You work for the National Weather Service and are asked to study the average daily temperatures in Anchorage, Alaska. You calculate the mean of the average daily temperatures for each month. You decide to place the information on a graph in which the date is the input and the temperature is the output. You also decide that January 1950 will correspond to the month 0 as indicated by the dot on the input scale.
On a coordinate plane, quadrants 1, 2, 3, and 4 are labeled. Month is on the x-axis and degrees Fahrenheit is on the y-axis.
Determine the quadrant in which you would plot the points that correspond to the following data:
The average daily temperature for July 1910 was 71 degreesF.

Find the general solution of the differential equation and check the result by differentiation. (Use C for the constant of integration) dy/dt = 27t^8 y = Find the general solution of the differential equation and check the result by differentiation. (Use C for the constant of integration.) dy/dx =8x^7/9 y =

Answers

Answer: [tex]y=Ce^(^3^t^{^9}^)[/tex]

Step-by-step explanation:

Beginning with the first differential equation:

[tex]\frac{dy}{dt} =27t^8y[/tex]

This differential equation is denoted as a separable differential equation due to us having the ability to separate the variables. Divide both sides by 'y' to get:

[tex]\frac{1}{y} \frac{dy}{dt} =27t^8[/tex]

Multiply both sides by 'dt' to get:

[tex]\frac{1}{y}dy =27t^8dt[/tex]

Integrate both sides. Both sides will produce an integration constant, but I will merge them together into a single integration constant on the right side:

[tex]\int\limits {\frac{1}{y} } \, dy=\int\limits {27t^8} \, dt[/tex]

[tex]ln(y)=27(\frac{1}{9} t^9)+C[/tex]

[tex]ln(y)=3t^9+C[/tex]

We want to cancel the natural log in order to isolate our function 'y'. We can do this by using 'e' since it is the inverse of the natural log:

[tex]e^l^n^(^y^)=e^(^3^t^{^9} ^+^C^)[/tex]

[tex]y=e^(^3^t^{^9} ^+^C^)[/tex]

We can take out the 'C' of the exponential using a rule of exponents. Addition in an exponent can be broken up into a product of their bases:

[tex]y=e^(^3^t^{^9}^)e^C[/tex]

The term e^C is just another constant, so with impunity, I can absorb everything into a single constant:

[tex]y=Ce^(^3^t^{^9}^)[/tex]

To check the answer by differentiation, you require the chain rule. Differentiating an exponential gives back the exponential, but you must multiply by the derivative of the inside. We get:

[tex]\frac{d}{dx} (y)=\frac{d}{dx}(Ce^(^3^t^{^9}^))[/tex]

[tex]\frac{dy}{dx} =(Ce^(^3^t^{^9}^))*\frac{d}{dx}(3t^9)[/tex]

[tex]\frac{dy}{dx} =(Ce^(^3^t^{^9}^))*27t^8[/tex]

Now check if the derivative equals the right side of the original differential equation:

[tex](Ce^(^3^t^{^9}^))*27t^8=27t^8*y(t)[/tex]

[tex]Ce^(^3^t^{^9}^)*27t^8=27t^8*Ce^(^3^t^{^9}^)[/tex]

QED

I unfortunately do not have enough room for your second question. It is the exact same type of differential equation as the one solved above. The only difference is the fractional exponent, which would make the problem slightly more involved. If you ask your second question again on a different problem, I'd be glad to help you solve it.

Answer:

  278°

Step-by-step explanation:

You want the measure of arc RSQ given inscribed angle RSQ has a measure of 41°.

Inscribed angle

An inscribed angle has half the measure of the arc it subtends. This means short arc RQ will have double the measure of angle RSQ:

  arc RQ = 2 × 41° = 82°

Long arc

The measure of long arc RSQ will complete the 360° circle:

  arc RSQ = 360° -arc RQ

  arc RSQ = 360° -82°

  arc RSQ = 278°

What is the value of x?

Answers

According to the given figures of triangle.. The value of x is 2.

Answer:

x = 3

Step-by-step explanation:

assuming the triangle is right.

using Pythagoras' identity

(x + 2)² = x² + 4²

x² + 4x + 4 = x² + 16 ( subtract x² from both sides )

4x + 4 = 16 ( subtract 4 from both sides )

4x = 12 ( divide both sides by 4 )

x = 3

Which shape has one less side and one less vertex than a trapezoid

Answers

Answer:

An Isosceles trapezoid

Step-by-step explanation:

The shape is triangle.

