Answer: height of the door is x+4
Step-by-step explanation:
- <em>area of the whole circle = r^2 times pi</em>
- radius is 10 units
- thus, the whole circle's area is 100pi square units.
...and this shape is exactly one quarter, one-fourth, of the whole circle. <em>Why? because of the shape's right angle and radius. (when you multiply 90 times 4, it will equal 360 degrees, which is the angle of a whole circle.)</em>
so 100pi divided by 4 equals 25pi square units of the shape.
ANSWER:
25 pi square units
(or in decimals: multiply 25 by 3.14 which would be 78.5 square units)
F(x) = x - 0.15x
sale = original - 0.15(original)
y = 0.85x
Answer:
(-5, -3)
Step-by-step explanation:
Scale factor 1/2 means divide points by 2
Answer:
f and g have the same value at x = 3 and again at x = 7.
Step-by-step explanation:
Note that f(3) = g(3) = -9, and that
f(7) = g(7) = 2.
