Answer:
Step-by-step explanation:
The integral from a to 4 is ...
We want the value of this to be 12, so we can write ...
-3/2a^2 +a +20 = 12
3a^2 -2a -16 = 0 . . . . . subtract the left side and multiply by 2
(3a -8)(a +2) = 0 . . . . . factor
a = 8/3 or -2 . . . . . . . .values of a that make the factors zero
The only possible values of a are 8/3 and -2.
Answer:
96 i think
Step-by-step explanation:
Answer:
5a-7=24
5a=24+7
a=31/5
Step-by-step explanation:
Cubes have 6 numbers
3 odd, 3 even
probablity=desiredoutcome/totalpossibleoutcomes
there are 6 total desired outcomes (3 on each cube)
total possible, there are 6*6 or 36 total possible outcomes
so 6/36 or 1/6 chance
C. Supplementary
This means their angles add up to 180° which is a straight line
