Answer:

(A ) Oldies

Step-by-step explanation:

Goodies

First, we determine the revolution rate per minute of the Goodies.

Revolution rate per minute [tex]=$Number of Revolutions \div $Number of Minutes[/tex]

[tex]=\dfrac{135}{3} =\dfrac{180}{4} =\dfrac{225}{5}=45$ revolutions per minute[/tex]

Since the oldies have a rate of 78 revolutions per minute;

78 rpm. >45 rpm.

We therefore conclude that the Oldies has a greater rate of revolutions per minute.

The correct option is A.

Answer:

y=jx+4

Step-by-step explanation:

The equtaion for slope intercept is y=mx+b. We know that the m is slope and for our problem, the slope is j. The x is always added to the equation. Also the b is the y intercept. For this problem, the y intercept is 4.

Answer:

third option

Step-by-step explanation:

A graph representing direct variation must pass through the origin.

The graph through (- 4, 3) and (4, 3) is a horizontal line and does not go through the origin.

Thus the line does not represent a direct variation because it does not go through the origin.

Answer: 31.41 square units

Step-by-step explanation:

Hi, to answer this question we have t apply the next formula:

Lateral area of a right cone = π x slant height x radius

Radius = diameter /2 = 4 /2 = 2 units

To find the slant height:

Since the altitude, slant and radius forms a right triangle we have to apply the Pythagorean Theorem:  

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (in this case the slant) and a and b are the other sides.  

Replacing with the values given:  

c^2 = 4^2 + 3^2  

c^2 = 16 +9

c^2 = 25

c = √25

c = 5 units (slant)

Back with the Lateral area formula:

Lateral area of a right cone (LA) = π x slant height x radius

LA = π x 5 x 2 = 31.41 square units

Answer:

9 degrees Celsius

Step-by-step explanation:

I graphed the function on the graph below to find the maximum of the parabola. The maximum is at (9,200), which means at 9 degrees Celsius, there are 200,000 fish.

The temperature at which there will be maximum number of fishes is given by the point (9, 200), is it is 9 degrees.

Given data:

To find the temperature that will result in the maximum number of fish, determine the x-value (temperature) at the vertex of the quadratic function.

The given function is P(x) = -2(x - 9)² + 200, where P(x) represents the fish population in thousands and x represents the water's temperature.

The general form of a quadratic function is y = a(x - h)² + k, where (h, k) represents the vertex of the parabola.

The vertex form of the function is P(x) = -2(x - 9)² + 200.

Comparing this to the general form, the vertex of the parabola is at the point (9, 200).

Hence, the temperature that will result in the maximum number of fish is 9 degrees (the x-value of the vertex).

Answer:

y = 2x + 54

Step-by-step explanation:

slope of equation:

(y2-y1)/(x2-x1)

= (72-58)/(9-2)

= 14/7

= 2

y = 2x + b

58 = 2(2) + b

58 = 4 + b

b = 54

Answer:

slope = 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, - 5) and (x₂, y₂ ) = (- 3, - 6)

m = [tex]\frac{-6-(-5)}{-3-(-2)}[/tex] = [tex]\frac{-6+5}{-3+2}[/tex] = [tex]\frac{-1}{-1}[/tex] = 1

The table of ordered pair is an illustration of a linear function.

The value of y when x = 8 is -8

From the table (see attachment), we have the following highlights

When x = 10, y = -12

So, when x decreases by 2 (to 8), the value of y will increase by 4 (to -8).

Hence, the value of y when x = 8 is -8

Answer:

30 years

Step-by-step explanation:

Given;

Average age of women = 27 years

Average age of men = 33 years

Number of women = 4

Number of men = 4

Total number of people in the office = 4+4 = 8

Sum of age of women = mean × number = 27 × 4 = 108 years

Sum of age of men = mean × number = 33 × 4 = 132 years

Total sum of age of people = 108 + 132 = 240 years

Mean age = total sum of age of people in the office/number of people in the office

Mean age of people = 240/8 = 30 years

Answer: Company B

Step-by-step explanation:

First we must calculate the area of the carpet. Variable A represents area.

[tex]14*12=A[/tex]

[tex]A=168[/tex]

So the area of the carpet is 168 square feet.

To find what company A will charge we will multiply the 168 by 2.75 they charge per square foot.

[tex]168*2.75= Company A\\[/tex]

Company A charges, $462, while Company B will charge $450 for the one room.

This means Company B has the better price.

Answer:

the two numbers are 3 and -4

Step-by-step explanation:

Product:  xy = -12, or x = -12/y

Sum:  x + y = -1, or -12/y + y = -1

Let's multiply all three terms by y to eliminate the fractional terms:

-12 + y^2 = -y, or

y^2 + y - 12 = 0

This factors into (y + 4)(y - 3) = 0, yielding y = -4 and y = 3.

Earlier we found that x = -12/y.  Here, if we choose y = -4, x = -12/(-4) = 3

and so the two numbers are 3 and -4.  Note that 3(-4) = -12, as required, and that 3 - 4 = -1, also as required.

Answer:

The top one, as x increases, y increases too.

Answer:

See below

Step-by-step explanation:

[tex] (x + 15)^2 - 10 = 0\\

(x + 15)^2 = 10 \\

(x + 15) = \pm\sqrt {10} \\

x + 15 = \pm 3.16227766\\

x + 15 = \pm 3.16\\

x = \pm 3.16 - 15\\

x = 3.16 - 15 \: or \: x = - 3.16 - 15\\

x = - 11.84\: or \: x = - 18.16\\
