Prove that 3 power p + 1 - 3 power P upon 2 multiply 3 power p is equal to 1 ​

Mathematics

Anit [1.1K]3 years ago

Answer:

see explanation

Step-by-step explanation:

note that 3^{p+1} = 3^{p} × 3 ( when multiplying exponents are added )

Given

\frac{3^{p+1}-3^{p}  }{2.3^{p} } ← factor out 3^{p} on numerator

= \frac{3^{p}(3-1) }{2.3^{p} }

= \frac{2.3^{p} }{2.3^{p} }

= 1

When Katy planted a large bush in her garden, it was 4 feet tall. Now it is 75% taller. How tall is the bush now?
ddd [48]

Answer:

3

Step-by-step explanation:

So to answer this question we need to see what it is actually telling us and not telling us.

*4 feet tall

*75 percent taller

They aren't telling us how tall it is now.

To solve this problem, multiply 4x75%

That will give you 3.

The bush is 3 feet tall now.

Solve<br> 13^x+2=5<br> having a bit of trouble
-Dominant- [34]
<em>Solve: </em>13^{x} + 2 = 5

Start by isolating the x-variable as much as you can:
13^{x} = 5 - 2 = 3
13^{x} = 3

Now, if we take the log with base 13 of both sides, then the left hand side will cancel out really easily. This is based on the concept of inverse operations. For example, when we take the square of a square root, we get our initial value. This is because the two operations are inverses of each other, and basically undoes each other.

Logarithms and exponentials are the inverse operations of each other. If we want to extrapolate the power of an exponential, we take the logarithmic function of it, and vice versa.

In this case, we are saying what power of '13' will produce us with 13ˣ, and the only answer will be x itself.

log_{13}(13^{x}) = log_{13}(3)
x = log_{13}(3)

Which do you think is the best description of the area of the room? (circle your choice.)
nevsk [136]

My vote would be b. because generally when we are figuring area of a room, we are working with materials that are not exact and we usually round off .75 to the next foot. (I have experience in flooring!)

I am sure there are situations where you would want it to be exact however, such as using VERY expensive materials to cover.
