Charlie was carrying around the steps to solve Square root of 6x plus 4 = 8. On his way through the Math Factory, Charlie droppe
fomenos

Answer: Order will be F,D,C and Fourth Option is correct and  x = 10

Step-by-step explanation:

Since we have given that

\sqrt{6x+4}=8

We first transpose the square root to the right , so it becomes square of 8,i.e.

6x+4=8^2\\\\6x+4=64

Now, transpose 4 to the right so it will get subtract from 64 i.e.

6x=64-4\\\\6x=60

Since 6 is multiplied to x on tranposing it will get divided by 60 i.e.

x=\frac{60}{6}\\\\x=10

Hence, on simplification, we get x=10.

Hence , the order is F,D,C.

The rabbit population of Springfield, Ohio was 144,000 in 2016. It is expected to decrease by about 7.2% per year. Write an expo
xeze [42]
<h2>Hello!</h2>

The answer is:

In 2036 there will be a population of 32309 rabbits.

<h2>Why?</h2>

We can calculate the exponential decay using the following function:

P(t)=StartAmount*(1-\frac{percent}{100})^{t}

Where,

Start Amount, is the starting value or amount.

Percent, is the decay rate.

t, is the time elapsed.

We are given:

StartAmount=144,000\\x=7.2(percent)\\t=2036-2016=20years

Now, substituting it into the equation, we have:

P(t)=StartAmount(1-\frac{percent}{100})^{t}

P(t)=144000*(1-\frac{7.2}{100})^{20}

P(t)=144000*(1-0.072)^{20}

P(t)=144000*(0.928)^{20}

P(t)=144000*(0.928)^{20}

P(t)=144000*0.861=32308.888=32309

Hence, we have that in 2036 the population of rabbis will be 32309 rabbits.

Have a nice day!
