First, factor the (3y-4) and group the remaining terms
y²(3y-4) +7 (3y-4)
(y²+7)(3y-4)
I hope this helps (:

Dur, so notice we can reverse distribute
ab+ac=a(b+c)

in this case, a=(3y-4)
so
(3y-4)y²+(3y-4)7=(3y-4)(y²+7)

A student randomly draws a card from a standard deck and checks to see if it is his favorite suit he then returned to card to th

tensa zangetsu [6.8K]

Answer:

The binomial probability formula can not be used for this experiment because it does not state the number of times he expects to draw his favorite suit.

Step-by-step explanation:

The binomial probability formula is expressed as follows:

P (k success in n trials) = $\left \{ {{n \atop k} \right.$ $p^{k}$ $q^{n-k}$

n = number of trials, k = number of successes, n-k = number of failures, p = probability of success in one trial and q = 1 - p = probability of failure in one trial.

In the given problem, all of the variables are known except for 'k', the amount of times that the student predicts he will draw his favorite suit.

A new DVD is available for sale in a store one week after its release. The cumulative revenue, $R, from sales of the DVD in this

AnnyKZ [126]

Solution :

It is given that :

$f'(t) = (350 \ln t)'$

$=350(\ln t)'$

$=\frac{350}{t}$

So, $f(5)=350 \ln (5) \approx 563$

$f'(5) = \frac{350}{5}$

$=70$

The relative change is then,

$\frac{f'(5)}{f(5)}=\frac{70}{350\ \ln(5)}$

$=\frac{1}{5\ \ln(5)}$

$\approx 0.12$

$=12\%$

This means that after 5 weeks, the revenue from the DVD sales in $563 with a rate of change of $70 per week and the increasing at a continuous rate of 12% per week.

F(x) = x°-9x

laila [671]

F(x)=x^3-9x
and
g(x)=x^2-2x-3

so you just need to divide f(x) by g(x)

Therefore:

f(x)/g(x) = (x^3-9x) / (x^2-2x-3)

and of course you need to factor these two function to see if some factor would cancel another

x^3-9x = x(x^2-9)=x(x-3)(x+3)
and
x^2-2x-3 = (x-3)(x+1)
