If the center of a circle is
(-5,8) and a point on the circle is (-5, -4) What is the radius?
Answer:
The radius is 12.
Step-by-step explanation:
You're given the center and a point on the circle. The point and the center both have an x-coordinate of -5, so there is no horizontal distance between them. The distance is only in the vertical direction. The distance from 8 to -4 is 12. Since this is the distance from the center to a point on the circle, this equals the radius.

15. The area of a rectangular playground is 315 yd? The width of the playground is 6 yd longer than its
length. Find the length and width of the playground.
Answer:
length 21yd
width 15yd
Step-by-step explanation:
Actually it does factor
x(x+6)=315
x²+6x=315
x² +6x - 315 = 0
(x+21)(x-15) = 0
x= -21. discard as can’t have a negative distance
x=15
So dimensions are 15 and 21
The measure of ADB is 162º. What is the measure of <EAB
Answer:
81 degrees
Step-by-step explanation:
Applying the inscribed angle theorem, the measure of ∠EAB is: 81°.
What is the Inscribed Angle Theorem?The inscribed angle theorem states that an intercepted arc measure is always twice the measure of the inscribed angle in a circle.
Given the following:
Inscribed angle = ∠EABIntercepted arc = ADB = 162°We would therefore have the following:
1/2(ADB) = m∠EAB
Substitute
1/2(162) = m∠EAB
m∠EAB = 81°
Therefore, applying the inscribed angle theorem, the measure of ∠EAB is: 81°.

Thanksgiving- 17
New Year's
Thanksgiving 10
New Year's-15
Answer:
Thanksgiving, median = 17
New year's eve, median = 8
Thanksgiving, IQR = 12
New year's eve, IQR = 10
THANKSGIVING has greater variability
Step-by-step explanation:
The median value of a box plot is the line which lies in the middle of the box :
From the plot, the best estimate :
Thanksgiving, median = 17
New year's eve, median = 8
THE Interquartile range, IQR is the difference between the upper quartile and lower quartile values, Q3 - Q1 ;
Lower quartile = the starting point of the box
Upper quartile = the endpoint of the box
From the plot ; Best estimate :
Thanksgiving :
Q1 = 12 ; Q3 = 24
IQR = Q3 - Q1 = 24 - 12 = 12
New year's eve :
Q1 = 5 ; Q3 = 15
IQR = Q3 - Q1 = 15 - 5 = 10
Thanksgiving :
Range = Maximum - Minimum
Range = (29 - 5) = 24
New year's eve:
Range = Maximum - Minimum
Range = 22 - 3 = 19
Hence, Thanksgiving has greater variability

Attendance has never been a component of the grade for this course. However, over the years I have noticed that 40% of those who attend regularly receive an above average grade (B or better), while only 10% of those who do not attend regularly receive an above average grade. About 70% of the students attend class regularly. One student is randomly selected at the end of the semester. Find the probability that the student did not attend class regularly given that (s)he did not receive an above average grade
Answer:
0.3913 = 39.13% probability that the student did not attend class regularly given that (s)he did not receive an above average grade
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Did not receive an above average grade.
Event B: Did not attend class regularly.
Probability of an student not receiving an above average grade:
100 - 40 = 60% of 70%(attend class regularly).
100 - 10 = 90% of 100 - 70 = 30%(do not attend class regularly).
So
[tex]P(A) = 0.6*0.7 + 0.9*0.3 = 0.69[/tex]
Did not receive an above average grade and did not attend class regularly:
90% of 30%. So
[tex]P(A \cap B) = 0.9*0.3 = 0.27[/tex]
Find the probability that the student did not attend class regularly given that (s)he did not receive an above average grade
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.27}{0.69} = 0.3913[/tex]
0.3913 = 39.13% probability that the student did not attend class regularly given that (s)he did not receive an above average grade
Nike marks up the original cost of all of the shoes they sell by 30%. Andre wants to buy a pair of shoes that has a price tag of $117. What was the original cost of these shoes before the 30% markup?
Answer:
$90
Step-by-step explanation:
The shoes now cost 130% of the original cost
The original cost is 100%
Take the new amount and divide it by 130:
117/130 = .90
Then multiply that number by 100 to get the original percent
.90 x 100 = $90
To check, multiply $90 by 130% or 1.30 to make sure that a 30% increase makes the product $117
$90 x 1.30 = $117

