Find f(x) and g(x) so that the function can be described as y = f(g(x)). y = 4/x^2+9

dlinn [17]

I'm assuming all of (x^2+9) is in the denominator. If that assumption is correct, then,

One possible answer is $f(x) = \frac{4}{x}, \ \ g(x) = x^2+9$

Another possible answer is $f(x) = \frac{4}{x+9}, \ \ g(x) = x^2$

There are many ways to do this. The idea is that when we have f( g(x) ), we basically replace every x in f(x) with g(x)

So in the first example above, we would have

$f(x) = \frac{4}{x}\\\\f( g(x) ) = \frac{4}{g(x)}\\\\f( g(x) ) = \frac{4}{x^2+9}$

In that third step, g(x) was replaced with x^2+9 since g(x) = x^2+9.

Similar steps will happen with the second example as well (when g(x) = x^2)

Below is the solution:

A(final)=16cm^2 ds/dT=6 da/dT=?

A=(s)^2 A=16cm^2 , s=sqrt(A) , s=sqrt(16) , s=4cm 

da/dT=2(s)(6cm/sec) , da/dT=12cm/sec(s) , da/dT=12cm/sec (4cm)

Answer should be da/dT=48cm^2/sec

A researcher conducted a paired sample t-test to determine if advertisements were viewed more in the morning (before noon) or in

Natalija [7]

Answer:

b. No, there was no difference between Morning (M= 32), and Evening (M=40.625), (t [7] = 1.15, p > .05).

Step-by-step explanation:

The critical value for one tailed test is t ∝(7) > 1.895

A one tailed test is performed to test the claim that advertisements were viewed more in the morning (before noon) or in the evening (after 5pm)

The null and alternative hypotheses are

H0: μm = μe vs Ha μm > μe

where μm is the mean of the morning and μe is the mean of evening.

The calculated value of t = -1.152587077 which is less than the critical region hence the null hypothesis cannot be rejected .

P(T<=t) one-tail 0.143458126 > 0.05

If two tailed test is performed the critical region is t Critical two-tail 2.364624252

and the calculated t value is -1.152587077 which again does not lie in the critical region .

Hence μm = μe or μm ≤ μe

P(T<=t) two-tail 0.286916252 > 0.025

Therefore

b. No, there was no difference between Morning (M= 32), and Evening (M=40.625), (t [7] = 1.15, p > .05).

Option b gives the best answer.

What is 25% of 24? What is 15% of 60? 9 is what percent of 72

JulsSmile [24]

Answer:

6

9

6.48

Step-by-step explanation:

this is the easiest way to solve for percentage:

$\frac{part}{whole} =\frac{part}{whole}$ Where all the percents (except 100) would go in part

and the whole number would go in whole

$\frac{25}{100} =\frac{?}{24}$ Then multiply 24 × 25 ÷ 100 = 6

$\frac{15}{100} =\frac{?}{60}$ Multiply 60 by 25 then divided by 100 = 9

Then for the last one 9 is what percent of 72

all we have to do is multiply 9 and then convert 72 into a decimal (0.72)

Then 9 × 0.72 = 6.48
