What is the equation of a circle with a center located at (-3, 4) and a diameter of 14?
Answers
Answer: (x + 3)^2 + (y - 4)^2 = 49
Step-by-step explanation:
The equation of a circle given the center and radius: (x - h)^2 + (y - k)^2 = r^2
Given: center (-3,4) ; h = -3 and k = 4
diameter = 14
To find the radius: divide the diameter by 2 = 14/2 = 7 = r
Center: (-3,4) and radius: 7
Equation of a circle: (x - h)^2 + (y - k) ^2 = r^2
Substitute h = -3, k = 4, r = 7
(x - (-3))^2 + (y - 4)^2 = 7^2
Answer:
Equation of the circle: (x + 3)^2 + (y - 4)^2 = 49
Write the equation for a circle with a center at (-7 , -4) and a radius of 2.
Answers
Answer:
(x + 7)² + (y + 4) ² = 2²
Step-by-step explanation:
Start with the standard equation of a circle with center at (h, k) and radius r:
(x - h)² + (y - k)² = r²
Here we are given that h = -7, k = -4 and r = 2, and so we obtain:
(x + 7)² + (y + 4) ² = 2²
Step-by-step explanation:
The answer is above, as well as the equation used to get to the answer.
Given the diagram below, find the height of the shorter tree.
16.2 m
7 m
13 m
19.7 m
Answers
Answer:
h = 13 m
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
[tex]\frac{h}{39}[/tex] = [tex]\frac{16}{48}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )
3h = 39 ( divide noth sides by 3 )
h = 13

Answers
Answer:
(6,0), (6,1), (6,2) (6,3)...
Step-by-step explanation:
x = 6
This means that 6 is the x-intercept since this is the equation for a verticle line, this means that x remains in 6 and y is the only number that moves so the AB stake point could be any number where x is 6, it could even be (6,0),
(6,1) e.t.c.
What is the amount of interest that Sam will pay on his $5000 loan if his monthly payment for three years is 150
Answers
Answer:
Amount of interest pay by Sam = $400
Step-by-step explanation:
Given:
Amount of loan taken by Sam = $5,000
Monthly payment made by Sam = $150
Number of year payment made by Sam = 3 Year
Find:
Amount of interest pay by Sam
Computation:
Total amount pay by Sam in 3 year = Monthly payment made by Sam x 12 x 3
Total amount pay by Sam in 3 year = 150 x 12 x 3
Total amount pay by Sam in 3 year = $5,400
Amount of interest pay by Sam = Total amount pay by Sam in 3 year - Amount of loan taken by Sam
Amount of interest pay by Sam = $5,400 - $5,000
Amount of interest pay by Sam = $400

The price of a visit to the dentist is $50. If the dentist fills any cavities, an additional charge of $100 per cavity
gets added to the bill.
If the dentist finds n cavities, what will the cost of the visit be?
Answers
Answer:
I believe the answer will be 50+100n dollars
Step-by-step explanation:
n is the number of cavities so however many cavities there is, it gets multiplied by 100, in this case, it is 100*n which is 100n. So your final cost would be 50+100n dollars.
