The statements that are true regarding the temperature include:

1. At noon, the temperature is - 9 1/2°F.

2. The temperature at 5pm is - 15 3/4°F.

3. The change in temperature from noon to 5pm is - 6 1/4°F.

From the information, the temperature at 6A.M is -14°D and the temperature increases at an average of 3/4°F each hour until noon. Then it drops at 1 1/4°F until 5P.M.

The temperature at noon will be:

= -14 + (3/4 × 6)

= -14 + 4.5

= -9.5°F

The temperature at 5pm will be:

= -9.5 - (1 1/4 × 5)

= -9.5 - 6.25

= -15.75

The total change in temperature will be:

= Ending temperature - Starting temperature

= -15.75°F - (-14°F)

= 1.75°F

The temperature change from noon to 5 pm will be:

= -15.75 - (-9.5)

= -6.25 = 6 1/4°F

It takes four (4) comedy routines to hear 360 jokes

A proportion can be defined as an equation which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.

By applying direct proportion, we have:

1 minute = 3 jokes

X minutes = 360 jokes

Cross-multiplying, we have:

3X = 360

X = 360/3

X = 120 minutes

The degree of the polynomial is even.

Algebraic expressions called polynomials include indeterminates and constants. Polynomials can be considered a particular type of mathematics. In practically all areas of mathematics, including calculus, they are used to express numbers. They are also regarded as being crucial in several areas of mathematics. Examples of polynomials include 2x + 9 and [tex]x^{2}[/tex] + 3x + 11. The "=" sign is absent from all of these samples, as you may have observed.

The polynomial's degree is even since the final behavior is the same in both directions (for -x and for +x, y→∞).

b) The factory should operate for 10 hours to have a production of 4500 units.

c) The graph for the first 20 hours of the function is given at the end of the answer.

A linear function, in slope-intercept format, is modeled according to the following rule:

y = mx + b

In which:

For the given linear relationship, we have two points, as follows:

(5,2000) and (8,3500).

The slope is given by change in y divided by change in x, hence:

m = 1500/3 = 500.

Then:

y = 500t + b.

When t = 5, y = 2000, hence we solve for the intercept as follows:

2000 = 500(5) + b

b = -500.

Then the function is:

y = 500t - 500.

For 4500 units, the time is found as follows:

4500 = 500t - 500

500t = 5000.

t = 5000/500

t = 10 hours.

Answer:

  the slope is 3/4

  the y-intercept is 4

Step-by-step explanation:

You want the slope and y-intercept of the line defined by the equation 3x -4y = -16.

The values of interest can be found easily from the slope-intercept form of the equation of the line. Solving for y puts the equation in that form.

  3x -4y = -16 . . . . . . given

  -4y = -3x -16 . . . . . subtract 3x

  y = 3/4x +4 . . . . . . divide by -4

Compare this to the slope-intercept form equation:

  y = mx + b . . . . . . . line with slope m and y-intercept b

We see that ...

  m = 3/4, b = 4

  The slope is 3/4

  The y-intercept is 4

y = mx + b

In which:

For this problem, the function is:

y = 2/3x + 1.

Then, form item a, we have that:

For item b, the y-intercept of b = 1 means that the function crosses the y-axis at b = 1.

For item c, we have to consider that the slope is of 2/3, meaning that when y increases by 2, x increases by 3. Point (0,1) is on the graph of the function, hence point (3,3) will also be, as x increases by 3 from 0 to 3 and y increases by 2 from 1 to 3.

An equation of the function in standard form for the given table of values is equal to -2x² - 7x - 6 = 0.

In Mathematics, the standard form of a quadratic equation is given by;

y = f(x) = ax² + bx + c = 0

In order to write an equation of the quadratic function in standard form, we would formulate a system of equations from the data provided in the table above as follows:

-6 = a(-3)² + b(-3) + c  ⇒ -6 = 9a - 3b + c      .......equation 1.

0 = a(-2)² + b(-2) + c  ⇒   0 = 4a - 2b + c      .......equation 2.

-2 = a(-1)² + b(-1) + c  ⇒   -2 = a - b + c          .......equation 3.

From equation. 2, we derive:

c = -4a + 2b   .....equation 4.

Substituting equation 4 into equation 1 and 3, we derive the following equations:

-2 = a - b - 4a + 2b          ⇒ -2 = -3a + b

-6 = 9a - 3b - 4a + 2b     ⇒ -6 = 5a - b

By using the elimination method, the value of a is given by:

[-2 + (-6) = (-3a + 5a) + (b + (-b)]

-2 - 6 = -3a + 5a + b - b

-8 = 2a

a = -4

Next, we would determine the value of b as follows:

-2 = -3a + b

b = -2 + 3a

b = -2 + 3(-4)

b = -2 - 12

b = -14

For the value of c, we have:

c = -4a + 2b

c = -4(-4) + 2(-14)

c = 16 - 28

c = -12.

Substituting the respective values of a, b and c into the standard form of a quadratic equation:

ax² + bx + c = 0

-4x² - 14x - 12 = 0

Dividing all through by 2, we have the following quadratic function:

Answer:

  20 mi/h

Step-by-step explanation:

You want the speed of separation after 3 hours between two cars that started from the same point. One is moving at 16 mi/h south, the other is moving at 12 mi/h west.

Since both cars started from the same point, the speed of separation is the magnitude of the difference between the respective velocity vectors. A graphical representation of the velocity vectors shows them to be the legs of a right triangle. Their difference is the length of the hypotenuse, which can be found using the Pythagorean theorem.

  s = √(16² +12²) = √(256 +144) = √400

  s = 20

The speed of separation is a constant 20 mi/h.

__

Additional comment

If the cars did not start at the same point, then the speed of separation would be changing with time. It could be found using the derivative of the distance between the cars, or by considering the car speeds in the direction each car is from the other at the time of interest.

We note that the problem here makes use of a 3-4-5 right triangle, with a multiplier of 4 mph.
