The coordinates of the vertices of the triangle shown are A(2, 13), B(10, 5) and C(12, 14). What is the length of segment AB in units?
9514 1404 393
Answer:
8√2 units
Step-by-step explanation:
The distance formula is useful.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((10 -2)² +(5 -13)²) = √(64 +64)
d = 8√2
The length of AB is 8√2 units.

Write an exponential function in the form y
and (5,2187)
9514 1404 393
Answer:
y = 9(3^x)
Step-by-step explanation:
We assume you want a function in the form ...
y = a(b^x)
that passes through points (0, 9) and (5, 2187).
Filling in the given point values, we have ...
9 = a(b^0) = a
2187 = a(b^5) = 9(b^5) . . . . using the above value of 'a'
Dividing the second equation by 9 and taking the 5th root, we find b.
(2187/9) = b^5
243^(1/5) = b = 3
The exponential function is ...
y = 9(3^x)
Mandy and Randy are each playing with a beach ball. Mandy's ball has a diameter of 12 inches. Randy's ball has a diameter that is twice as large as Mandy's ball. How much larger is the volume of Randy's ball? Show and explain your reasoning.
Answer:
Randy's ball is 904.78 larger than Mandy's.
Step-by-step explanation:
Using math, we find that Mandy's ball is 904.78 inches in volume and if Randy's is twice the size that's, 904.78 x 2 = 1809.56. so Randy's ball is 904.78 larger than Mandy's

In 2002, there were 450 households in the city of Klean that recycled. Each year since 2002, the number of
households that recycle has grown by 8%. Write a function to represent the number of households
in Klean that recycle x years since 2002.
Answer:
450 x 1.08 ^ X = N
Step-by-step explanation:
Since in 2002, there were 450 households in the city of Klean that recycled, and each year since 2002, the number of households that recycle has grown by 8%, to write a function to represent the number of households in Klean that recycle X years since 2002 the following mathematical reasoning should be raised:
450 (initial number) x 1.08 (8% is added to the initial number) ^ X (years) = Number of households that recycle
450 x 1.08 ^ X = N
Thus, for example, if said number were calculated in 2007, that is, 5 years after 2002, the equation would apply as follows:
450 x 1.08 ^ 5 = N
450 x 1.4693 = N
661.20 = N
If you deposit $300 in an account with a 6% interest rate, how much will be in your account after 1 year? If you leave this money in the account, how much will be in your account after 2 years?
Answer:
I only know the first question, If you leave that money for 1 year it would equal $480 basically, $300 x 1.6 = $480.
Step-by-step explanation:
The required amount in your account after 2 years will be $337.08.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Here,
If you deposit $300 in an account with a 6% interest rate, the amount in your account after 1 year can be calculated as follows:
Find the interest earned after one year:
Interest earned = (6/100) x 300 = $18
Add the interest earned to the original amount:
Total amount after 1 year = $300 + $18 = $318
Therefore, the amount in your account after 1 year will be $318.
If you leave this money in the account for another year, the amount in your account after 2 years can be calculated as follows:
Find the interest earned after two years:
Interest earned in year 1 = $18
Interest earned in year 2 = (6/100) x $318 = $19.08
Add the interest earned to the original amount and the interest earned in year 1:
Total amount after 2 years = $300 + $18 + $19.08 = $337.08
Therefore, the amount in your account after 2 years will be $337.08.

find the value for x y and z
Answer:
All triangles add up to 180 degrees so...
180 - 43 - 59 = 78 degrees.
So x - 78 degrees.
x and y are supplementary angles so...
180 - 78 = 102.
So y = 102.
180 - 102 - 49 = 29 degrees
So z = 29 degrees

a) Find the slope, x-intercept, y-intercept of the line (L):
3x+4y-6= 0 and draw its graphs.
b) Find the equation of a line perpendicular to the line (L) in part (a) and
passing through the point (1, -2).
Answer: 2, 1.5 , -0.75
(b) [tex]4x-3y-10=0[/tex]
Step-by-step explanation:
Given
line is [tex]3x+4y-6=0[/tex]
Converting it into intercept form
[tex]\Rightarrow 3x+4y=6\\\\\Rightarrow \dfrac{3x}{6}+\dfrac{4y}{6}=\dfrac{6}{6}\\\\\Rightarrow \dfrac{x}{2}+\dfrac{y}{1.5}=1[/tex]
So, the x-intercept is [tex]2[/tex] and y-intercept is [tex]1.5[/tex]
The slope is given by
[tex]-\dfrac{\frac{1}{2}}{\frac{1}{1.5}}=-0.75[/tex]
(b) the line perpendicular to the above line and passing through [tex](1,-2)[/tex]
The slope of the required line
[tex]m=-\dfrac{1}{-0.75}\\\\m=\dfrac{4}{3}[/tex]
Equation of the line is given by
[tex]\Rightarrow \dfrac{y-(-2)}{x-1}=\dfrac{4}{3}\\\\\Rightarrow 3y+6=4x-4\\\Rightarrow 4x-3y-10=0[/tex]

