The Obama family is building a circular swimming pool. If the radius of the pool is 15 feet, What is its circumference? Use I = 3.14 to solve.
Answers
The formula for circumference is given by
C = pi *d where pi = 3.14 and d is the diameter
We can find the diameter from the radius
d = 2*r where r is the radius
C = pi * 2 *r
C = 3.14 * 2 * 15
C =94.2 ft

What is parallel lines?
Parallel lines are coplanar, straight lines in geometry that don't cross at any point. When two planes in the same three-dimensional space are parallel, they never cross. Curves that maintain a set minimum distance from one another and do not touch or intersect are said to be parallel curves.
If parallel lines are cut by a transversal , then corresponding angles are equal in measure.
∴ ∠B≅∠F
∠A≅∠E
∠C≅∠G
∠D≅∠H
If parallel lines are cut by a transversal , then interior angles on the same side are supplementary.
∠C+∠E=180°
∠D+∠F=180°
If one of the angles ( let it be ∠E) formed measures 122°, then m∠C=180°-122°=58°.

Professional athletes are some of the highest paid people in the world. The average major league baseball player's salary has climbed from $1,998,000 in 2000 to $2,866,500 in 2006
Answers
Answer:
[tex]L(y)=144750y+1998000[/tex]
The slope means that each year the average professional baseball player's salary increased by $144,750 for every year after 2000.
The y-intercept means that in year 0 (2000) the average professional baseball player's salary was $1,998,000
The predicted average salary in 2007 is $3,011,250
(b)
[tex]E(y)=1998000\cdot1.062^y[/tex]The initial value represents the average professional baseball player's salary in year 0 (2000), which was $1,998,000.
The growth factor means that the rate of change increases each year by 1.062 times the previous year's increase.
The predicted average salary in 2007 is $3,044,233.94
Explanation:
The problem gives us two pieces of information:
In year 2000, we call t = 0, the average salary was $1,998,000
In year 2006, we call t = 6, the average salary was $2,866,500
If we want to make a function of the average salary variation over the years, we have two points that must lie in the equation of that function:
(0, 1998000) and (6, 2866500)
For (a) we need to assume that is linear growth. The equation of a line is:
[tex]y=mx+b[/tex]Where:
m is the slope
b is the y-intercept. In this case, since we established the year 2000 as t = 0, b = 1998000
Given two points P and Q, we can find the slope by the formula:
[tex]\begin{gathered} \begin{cases}P=(x_P,y_P){} \\ Q=(x_Q,y_Q)\end{cases} \\ . \\ m=\frac{y_Q-y_P}{x_Q-x_P} \end{gathered}[/tex]Then, if we call:
P = (0, 1998000)
Q = (6, 2866500)
[tex]m=\frac{2866500-1998000}{6-0}=\frac{868500}{6}=144750[/tex]Thus, the equation of the linear growth model is:
[tex]L(t)=144750t+1998000[/tex]Now, we can use this to find a prediction for 2007. 2007 is 7 years since 2000; thus t = 7
[tex]L(7)=144750\cdot7+1998000=1013250+1998000=3011250[/tex]In (b) we assume an exponential growth. The formula for the exponential growth is:
[tex]y=a(1+r)^t[/tex]Where:
a is the initial value. In this case, the average salary in 2000, $1,998,000
r is the ratio of growth. We need to find this value
t is the time in years
Then, we can use the point (6, 2866500), and the fact that a = 1998000:
[tex]2866500=1998000(1+r)^6[/tex]And solve:
[tex]\begin{gathered} \frac{2866500}{199800}=(1+r)^6 \\ . \\ \sqrt[6]{\frac{637}{444}}=1+r \\ . \\ 1.062=1+r \end{gathered}[/tex]We call the term "1 + r" growth factor.
Now, we can write the formula:
[tex]E(t)=1998000\cdot1.062^t[/tex]To find a prediction of the average salary in 2007, we use the function and t = 7:
[tex]E(7)=1998000\cdot1.062^7=1998000\cdot1.5236=3044233.937[/tex]
-4x - 3 = -11x + 16
Answers
We want to find which value must have x, so this equation is true:
-4x - 3 = -11x + 16
In order to solve the equation for x, we want to "leave it alone" on one side of the equation.
In order to do that we just have to remember one simple rule:
Finding xStep 1- taking all the terms with x to one side
We are going to take all the terms with x to the left side:
-4x - 3 = -11x + 16
↓ adding 11x both sides
11 x - 4x - 3 = 11x -11x + 16
↓ since 11x - 4x = 7x (left) and 11x - 11x = 0 (right)
7x - 3 = 0 + 16
7x - 3 = 16
Step 2- taking all the numbers to the other side
7x - 3 =16
↓ adding 3 both sides
7x - 3 + 3 = 16 + 3
↓ since -3 + 3 = 0 (left) and 16 + 3 = 19 (right)
7x + 0 = 19
7x = 19
Step 3- leaving x alone on the left side
7x = 19
↓ dividing 7 both sides
7x/7 = 19/7
↓ since 7x/7 = x (left) and 19/7 ≅ 2.7
x ≅ 2.7
Answer: x = 19/7 ≅ 2.7

