F(d)=(d+1)(d-1+6)
f(d)=(d+1)(d+5)
f(2)=(2+1)(2+5)
f(2)=(3)(7)
f(2)=21
12000
Just do
120000 divided by 10
Answer:
30 mph
Step-by-step explanation:
time = distance/speed
If x represents Jane's speed along the summit then her total exploration time is ...
12/x + 40/(x -5) = 2 . . . . . hours
Multiplying by (x)(x -5), we get ...
12(x -5) +40(x) = 2(x)(x -5)
Dividing by 2 and subtracting the left side gives ...
x^2 -31x +30 = 0
(x -30)(x -1) = 0 . . . . . factor
Solutions are x = 30 and x = 1, values of x that make the factors zero. A speed of 1 mph makes no sense in this problem, so ...
Jane's speed along the summit was 30 mph.
4/6= 8/12
9/12
therefore 9/12 is greater
Answer:
Step-by-step explanation:
We know that the volume of a cone:-
(r = 10) (h = 6)
<u>Divide numbers:-</u>
<u>Multiply numbers:-</u>
Therefore, your answer is 200π³
We could also multiply 200 by 3.14 which will give you 628 units³.
