + 14y = - 12 → (4)

Add (3) and (4) term by term to eliminate x

0 + 23y = 0

23y = 0

y = 0

Substitute y = 0 into either of the 2 equations and solve for x

Substituting into (1)

2x + 3(0) = 4

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 )

Which statement about 2(x+4) is true?
A) 2( x + 4 ) is a quotient
B) 2 ( x + 4 ) is a product
C) 2 ( x + 4 ) has four terms
