Answer:
A = 196 pi m^2
Step-by-step explanation:
The area of a circle is given by
A = pi * r^2
The radius is 14
A = pi *14^2
A = 196 pi m^2
Answer:
-40 x^8
Step-by-step explanation:
-5x*8x^7
We know that a^b * a^c = a^(b+c)
-5 *8 * (x*x^7)
-40 *(x^1 * x^7)
-40 x^(1+7)
-40 x^8

Answer:
You should <u>carry 2 other batteries.</u>
Step-by-step explanation:
If the average life of each battery tends to last 6.9 months, and what you need is a year of battery supply, you probably need to carry two batteries.
The battery inside the flashlight has probably already spent much of its half-life.
We are told that the flashlight already has a battery inside, the batteries are discharged inside the flashlight even if the flashlight is not being used.
Which means that the average life of that battery is wearing out.
It would take 2 more batteries in addition to the one already inside the flashlight to supply the need for these for a year.
Since ABCD is a rectangle, AB and CD are parallel sides. This means that you can set AB equal to CD to solve for x. It would be:
1/2x+6=5/2x-2.
6=4/2x-2
8=2x
4=x
So the answer would be e. 4.
Hope this helps!
