Answer:
(x-8)^2+(y+8)^2=7
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2
Substitute h, k, and r for 8, -8, and √7, respectively.
(x-(8))^2+(y-(-8))^2=(√7)^2
The two negatives in y - (-8) causes it to be a +8. Squaring √7 will make it 7.
Answer:
3x³ + 23x² + 63x + 55
Step-by-step explanation:
Given
(3x + 5)(x² + 6x + 11)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(x² + 6x + 11) + 5(x² + 6x + 11) ← distribute both parenthesis
= 3x³ + 18x² + 33x + 5x² + 30x + 55 ← collect like terms
= 3x³ + 23x² + 63x + 55
Line B has slope m = (-3/2-0)/(4-0) = -3/8. The given point is the y-intercept (b = 7), so your equation is
y = mx +b . . . . . . . don't confuse the intercept variable (b) with the name of the line (here I called it B)
y = (-3/8)x +7
46 because 8-3 equals 5 then 5 times 5 equals 25 to then add 11 to finally subtract 66-20 which equals 46