Morgan bought a sofa for $216.00. The finance charge was $25 and she paid for it over 15 months.
Use the formula Approximate APR =(Finance Charge÷#Months)(12)Amount Financed
to calculate her approximate APR.
Round the answer to the nearest tenth.
9.4%
9.3%
1.2%
1.1%
Answer:
9.3%
Step-by-step explanation:
Morgan's approximate APR is approximately 1.0%.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Using the given formula:
Approximate APR = (Finance Charge ÷ Months) x 12 / Amount Financed
We know that the amount financed is the total cost of the sofa minus the finance charge, which is:
Amount Financed = $216.00 - $25.00 = $191.00
We also know that the finance charge was $25.00 and she paid for it over 15 months, so:
Finance Charge ÷ Months
= $25.00 ÷ 15
= $1.67
The approximate APR is:
Approximate APR = ($1.67 x 12) ÷ $191.00 = 0.1393
Rounding this to the nearest tenth gives us 0.1, which is equivalent to 1.0% as the nearest percentage.
Therefore,
Morgan's approximate APR is approximately 1.0%.

Answer:
If a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.
Step-by-step explanation:
Taking into account the educational table provided, if a resident who is 30-49 years old is chosen at random, to determine what is the probability that they have completed a bachelor's degree and no more the following calculation must be performed:
30-39 Bachelor's degree = 1576
40-49 Bachelor's degree = 443
30-39 Total = 4062
40-49 Total = 2869
4062 + 2869 = 100
1576 + 443 = X
6931 = 100
2019 = X
2019 x 100/6931 = X
201900/6931 = X

Jose bought a 10-pound bag of food for his dog.
He fed his dog one-half of a pound of dog food
each day. Which equation is used to determine,
y, the amount of dog food that remains at the
end of each day, x?
The answer choices are on the top. Also please don’t send me links :) <3
Answer:
B
Step-by-step explanation:
so your starting value (10) is not going to have the x by it. instead he is feeding his dog so it will be subtracted from.
x is the number of days he can feed his dog. this will be mulitplied with something.
0.5 is how much he feeds his dog each day. this will be times the number of days or x.
so it makes your answer [tex]y=10-0.5x[/tex]

(2.2)
B. (5,7)
10
O C. (5.3)
O D. (7/ 2 )
SUBMI
Answer:
(2.5 , 3.5)
Step-by-step explanation:
We can use the midpoint formula . Here the points are , (2,2) and (3,5) .
• Using Midpoint Formula :-
⇒ M = { (x1 + x2)/2 , (y1 + y2)/2 }
⇒ M = ( 2+3/2 , 5+2/2 )
⇒ M = ( 5/2 , 7/2 )
⇒ M = ( 2.5 , 3.5 )
Hence the midpoint is (2.5 , 3.5)With individual lines at its various windows, a post office finds that the standard deviation for normally distributed waiting times for customers on Friday afternoon is 7.2 minutes. To test this claim, the post office experiments with a single, main waiting line and finds that for a random sample of 25 customers, the waiting times for customers have a standard deviation of 3.5 minutes. a) With a significance level of 5 percent, conduct an appropriate test on the claim. (State your null hypothesis, test statistic, critical value, decision rule, conclusion) (15 points) b) What is the 95% confidence interval for the population variance
Answer:
H0 : σ²= 7.2²
H1 : σ² < 7.2
We can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.
Step-by-step explanation:
H0 : σ²= 7.2²
H1 : σ² < 7.2²
The test statistic :
X² = [(n - 1)*s² ÷ σ²]
s² = 3.5
n = sample size = 25. ; s²
X² = [(25 -1)*3.5² ÷ 7.2²
X² = (24 * 3.5^2) / 7.2^2
X² = 5.67
Pvalue from Chisquare statistic :
P(X² < 5.67) = 0.000042
Pvalue < α ; we reject the Null.
Hence, we can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.
