The general form of the equation of a circle is Ax2 + By2 + Cx + Dy + E = 0, where A = B 0. If the circle has a radius of 3 unit

s and the center at (0, 4), which set of values of A, B, C, D, and E correspond to the circle?
A.A = 0, B = 0, C = 2, D = 2, and E = 3
B.A = 1, B = 1, C = 8, D = 0, and E = 9
C.A = 1, B = 1, C = 0, D = -8, and E = 7
D.A = 1, B = 1, C = -8, D = 0, and E = 0
E.A = 1, B = 1, C = 8, D = 8, and E = 3

Ax^2 + By^2 + Cx +Dy + E = 0
radius = 3
standard form of the circle is
(x-a)² + (y-b)² = r², where (a,b) is the center, and r the radius
(x-0)^2 + (y-4)^2 = 9
x^2 + y^2 - 8y + 16 -9 = 0
x^2 + y^2 - 8y + 7 = 0
A=1, B=1,C= 0, D= -8, and E = 7

answer is
<span>C.A = 1, B = 1, C = 0, D = -8, and E = 7</span>

A pile of sand has a weight of 90kg.
ankoles [38]

Answer:

9Kg, 18Kg and 63 Kg

Step-by-step explanation:

Sum the parts of the ratio, 1 + 2 + 7 = 10 parts

Divide the weight of sand by 10 to find the value of one part of the ratio

90 Kg ÷ 10 = 9 Kg ← value of 1 part of the ratio, thus

2 parts = 2 × 9 Kg = 18 Kg

7 parts = 7 × 9 Kg = 63 Kg

Thus the weights of each bag are 9 Kg, 18 Kg and 63 Kg

What is the slope of the line that passes through the given points (3 2) and (5 12)
forsale [732]
Slope is calculated using:
slope = (change in y) / (change in x)
slope = (12 - 2) / (5 - 3)
slope = 10/2 = 5
