Rewrite in simplest rational exponent form √x • 4√x. Show each step of your process.

Vikentia [17]

Step-by-step explanation:

$= \sqrt{x} .4 \sqrt{x}$

$= {x}^{ \frac{1}{2} } \times 4 {x}^{ \frac{1}{2} }$

$= 4 {x}^{ \frac{1}{2} + \frac{1}{2} }$

$= 4 {x}^{ \frac{2}{2} }$

$= 4 {x}^{1}$

$= 4x$

If G(s) is the inverse of S(g) , and G(2) =16 then s(16) = 2 true or false?

lina2011 [118]

If f(x) is the inverse of g(x) then if f(a)=b then g(b)=a

so if G(s) is the inverse of S(g) then if G(2)=16 then S(16)=2, true

yes, it's true

In a certain state, there are currently 5,902,060 acres of farmland. This area is decreasing at a rate of 4.3% every year. Selec

Luba_88 [7]

Answer:

y=5,902,060*(.957)^t

Step-by-step explanation:

Since the original amount would be decreasing and it's an exponential one, hence the "every year", we can determine that it's an exponential decay equation.

The exponential delay equation is y=A*(1-r)^t. The y is the remaining amount, A is the original amount, r is the rate in decimal form, and t is for years. "1-r" is for decreasing rates and "1+r" is for increasing rates.

First thing we need to do is turn the rate, 4.3%, from a percentage to a decimal. You can do this by moving the decimal two places to the right, which gives you 0.043.

Now plug the numbers into the equation.

y=5,902,060*(1-0.043)^t

Simplify what's inside the parenthesis and get your final equation.

y=5,902,060*(.957)^t

Write an expression in factored form that is equivalent to the given expression. 1/2x + 4 . can u also tell how you solved it ?

Rufina [12.5K]

2 ways: Easy and hard
Hard=A
Easy=B
A: 1/2x+4 work from there so we do fun stuff with it make something that can be simplified so 1/2x+4 times (2/2)=x+8 now square the whole thing and put the result in a square root thingie (x+8)^2=x^2+16x+64 $\sqrt{x^2+16x+64}$ multiply the whole thing by 4/4 and put $\sqrt{16} [\tex] on top so then 
[tex] \sqrt{x^2+16x+64}$ times $\frac{ \sqrt{16} }{4}$ = $\frac{\sqrt{(16)(x^2+16x+64)}}{4}$ = $\frac{ \sqrt{16x^2+256x+1024} }{4}$ to solve it, factor out the 16 in the square root and then square root 16 to get 4 then it will be (4 times square root of equation)/4=square root of equatio factor square root of equation and square root it and get x+8 divide by 2 to get 1/2x+4

B: 1/2x+4
put stuff that cancels out
1/2x+3x-3x+4+56-56
move them around
3 and 1/2x-3x+60-56
or
2x-3x+1 and 1/2x+30-20+30-36
then just add like terms to solve
