Answer:
1.
centre(h,k)=(-13,9)
radius (r)=6
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x+13)²+(y-9)²=6²
(x+13)²+(y-9)²=36you can write this equation too
x²+26x+169+y²-18y+81=36
x²+y²+26x-18y+169+81-36=0
x²+y²+26x-18y +214=0
is a required equation of the circle.
2.
centre(h,k)=(1,-1)
radius (r)=11
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x-1)²+(y+1)²=11²
(x-1)²+(y+1)²=121
you can write this equation too
x²-2x+1+y²+2y+1=121
x²+y²-2x+2y=121-2
x²+y²-2x+2y=119
is a required equation of the circle.
3.
centre (h,k)=(3,1)
radius (r)=4units.
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x-3)²+(y-1)²=4²
(x-3)²+(y-1)²=16 is a required equation.
4.
centre(h,k)=(4,-2)
radius (r)=3
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x-4)²+(y+2)²=3²
(x-4)²+(y+2)²=9
you can write this equation too

a man borrows money 800 for 2 years at a simple interest rate 20%. what is the total amount that must be repaid?
Answer:
3200
Step-by-step explanation:
Simple interest = [ (Principle x Rate x time) /100 ]
Substitute all values: (800 x 2 x 20)/100 = 3200
Hope this helps
Answer:
1120
A=p+I I = prt/100=800x20x2/100=320
A= P+I=800+320=1120

Answer:
3072ft
Step-by-step explanation:
we have,
h(t)=-16t²+192t+2560
where
h -----> is the height in feet of the rock
t -----> the time in seconds
For t=8 seconds
substitute the value of t in the function and find the value of h
h(8)=-16(8)²+192(8)+2560
=3072ft

What is 0.3666... (the 6 is repeating) expressed as a fraction?
Here is what I have so far, i dont know if It is helpful:
If X = 0.36666…, then 100x = 36.6666… and 10x = 3.6666…. We can subtract 10x from 100x to get 90x, which is equal to 36.6666 – 3.6666 or 33. That means 90x = 33.

Solve the following quadratic by
completing the square.
y = x2 + 2x - 6
Answer:
x = - 1 ± [tex]\sqrt{7}[/tex]
Step-by-step explanation:
To solve the equation let y = 0 , that is
x² + 2x - 6 = 0 ( add 6 to both sides )
x² + 2x = 6
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = 6 + 1
(x + 1)² = 7 ( take the square root of both sides )
x + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )
x = - 1 ± [tex]\sqrt{7}[/tex]
PLEASE HELP! What is the lateral area of the can below that has a diameter of 8 and a height that is three times the radius? Round to the nearest tenth. [Hint: Find the radius first]
Answer: 402.1
Step-by-step explanation:
What’s the answer to this?!!
Answer:
52
Step-by-step explanation:
Using the reverse Pythagorean Theorem we can get the answer quite easily. If A^2 + B^2 = C^2, then by that same logic, C^2 - A^2 = B^2. That means 62^2, or 3844, minus 39^2, or 1521, equals 2323. The square root of that is 52.
Hope that this helps!

What is the equation of a circle with center (2,-5) and
radius 4?
Answer:
Choice C
Step-by-step explanation:
The Equation of a circle is (x-h)^2+(y-k)^2=r^2, where h and k are the x and y coordinates respectively of the center of the circle, and r is the radius. Because the center here is (2, -5), we have (x-2)^2+(y- - 5)^2, and the two minuses become (y+5)^2. This eliminates A and B. The radius is 4, so r^2=16, and thus, we get C.

Answer:
To find the surface area of a cone, you need to calculate the cone’s base and the lateral surface area.
Since the base of a cone is a circle, then the base area (B) of a cone is given as:
Base area of a cone, B = πr²
Where r = the base radius of the cone

Multiply both polynomials together
Answer:
6x + 11x - 10
Step-by-step explanation:
So in order to solve this expression, we have to distribute the numbers in each set of parenthasis
Step 1 : break down each mini-espression you're solving
(2x+5)(3x-2)
each term is multiplied by both terms in the other set of parenthasis.
(2x · 3x) + (2x · -2) + (5 · 3x) + (5 · -2)
Step 2 : Solve each idividual piece
(2x · 3x) = 6x²
(2x · -2) = -4x
(5 · 3x) = 15x
(5 · -2) = -10
Step 3 : Put it all together amd simplify
6x² - 4x + 15x - 10
6x² + 11x - 10
