Jul 9, 2017 - First lets find the range of -2 sqrt(x - 3) + 8x cannot be < 3 or f(x) would not be real when x = 3 f(x) = 8 and for all other values of x f(x)
Step-by-step explanation:
Answer:
170 cm^2.
Step-by-step explanation:
This consists of 3 rectangles of same area and 2 triangles of the same area.
= 3 * 10 * 5 + 2 * 1/2 * 5 * 4
= 150 + 20
= 170 cm^2.
Answer:
Step-by-step explanation:
B looks like it would work.
You add speeds * time when you are travelling in opposite directions.
I don't know why you would add or subtract 1 as in A and C
120 * t = 540
t = 540/120
t = 4.5 hours.
So after 4.5 hours they are 540 miles apart.
Answer:
Step-by-step explanation:
Consider triangle ABC with the base AC=36. Let the line DE be parallel to the line AC. If DE||AC, then triangles ABC and DBE are similar. If k is the scale factor of these triangles, then
Thus,
The area of the triangle ABC is
The area of the triangle DBE is
Since line DE divides triangle ABC in two equal area parts, we have that
and
