Step-by-step explanation:
Since we are told that 10 is a zero,
(x−10) must be a factor:
F(x)=2x3−14x2−56x−40
F(x)=(x−10) (2x2+6x+4)
F(x)=2(x−10)(x2+3x+2)
F(x)=2(x−10)(x+2)(x+1)
So the other two zeros are
x = -2 and x= −1

If there are 125 boxes of prescription bottle labels at the beginning of inventory cycle, and 25 3/4 remain ,how many boxes of labels remain?
Answer:
Rounded to the nearest integer, 32 boxes of labels remain at the end of the inventory cycle.
Step-by-step explanation:
Given that there are 125 boxes of prescription bottle labels at the beginning of the inventory cycle, and 25 3/4 remain at the end of it, to determine how many boxes of labels remain the following calculation must be performed:
3/4 = 0.75 + 25 = 25.75
125 x 25.75 / 100 = X
3218.75 / 100 = X
32.1875 = X
Thus, rounded to the nearest integer, 32 boxes of labels remain at the end of the inventory cycle.

Answer:
m < -6 or m > 8
Step-by-step explanation:
m - 2 < -8
Add 2 to both sides of the inequality.
m < -8 + 2
m < -6
m/8 > 1
Multiply both sides of the equation by 8
m/8 ⋅ 8 > 1 ⋅ 8
Simplify.
m > 8

A spinner has three unusual sections: red, yellow, and blue.. The table shows the results of Nolan’s spins. Find the probability of landing on each color.
Answers:
Red = 1/3Yellow = 7/15Blue = 1/5====================================================
Explanation:
Add up all the frequencies in the table to see that there are 120+168+72 = 360 spins total.
Of those 360 spins, 120 of them land on red. The probability of landing on red is 120/360 = (120*1)/(120*3) = 1/3Since 168 land on yellow, this means the probability of landing on yellow is 168/360 = (24*7)/(24*15) = 7/15Lastly, we have 72 occurrences of blue out of 360 total spins. The probability of landing on blue is 72/360 = (72*1)/(72*5) = 1/5Find the area of the following figure:

The table shows a linear relationship between x and y. What is the rate of change of y with respect to x.
A. -9/2
B. 2/9
C. -2/9
D. 9/2
Answer:
A. -⁹/2
Step-by-step explanation:
Using any two pairs of values form the table, say (-12, 60) and (-6, 33),
Rate of change = ∆y/∆x
= (33 - 60) / (-6 -(-12))
= -27/6
= -9/2
Rate of change = -⁹/2
The rate of change of y with respect to x is -9/2
Option A is correct
For a linear relationship, the rate of change of y with respect to x is given by the formula:
[tex]\frac{\triangle y}{\triangle x} =\frac{y_2-y_1}{x_2-x_1} \\[/tex]
From the table:
[tex]x_1=-20, x_2=-12, y_1=96, y_2=60[/tex]
Substitute [tex]x_1=-20, x_2=-12, y_1=96, y_2=60[/tex] into the equation [tex]\frac{\triangle y}{\triangle x} =\frac{y_2-y_1}{x_2-x_1} \\[/tex]
[tex]\frac{\triangle y}{\triangle x} =\frac{60-96}{-12-(-20)} \\\\\frac{\triangle y}{\triangle x} =\frac{-36}{8}[/tex]
Reduce the expression to the lowest term by dividing the numerator and denominator by 4
[tex]\frac{\triangle y}{\triangle x} =\frac{-9}{2}[/tex]
The rate of change of y with respect to x is -9/2

the square root of the sum of twice a number and 3 is 6. find the number
Answer in fraction form = 33/2
Answer in decimal form = 16.5
===========================================================
Work Shown:
n = some number
2n = twice that number
2n+3 = "sum of twice a number and 3"
[tex]\sqrt{2n+3}[/tex] = square root of the previous expression
The equation we need to solve is [tex]\sqrt{2n+3} = 6[/tex]
We'll follow PEMDAS in reverse, undoing each operation, to isolate n
[tex]\sqrt{2n+3} = 6\\\\\left(\sqrt{2n+3}\right)^2 = 6^2 \ \ \text{ ... square both sides}\\\\2n+3 = 36\\\\2n+3-3 = 36-3 \ \ \text{ ... subtract 3 from both sides}\\\\2n = 33\\\\\frac{2n}{2}=\frac{33}{2} \ \ \text{ ... divide both sides by 2}\\\\n = \frac{33}{2}\\\\n = 16.5[/tex]
Answer:
[tex]\frac{33}{2}[/tex]
Step-by-step explanation:
In the problem, "The square root of the sum of twice a number and 3 is 6" can be converted to an equation that looks like this:
Let x be the number:
[tex]\sqrt{2x+3 = 6 }[/tex]
In order to solve the problem:
[tex]\sqrt{2x+3}^2=6^2[/tex]
By squaring both sides to remove the exponent:
[tex]{2x + 3 = 36}[/tex]
Simplify:
[tex]{2x+3-3=36-3}[/tex]
Subtract 3 from both sides:
[tex]{2x = 33 }[/tex]
Then Simplifying further:
[tex]\frac{2x}{2} = \frac{33}{2}[/tex]
Divide both sides by 2 to remove 2 from the x.
[tex]{x = \frac{33}{2} }[/tex]
Thus, meaning the answer is [tex]\frac{33}{2}[/tex]

If IM is reflected across the x-axis and then translated along the vector <4, 1>, in
which quadrant is the final image?
Answer:
Final image L"M" will lie in the fourth quadrant.
Step-by-step explanation:
Coordinates of the ends of segment LM,
L → (-3, 4)
M → (-3, 2)
Rule to reflect a point across x-axis is,
(x, y) → (x, -y)
By this rule, coordinates of the image point of L and M will be,
L(-3, 4) → L'(-3, -4)
M(-3, 2) → M'(-3, -2)
Further these image points are translated along the vector <4, 1>
Rule for this translation will be,
(x, y) → (x + 4, y + 1)
Now the image points of the points L' and M' will be,
L'(-3, -4) → L"(-3 + 4, -4 + 1)
→ L"(1, -3)
M'(-3, -2) → M"(-3 + 4, -2 + 1)
→ M"(1, -1)
Therefore, final image L"M" will lie in the fourth quadrant.

Determine whether Mean Value Theorem can be applied. If so, find all values x=c that satisfy the theorem, or explain why not.
Calculus AB AP
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Time taken = 2 hours 18 minutes
18 / 60 = 0.3 hours
Hence, time taken = 2.3 hours
Speed = distance / time
Speed = 26.2 / 11.3 = 11.39 mi/hr
Hence, according to the mean value theorem ;
The range of time taken is (0, 2.3) whereby a certain time, t exist when the runner attains a speed of 11.39
Since initial and final velocity is 0 ;
The runner attains a speed of 11 mi/hr between :
(0, 2.3) and (t, 2.3)
Mr. O. ran the Disney Marathon the AB AP is (0, 2.3) and (t, 2.3).
Given Data: Time taken = 2 hours 18 minutesTime taken =18 / 60
Time taken = 0.3 hours
Hence,
time taken = 2.3 hours
Speed = distance / timeSpeed = 26.2 / 11.3
Speed = 11.39 mi/hr
According to the mean value theorem ;
The range of time taken is (0, 2.3) whereby a certain time, t exist when the runner attains a speed of 11.39 Since initial and final velocity is 0 ;
The runner attains a speed of 11 mi/hr between : (0, 2.3) and (t, 2.3)
Thus, the AB and AP is (0, 2.3) and (t, 2.3)
