john scored 15 points his first game. In his last game he scored 20 points. What was his percent of increase?

iVinArrow [24]

$\huge\mathrm{ \it{Answer࿐}}$

Increase = 20 - 15 = 5 points

$\boxed{ \% \: increase \: = \frac{5}{15} \times 100 }$

$\% \: \:increase = \frac{100}{3}$

$\% \: \:increase = 33.33$

What is the value of \dfrac{d}{dx}\left(\dfrac{2x+3}{3x^2-4}\right) dx d ( 3x 2 −4 2x+3 )start fraction, d, divided by, d, x

stellarik [79]

Answer:

Step-by-step explanation:

We are asked to find the value of expression $\frac{d}{dx}(\frac{2x+3}{3x^2-4})$ at $x=-1$ .

First of all, we will find the derivative of the given expression using "Quotient Rule of Derivatives" as shown below:

$(\frac{f(x)}{g(x)})'=\frac{f'(x)\cdot g(x)-f(x)\cdot g'(x)}{(g(x))^2}$

$\frac{d}{dx}(\frac{2x+3}{3x^2-4})$

$\frac{\frac{d}{dx}(2x+3)*(3x^2-4)-(2x+3)*\frac{d}{dx}(3x^2-4)}{(3x^2-4)^2}$

$\frac{2*(3x^2-4)-(2x+3)*(6x)}{(3x^2-4)^2}$

$\frac{6x^2-8-12x^2-18x}{(3x^2-4)^2}$

$\frac{-6x^2-18x-8}{(3x^2-4)^2}$

Therefore, our required derivative is $\frac{-6x^2-18x-8}{(3x^2-4)^2}$ .

Now, we will substitute $x=-1$ in our derivative to find the required value as:

$\frac{-6(-1)^2-18(-1)-8}{(3(-1)^2-4)^2}$

$\frac{-6(1)+18-8}{(3(1)-4)^2}$

$\frac{-6+18-8}{(3-4)^2}$

$\frac{4}{(-1)^2}$

$\frac{4}{1}$

$4$

Therefore, the value of expression $\frac{d}{dx}(\frac{2x+3}{3x^2-4})$ at $x=-1$ is 4.

During a football game the ball is placed 20 yards and 2 feet from the goal line how many feet from the goal line is the footbal

qaws [65]

Answer:62 feet

1 yard=3 feet

Cooper is opening an online savings account to hold his $19,000 emergency fund. The online account pays 1.6 interest compounded

astraxan [27]

Using compound interest, it is found that $20,581.36 will be in the account in 5 years.

<h3>What is compound interest?</h3>

The amount of money earned, in compound interest, after t years, is given by:

$A(t) = P\left(1 + \frac{r}{n}\right)^{nt}$

In which:

A(t) is the amount of money after t years.

P is the principal(the initial sum of money).

r is the interest rate(as a decimal value).

n is the number of times that interest is compounded per year.

t is the time in years for which the money is invested or borrowed.

In this problem:

The initial deposit is of P = 19000.

The rate is of r = 0.016.

Monthly compounding, hence n = 12.

5 years, hence t = 5.

Then:

$A(t) = P\left(1 + \frac{r}{n}\right)^{nt}$

$A(5) = 19000\left(1 + \frac{0.016}{12}\right)^{12(5)}$

$A(5) = 20581.36$

$20,581.36 will be in the account in 5 years.
