8
f(5) = 1/4*2^(5)
f(5) = 1/4*32
f(5) = 8
Product of q and 5= 5q (Constant is always first, followed by variable)
Product divided by 2= 5q/2 .
∴ Expression=<u> 5q/2 </u>
(-20)7=140
All the other options have a wrong product. The first option forgot to include te negative sign. The second and last option were supposed to be positive not negative.
The third option is the only one that has a correct product so that means it is correct.
Answer:
See Below
Step-by-step explanation:
The surface area of cylinder is given by the formula:
Where
r is radius ( diameter is 4, so radius is 4/2 = 2)
h is height ( h = 9)
Lets find original surface are:
<u>Halving diameter:</u>
diameter would be 4/2 = 2, so radius would be 2/2 = 1
So, SA would be:
<u>Halving height:</u>
Height is 9, halving would make it 9/2 = 4.5
Now, calculating new SA:
Original SA is ,
Halving diameter makes it
Halving height makes it
So, halving diameter does not have same effect as halving height.
Answer:
RV = 18
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, then
RV = RT = × 36 = 18
