Answer:
D
Step-by-step explanation:
You can look at it like a right triangle being made with the vertical part being 9 and the horizontal part being 8, then you want to find the diagonal part. So that's the Pythagorean theorem
Answer:
189.3 square inches, 55.7 inches
Step-by-step explanation:
Area = area of rectangle + area of semicircle
area of rectange = 10 * 15 = 150 square inches
radius of semicircle = 10/2 = 5
area of circle = (pi * 5^2)/2 = 12.5pi square inches
total area = 150 + 12.5pi = 189.3 square inches
total perimeter = perimeter of rectangle - left side + perimeter of semicircle
perimeter of rectangle = 10 + 15 + 15 = 40 inches
perimeter of semicircle = 10pi/2 = 5pi inches
total perimeter = 40 + 5pi = 55.7 inches
Answer:
x-intercept is (3.6,0)
y-intercept is (0,-2)
Step-by-step explanation:
Given the linear graph: -5x + 9y = -18
X-intercept is when y=0;
-5x + 0 = -18
-5x = -18
x = 18/5 = 3.6
The x-intercept therefore is (3.6,0)
Y-intercept is when x = 0;
0 + 9y = -18
9y = -18
y = -18/9 = -2
Therefore y-intercept is (0,-2)
