Answer:

3 71/99.

Step-by-step explanation:

0.71.. * 100 = 71.71..

0,71.. * 1 = 00.71.. Subtract:

0.71 * 99 = 71

So 3.71.. = 3 71/99.

Factor completly 4x^2 +8x -5

DaniilM [7]

∑ Hey, jillianwagler ⊃

Answer:

$\left(2x-1\right)\left(2x+5\right)$

Step-by-step explanation:

║Given info║:

Factor completely: $4x^2 +8x -5$

Solution~:

Breaking the expression~: $\left(4x^2-2x\right)+\left(10x-5\right)$

Factor out 2x from 4x² -2x : 2x(2x-1)

Factor out 5 from 10x - 5 : 5(2x - 1)

Put together: $=2x\left(2x-1\right)+5\left(2x-1\right)$

Factor out 2x - 1: $=\left(2x-1\right)\left(2x+5\right)$

What are the domain range of f(x)= 1/5 power of x

Snowcat [4.5K]

Answer:

Domain: all real numbers

Range: all real numbers

Step-by-step explanation:

I'm assuming you mean the function $f(x)=x^{\frac{1}{5}}$ . That's usually written

f(x) = x^(1/5) with the ^ meaning "to the power of..." and the fraction exponent in parentheses so as not to be confused with x^1/5 which could mean x to the first power, divided by 5.

Fractional exponents are used to indicate roots. In this case, x is being raised to the 1/5 power, so this is the fifth root of x, written $\sqrt[5]{x}$ . The 5 is called the root index.

For odd roots, like this one, the domain is all real numbers--x can be any number at all. So the domain is all real numbers.

The range is also all real numbers. Attached is a graph of this function. It might not look like it, but the graph rises to the right to any height. The larger x gets, the larger the 5th root gets. A similar thing happens on the left--the smaller x gets, the smaller the 5th root gets.

EDIT: see the comment. For the function $f(x)=(1/5)^x$ , the domain is all real numbers. The range is positive real numbers. I'll attach a graph!
