This is duo at 9:00 PLEASE HELP Please Reflect (3,-2) over the y-axis?​

Answer:

1. 60°

2. The sum of angles of a triangle is 180°. Since it's an equilateral, all 3 angles are the same.

180 ÷ 3 = 60°

Answer:

2*(5x+4) + 2*(3x+2)

= 10x + 8 + 6x + 2

= 16x + 10

The perimeter of the rectangle, in feet, is represented by (16x + 10)

Answer:

(16x + 12) ft

Step-by-step explanation:

Perimeter of the rectangle = 5x + 4 + 3x + 2 + 5x + 4 + 3x + 2

Perimeter of the rectangle = (16x + 12) ft

Answer:

25 feet per second.

Step-by-step explanation:

Let s represent the speed of the water and r represent the radius of the whirlpool.

The speed in a whirlpool varies inversely with the radius. Therefore, we can write that:

[tex]\displaystyle s=\frac{k}{r}[/tex]

Where k is the constant of variation.

We know that the speed is 2.5 feet per second when the radius is 30 feet.

So, s = 2.5 when r = 30. Substitute:

[tex]\displaystyle 2.5=\frac{k}{30}[/tex]

Solve for k:

[tex]k=30(2.5)=75[/tex]

So, our equation is:

[tex]\displaystyle s=\frac{75}{r}[/tex]

Then when the radius is three feet, r = 3. Evaluate for s:

[tex]\displaystyle s=\frac{75}{(3)}=25\text{ feet per second}[/tex]

So, the speed of the water in a whirlpool with a radius of three feet is 25 feet per second.

To determine which relation is a function, we need to check if each input value (x) corresponds to a unique output value (y). If there is any repetition in the x-values, then it is not a function. in option (0, 0), (1, 1), (2, 2), (3, 3), (4,7) no repetition x-values so c is correct.

Let's analyze each option:

A. (8,-4), (8,4), (6,-3), (6,3), (0, 0)

In this relation, we can see that both 8 and 6 have repeated as x-values. Therefore, option A is not a function.

B. (4, 7), (8,5), (6,4), (5, 3), (4, 2)

Again, we notice that 4 appears twice as an x-value. Hence, option B is not a function.

C. (0, 0), (1, 1), (2, 2), (3, 3), (4,7)

Here, each x-value is unique. No repetition is observed. Therefore, option C represents a function.

D. (0, 0). (1, 0), (1, 1), (2, 1), (1, 2)

In this relation, the x-value of 1 appears three times. Consequently, option D is not a function.

To summarize, option C is the only relation that represents a function since it has distinct x-values corresponding to unique y-values.

Option C is correct answer

We know that,

Volume of sphere = 4/3πr³

41572 = 4/3 × 22/7 × r³

41573 × 21/88 = r³

³√9,920.82 = r

21.48 cm = r

:)

The radius of a sphere with a volume of 41572 cm³ is,

⇒ 21.4 cm

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Now, To find the radius of a sphere with a volume of 41572 cm³, we can use the formula for the volume of a sphere as;

⇒ V = (4/3)πr³

where V is the volume and r is the radius.

Hence, We can rearrange this formula to solve for r:

⇒ r = ∛ (3V/4π)

Substituting the given volume, we have:

r = ∛ (3(41572)/4π)

r ≈ 21.4 cm

Therefore, the radius of the sphere to the nearest tenth of a centimeter is 21.4 cm.

Answer:

72π (I think)

Step-by-step explanation:

Think of it in terms of the entire circle. A semi-circle is just half a circle, so the area of a semicircle will be half of the area of the entire circle. The radius of the semicircle is 6, so the radius of the whole circle is 12. Then, we can do [tex]\frac{pi*r^{2} }{2}[/tex] to get the area of the semicircle is 72π. I'm pretty sure that's right.

Answer:

C(F) means Celcius temperature value from Fahrenheit temperature

Step-by-step explanation:

C(F) is Mathematically interpreted as C of F, this means the value of C obtained for a given F value, that is we have a relation, expression or formular exoressed in terms of F which can be used to obtain the Value of C for a given value of F by making necessary substitution.

Here the relation or expression is c(f)=5/9(f-32).

Hence, once we are given a particular F value, we can substitute that into the equation and obtain the corresponding C temperature value.

Answer:

for 50 pulls, 12.5 blue socks, but you cant have half of a sock so we say 12

for 1000 pulls, 250 blue socks

for 10,000 pulls, 2500 blue socks

Step-by-step explanation:

First we add 5, 7 and 8 to find the total number of socks, 5+7=12 and 12+8 = 20

5 is the amount of blue socks, so

5/20 * how many pulls are conducted is the probability for blue socks

7 is the amount of pink socks, so

7/20 * how many pulls are conducted is the probability for pink socks

and

8 is the amount of yellow socks, so
