ted wants to buy a skateboard that costs $59.00, but is on sale for 30% off. How much money will he save

STatiana [176]

Answer:

$17.70

Step-by-step explanation:

Hi,

What you want to do is to find 30% of $59

First, you convert 30% into decimal form by dividing it by 100

30%=0.3

Next, you want to find 30% of 59, so what you do is you take the new decimal form and multiply it by 59

0.3×59=17.7

Ted is saving $17.70

Euler Bank advertises that it compounds interest continuously and that it will double your money in 20 yr. What is the annual in

Romashka [77]

To solve this problem you must apply the proccedure shown below:

1. You must apply the following formula:

$FV=(PV)(e^{it})$

Where $FV$ is the future value, $PV$ is the present value, $i$ is the interest rate and $t$ is the time in years.

2. You have that the bank will double your money in $20$ years. Therefore:

$FV=2PV$

3. Substitute values into the formula and solve for $i$ , as following:

$2PV=(PV)(e^{(i)(20)} \\ 2=e^{(i)(20)}$

4. By applying natural logarithm, you have:

$ln(2)=(i)(20) \\ i= \frac{ln(2)}{20} \\ i=0.0346$

$i=3.46$ %

The answer is: $3.46$ %

[SCREENSHOT INCLUDED] If f(x) = sqrt(2x+1) then f '(4) =

Sphinxa [80]

Using the definition,

$f'(4) = \displaystyle \lim_{x\to4} \frac{f(x)-f(4)}{x-4}$

The numerator in the difference quotient is

$f(x) - f(4) = \sqrt{2x+1} - \sqrt{2\cdot4+1} = \sqrt{2x+1}-3$

Multiply the numerator and denominator by the conjugate of this expression,

$\displaystyle \frac{\sqrt{2x+1}-3}{x-4} \cdot \dfrac{\sqrt{2x+1}+3}{\sqrt{2x+1}+3}$

The modified numerator reduces to a difference of squares,

$\displaystyle \frac{\left(\sqrt{2x+1}\right)^2-3^2}{(x-4)\left(\sqrt{2x+1}+3\right)}$

Simplify this to get

$\displaystyle \frac{2x+1-9}{(x-4)\left(\sqrt{2x+1}+3\right)} = \frac{2(x-4)}{(x-4)\left(\sqrt{2x+1}+3\right)}$

Since x is approaching 4, it never actually takes on the value of 4, so (x - 4)/(x - 4) reduces to 1. Then the limit is equivalent to

$f'(4) = \displaystyle \lim_{x\to4} \frac{f(x)-f(4)}{x-4} = \lim_{x\to4}\frac2{\sqrt{2x+1}+3}$

and the remaining limand is continuous at x = 4, so that

$f'(4) = \dfrac2{\sqrt{2\cdot4+1}+3} = \dfrac26 = \boxed{\dfrac13}$
