Answer:
D;
(x + 1/2)^2 + (y- √57)^2 = 81
Step-by-step explanation:
Mathematically, the general equation of a circle is given as;
(x-a)^2 + (y-b)^2 = r^2
where (a,b) represents the circle center and r represents the radius of the circle
Thus, we have this as follows;
(a,b) = (-1/2, √57) , r = 9
Substituting these values;
(x + 1/2)^2 + (y- √57)^2 = 9^2
9
5x+3x-3= 8x+16-10
5x+3x-8x=16-10+3
8x-8x=9
= 9
0
all real numbers are solutions
100°
Total angle in a triangle is 180
∠C = 180 - 20 - 60
= 180 - 80
= 100
The answer is B)
First, we look at what we know. There are two points on the graph that we know, (0, 0) and (15, 5). This can give us the slope of the line.
y2 - y1 / x2 - x1 | Plug in our coordinates
5 - 0 / 15 - 0 | 5 / 15 | 1/3. Our slope is 1/3. This means that for each inch of length, the ramp rises .33 inches.
