What is the equation of the circle with center (2,-5) that passes through the point (-2,10).
(x-2) ^2 + (y+5)^2=25
(x+2) ^2 +(y-5)^2=241
(x-2)^2 +(y-5)^2=241
(x+2)^2 + (y-5)^2=25
Answer:
b is the answer
Step-by-step explanation:
The radius of the a circle is:
is a line segment with its endpoints on the circle.
is a line segment from the center of a circle to a point on the circle
is a chord that passes through the center of a circle. It is twice the length of a radius of that circle
is a part of a circle with all its points on the circle

Answer:
Aonnalin, great name :) answer as below
Step-by-step explanation:
They tell us to use slope-intercept form. This is something you will just have to remember y = mx+b
It is confusing b/c there is the other one, the point-slope formula too. but just remember both and know that the point-slope one is to get to the slope-intercept one. y-y1 = m(x-x1)
m= slope
m = (y2-y1) / (x2-x1)
P1= (0,7) in the form (x1,y1)
P2 =(8,-2) in the form (x2,y2)
m = -2-7 / 8-0
m = -9 / 8
now that we have the slope, just use either point with the point-slope
y-7 = (-9/8)(x-0)
y-7 = -9x/8
y = -9x/8 + 7
y = [tex]\frac{-9}{8}[/tex] X + 7
slope-intercept form :)
what is 2 3/4 as an improper factor..? just asking
Answer:
11/4
Hope this helps
Answer:
11/4
Step-by-step explanation:
An improper factor is a fraction that has a higher numerator (number in top) than the denominator (number in the bottom). Some examples of improper factors are 9/8 or 5/3 bc the top number is higher than the bottom one.
You can get the answer by multiplying 2 × 4 bc we want to know how many fourths (1/4) are in 2. In this case there are 8
then we add 8/4 with 3/4 to get 11/4

Determine the numerical value of x
Answer:
x = 10
Step-by-step explanation:
OA = OD ( both radii of the circle )
OD = OB + BD = x + 16
OB is at right angles to OB ( line from centre to midpoint of chord is right )
Using Pythagoras' identity in right triangle ABO
OA² = OB² + AB² , that is
(x + 16)² = x² + 24²
x² + 32x + 256 = x² + 576 ( subtract x² from both sides )
32x + 256 = 576 ( subtract 256 from both sides )
32x = 320 ( divide both sides by 32 )
x = 10

160 - 55 = 105
105 ÷ 35 = 3
Answer:
3 hours
Step-by-step explanation:
First, we must turn this into an equation:
35n + 55 = 160
N = number of hours
Next, solve:
35n + 55 - 55 = 160 - 55
35n = 105
n = 3

4) Haleakela is a 10,000 foot high dormant volcano on Maui, Hawaii. The peak is a horizontal distance of 30,000 feet from the ocean. At what angle would you have to look up to see the peak if you were standing at the edge of the ocean?
ITS 67 dgrees Step-by-step explanation: NP BRAINLIEST OR NA :)?
The angle that you would have to look up to see the peak if you were standing at the edge of the ocean is 18.4°.
Angle:Let x represent the angle
Tan x=Height/Horizontal distance
Tan x =10,000/30,000
x=Tan^-1 (1/3)
x=18.4°
Inconclusion the angle that you would have to look up to see the peak if you were standing at the edge of the ocean is 18.4°.

A quantity with an initial value of 650 grows exponentially at a rate of 20% every week. What is the value of the quantity after 70 days, to the nearest hundredth?
Answer:
4024.62
Step-by-step explanation:
the value in 70 days can be determined using his formula
FV = P (1 + r)^n
FV = Future value
P = Present value = 650
R = growth rate = 20%
N = number of weeks = 70 / 7 = 10 weeks
650 x (1.2)^10 = 4024.62
Answer:
The Answer is 4024.62
