If F(x) = f(g(x)), where f(−1) = 5, f ′(−1) = 3, f ′(5) = 3, g(5) = −1, and g ′(5) = 8, find F ′(5). F '(5) =

sattari [20]

Given:

$F(x)=f(g(x))$

where, $f(-1)=5,f'(-1)=3,f'(5)=3,g(5)=-1,g'(5)=8$ .

To find:

The value of $F'(5)$ .

Solution:

We have,

$F(x)=f(g(x))$

Differentiate with respect to x.

$F'(x)=\dfrac{d}{dx}f(g(x))$

Using chain rule, we get

$F'(x)=f'(g(x))g'(x)$

Now, put x=5.

$F'(5)=f'(g(5))g'(5)$

$F'(5)=f'(-1)\times 8$ $[\because g(5)=-1,g'(5)=8]$

$F'(5)=3\times 8$ $[\because f'(-1)=3]$

$F'(5)=24$

Therefore, the value of $F'(5)$ is 24.

Please explain how to do it I know the answer is 30%

Andrews [41]

To find this percentage, it will make it easier if it is worded differently. Put it "15 is what percent of 50?"

To find the percentage, simply divide 15 by 50 then multiply that quotient by 100.

15 / 50 = 0.3

0.3 x 100 = 30 = 30%

Answer:

25 dfferent ways

Step-by-step explanation:

The answer is 25 different ways because since there are students and thy line up behind each other you would do 5 times 5 which equals to 25.

Using Cramer’s Rule, what is the value of x in the system of linear equations below?

cluponka [151]

Answer:

x = 8 is the answer

Step-by-step explanation:

In order to find the solution of Equations using Cramer's rule

we shall find matrices

D= $\left[\begin{array}{ccc}5&-3\\1&-2\end{array}\right]$ =

$D_{1} = \left[\begin{array}{ccc}4&-3\\-16&-2\end{array}\right]$

l D l = Determinant formed by coefficient of variables

Here l D l = 5X(-2) - 1X(-3)= -10+3 = -7

l D1 l = Determinant formed by replacing first column In D by numbers on the right side of the equations

Here l D1 l = 4X(-2)- (-16)X(-3)= -8-48 = -56

here x is given by $\frac{l D1 l}{l D l}$

x = $\frac{-56}{-7}$

x = 8
