the answer is negative 168

Answer:

Step-by-step explanation:

Circumference is found by multiplying the diameter by PI,

so a circumference of 6PI means the diameter is 6 inches.

Area is found using the formula PI x r^2

r = 1/2 the diameter

r = 6/2 = 3

The area becomes 3^2 x PI = 9PI inches.

Answer:

0 has multiplicity 1

-2 has multiplicity 3

-4 has multiplicity 2

5 has multiplicity 4

Step-by-step explanation:

The multiplicity of the root of a polynomial function, refers to the number of time the root repeats itself.

The given function is

[tex]k(x)=x(x+2)^3(x+4)^2(x-5)^4[/tex]

To find the roots of this function, we equate the function to zero.

[tex]x(x+2)^3(x+4)^2(x-5)^4=0[/tex]

We now use the zero product principle, to obtain;

[tex]x=0[/tex], with multiplicity 1

[tex](x+2)^3=0[/tex]

[tex]\Rightarrow x=-2[/tex], with multiplicity 3

[tex](x+4)^2=0[/tex]

[tex]\Rightarrow x=-4[/tex], with multiplicity 2

[tex](x-5)^4=0[/tex]

[tex]\Rightarrow x=5[/tex], with multiplicity 5.

Answer:

The roots of the function;

[tex]k(x)=x(x+2)^3(x+4)^2(x-5)^4[/tex]

Step-by-step explanation:

Given information:

The function;

[tex]k(x)=x(x+2)^3(x+4)^2(x-5)^4[/tex]

As, we know that multiplicity of any function is defined as the number of times the roots repeats in the solution.

Hence, we need to find the roots of the function

So, equating the function to [tex]0[/tex]

[tex]x(x+2)^3(x+4)^2(x-5)^4=0[/tex]

As, [tex]x=0[/tex] , is having multiplicity [tex]1[/tex].

[tex](x+2)^3=0\\x=-2[/tex]

Having a multiplicity  3.

Now,

[tex](x+4)^2=0\\x=-4[/tex]

Having a multiplicity  2.

And,

[tex](x-5)^4=0\\x=5[/tex]

Having multiplicity  4.

According to Casio Calculations the Answer is C.

Answer:

3/8 or 37.5%

Step-by-step explanation:

There are a total of 8 possible outcomes. B appears only 3 times in those 8 outcomes. Therefore, the chances of landing on B is 3 out of 8 or 3/8.

The probability of B in percent is 37.5 %.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Here, Total outcomes = {A, A, B, B, B, C, C, C}

                 n(S) = 8

Now, possibility of B = {B, B, B}

                n(B) = 3

Probability of B = Favorable outcomes/ total outcomes

                           = n(B)  / n(S)

                           = 3/8

                           = 0.375

                           = 37.5 %

Thus, the probability of B in percent is 37.5 %.

Answer: 1 3/4 gallons

Step-by-step explanation: In order to determine the total number of gallons in the recipe you need to convert 8 cups to gallons. There are 16 cups in 1 gallon. In order to determine how many gallons 8 cups is you need to divide 8/16 = 1/2 gallon.

The total number of gallons is 1 1/4 + 1/2.

1 1/4 + 1/2 = 1 3/4 gallons.

Part A: You can add the time in hours to find the total. 1/3 + 3/4 + 4/6 + 1/2 = 2 1/4 hours which can also be expressed as 2 hours and 15 minutes (1/4 of an hour is 15 minutes.)

Part B: It takes him 3/4 hr to do homework, 4/6 hr to play soccer, and 1/2 hr to play piano. 3/4 + 4/6 + 1/2 = 1 11/12 hrs or 1 hour and 55 minutes (11/12 of an hour is 55 minutes.) Therefore Kevin is wrong.

Answer:

19.32

Step-by-step explanation:

To find the missing number, we need to solve for the total of the left side of the equation.

Total = 8.4(1.5 + 2.3)

Total = 8.4(3.8)

Total = 31.92

Now we subtract the total to the only value on the right side.

Missing number = 31.9-12.6

Missing number = 19.32

8.4(1.5+2.3) = 12.6 + 19.32

ANSWER

A. 27.5

EXPLANATION

The average rate of change of the given quadratic function on the interval;

x=2 to x=4 is the slope of the secant line connecting the points (2,f(2)) and (4,f(4)).

This implies that the average rate of change is

[tex] = \frac{f(4) - f(2)}{4 - 2} [/tex]

From the table,

[tex]f(4) = 64[/tex]

and

f(2)=9.

The average rate of change becomes

[tex] = \frac{64 - 9} {4 - 2} [/tex]

Answer:

D.) 2.5 miles

Step-by-step explanation:

The first step required for solving this problem is to calculate the midpoint between the theater and the mall (2, 1.5). Then use the distance formula to calculate the distance from the bowling alley to the mall.

The distance from the bowling alley to the mall is 2.5 miles. The coordinates of the midpoint, which is the location of the bowling alley, are calculated first. Then, using the Pythagorean theorem, the distance to the mall is found by calculating the square root of the sum of the squares of the horizontal and vertical distances.

