Answers:
Area = 254.34 square feet
Circumference = 56.52 feet
=========================================================
Work Shown:
Area = pi*(radius)^2
A = pi*r^2
A = 3.14*9^2
A = 254.34 square feet
----------------
Circumference = 2*pi*(radius)
C = 2*pi*r
C = 2*3.14*9
C = 56.52 feet
The two results are approximate since pi = 3.14 is approximate.
The answer would be -18/-7
90+90+128= 308
360-308=52
x=52
-4.5
Step-by-step explanation:
the point P is at the midpoint of -4 and -5
Answer:
The equation would be B) y = 5x + 17
Step-by-step explanation:
To start, you need to locate the slope of the first equation. Since the slope is the coefficient of x, we know it to be -1/5. Now, the perpendicular slope is the opposite and reciprocal of that, which makes the new slope 5.
Now that we have this, we can use the point and the slope in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 7 = 5(x + 2)
y - 7 = 5x + 10
y = 5x + 17
