PLEASE HELP 10 POINTS

Mathematics
1 answer:
VARVARA [1.3K]4 years ago
8 0

Answer:

10.4%

Step-by-step explanation:

The original price = $2.40

Price after drop = $2.15

The drop = $2.40 - $2.15 = $0.25

Percentage decrease = \frac{decrease}{original-price} × 100

i.e Percentage decrease = \frac{0.25}{2.40} × 100 = 10.41666667%

Or 10.4% (Rounded up to nearest tenth of a percent).

Substitute u=\ln x, so that \mathrm du=\dfrac{\mathrm dx}x. The integral is then equivalent to

\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\int\frac{\mathrm du}{u^p}=\begin{cases}\dfrac{u^{p+1}}{p+1}+C&\text{for }p\neq1\\\\\ln|u|+C&\text{for }p=1\end{cases}

Then transforming back to x gives

\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\begin{cases}\dfrac{\ln^{p+1}x}{p+1}+C&\text{for }p\neq1\\\\\ln|\ln x|+C&\text{for }p=1\end{cases}

Round 829 to the nearest tenth
Ainat [17]
829 rounded to the nearest tenth is 830

If the 9 would be a 4 or lower, then it would be 820, but in this case, it's a number larger than 5, so it would be 830.

Elenna [48]
Write as a function equation: where f(x) is the same as "y"

f(x) = 5 + 1x   ------  y = 1x + 5

Use:  y = mx + b  (Where m = slope and b is y intercept)

Slope is 1 and y intercept is +5 

Remember slope is rise over run so 1 can be written as 1 / 1 and interpreted as rise 1 and run 1 both in the positive direction.