The task is to calculate the distance from the bowling alley to the mall if the bowling alley is at the midpoint between the movie theater at (0,0) and the mall at (4,3). First, we find the coordinates of the midpoint, which is the average of the x-coordinates and the y-coordinates of the two points respectively. Thus, the midpoint is located at:

So, the bowling alley is at point (2, 1.5). Secondly, we use the Pythagorean theorem to find the distance from the bowling alley to the mall:

Applying the distance formula (or Pythagorean theorem):

Distance = √( Δx² + Δy² ) = √( 2² + 1.5² ) = √( 4 + 2.25 ) = √6.25 = 2.5 miles

Therefore, the approximate distance from the bowling alley to the mall is 2.5 miles, which corresponds to answer (D).

Answer:

1 line of symmetry through the middle making 2 v s

Step-by-step explanation:

Answer: The figure has 1 line of symmetry.

Step-by-step explanation:

A figure is said to has a line of symmetry if we can draw a line that divides the entire figure into two equal halves, so that each half appears as a reflection image or the mirror of the other.

In the given picture , if given a figure of alphabet W.

It has only a vertical symmetry ( see below the line of symmetry divides W into two Vs) but no horizontal symmetry and any other symmetry.

Therefore , it has only one line of symmetry.

Hence, the figure has 1 line of symmetry.

Original measurements:

L = 4; W = 6; H = 7

surface area = 2(LW + LH + HW)

surface area = 2(4 * 6 + 4 * 7 + 6 * 7)

surface area = 2(24 + 28 + 42)

surface area = 2(94)

surface area = 188

Doubled measurements:

L = 8; W = 12; H = 14

surface area = 2(LW + LH + HW)

surface area = 2(8 * 12 + 8 * 14 + 12 * 14)

surface area = 2(96 + 112 + 168)

surface area = 2(376)

surface area = 752

The surface area was 188 square inches and it became 752 square inches.

752/188 = 4

As the side lengths increased by a factor of 2, the surface area increased by a factor of 4.

Step-by-step explanation:

dh/dt=-32t+32

When velocity, dh/dt, is equal to zero, the object is at its maximum height.

dh/dt=0 only when 32t=32, t=1 second, so the maximum height is h(1)

h(1)=-16+32=16ft

Using algebra

The maximum height will occur at the midpoint between the two zeros of the height function because of a quadratics symmetry...

h(t)=0 when

-16t^2+32t=0

-16t(t-2)=0

so t=0 and 2

The midpoint is t=1

And of course this will give you the same as we found earlier.  The maximum height is h(1) ft

Answer:

dh/dt=-32t+32When velocity, dh/dt, is equal to zero, the object is at its maximum height.dh/dt=0 only when 32t=32, t=1 second, so the maximum height is h(1)h(1)=-16+32=16ftUsing algebraThe maximum height will occur at the midpoint between the two zeros of the height function because of a quadratics symmetry...h(t)=0 when-16t^2+32t=0-16t(t-2)=0so t=0 and 2The midpoint is t=1

Answer:

24 inches

Step-by-step explanation:

1/2 of 4 feet is 2 feet

you know that 1 feet = 12 inches

So 2 feet = 24 inches

The "-4" tacked onto the 2x^2 term will move the entire parabola down 4 units. This is because y = 2x^2 becomes y-4 = 2x^2-4

The y-4 means we move every y coordinate down 4 spots. The x coordinate stays the same.

first off, let's solve the "given" line for "y", that way we can put it in slope-intercept form to see what its slope might be.

[tex]\bf 10x+2y=-2\implies 2y=-10x-2\implies y=\cfrac{-10x-2}{2} \\\\\\ y=\cfrac{-10x}{2}-\cfrac{2}{2}\implies y=\stackrel{\stackrel{m}{\downarrow }}{-5}x-1\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

well, a parallel line to that one, will have the same exact slope, so then, we're really looking for the equation of a line whose slope is -5 and runs through (0 , 12)

[tex]\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{12})~\hspace{10em} slope = m\implies -5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-12=-5(x-0) \\\\\\ y-12=-5x\implies y=-5x+12[/tex]

To find intervals of increase or decrease, analyze the function's derivative or slope. Linear regression uses a straight line equation to estimate these trends graphically. Graphs are helpful for visually representing increase or decrease rates and other numerical relationships.

To find intervals of increase or decrease in a function, you need to analyze the function's derivative. If the derivative is positive over an interval, the function is increasing; if the derivative is negative, the function is decreasing. An example of observing such behavior is through graphical analysis, where you look for portions of the graph that have an upward or downward slope, respectively.

Linear regression is a tool used to determine the rate of increase or decrease over a set of data points. By fitting a line X = S\u00d7t + I, where S is the slope and I the intercept with the vertical axis, one can estimate the trend or rate of change, assuming a linear relationship.

To describe the rate of growth in various contexts, such as population growth or economic data, graphs can display these trends visually. For different applications, such as contour mapping in geography, the interval of change might be adjusted to represent details accurately. A constant rate of growth assumption, however, isn't always correct and must be adjusted depending on the circumstances.

Answer:

This is because this equation equals 0 when x = -5

Step-by-step explanation:

To find this, plug the value in for x.

-1.3x - 6.5

-1.3(-5) - 6.5

6.5 - 6.5

0

The expression -1.3x - 6.5 evaluated at x=-5 equals zero, which is why it is neither positive nor negative.

To verify this let's evaluate it step by step.

Substitute x = -5 into the expression:

-1.3(-5) - 6.5

Then, multiply -1.3 by -5:

-1.3 * (-5) = 6.5

Then, subtract 6.5:

6.5 - 6.5 = 0

The expression -1.3x - 6.5 evaluated at x=-5 equals zero, which is why it is neither positive nor negative.
