Answer
Find out the value of x.
To prove
Definition of mid- segment
It is a segment connecting the midpoints of two sides of a triangle.
It is always parallel to the third side, and the length of the midsegment is half the length of the third side.
As shown in the triangle given below.
As given
DE = 5x and BC = 11x – 15
Thus
15 = 11x - 10x
15 = x
Therefore the value of x is 15 .
Answer:
0.540
Step-by-step explanation:
Hi there,
To get started in order to solve this, please recall the property of logarithms.
This question is a bit tricky, but doable. Best way to solve this is first compare the two functions:
Now, let's see what the function gives at 13 and 1:
Something to recognize is that 1 to the power of <em>anything</em> is just 1, so f(1) is reduced to:
We are making progress!
Next, we can set both f(13) forms equivalent to each other, watch this:
but we know what f(1) is equal to, and let's substitute our knowns:
the c constant on both left and right side cancel out:
Now, take the logarithm form of both side of the equation. I used natural log, but you can also use common logs:
⇒
this was performed using <em>the power log rule. </em>
Isolate k:
using a calculator.
