Answer:
[tex]r =5[/tex]
Step-by-step explanation:
Given
[tex](h,k) = (-3,2)[/tex] -- center
[tex](x,y) = (1,5)[/tex] --- pass through
Required
The radius (r)
The equation of circle is:
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
So, we have:
[tex](1 - -3)^2 + (5 - 2)^2 = r^2[/tex]
[tex](4)^2 + (3)^2 = r^2[/tex]
[tex]16+9 = r^2[/tex]
[tex]25 = r^2[/tex]
Take square roots of both sides
[tex]5 = r[/tex]
[tex]r =5[/tex]

A community shares a vegetable garden in a park each summer. Last year, it took Sapphire 88 hours to plant the garden by herself. The year before, it took Varsha 66 hours to plant the same garden by herself.
This year, if Sapphire and Varsha work together to plant the same vegetable garden, it would take ??? hours.
What is ???
Answer:
37.71 hours
Step-by-step explanation:
Saphire
1garden/88hours
Varsha
1garden/ 66 hours
Together
1/88 + 1/66 = x
use 264 as common denominator
3/264 + 4/264 = 7/264
Together they can do 7 gardens in 264 hours
264/7 = 37.71 hours for 1 garden

Rounding in the calculation of monthly interest rates is discouraged. Such rounding can lead to answers different from those presented here. For long-term loans, the differences may be pronounced.
To buy a car, you borrow $28,000 with a term of five years at an APR of 5%. What is your monthly payment? (Round your answer to the nearest cent.)
$
How much total interest is paid? (Round your answer to the nearest cent.)
$
9514 1404 393
Answer:
monthly payment: $528.39interest paid: $3,703.40Step-by-step explanation:
The monthly payment is given by the amortization formula:
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where the annual interest rate is r for t years on loan value P.
Filling in the given information, we find the monthly payment to be ...
A = $28000(0.05/12)/(1 -(1 +0.05/12)^(-12·5)) ≈ $528.39
The monthly payment is $528.39.
__
The total amount repaid is ...
($528.39/mo)(60 mo) = $31,703.40
The interest paid is the difference between this and the loan amount:
interest paid = $31,703.40 -28,000 = $3,703.40
The total interest paid is $3,703.40.

Hi, I need help creating a graph for this math question. Here goes -
It is the end of the semester, and the clubs at school are recording their profits. The Science Club started out with and has increased its balance by an average of per week. The Math Club has saved per week after starting out with at the beginning of the semester.
Answer: Science Club y = 10x + 20 and Math Club y = 5x + 50.
Question: Graph both lines on one set of axes. When do the clubs have the same balance?
Answer:
(6,80)
Step-by-step explanation:
To check
Substitute (6,80) for x & y value
Y = 10x + 20
80 = 10(6) + 20
80 = 60 + 20
80 = 80
Y = 5x + 50
80 = 5(6) + 50
80 = 30 + 50
80 = 80
Answer:
(6.80) is the correct answer
To purchase $14.400 worth of machinery for his business, Greg made a down payment of $1400 and took out a business loan for the rest. After 2 years of
paying monthly payments of $576.18, he finally paid off the loan.
Answer:
below
Step-by-step explanation:
cost of the machinery = $14,400
he paid a deposit of $1400
then later paid $576.18 for two years
two years = 24 months
= $576.18 *24
=$13,828.32
total amount paid
= initial deposit + amount paid in two years
= $1,400 + $13,828.32
=$15,228.32
so he finally paid $15,228.32
interest = selling price - original cost
= $15,228.32 - $14,400
=$828.32
therefore interest = $828.32
4. Type of data that is given as individual data points.
a grouped
c. research
b. questionnaire
d. un grouped
Answer:
Ungrouped
Step-by-step explanation:
Data given as individual data points are usually called Ungrouped data, this is because the data given is raw and not arranged in intervals to form a group of data. This data are usually worked on without having to work with the class size or the midpoint of the intervals. Examples of Ungrouped data could be given as a list of values such as :

A.)55
B.)38
C.)70
D.)20
Answer:
D) 20
Step-by-step explanation:
4x - 10 and x together equal 90
Set your formula up as
90 = 4x - 10 + x
90 + 10 = 4x + x
100 = 5x
100 / 5 = x
20 = x
Which mathematical sentence most Accurately expresses the information in the problem below?
See Picture....
Answer:
Don't quote me on this but it's probably C. 12c ≥ 88
Step-by-step explanation:
This is because he packages 88 eggs into cartons of 12.
88/12 is 7.33333... so it makes sense to have a greater or equal amount of eggs. If you multiply 7.333333... by 12, each additional 3 gets you closer to 88 so again, makes sense to have more.

A wire 15 centimeters long is cut into two pieces. The longer piece is 3 centimeters longer than
the shorter piece. Find the length of the shorter piece of wire.
Answer:
Let the length of the 2 pieces = L and S
Let L = the longer piece and S = the shorter piece
A wire 26 cm is cut into 2 pieces. This equates to......L + S = 26
The longer piece is 6 cm longer than the shorter piece. This equates to.....L = 6 + S. Substitute this equation into the first one, you get
L + S = 26
6 + S + S = 26
2S = 20
S = 20/2 = 10 cm
L = 6 + S = 6 + 10 = 16 cm
To confirm, L + S = 26
16 + 10 = 26!

what additional piece of information do we need to prove that MLN ≅ OPN
Answer:
N is the midpoint of MO
Step-by-step explanation:
Given
See attachment for triangles
Required
Additional information to prove [tex]MLN \cong OPN[/tex]
From the attachment, we already have:
[tex]LM \simeq OP[/tex] and [tex]LN \simeq ON[/tex]
The additional information that must be true for [tex]MLN \cong OPN[/tex] to be true is: N is the midpoint of MO
Because this piece of information proves that:
[tex]MN \simeq ON[/tex]
Which in other words makes [tex]MLN \cong OPN[/tex]
Use a double integral to find the area of the following regions. The region bounded by all leaves of the rose r=2cos3θ
Answer:
Hence the area of the region bounded by all leaves of the rose is [tex]\pi[/tex].
Step-by-step explanation:
Here,
[tex]2 cos (3\Theta )=0\\\Rightarrow cos(3\Theta)=0\\\Rightarrow cos(3\Theta )=cos\left (\frac{\pi }{2} \right )\\\Rightarrow \Theta =\left (\frac{\pi }{6},-\frac{\pi }{6} \right )[/tex]
Now consider for one leaf of rose:-
[tex]Area = 3\int_{-\frac{\pi }{6}}^{\frac{\pi }{6}}\frac{r^{2}}{2}d\Theta \\\\ = \frac{3}{2}\int_{-\frac{\pi }{6}}^{\frac{\pi }{6}}4 cos^{2}\left ( 3\Theta \right ) d\Theta \\\\ = \frac{12}{2}\int_{-\frac{\pi }{6}}^{\frac{\pi }{6}} \frac{cos(6\Theta +1)}{2}d\Theta\\\\ =\frac{6}{2}\left [ \frac{sin(6\Theta +\Theta )}{6} \right ]_{-\frac{\pi }{6}}^{\frac{\pi }{6}}\\\\ =3\times \left [ \frac{\pi }{6}+\frac{\pi }{6} \right ]\\\\ =3\times \frac{2\pi }{6}\\\\ = \pi[/tex]
