The graph that looks like this is the correct answer.
Answer:
1436.75504 or 1372/3π cm^3
Step-by-step explanation:
The volume of a sphere can be found using:
V = 4/3 πr^3
We know the radius is 7, so we can substitute 7 in for r
V = 4/3 π7^3
Evaluate the exponent
V = 4/3 π 343
If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.
v= (4/3*343)π
v=1372/3π
If we want an exact answer, multiply 1372/3 and pi
v=1436.75504
So, the volume is 1436.75504 or 1372/3 π cm^3
Answer:
(t, h(t)) = (4, 9256)
Step-by-step explanation:
We assume you intend the h(t) function to be ...
h(t) = -16t^2 +128t +9000
The equation can be written in vertex form as follows:
h(t) = -16(t^2 -8t) +9000
h(t) = -16(t^2 -8t +16) +9000 -(-16)(16) . . . . add and subtract -16(16) to complete the square
h(t) = -16(t -4)^2 +9256 . . . . . vertex form of the height function
The vertex of h(t) is (4, 9256), an altitude of 9256 feet after 4 seconds.
Choice-'B' is the correct choice . . . 2E9A .
I began converting the original numbers to decimal (base 10),
but decided that 5 points are not worth that much aggravation.
At that point, I wondered whether I could just write it down and
do it like any old other subtraction exercise. I've never done
that before with hex numbers, but I found that I could !
The only place you have to be extra careful is in the third place,
where you have to subtract '9' from '2'. In order to do that, you
have to borrow one from the 'F'. That makes the 'F' an 'E', and
it makes the '2' an '18', from which you can then easily subtract
the '9'. The difference of '2E9A' then jumps right out.
Thank you. I never knew you could just do that.
Answer is B I did it on one of my quiz
