Answer:

Step-by-step explanation:

$f(x) = \frac{2x + 6}{3x} \\ \\ g(x) = \frac{ \sqrt{x} - 8}{3x}$

To find ( f - g)(x) , subtract g(x) from f(x)

That's

$( f - g)(x) = \frac{2x + 6}{3x} - \frac{ \sqrt{x} - 8}{3x}$

Since they have a common denominator that's 3x we can subtract them directly

That's

$\frac{2x + 6}{3x} - \frac{ \sqrt{x} - 8}{3x} = \frac{2x + 6 - ( \sqrt{x} - 8) }{3x} \\ = \frac{2x + 6 - \sqrt{x} + 8 }{3x} \\ = \frac{2x - \sqrt{x} + 6 + 8 }{3x}$

We have the final answer as

Hope this helps you

Bethany has a garden box that is 4. feet long, 8 feet wide, and foot deep . How many cubic feet of dirt does she need to fill th

Firdavs [7]

You need to work out the area so

Area of a rectangle is l x b

So

A= l x b
A= 8 x 4
A= 32

Therefor 32 cubic feet of dirt is needed

What is the volume of these rectangular prisms?

anzhelika [568]

Volume of a rectangle prism is found by <em>multiplying length, width, and height</em>.

So:

3. 9 1/3 * 4 * 6 1/2 = 28/3 * 4 * 13/2 = 1456/6 = 242 2/3 in³

4. 2 1/2 * 5 3/4 * 8 = 5/2 * 23/4 * 8 = 920/8 = 115 yd³

<h3>What is compound interest?</h3>

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.

A = P(1 + r/n) $^{nt}$

P =5,500,000

r =4%= 0.004

n =4

t= 5 years.

Now,

A = P(1 + r/n) $^{nt}$

A = 5,500,000.00(1 + 0.04/4) $^{(4)(5)}$

A = 5,500,000.00(1 + 0.01) $^{20}$

A = $6,711,045.22

Hence, The total amount accrued is $6,711,045.22.

GUYS I NEED HELP ITS URGENT! WILL MARK BRAINLIEST!

Ad libitum [116K]

Answer:

k = 13 The smallest zero or root is x = -10

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

Work Shown:

note: you can write "x^2" to mean "x squared"

f(x) = x^2+3x-10

f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5

f(x+5) = (x^2+10x+25)+3(x+5)-10

f(x+5) = x^2+10x+25+3x+15-10

f(x+5) = x^2+13x+30

Compare this with x^2+kx+30 and we see that k = 13

Factor and solve the equation below

x^2+13x+30 = 0

(x+10)(x+3) = 0

x+10 = 0 or x+3 = 0

x = -10 or x = -3

The smallest zero is x = -10 as its the left-most value on a number line.

Hope this was Right
