Given:

where,
.
To find:
The value of
.
Solution:
We have,

Differentiate with respect to x.

Using chain rule, we get

Now, put x=5.

![[\because g(5)=-1,g'(5)=8]](https://tex.z-dn.net/?f=%5B%5Cbecause%20g%285%29%3D-1%2Cg%27%285%29%3D8%5D)
![[\because f'(-1)=3]](https://tex.z-dn.net/?f=%5B%5Cbecause%20f%27%28-1%29%3D3%5D)

Therefore, the value of
is 24.
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.
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=
=
![D_{1} = \left[\begin{array}{ccc}4&-3\\-16&-2\end{array}\right]](https://tex.z-dn.net/?f=D_%7B1%7D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%26-3%5C%5C-16%26-2%5Cend%7Barray%7D%5Cright%5D)
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 
x = 
x = 8
Use an addition or subtraction formula to find the exact value of the expression, as demonstrated in example 1. tan(105°)
