Answer:
Step-by-step explanation:
The center tells you how to handle the left side of a circle's equation.
(x - 2)^2 + (x - 1)^2 = r^2
The point (5,2) gives you enough information to find r^2
x = 5
y = 2
(5 - 2)^2 + (2 - 1)^2 = r^2
(3)^2 + 1^2 = r^2
9 + 1 = r^2
r^2 = 10
Complete equation
(x - 2)^2 + (y - 1)^2 = 10
Hello!
This is right because the goal of solving a quadratic equation is to isolate the variable and then solve it. First you multiply - 8/3 to both sides to isolate s and the you solve the equation by multiplying - 8/3 to - 6
Answer:
F(2, 11/2)
Step-by-step explanation:
The expression:
(x-2)² = 10(y - 3)
can be rewritten in the vertex form as follows:
(x-2)² = 10y - 30
(x-2)² + 30 = 10y
1/10(x-2)² + 3 = y
General vertex form is:
y = a(x-h)² + k
then, the vertex is locate at (h, k). In this case the vertes is (2, 3), and <em>a </em>= 1/10
The focus of a parabola is located ar F(h, k+p), where <em>p</em> = 1/(4a). Replacing into these equations:
p = 1/(4*1/10) = 5/2
F(2, 3+5/2) = F(2, 11/2)
Answer:
The equation is <u>sale price</u>=p and the original price is $41.09.
.70
Step-by-step explanation:
sale price= (1-.30)p
<u>sale price=.70</u>p
.70 .70
<u>sale price</u>=p
.70
<u>28.76</u>=p
.70
$41.09=p