A. 1
B. None of the options is correct
C. 0
D. A Constant term is not variable
Answer:
C. 0Step-by-step explanation:
As,
In a constant term the power of the variable is zero, so it's degree is 0.
Eg:
[tex]4 {a}^{0} [/tex]
Since,
[tex] {x}^{0} = 1[/tex]
Hence,
4 × 1 = 4
Here, The value remains unchanged hence it is the constant variable.

Step-by-step explanation:
5. Jerald is investigating the typical depreciation rate for the used automobile he intends to purchase next month. He has collected the following data about an automobile purchased in 1999 for 12,500. a. Using Jerald’s data, find the best-fit exponential equation for this deprecation using the substitution method. Must show work. b. Using the same data, get an equation using the calculator's regression feature. Then estimate the depreciated value of the automobile in 2010:
An exponential equation is characterized by an initial value "a" and a rate "b". Because Jerald is investigating a depreciation, the rate "b" will be less than 1.
The exponential equation is [tex]y = 12500(0.86)^x[/tex] and the depreciated amount in 2010 is approximately 2379
I've added the missing data as an attachment.
An exponential equation is represented as:
[tex]y = ab^x[/tex]
Where:
[tex]a \to[/tex] the first term
[tex]b \to[/tex] rate
[tex]x \to[/tex] years after 1999
[tex]y \to[/tex] depreciated value
When [tex]x = 0\ \&\ y=12500[/tex]
The equation [tex]y = ab^x[/tex] is:
[tex]12500 = ab^0[/tex]
[tex]12500 = a*1[/tex]
[tex]12500 = a[/tex]
[tex]a =12500[/tex]
When [tex]x = 1\, \&\ y = 10750[/tex]
The equation [tex]y = ab^x[/tex] is:
[tex]10750 = ab^1[/tex]
[tex]10750 = ab[/tex]
Substitute [tex]a =12500[/tex]
[tex]10750 = 12500 \times b[/tex]
Solve for b
[tex]b =\frac{10750 }{12500}[/tex]
[tex]b =0.86[/tex]
So, the equation is:
[tex]y = ab^x[/tex]
[tex]y = 12500(0.86)^x[/tex]
To calculate the depreciated value in 2010, we first solve for x in 2010
[tex]x = 2010 - 1999[/tex]
[tex]x = 11[/tex]
So, the depreciated value (y) is:
[tex]y = 12500(0.86)^x[/tex]
[tex]y = 12500 \times 0.86^{11}[/tex]
[tex]y = 2379[/tex]

James wants to purchase a car.
The purchase price of the car is $27,000.00 The dealership will allow him to pay cash or
finance the car with a down payment of $5,000.00 and 60 monthly payments of
$525.00. James chooses to finance the car.
Answer the following questions:
a) What is the amount financed?
b) What is the total amount of monthly payments?
c} What is the amount of the finance charge?
(a) The amount financed is $22,000.
(b) Total amount of monthly payments is $31,500.
(c) Amount of the finance charge is $9,500.
What is Down Payment?Down payment is the amount which has to be paid at the beginning of a transaction while buying a house or a car.
Given that,
Purchase price of the car = $27,000.00
Down payment = $5,000.00
Number of monthly payments = 60
Amount of monthly payment = $525
(a) Amount financed = Purchase price - Down payment
= $27,000.00 - $5,000.00
= $22,000
(b) Total amount of monthly payments = 60 × $525
= $31,500
(c) Amount of the finance charge = $31,500 - $22,000
= $9,500
Hence the amount financed is $22,000.
