Answer:
(x+10)² + (y-8)² = 41
Step-by-step explanation:
First, we find the length of the diameter.
from distance formula, d = SQR ROOT OF [(-14+6)² + (13-3)²]
diameter = SQR ROOT OF [8² + 10²] = √164 = √4√41 = 2√41
***** so the radius is half that, r =√41
The center of the circle is at the midpoint of the diamater.
x = (1/2)(-6 + -14) = (1/2)(-20) = -10
y = (1/2)(3 + 13) = (1/2)(16) = 8
center (h,k) = (-10,8)
circle equation: (x-h)² + (y-k)² = r²
(x- -10)² + (y - 8)² = (√41)²
(x+10)² + (y-8)² = 41
Sorry it took a while.
Does any one know how to do 2r+4<8 it’s aggravating me
Answer:
Step-by-step explanation:
2r+4<8
subtract 4 from both sides
2r<4
divide by two
no need to reverse the sign since you are not dividing by a negative number
r<2
Determine the number of solutions of the system.
y = 2x - 1
y = -2x + 3

find the length of IR using the special right triangles
Answer:
7
Step-by-step explanation:
This is a 30-60-90 triangle. The side that include the 60 degree angle and the 90 degree symbol side length is half of the hypotenuse. The hypotenuse is 14 so IR is 7.
HELPPP im confused :/
Answer:
D.
Step-by-step explanation:
The sides correspond with a favor of 1.5
12/8 = 1.5
7.5/5 = 1.5
3/2=1.5
Could someone explain how to do this, I have no idea how...
Answer:
2a²
Step-by-step explanation:
Pair 'like' terms with 'like' terms, ie numbers go with numbers, and 'a's go with 'a's.
Lets deal with the top of the fraction first:
4ax3a³
Rearrange it so you have numbers beside numbers and 'a's beside 'a's:
(4x3)x(axa³)
12x(a⁴) (because nᵃxnᵇ=nᵃ⁺ᵇ)
12a⁴
Now, instead of (4ax3a³)/6a², we have 12a⁴/6a²
First divide the numbers: 12/6 =2
Now divide the 'a' parts: a⁴/a²=a² (because nᵃ/nᵇ=nᵃ⁻ᵇ)
Now we have 2a²

What is the approximate volume of the cylinder?
Answer:
V ≈ 509 m3 ← This is an approximate answer, rounded to the nearest whole. To calculate the volume of a cylinder, multiply the area of the base (Πr2) times the height (h). This gives the formula V = Πr2h.
