Find the approximate solution(s) to each of the following equations graphically. Use technology to support your
ser-zykov [4K]

Answer: x" = 5.69

Step-by-step explanation:

The graphic solution is attached.

Verifying the solution:

Existence condition: x > 0

2x - 4 = √x + 5

√x =2x - 4 - 5

√x =2x - 9 (²)

x = (2x - 9)²

x = 4x² - 36x + 81

4x² - 36x - x + 81 = 0

4x² - 37x + 81 = 0

Δ = -37² - 4.4.81 = 1369 - 1296 = 73

x = 37 ±√73/8                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          

x' = 3.55

x" = 5.69

checking:

2*3.55 - 4 = 3.1

√3.55 + 5 = 6.88 Its not the same ∴ 3.55 is not a solution

2*5.69 - 4 = 7.39

√5.69 + 5 = 7.39 ∴ it's the only solution

Natalka [10]

Answer:

$12,400

Step-by-step explanation:

Given:

Week earning + 9% commission = $1,916

Weekly Earning = $800

Commission for the Week = $1,916 - $800 = $1,116

Let total sales for the week = x

Therefore, x = ($1,116 * 100)/9

x = $12,400

For a right circular cylinder, if the radius is tripled and the height is shrunk down to half its size, then what is the surface
Elden [556K]

The surface area of a cylinder that the radius tripled and it height is brought down to half is 3890.46 inches²

<h3 /><h3>How to find the surface area of a cylinder?</h3>

Surface area of a cylinder = 2πr(r + h)

Therefore,

radius is tripled = 3(7) = 21 inches

height is shrunk half its size = 17 / 2 = 8.5 inches

Therefore,

surface area = 2 × 3.14 × 21 (21 + 8.5)

surface area = 131.88(29.5)

surface area = 3890.46 inches²

Hello, maybe you could please take 5 minutes out of your day to help me please :) id really appreciate it!
Vadim26 [7]

Answer:

D

Step-by-step explanation:

Alright, so we know that they can unload 25 trucks in 5 hours.

If we do 25/5 We find out that they can unload <u>5 trucks per hour</u>

Unfortunately, that is not one of the answers, so we will have to do some investigating to find something that is <u>equivalent</u>!

After evaluating the available answers, you can find that answer D lines up with our first assumption!

Every 1/5th of an hour the Fast-Pack people can unload a truck!

We can calculate this by writing:

1/5*25=<u>5</u>

<u></u>

Please let me know if you have any confusion! :)
