Answer:

8b) 2x+\sqrt{3}x

8c) \frac{x-3\sqrt{x} +2 }{x-4}

Step-by-step explanation:

8b)

Multiply the top and bottom by 2+\sqrt{3} to rationalize this fraction

\frac{x}{2-\sqrt{3} } * \frac{2+\sqrt{3} }{2+\sqrt{3} }

Simplify the product

\frac{x(2+\sqrt{3}) }{1}

Distribute x through the parenthesis

2x+\sqrt{3}x

8c)

Multiply the top and bottom by \sqrt{x}-2 to rationalize this fraction

\frac{(\sqrt{x}-1)*(\sqrt{x}-2) }{(\sqrt{x}+2)*(\sqrt{x}-2) }

Simplify the product

\frac{x-2\sqrt{x}-\sqrt{x}+2  }{x-4}

Collect like terms

\frac{x-3\sqrt{x} +2 }{x-4}

Enter the explicit rule for the geometric sequence.<br><br> 9,6,4,83,…
soldier1979 [14.2K]

Answer:

a_n = 2^(n - 1) 3^(3 - n)


Step-by-step explanation:

9,6,4,8/3,…

a1 = 3^2

a2 = 3 * 2

a3 = 2^2

As we can see, the 3 ^x is decreasing and the 2^ y is increasing

We need to play with the exponent in terms of n

Lets look at the exponent for the base of 2

a1 = 3^2  2^0

a2 = 3^1   2^1

a3 =    3^ 0 2^2

an =   3^      2^(n-1)

I picked n-1  because that is where it starts  0

 n = 1   (1-1) =0

  n=2   (2-1) =1

  n=3  (3-1) =2

Now we need to figure out the exponent for the 3 base

I will pick (3-n)

n =1  (3-1) =2

n =2  (3-2) =1

n=3    (3-3) =0

Find the slope of the line on the graph
Oksana_A [137]
The slope is 3/1, which can be simplified to 3. Find it by traveling up 3 points and over 1 point form one intersection point to the next.

HELPPP The number of members in the Triathlon Club was 36 in 2001 and has increased by 20% each year. Which exponential growth m
levacccp [35]

Answer:

C. y=36(1.2)t

Step-by-step explanation:

The number of members in the Club in t years after 2001 is given by an equation in the following format:

y = y(0)(1+r)^{t}

In which y(0) is the number of members in 2001 and r is the growth rate, as a decimal.

The number of members in the Triathlon Club was 36 in 2001 and has increased by 20% each year.

This means that y(0) = 36, r = 0.2

So

y = y(0)(1+r)^{t}

y = 36(1+0.2)^{t}

y = 36(1.2)^{t}

The correct answer is C.

Can someone help me with this i have been trying for hours and i actually got the wrong answer so can you help me understand by
kap26 [50]

Answer:

C

Step-by-step explanation:

We are given that FGH is a triangle, which means that...

Angle F + Angle G + Angle H = 180

Start by substituting the given angle measurements into the equation:

4x+2+13x-7+3x+5=180

Combine like terms

20x=180

Divide both sides by 20 to isolate x

x=9

Plug 9 back in for x to solve for each angle

Angle F = 4(9)+2=36+2=38

Angle G = 13(9)-7=117-7=110

Angle H = 3(9)+5=27+5=32