3The number of hours that the employees at the local Fry's grocery store worked last week is normallydistributed with a mean of 28 hours and a standard deviation of 4. What percentage of employees workedbetween 24 and 36 hours?Answer:
Answers
We can solve this question by using the fact that a normal distribution is symmetric and using the empirical rules. The empirical rules are
• 68% of the data falls within one standard deviation of the mean.
• 95% of the data falls within two standard deviations of the mean.
• 99.7% of the data falls within three standard deviations of the mean.
In our problem, the mean is 28 and the standard deviation is equal to 4. Our interval is 24(one standard deviation below the mean) and 36(2 standard deviations above the mean)
[tex](24,36)=(28-4,28+8)=(28-\sigma,28+2\sigma)[/tex]Our area is the area that falls within one standard deviation of the mean plus the area between one standard deviation and two on the positive side. The first area is 68% of the data, and the second area we can calculate using the fact that a bell curve is symmetric. Since 68% of data falls within one standard deviation and 95% of the data falls within two standard deviations of the mean, the difference between them represents the data that falls between one standard deviation and two standard deviation.
[tex]95-68=27[/tex]Since the distribution is symmetric, the data that falls between one standard deviation and two standard deviation on the positive side is half of this value.
[tex]\frac{27}{2}=13.5[/tex]Now, we just add this value to 68% and we're going to have our answer.
[tex]68+13.5=81.5[/tex]The percentage of employees worked between 24 and 36 hours is 81.5%.

An irrational number is a number that cannot be expressed as a ratio or fraction of two integers, such as pi or roots.
Options A and C cannot be correct because they each have two irrational numbers multiplying one another.
Simplifying Option D, we have:
[tex]\begin{gathered} 3\cdot\text{ }\sqrt[]{9} \\ \Rightarrow\text{ 3 }\cdot\text{ 3} \\ =\text{ 9 } \end{gathered}[/tex]The correct option is B, because:
[tex]\begin{gathered} \frac{1}{4}\cdot\text{ }\sqrt[]{44} \\ \frac{1}{4}\cdot\text{ }\sqrt[]{4\cdot\text{ 11}} \\ \frac{1}{4}\cdot\text{ 2 }\cdot\text{ }\sqrt[]{11} \\ \frac{1}{2}\sqrt[]{11} \end{gathered}[/tex]That is an irrational number that is a product of a rational number and an irrational number.

Given that we only have two points known in the parabola, the best way to determine the equation (having the options already) is to substitute the points on each equation to see which one is true for both points:
[tex]\begin{gathered} y=x^2+3x+2 \\ \text{for (-1,0)}\colon \\ 0=(-1)^2+3(-1)+2 \\ \Rightarrow0=1-3+2=3-3=0 \\ \text{for (3,0)}\colon \\ \Rightarrow0=(3)^2+3(3)+2=9+9+2=20 \end{gathered}[/tex]As we can see on the previous example, when we substitute the point (3,0), we get a contradiction, since 0=20 can never happen. Working this way we find that the equation y=x^2-2x-3 yields the desired results:
[tex]\begin{gathered} y=x^2-2x-3 \\ on\text{ (-1,0):} \\ 0=(-1)^2-2(-1)+3=1+2-3=0 \\ on\text{ (3,0):} \\ 0=(3)^2-2(3)-3=9-6-3=9-9=0 \end{gathered}[/tex]Therefore, the equation of the parabola is y=x^2-2x-3

[tex]\begin{gathered} f(x+5)=(x+5)^2+2(x+5)+4 \\ f(x+5)=(x^2+2\cdot5x+5^2)+(2x+10)+4 \\ f(x+5)=x^2+10x+25+2x+10+4 \\ f(x+5)=x^2+12x+39 \end{gathered}[/tex]Answer: f(x+5) = x² + 12x +39
A farmer fell asleep under a tree in his apple orchard while thinking about pie. While he was sleeping, a squirrel knocked an apple off a branch of the tree. The function f (d) = (see photo) can be used to find the amount of time in seconds that it takes for the apple to drop acertain distance d, where d is in meters.Step 1 of 3 : If the apple was connected to a branch that was 3 meters above the farmer's head, how long would it take before the applehit the top of the farmer's head? Round your answers to the nearest hundredth.

Solution
Step 1
Write the time function equation
[tex]f(d)\text{ = }\sqrt{\frac{2d}{9.8}}[/tex]Step 2
d = 3 meters
[tex]\begin{gathered} f(3)\text{ = }\sqrt{\frac{2\times3}{9.8}} \\ f(3)\text{ = 0.78 seconds} \end{gathered}[/tex]Final answer
0.78 seconds
