Answer:

The very top one and the very bottom one.

Step-by-step explanation:

Since f(g(x)) means x goes into g and g goes into f..

If we plug in x+2 to the equation at the top, we would get 3/(x+2)^2

The bottom: (x+2)^2 gets plugged into x.. therefore, 3/(x+2)^2 will also occur.

According to the given plot, $f'(1)=2$ . Then the linear approximation to $f(x)$ at $x=1$ is

$L(x)=f(1)+f'(1)(x-1)=6+2(x-1)=2x+4$

Then

$f(0.95)\approx L(0.95)=5.9$

$f(1.05)\approx L(1.05)=6.1$

On the interval [0, 1], the plot of $f'(x)$ is positive, so $f(x)$ is an increasing function here. But we can see that $f'(x)$ is approaching 0. This means tangent lines to $f(x)$ have a positive slope, but the slopes are approaching 0 and are thus becoming less steep. This in turn means the tangent lines lie above the curve, so the approximations are greater than the actual values of $f(0.95)$ and $f(1.05)$ .

Find the value of 5x - 2y+ 3z when x = 7 , y = 11 and z = -1

Oksanka [162]

By replacing you get:

5*7-2*11+3*(-1) = 35-22-3= 10

so the answer is 10.

Jessica has $50 to spend on new clothes. The jacket that she wants to buy is $48.20. If the tax rate is 6% does Jessica have eno

Virty [35]

Answer:

Step-by-step explanation:

She has 50$. A jacket is on for 48.20$. The tax is 6% of the product you buy.

6% = 0.06

To find 6% you do:

0.06*48.20

Which is 2.892.

You ADD 2.892 to the price.

48.20+2.892=

51.092. Round it:

51.09 > 50.00

No, she does not have enough.
