Answer:

Step-by-sf(-5)=17

tep explanation:

Let Q(x) be the quotient of \frac{f(x)}{x+5}.

Let R be the remainder. R is a constant real number because we are dividing by a linear factor, x+5.

\frac{f(x)}{x+5}=Q(x)+\frac{R}{x+5}

Multiply both sides by (x+5):

f(x)=Q(x)(x+5)+R

Substitute x=-5:

f(-5)=Q(x)(-5+5)+17  (We were given R=17 since they did say the remainder is 17.)

f(-5)=Q(x)(0)+17

f(-5)=17

Answer:

  f(\boxed{-5})=\boxed{17}

Step-by-step explanation:

The remainder theorem tells you that f(a) is the result of division of f(x) by (x-a).

Here, you have f(x)/(x+5) = 17, so a=-5 and f(-5) = 17.

Which of the following represents the difference between ten and a number is the sum of eight and a number"?
Alona [7]

9514 1404 393

Answer:

  (c)  10 -N = 8 +N

Step-by-step explanation:

The difference between 10 and a number is (10 -N).

The sum of 8 and a number is (8 +N).

In this context, "is" means "equals," so we have ...

  10 -N = 8 +N

Members of a junior high basketball team want to brag about how tall they are. First, they measured each player’s height in inch
enyata [817]

First to find the median we need to put the numbers in order from least to greatest.

62, 64, 65, 66, 67, 69, 83

Now take a number from each side

64, 65, 66, 67, 69

Once again.

65, 66, 67

On last time

66

So the median is 66.

Now to find the mean we must add all the numbers up

64+67+83+65+66+62+69

which equals 476

Now divide 476 by the total number of heights which is 7

476/7=68

So the mean is 68

Answers: Mean; 68 Median; 66

Harmonic mean if a number h such that (h-a)/(b-h)=a/b Prove h is H(a,b) iff satisfies either relation a. (1/a)-(1/h) = (1/h) - (
Fudgin [204]
A.

\displaystyle\frac1a-\frac1h=\frac1h-\frac1b
\implies\displaystyle\frac{h-a}{ah}=\frac{b-h}{bh}
\implies\displaystyle\frac{h-a}{b-h}=\frac{ah}{bh}
\implies\displaystyle\frac{h-a}{b-h}=\frac ab

b.

\displaystyle h=\frac{2ab}{a+b}
\displaystyle\implies\frac{h-a}{b-h}=\frac{\frac{2ab}{a+b}-a}{b-\frac{2ab}{a+b}}
\displaystyle\implies\frac{h-a}{b-h}=\frac{2ab-a(a+b)}{b(a+b)-2ab}
\displaystyle\implies\frac{h-a}{b-h}=\frac{ab-a^2}{b^2-ab}
\displaystyle\implies\frac{h-a}{b-h}=\frac{a(b-a)}{b(b-a)}
\displaystyle\implies\frac{h-a}{b-h}=\frac ab

The other direction can be proved by following the manipulations in the reverse order.
