Answer:
6.3 yards
Step-by-step explanation:
mathematically, to get the circumference of the circle, we will have to use the formula for the circumference of a circle
we have this as;
C = 2 * pi * r
r is 1 yard
c = 2 * pi * 1 = 2pi yards = 6.3 yards
A = (1/2) b * h
h = b - 5
42 = (1/2) * b * (b - 5)
42 = (1/2) * b^2 - 5b
multiply both sides by 2 to clear the fraction (1/2)
2(42) = 2(1/2) *b^2 - 5b
84 = b^2 -5b
Since this is a quadratic equation, subtract 84 from both sides so that it is set = to zero.
b^2 - 5b - 84 = 0
Now factor.
(b - 12)(b + 5) = 0
b - 12 = 0; b = 12
b + 5 = 0; b = -5
You can't have a negative length so the answer is 12m
To check the answer:
A = (1/2) * 12* 7
A = 42 m^2
Answer:True
Step-by-step explanation:
The slopes of parallel lines are equal, two lines are parallel if their slopes are equal and they have different y-intercepts.....? for short "if lines are parrallel, then their slopes are the same.
Greater than is the answer to that question
Answer:
Step-by-step explanation:
x-intercept → Plug in 0 for <em>y</em><em> </em>to get −3 for <em>x</em>
y-intercept → When <em>x</em><em> </em>is set equal to 0 [(0, −6)]
