Simplify (5^x+2-5^x)/5^x×4

murzikaleks [220]

Answer:

6

Step-by-step explanation:

The given expression is,

$\frac{5^{x+2}-5^x }{5^x\times4}$

Now, we know that,

$a^{m+n} = a^m . a^n$

Then,

$5^{x+2}=5^x . 5^2$

So,

$\frac{5^{x+2}-5^x}{5^x\times4}=\frac{5^x.5^2-5^x}{5^x\times4}$

Now, taking $5^{x}$ common from the numerator of the given expression, then

$\frac{5^{x+2}-5^x}{5^x\times4}=\frac{5^x(5^2-1)}{5^x\times4}$

$\implies\frac{5^{x+2}-5^x }{5^x\times4}=\frac{5^2-1}{4}$

$\implies\frac{5^{x+2}-5^x}{5^x\times4}=\frac{5\times5-1}{4}=\frac{25-1}{4}$

$\implies\frac{5^{x+2}-5^x}{5^x\times4}=\frac{24}{4}=6$

So, the simplified form of the given expression gives the result 6.

Jenny bought a new car for $25,995. The value of the car depreciates by 16 percent each year. Which type of function could model

motikmotik

Answer: The answer is expensive the car is expensive. JK the answer is c. you can eliminate a and d because the 16 % a year increase so your left with c and b it's not b because of the price so your best answer would have to be c

Jacob throws an acorn into the air. It lands in front of him. The acorn's path is

Burka [1]

Answer:

hits the ground at x = -0.732, and x = 2.732
only the positive solution is reasonable

Step-by-step explanation:

The acorn will hit the ground where the value of x is such that y=0. We can find these values of x by solving the quadratic using any of several means.

__

<h3>graphing</h3>

The attachment shows a graphing calculator solution to the equation

-3x^2 + 6x + 6 = 0

The values of x are -0.732 and 2.732. The negative value is the point where the acorn would have originated from if its parabolic path were extrapolated backward in time. Only the positive horizontal distance is a reasonable solution.

__

<h3>completing the square</h3>

We can also solve the equation algebraically. One of the simplest methods is "completing the square."

-3x^2 +6x +6 = 0

x^2 -2x = 2 . . . . . . . . divide by -3 and add 2

x^2 -2x +1 = 2 +1 . . . . add 1 to complete the square

(x -1)^2 = 3 . . . . . . . . written as a square

x -1 = ±√3 . . . . . . . take the square root

x = 1 ±√3 . . . . . . . add 1; where the acorn hits the ground

The numerical values of these solutions are approximately ...

x ≈ {-0.732, 2.732}

The solutions to the equation say the acorn hits the ground at a distance of -0.732 behind Jacob, and at a distance of 2.732 in front of Jacob. The "behind" distance represents and extrapolation of the acorn's path backward in time before Jacob threw it. Only the positive solution is reasonable.
