**Answer 1**

**Answer:**

96 degrees

**Step-by-step explanation:**

Since you know that arc are twice the angle measure, that means arc RT is 42 * 2 = 84. Then, you have to find the measure of RS.

Remember that arc RT and RS have to add up to 180 degrees because they form a semicircle (half of a circle).

To find the measure of RS, just do 180 - 84 = 96 degrees.

### Answers

**Answer:**

13.6 units (to 3 significant figures)

**Step-by-step explanation:**

C ( -4,6) and D (-4,-5)

the formula for distance is : √(x2 - x1)² + (y2-y1)²

in this case x1= -4 , x2= -4 and y1 =6 , y2 = -5

so substitute the values and you will get the answers

A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress with a severe storm class rating. Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. The next 10 waves have an average wave height is 16 feet with a SD of .6 ft. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis

### Answers

**Answer:**

The alternate hypothesis is:

[tex]H_{a} < 16[/tex]

**Step-by-step explanation:**

**There are two types of hypothesis**. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)

**A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.**

This means that the null hypothesis is [tex]H_{0} = 16.4[/tex]

**Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis**

Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:

[tex]H_{a} < 16[/tex]

### Answers

Answer: 1 1/6

Step-by-step explanation: i dont know if this is right, but hope it helps

**Answer:**

1 1/6

**Step-by-step explanation:**

Given function:

find the three beehives honey Lila total collected2/3,1/4,1/4

Combine the terms:

[tex]\frac{2}{3}+\frac{1}{4}+\frac{1}{4}=\frac{2}{3}+\frac{2}{4}[/tex]

Simplfly the fraction terms:

[tex]\frac{2}{3}[/tex]·[tex]4=\frac{8}{12}[/tex] [tex]\frac{2}{4}[/tex]·[tex]3=\frac{6}{12}[/tex]

Combine the terms:

[tex]\frac{8}{12}+\frac{6}{12}=\frac{14}{12}[/tex]

Simplifly the final value:

[tex]\frac{14}{12}=1\frac{2}{12}[/tex] [tex]1\frac{2}{12}=1\frac{1}{6}[/tex]

Therefore, the three beehives gives a total of 1 1/6 honey..

I WILL GIVE YOU 100 points and Braine at Math Properties of Equality, Part 2

For each expression, write an equivalent expression to show the

mathematical properties of equality.

Distributive Property:

6(m +4) = ?

Associative Property:

2 + (m + x) = ?

Commutative Property:

x + 3 = ?

Distributive Property:

3(2y - 6) = ?

Distributive Property:

m(y + 5) = ?

### Answers

**Answer:**

1. 6(m + 4) = 6m + 24

2. 2 + (m + x) = (2 + m) + x

3. x + 3 = 3 + x

4. 3(2y - 6) = 6y - 18

5. m(y + 5) = my +5m

**Step-by-step explanation:**

1. Distributive property "distributes"/multiplies the 6 outside the parentheses to each term inside the parentheses.

2. Associative property deals with how terms and numbers are grouped into parentheses. The terms/numbers stay in the same order.

3. The commutative property means terms can change in order, and you will still get the same result.

4, 5. See #1 above. Distribute/multiply the number/term outside the parentheses to the numbers/terms inside.

If the circumference of a circle measures 3/2TT cm, what is the area of the circle in terms of TT?

A. 3/4 tt cm2

B. 9/2 tt cm2

C. 9/4 tt cm2

D. 9/16 tt cm2

### Answers

**Answer:**

A = pi 9/16 cm^2

**Step-by-step explanation:**

The circumference is 3/2 pi

The circumference is given by

C = 2 * pi *r

3/2 pi = 2 * pi *r

Divide each side by 2 *pi

3/2 pi / 2 pi = 2 pi r /2pi

3/4 cm = r

Now we can find the area

A = pi r^2

A = pi ( 3/4) ^2

A = pi 9/16 cm^2

**Answer:**

d) 9/16π cm²

**Step-by-step explanation:**

Circumference = 3/2π cm

diameter = 3/2 cm

radius = 3/2 ÷ 2 = 3/4 cm

area = π(3/4)² = 9/16 π cm²

A roller coaster is being designed that starts at (0,22) and ends at (19,2),

Along the ride there is a relative minimum at (5,6) and a relative

maximum at (10,18). The roller coaster is almost finished but one

section is missing. Find the correct function that completes the roller

coaster so that the ride is smooth and continuous.

### Answers

**Answer:**

The function is, f(x) = 6·sin((π/5)(x + 3π/2)) + 12

**Step-by-step explanation:**

The general form of equation of a roller coaster is given as follows;

y = A·sin(B(x - C)) + D

Where;

A = The amplitude = (18 - 6)/2 = 6

D = The vertical shift = 12

One revolution = 10 unit

∴2·π = 10 unit

Therefore, 10 = 2·π/B

B = 2·π/10

The phase shift = 3·π/2

Therefore, we have the function as follows;

f(x) = 6·sin(2·π/10(x + 3π/2)) + 12 = 6·sin((π/5)(x + 3π/2)) + 12

**Answer:**

b = 2.8253A = 45.2°C = 107.4°

**Step-by-step explanation:**

The given sides form the given angle, so the Law of Cosines can be used to find the third side.

** b =** √(a² +c² -2ac·cos(B)) ≈ √7.982544072 ≈ **2.8253**

The measure of angle A can be found from the Law of Sines.

** A =** arcsin(a/b·sin(B)) ≈ arcsin(0.71017) ≈ **45.2°**

Angle C can be calculated from the other two angles.

** C =** 180° -27.4° -45.2° = **107.4°**
