Answer:

10% increase

Step-by-step explanation:

THe original quantity is 10

The new quantity is 11

We need to find the percentage increase.

Percentage increase is found by finding the increase (New - Old) and dividing the answer by the old value (original value). Then we multiply by 100 to get the percentage.

The change is: 11 - 10 = 1

Now, dividing by old, we get: 1/10

Now, multiplying by 100, we get the percentage: (1/10) * 100 = 10%

So, from 10 to 11, there is a 10% increase

What is the sale price to the nearest cent? $239 television; 10% discount

miv72 [106K]

Answer:

The sale price will be: $215.10

Step-by-step explanation:

We know that:

Sale price = Regular price × (100% - Discount %)

= Regular price × (100% - 10%)

= 239 × 90%

= 239 × 0.9

= 215. 10 $

Therefore, the sale price will be: $215. 10

If f'(0) = 5 and F(x) = f(3x), what is F'(0)?

Llana [10]

Answer:

$\displaystyle F'(0) = 15$

Step-by-step explanation:

We are given that:

$f'(0) = 5 \text{ and } F(x) = f(3x)$

And we want to find F'(0).

First, find F(x):

$\displaystyle F'(x) = \frac{d}{dx}\left[ f(3x)]$

From the chain rule:

$\displaystyle \begin{aligned} F'(x) &= f'(3x) \cdot \frac{d}{dx} \left[ 3x\right] \\ \\ &= 3f'(3x)\end{aligned}$

Then:

$\displaystyle \begin{aligned} F'(0) & = 3f'(3(0)) \\ \\ & = 3f'(0) \\ \\ & = 3(5) \\ \\ & = 15\end{aligned}$

In conclusion, F'(0) = 15.

Find the volume of a right circular cone that has a height of 17.7 cm and a base with a diameter of 15.8 cm. Round your answer t

Lelu [443]

Answer:

$1156.8cm^3$

Step-by-step explanation:

The volume of a cone is given as:

$V =\frac{1}{3} \pi r^2h$

where r = radius

h = height of cone

The height of the cone is 17.7 cm and its base radius is 7.9 cm (diameter is 15.8 cm).

Its volume is:

$V = \frac{1}{3} * \pi = 7.9^2 * 17.7\\ \\V = 1156.8cm^3$
