Answer:
12.4
Step-by-step explanation:
FD is marked as 6.2. It is a "midline" parallel to AC. A midline is half as long as the side it is parallel to.
AC = 2×6.2
AC = 12.4
Answer:
C y = 3/2x - 1/8
Step-by-step explanation:
We know that the line has a positive slope, because it goes up from the lower left to upper right
We can eliminate B and D
For y = 6x - 11/8
A slope of 6 is very steep
Putting in 6
y = 6*6 -approximately 1 = 35 so the value at 3 would be 35
This is too big
Checking C
y = 3/2(6) - 0 = 9 or 9 This would be about right
It should just be 3 15/16 because you can’t really simplify 15/16 because it’ll just give you decimals. For example; 15/3 is 5 but 16/3 is 5.333.... and 15/5 is 3 and 16/5 is 3.2, and 15/2 is 7.5 and that won’t work because it turns into a decimal.
Answer:
y-7=-2(x+3)^2
Step-by-step explanation:
Vertex Form
y = a(x-h)^2 + k
move the 7 by adding it to both sides in order to get it into vertex form.
The answer can't be C or D because the unit of volume is always cubed. The formula for volume of cylinder is (pi)(r^2)(h) . The pi(r^2) part is the formula for area of a circle which is what the base of the cylinder is. Fortunately the area is already given as 28.2. Plug that into the volume formula and plug in 3.1 for the height and multiply. I get 87.42 and the answer choice B seems to be the closest option
