Answer:

f(-5)=-125

Step-by-step explanation:

we have

f(x)=x^3\\\\x=-5\\\\f(-5)=(-5)^3\\\\f(-5)=-125

Answer: f(-5)=-125

Step-by-step explanation:

For this problem, we are given f(x)=x³ and x=-5. Since we are given x=-5, we plug that into f(x) and solve.

f(x)=x³            [plug in x=-5]

f(-5)=(-5)³      [exponent]

f(-5)=-125

Now, we know that f(-5)=-125.

In a word processing document or on a separate piece of paper, use the guide to construct a two-column proof proving AC &gt; EF
VARVARA [1.3K]

<em>Answer:</em>

Complete proof is written below.

Facts and explanation about the segments shown in question :

  1. As BC = EF is a given statement in the question
  2. AB + BC = AC because the definition of betweenness gives us a clear idea that if a point B is between points A and C, then the length of AB and the length of BC is equal to the length of AC. Also according to Segment addition postulate, AB + BC = AC. For example, if AB = 5 and BC= 7 then AC = AB + BC → AC = 12
  3. AC > BC because the Parts Theorem (Segments) mentions that if B is a point on AC between A and C, then AC > BC and AC>AB. So, if we observe the question figure, we can realize that point B lies on the segment AC between points A and C.
  4. AC > EF because BC is equal to EF and if AC>BC, then it must be true that the length of AC must greater than the length segment EF.

Below is the complete proof of the observation given in the question:

1. BC = EF                                    1. Given

2. AB + BC = AC                         2. Betweenness

3. AC > BC                                   3. Def. of segment inequality

4. AC > EF                                   4. Def. of congruent segments

Noah's brother sells cars and earns 4.5% commission. He sold a truck for $62,000. How much commission will his brother earn?
MA_775_DIABLO [31]

Answer:

the commission earn by his brother is $2,790

Step-by-step explanation:

The computation of the commission earn by his brother is as follows

= Selling price of the truck × commission percentage

= $62,000 × 4.5%

= $2,790

Hence, the commission earn by his brother is $2,790

We simply applied the above formula so that the correct value could come

And, the same is to be considered
