Answer:

5.7, 6.9, 5, 7.1

Step-by-step explanation:

The absolute value of a number shows its distance from 0 on the number line, meaning it must always be positive since distance is positive. You have to perform the operations indicated on each expression to the left and match it to the correct value on the right. I got 5.7, 6.9, 5, 7.1 in order from top to bottom after adding and subtracting the numbers to the left.

46.The function f graphed above is the function f(x) = log2(x) + 2 for x > 0. Find a formula for the inverse of this function

pantera1 [17]

Answer:

The inverse for log₂(x) + 2 is - log₂x + 2.

Step-by-step explanation:

Given that

f(x) = log₂(x) + 2

Now to find the inverse of any function we put we replace x by 1/x.

f(x) = log₂(x) + 2

f(1/x) =g(x)= log₂(1/x) + 2

As we know that

log₂(a/b) = log₂a - log₂b

g(x) = log₂1 - log₂x + 2

We know that log₂1 = 0

g(x) = 0 - log₂x + 2

g(x) = - log₂x + 2

So the inverse for log₂(x) + 2 is - log₂x + 2.

Find an expression which represents the difference when (6x-3y) is subtracted from (9x+2y) in simplest terms.

Alex73 [517]

Answer:

$3x+5y$

Step-by-step explanation:

Subtract (6x-3y) from (9x+2y):

$(9x+2y)-(6x-3y)$

This can also be seen as:

$(9x+2y)-1(6x-3y)$

Distribute the -1 to (6x-3y):

$(9x+2y)-1(6x)-1(-3y)\\\\(9x+2y)-6x+3y$

Simplify the parentheses:

$9x+2y-6x+3y$

Group like terms:

$(9x-6x)+(2y+3y)$

Combine:

$3x+5y$

This expression can't be further simplified. Therefore, 3x+5y is the answer.

The function f(t)=-16 + 100 models the height of a ball, in feet, dropped from a 100-foot rooftop at time t, in seconds.

Mazyrski [523]

Using it's concept, it is found that the average rate of change of the function during the interval from 0 to 2 seconds is given by:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

$r = \frac{f(b) - f(a)}{b - a}$

In this problem, the function is given by:

f(t) = -16t² + 100.

The outputs are given as follows:

f(0) = -16(0)² + 100 = 100.

f(0) = -16(2)² + 100 = 36.

Hence the average rate of change is given by:

r = (36 - 100)/(2 - 0) = -32 ft/s.

And the correct option is:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.

Find the nonpermissible replacement for a in this expression 7/6a

vredina [299]

The correct answer for the exercise shown above is:

zero (0)

The explanation is shown below:

1. You have the following expression given in the problem above:

7/6a

2. By definition, <span>the nonpermissible replacement for a is the value that make the denominator equal to zero.

3. Keeping this on mind, you have:

7/6a=7/6(0)=7/0

Therefore, as you can see, the answer is: zero (a=0).
