Answer:

[tex]\sf 2\sqrt{2}[/tex]

Step-by-step explanation:

First find h(10)

   h(x) = 2x - 8

   h(10) = 2*10 - 8

           = 20 - 8

           = 12

[tex]\sf g(x)=\sqrt{x-4}\\\\ g(h(10) = g(12) = \sqrt{12-4}\\[/tex]

                         [tex]\sf = \sqrt{8}\\\\ = \sqrt{2*2*2}\\\\ = 2\sqrt{2}[/tex]

2a+32a=34a

Answer:

x = 6

Step-by-step explanation:

As the function f(x) is an exponencial function, it will grow faster than g(x), that is a linear function.

For small values of x, we have that f(x) < g(x). For example:

f(1) = 1/2 * 2 = 1

g(1) = 5*1 + 2 = 7

f(2) = 1/2 * 4 = 2

g(2) = 5*2 + 4 = 14

So we just need to check some integer values and see when f(x) will be bigger than g(x). It will not be a big value, as the exponencial function grows very fast.

For x = 5, we have:

f(5) = 1/2 * 32 = 16

g(5) = 5*5 + 4 = 29

For x = 6, we have:

f(6) = 1/2 * 64 = 32

g(6) = 5*6 + 4 = 34

For x = 7, we have:

f(7) = 1/2 * 128 = 64

g(7) = 5*7 + 4 = 39

So the largest integer value of x for f(x) ≤ g(x) is x = 6.

Another way to solve this is by plotting both equations, and then checking where they cross, that is, where f(x) = g(x).

Answer:

  x = 6

Step-by-step explanation:

We assume your functions are ...

In general, mixed polynomial and exponential functions have no algebraic solution. That means we need to solve f(x) = g(x) using a table of values, or by graphing.

__

Attached is a graphical solution. It shows the largest value of x for which f(x) = g(x) is x=6.

Check: f(6) = 1/2(2^6) = 32 = g(6) = 5(6) +2

__

Additional comment

We can start with f(x) = g(x) and subtract g(x) from both sides of the equation. This gives ...

  f(x) -g(x) = 0

Many graphing calculators readily identify the zeros of a function or expression. We have used that fact to find the two values of x where these functions are equal: ≈0.32 and 6.

For x>6, the exponential function increases without bound, so the graphs never cross again. Likewise, for x < -0.32, the linear function decreases without bound, so the graphs never cross again.

The lower value of x where the graphs cross is an irrational number near −0.319886722135.

Answer:

Lisa played 4.35 hours over the weekend :)

Step-by-step explanation:

Step-by-step explanation:

If we let the width be w, then the length is w+3.5.

This means that w(w+3.5)=11

w^2 + 3.5w - 11 = 0

2w^2 + 7w - 22 = 0 (multiply both sides by 2)

(2w+11)(w-2)=0

w = -11/2 or w = 2 (disregard w = -11/2 as distance is positive)

This means that w=2, and thus the length is 2+3.5=5.5

Answer: Choice C

f(x) = x+5

===========================================

Explanation:

The input x = -3 has 5 added to it to get x+5 = -3+5 = 2

The diagram shows the "-3" in the input oval pointing to "2" in the output oval.

Through similar steps, we have the input -2 map to the output 3. Also, the input 0 points to the output 5.

The input -5 should map to 0, but 0 isn't in the output list. So we ignore -5 in the input oval.

Answer:

(-4, 2), (-1, -3), (2,0), (4,3).

Step-by-step explanation:

f(x) = y= -x²-x+6

When y is max, f'(x) = 0

f'(x) = -2x-1

Equating to 0,

-2x-1= 0

x= -1/2

Put the value of x in f(x)

y = -(-1/2)² -(-1/2) +6

= -1/4+1/2+6

= 6+1/2

y= 13/2

Step-by-step explanation:

You can simplify the equation to make 4(1+3+9...) The nth term is therefore [tex]3^{n-1}[/tex] so u can substitute that into the equation so 4([tex]3^{n-1}+ 3^{n} + 3^{n+1}[/tex]..). This would simplify to 4([tex]3^0 +3+3^2[/tex]+[tex]3^3+3^4+3^5+3^6+3^7+3^8[/tex]). By simplifying this, you can make it so 4([tex]2^2+6^2+18^2+42^2+81^2[/tex]) = 4(4+36+324+2916+6561) =39364

A. The rolls of groovy wallpaper is needed to cover the apartment bedroom. 9 rolls

B.The cost to re-wallpaper the apartment room $143.10

Based on the question, we have to assume there are no windows and no doors in that bedroom... to calculate how much less wallpaper we really need, and we cover completely from the floor to the ceiling.

A. If one rolls covers 50 sq ft, how many rolls do we need?

First, let's calculate the perimeter of that room, which is 16'x10'.

P = 16 + 10 + 16 + 10 = 52 feet of perimeter.

Now, the walls are 8 feet high... so, let's see just how big is the area to cover.

A = 52 feet * 8 feet = 416 sq feet to cover all walls.

Since we know each roll covers 50 sq ft, we will need:

416 / 50 = 8.32 rolls.

When talking about quantity you need to buy or to fill something, you always have to round up to the next unit.  Because you usually can't buy a portion of a unit and if you round it down, you'll miss material to cover your walls.

So, we will need 9 rolls.

B. Total cost, based on $15.90 per roll.

We already know we need 9 rolls... so how much will it cost us?

C = 9 * $15.90 = $143.10
