1/4 to 1/2

erastovalidia [21]

Given:

$\dfrac{1}{4}\text{ to }\dfrac{1}{2}$

To find:

The percent of change, round to the nearest 10th of a percent.

Solution:

We have,

Initial value = $\dfrac{1}{4}$

New value = $\dfrac{1}{2}$

We know that, the percentage change is

$\%\text{ change}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100$

Putting the given values, we get

$\%\text{ change}=\dfrac{\dfrac{1}{2}-\dfrac{1}{4}}{\dfrac{1}{4}}\times 100$

$\%\text{ change}=\dfrac{\dfrac{2-1}{4}}{\dfrac{1}{4}}\times 100$

$\%\text{ change}=\dfrac{\dfrac{1}{4}}{\dfrac{1}{4}}\times 100$

$\%\text{ change}=1\times 100$

$\%\text{ change}=100\%$

Here, the % change is positive, it represents the percent increase.

Therefore, the percent of change is 100% of increase.

22 less than the quotient of an unknown number and 35 is -25

Nataly [62]

(x/35) - 22 = -25
“Less than” meaning it is the number being subtracted by, therefore goes behind the quotient of x, being the unknown number, and 35. “is” typically means equal.

Need help with exponential functions quick <br> 30 points

lisov135 [29]

Answer:

Since the independent variable x is not the exponent, $y = - 7 x^{8}$ does not represent an exponential function.

Step-by-step explanation:

The general expression of an exponential function is $f(x) = a^{x}$ , where a > 0 and a ≠ 1

Now the given function is $y = - 7 x^{8}$ ..... (1)

So, we can say that the function f(x) = y is not an exponential function as x is not in power of any constant.

Therefore, since the independent variable x is not the exponent, $y = - 7 x^{8}$ does not represent an exponential function. (Answer)
