Step-by-step explanation:

Given:

Complementary angle = 68'

Angle measure = 90' - 68' = 22'

Supplementary angle = 180' - 22' = 158'

Angle classification = Acute angle

Given:

Supplementary angle = 161'

Angle measure = 180' - 161' = 19'

Complementary angle = 90' - 19' = 71'

Angle classification = Acute angle

Given:

Angle measure = 136'

Angle classification = Obtuse angle

Complementary angle = 136' - 90' = 46'

Supplementary angle = 180' - 136' = 44'

Find the local extreme values of the function f(x, y) = xy - x2 - y2 - 3x - 3y + 12
aev [14]
f(x,y)=xy-x^2-y^2-3x-3y+12

First compute the first-order partial derivatives and find the critical points.


f_x=y-2x-3
f_y=x-2y-3

Both first order derivatives vanish at (x,y)=(-3,-3).


Computing the Hessian, we get

\mathbf H(x,y)=\begin{bmatrix}f_{xx}&f_{xy}\\f_{yx}&f_{yy}\end{bmatrix}=\begin{bmatrix}-2&1\\1&-2\end{bmatrix}

We have \det\mathbf H(x,y)=3>0, which means (-3,-3) is an extremum of f(x,y). Since f_{xx}(-3,-3)=-2, this extremum is a local maximum of f(x,y) with a value of 21.

The city of Townsville has a population of 2 million in 2002, which is growing at 6% per year.A) Write a recursive formula for t
inna [77]

Given:

Population in 2002 is 2 million and is growing at 6%per year.

A)

Recursive formula:

P_n=P_{n-1}(1+\frac{6}{100})P_n=P_{n-1}(\frac{100+6}{100})P_n=P_{n-1}(\frac{53}{50})P_0=2.2\text{ }P_n=P_{n-1}(1.06)

B)

P_1=P_0(1.06)P_2=P_1(1.06)P_2=P_0(1.06)_{}(1.06)P_2=2.2(1.06)^2_{}P_n=2.2(1.06)^n_{}

C)

n=2011-2002

n=9

No\text{ of people in 2011=}2.2(1.06)^9No\text{ of people in 2011=}3.7\text{ millon}

Does anyone know the answer to this??
Reptile [31]
The first answer and the last one

Plug in each number into their designated spots.
Example with (0,5)

0 goes into x and 5 goes into the y variable and this is the equation now:

2*0 +4*5=20

0 times 2 = 0 and 4*5=20
So that is one of the correct answers.

Repeat the process and you find that the last option is also correct.
