Answer:

$48.0

Step-by-step explanation:

Given data

Total cost of DVDs= $24.99+ $19.99

=$44.98

Let us compute the amount of the tax 6.75%

= 6.75/100* 44.98

=0.0675* 44.98

=$3.03615

The total cost including the tax is

=44.98+3.03615

=$48.0

If 6 = m/8, <br> What does "m" equal?

Ostrovityanka [42]

Answer:

Step-by-step explanation:

Hello :)

To solve this question, we need to isolate the variable m.

6=m/8

To get rid of 8, we can multiply 8 both sides to get rid of it.

8x6=m

48=m

If f(x)=2x^2+(1000/x), find the average rate of change of f(x) from x=a to x=a+h.

galina1969 [7]

Answer:

$\frac{\frac{1000}{x+h}-\frac{1000}{x}}{h}$ is your average rate of change,

Step-by-step explanation:

average rate of change is

$\frac{f(a+h)-f(a)}{a+h-a}$ , by slope formula

simplify this to get $\frac{f(a+h)-f(a)}{h}$ , which is the definition of the derivative as h goes to 0

$\lim_{h \to 0} \frac{f(a+h)-f(a)}{h}$

since you defined x=a, we can substitute a for x and vice versa to find our derivative.

$\lim_{h \to 0} \frac{(2x^2+\frac{1000}{x+h})-(2x^2+\frac{1000}{x})}{h}$

simplifying

$\lim_{h \to 0} \frac{\frac{1000}{x+h}-\frac{1000}{x}}{h}$ (your average rate of change)

PLEASEEE HELP I HAVE NO IDEA ITS DUE IN 10 MIN

hammer [34]

To find out how many students voluteered, simply add the fractions:

$\dfrac{1}{3}+\dfrac{1}{4}+\dfrac{2}{6}$

Remember that 2/6=1/3, so the sum is actually

$\dfrac{1}{3}+\dfrac{1}{4}+\dfrac{1}{3}$

We can sum the first and last terms immediately:

$\dfrac{2}{3}+\dfrac{1}{4}$

And finally, we can change both fractions so that they have the same denominator:

$\dfrac{2}{3}+\dfrac{1}{4} = \dfrac{8}{12}+\dfrac{3}{12} = \dfrac{11}{12}$
