Answer:
Step-by-step explanation:
The equation of this ellipse is
for a vertical oriented ellipse where;
(h,k) is the center
c=distance from center to the foci
a=distance from center to the vertices
b=distance from center to the co-vertices
You know center of an ellipse is half way between the vertices , hence the center (h,k) of this ellipse is (0,0) and its is vertical oriented ellipse
Given that
a= distance between the center and the vertices, a=7
c=distance between the center and the foci, c=√33
Then find b
The equation for the ellipse will be
Hello,
Answer C
center (0,0)
b=3
c=7==>a²=c²+b²=49+9=58
x²/58+y²/9=1
Answer:
Slope is 1; y-int is (0, 0)
Step-by-step explanation:
<u>Step 1: Identify the slope</u>
The slope is the number attached to the x. Since in this problem there is no number or sign, that means that number in front of it is 1.
y = 1x is same as y = x
So... the slope is 1
<u>Step 2: Identify the y-int</u>
The y-int is the number after the mx, also known as b. In this problem there is no number after, that means that the y-int is 0.
y = mx + b
y = 1x + 0
So... the y-int is (0, 0)
Answer: Slope is 1; y-int is (0, 0)
First we will find the 11th term
an = a1 + (n-1) * d
a11 = 12 + (11 - 1) * 5
a11 = 12 + 10 * 5
a11 = 12 + 50
a11 = 62
now we use the sum formula...
Sn = (n (a1 + an)) / 2
S11 = (11 (12 + 62)) / 2
S11 = (11 (74)) / 2
S11 = 814/2
S11 = 407
Answer:
Angle A is F Angle A = 57. 52+71=123. 180-123=57
