Answer:
Step-by-step explanation:
When you find the volume of prisms, you're essentially taking the area of the base and multiply it by the length, in varied orientations.
In this case, I'd start by finding the area of the parallelogram facing us.
The formula for a parallelogram's area is the same as a rectangle's:
A = b x h
In this case, h = 3 cm and b = 8 cm.
A = 24 cm²
Now, you multiple the area by the length of the parallelogram, which is 8 cm.
V = 24 cm² x 8 cm
= 192 cm³
I hope this helps!
Answer:
First: sec(7pi/6)= -2square root3/3
A1=5
a2=15
a3=45
a2/a1=15/5=3
a3/a4=45/15=3
Sequence is geometric-the ration of each term and previous term is CONSTANT. Ratio is: 3
There is no common difference (d), as sequins not arithmetic.
d=a(n) - a(n-1)
a(n) is last term
a(n-1) is the previous term
d=45-15
d=30
d=15-5=10
The difference between each number in sequence is not the same therefore, there is not common difference.
Good luck.
Answer:
Step-by-step explanation:
depends what K is.
But usually an algabraic letter with no value is equal to one
K=1

To get the average add up the totals and divide by the amount
(12.5+13+13)/3
=38.5/3
=12.833
