10 divided by 2 is 5, 5 + 8 is 13
thus f(10)= 13
hope this helps

$f(x)= \frac{x}{2} + 8 \\ \\ f(10)= \frac{10}{2}+8=5+8=\boxed{13 }$

I don’t understand this one

Answer:

see below

Step-by-step explanation:

Put -1 where x is in each expression and evaluate it.

You will find that the expression is zero when the numerator is zero. And you will find the numerator is zero when it has a factor that is equivalent to ...

(x +1)

Substituting x=-1 into this factor makes it be ...

(-1 +1) = 0

Evaluating the first expression, we have ...

$\dfrac{4(x+1)}{(4x+5)}=\dfrac{4(-1+1)}{4(-1)+5}=\dfrac{4\cdot 0}{1}=0$

This first expression is one you want to "check."

You can see that the reason the expression is zero is that x+1 has a sum of zero. You can look for that same sum in the other expressions. (The tricky one is the one with the factor (x -(-1)). You know, of course, that -(-1) = +1.)

Evaluate the piece-defined function for the given of x by matching the domain values with the range values

Elenna [48]

Answer:

The correct answer is:

(1) d

(2) b

(3) a

(4) c

(5) e

Step-by-step explanation:

The given problem is incomplete. Find the attachment of the full question.

According to the question,

(1)

By putting x = -2, we get

$f(x)=(-2)^3-5$

$=-8-5$

$=-13$

(2)

By putting x = 0, we get

$f(x)=(0)^3-5$

$=0-5$

$=-5$

(3)

By putting x = 3, we get

$f(x)=8$

(4)

By putting x = 9, we get

$f(x)=(2)^{9-7}$

$=(2)^2$

$=4$

(5)

By putting x = 11, we get

$f(x)=(2)^{11-7}$

$=(2)^4$

$=16$

Ln20+ln5=2ln x
ln(20*5) = ln x^2
ln 100 = ln x^2
100 = x^2
x = 10 second option

Hayden has 6 rolls of dimes there are 50 dimes in each roll. How many dimes does he have altogether

DerKrebs [107]

This is pretty simple. :) Since you have 6 rolls of dimes with 50 dimes in each, you would just do 6*50 which equals 300. So Hayden has 300 dimes altogether. Hope this helps! :)
