Step-by-step explanation:
the standard form of a circle equation is
(x - h)² + (y - k)² = r²
where (h, k) is the center of the circle, and r is the radius.
since the center of this circle is the origin (0, 0), we have the simplified version
x² + y² = r²
to get r² we simply use the given point
7² + 1² = r²
49 + 1 = r²
r² = 50
our equation in standard form is therefore
x² + y² = 50
For zeroes/roots r1,r2, r3
the facors of the polynomial is
(x-r1)(x-r2)(x-r3)
roots
-3,2,5
(x-(-3))(x-2)(x-5)
(x+3)(x-2)(x-5)
the coefient of the x term is -4
so mutliply the whole thing by 2
(2)(x+3)(x-2)(x-5)
expand
f(x)=2x^3-8x^2-22x+60
Answer:
1. Linear; 2. C = 2.50x + 40
Step-by-step explanation:
1. Prediction
Yes, it is a linear function, because each additional photo adds the same amount to the cost.
2. Equation
Let C = the cost of the photo package
and x = the number of photos
Then 2.50x = the cost of the photos
And $40 = cost of photo shoot
Then C = 2.50x + 40