What is trapezoid?

In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides. If the remaining two sides are parallel, they are referred to as the legs (or lateral sides); if not, the trapezoid is a parallelogram, and there are two pairs of bases.

Given a trapezoid,

number of vertex trapezoid have = 4

one less vertex than trapezoid = 4 - 1 = 3

number of sides trapezoid has = 4

one less side than trapezoid = 4 - 1 = 3

the shape which has 3 sides and 3 vertex is triangle.

Hence the new shape is triangle.

The following instructions will work for most commonly used graphing calculators, but note that they might vary slightly based on calculator model. Now that you’ve learned how to use a graphing calculator to solve linear programming problems, solve the following problems.
Part A
Consider the given system
{2x+y ≤20
{3x+2y ≤30
{x,y ≥0
Graph the inequalities on your graphing calculator, and find the vertex points of this system
Part B
In part A, you obtained the vertex points of the given system. Test these vertex points in the objective function, f(z)=4x+6y using a graphing calculator. Find the maximum point.

Answers

Answer:

 A. see below for a graph

 B. f(x, y) = f(0, 15) = 90 is the maximum point

Step-by-step explanation:

A. See below for a graph. The vertices are those defined by the second inequality, since it is completely enclosed by the first inequality: (0, 0), (0, 15), (10, 0)

__

B. For f(x, y) = 4x +6y, we have ...

 f(0, 0) = 0

 f(0, 15) = 6·15 = 90 . . . . . the maximum point

 f(10, 0) = 4·10 = 40

_____

Comment on evaluating the objective function

I find it convenient to draw the line f(x, y) = 0 on the graph and then visually choose the vertex point that will put that line as far as possible from the origin. Here, the objective function is less steep than the feasible region boundary, so vertices toward the top of the graph will maximize the objective function.

The vertex points of this system are (0, 0), (0, 15) and (10, 0). And the maximum point of the system is 90.

What are systems of inequalities?

At least two linear inequalities in the same variables make up a system of linear inequality in two variables. The graph of a linear inequality is the graph of all solutions to the system, and the solution of a linear inequality is the ordered pair that resolves all inequalities in the system.

The given system:

2x+y ≤20

3x+2y ≤30

x, y ≥0

To find the vertex points,

first, we take inequalities in slope-intercept form.

y = 20 - 2x

And y = -3x/2 + 15

x, y ≥0

From that we interpreted the graph.

And the graph is given in the attached image.

A:

Check out the graph below. Given that the first inequality entirely encloses it, the vertices are those defined by the second inequality: (0, 0), (0, 15), (10, 0).

B:

We have objective function f(z) = 4x + 6y

To find the maximum point:

Substituting (0,0) to the function,

4x + 6y

= 4(0) + 6(0)

= 0

Substituting (0,15) to the function,

4x + 6y

= 4(0) + 6(15)

= 0 + 90

= 90

Substituting (10,0) to the function,

4x + 6y

= 4(10) + 6(0)

= 40 + 0

The maximum point is 90.

Therefore, (0, 0), (0, 15) and (10, 0) are the vertex of the system. And the maximum point is 90.

The scenario that could be modelled with an exponential function is when Tim adds $10 to his savings account each week.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

As we know that a continuous compounding function is an exponential function. Therefore, we need to find the situation where the principal amount is invested for an infinitely long time.

A.) Since the amount is invested and a certificate of deposit is taken the amount will be invested for a fixed period of time. Thus, this is not a continuous compound function.

B.) The amount put into the account and taken out of the account varies for each term. Thus, this is not a continuous function.

C.) As in Jaylon's account the money is reduced by $125 every month, therefore, at a certain point, it will become zero. Thus, this is not a continuous compound function.

D.) As Tim adds $10 to his saving account every month, and there is no time specified, also the account will be always positive. Thus, this is a continuous compound function.

Hence, the scenario that could be modelled with an exponential function is when Tim adds $10 to his savings account each week.

Most solvers will take I% to be the annual interest rate. (An HP-12C financial calculator uses the monthly interest rate.)
