Answer: I think Rick is 16 and jeff is 6

The value of f(8) is -4.

Polynomials are sums of terms of the form k⋅xⁿ, where k is any number and n is a positive integer.

For example, 4x + 5x - 1 is a polynomial.

We can consider the polynomial to be:

f(x) = x - 12 so that when we divided by x - 8 we get a remainder of -4.

i.e

(x - 12) / (x-8)

x - 8 ) x - 12 ( 1

          x - 8          [ (x - 8) x 1 = x - 8 ]

              -4           [ we change the sign of the coefficient ]

                            [ x - 8 becomes (-x + 8) ]              

                            [ x gets canceled and -12 + 8 = -4 ]

We see that the quotient is 1 and the remainder is -4.

Now,

We can  use this polynomial f(x) = x - 12.

f(8) = 8 - 12 = -4

We can also directly say that the value of f(8) is -4 because the remainder is given as -4.

Thus,

The value of f(8) is -4.

Answer: ITS B

Step-by-step explanation:

Answer:

a)  y = -441.105 + 0.2232x

b)  2043

Step-by-step explanation:

Correlation measures how closely two variables are linked.

If two variables are correlated, you can draw a line of best fit on the scatter plot.

Plot the points from the table where:

(See attached graph).

We can see that the points lie close to a straight line. Therefore, a line of best fit with a positive slope can be drawn, since the two variables are positively correlated.

Linear regression is a method for finding the equation of a line of best fit on a scatter plot.

The regression line of y on x:

[tex]y = a + bx[/tex]

where a = y-intercept and b = slope

We cannot find the y-intercept from inspection of the scatter plot (attached) since we would need to extend the x-axis to thousands of years.

Therefore, to find the regression equation, use a graphing calculator:

[tex]y=-441.105+0.2232x[/tex]

To find the approximate year the movie ticket price will reach $15, substitute y = 15 into the equation and solve for x:

[tex]\implies -441.105+0.2232x=15[/tex]

[tex]\implies 0.2232x=456.105[/tex]

[tex]\implies x=2043.481...[/tex]

Therefore, the approximate year the movie ticket price will reach $15 is during 2043.

Note:

For this problem, we have used the line of best fit (regression line) to predict a value of that is outside the range of the original data. When using values outside the range to predict corresponding values, this is called extrapolation. These predictions can be unreliable because there is no evidence that the relationship described by the regression line is true for all values of x. Therefore, caution should be applied in these cases.

The radius of the circle whose circumference is 46mm comes out to be 7.32 mm

As we are been provided with that circumference of the circle is 46mm and we are told to find out the radius of the circle

The formula for circumference of circle = dπ where d is the diameter of the circle

Let us put the given values in the formula

           46 = d (3.14)

  46/3.14 = d

d= 14.64

The radius of the circle is half of the diameter of the circle which means r = d/2

The radius of the circle = 14.64/2 = 7.32mm

Hence, the radius of the circle whose circumference is 46mm comes out to be 7.32 mm

The approximate length is 0.62 years or 225 days.

A year is the time it takes for a planet, moon, or other celestial body to make one orbit around the Sun. ( when we take our solar system as an example). In the case of other exoplanets, the celestial bodies, moon, and other planets orbit around the main star. The period of the moon's orbit around the earth is related to the moon.

The reference point is very important in determining the exact length of a year. The length is dependent upon the reference point used for the orbital movement.

Jupiter completes a Single orbit once every 4333 days, due to which one Jupiter year is equivalent to 11.86 earth years.

Function :

trigonometric function, in mathematics, one of six functions (sine [sin], cosine [cos], tangent [tan], cotangent [cot], secant [sec], and cosecant [csc]) that represent ratios of sides of right triangles. These six trigonometric functions in relation to a right triangle are displayed in the figure.

They are also known as circular functions since their values can be defined as ratios of the x and y coordinates (see coordinate system) of points on a circle of radius 1 that correspond to angles in standard positions. Trigonometry can be easily applied to surveying, engineering, and navigation problems in which one of a right triangle’s acute angles and the length of a side are known and the lengths of the other sides are to be found.

The fundamental trigonometric identity is sin2θ + cos2θ = 1, in which θ is an angle.

f (x) = x*3/2

f(8) = 8*3/2 = 12

The minimum of the objective function, f, subject to the constraints is (10.3, 8.3)

Plugging in 5 points, the intersections of the bounds of the 5 constraints, yields the least solution, f = 7x + 4y.

(0,60) provides 240

(6,30) f= 42+120 = 162

(10.3,8.3) = 72.1+ 33.2 = 105.3

(48,2) = 336+ 8 = 344

(60,0) = 420

At the moment when the minimum f is approximately (10.3,8,3)

5x+y = 60 and x+6y = 60 intersect at that point. Multiply the first equation by 6 and take the second equation out to get 30x + 6y = 360.

x + 6y = 60

29x = 300

Rounding to 10.3, x = 300/29 = about 10.345
