what is the missing number in the synthetic division problem below?
(everything in picture)
Answers
When performing synthetic division, we bring down the first number in the box. We then multiply this number by the number outside the box, and place that result under the second number in the box. We add these two numbers and bring that sum down.
We then continue this process by multiplying this second number by the number outside the box, and place the result under the third number in the box. We then add the two numbers in the third column and bring the sum down. The missing number is under this column; that means it is found by adding 2+8, so it is 10.
In the given problem , missing number in the synthetic division is equal to [tex]10[/tex].

What is the equation of the midline for the function y = 2sin(x - π) + 3
Answers
The equation of the midline for the function 2sin (x - π) + 3 is y = 3.
What is the Midline of a Function?The midline of a function is the line horizontal to the minimum value and maximum value of the function.
Given function is 2sin (x - π) + 3.
We know the trigonometric formula,
sin (A - B) = sin A cos B - cos A sin B
sin (x - π) = sin x cos π - cos x sin π
= (sin x × -1) - (cos x × 0) [Since cos π = -1 and sin π = 0]
= -sin x
So, 2sin (x - π) + 3 = -2sinx + 3
Now, we know that,
-1 ≤ sin x ≤ 1
Multiplying whole sides by -2,
2 ≥ -2sin x ≥ -2
[since the inequality sign changes when negative is multiplied or divided]
Adding 3 throughout,
5 ≥ -2sin x + 3 ≥ 1
Maximum value is 5 and minimum value is 1.
Midline value = (5 + 1) / 2 = 3
So the equation of the midline is y = 3.
Hence the equation of midline is y = 3.

If the height of Mount Everest is about 8.8×103 meters, and the height of the Empire State Building is about 3.8×102 meters, which of these statements is true?
Answers
Answer:
option C is correct, i.e. Mount Everest is about 23 times as tall as the Empire State Building .
Step-by-step explanation:
Given options are:-
A. There is no way to compare these heights .
B. Mount Everest is about 40 times as tall as the Empire State Building .
C. Mount Everest is about 23 times as tall as the Empire State Building .
D. The Empire State Building is about 23 times as tall as Mount Everest.
Given the height of Mount Everest is about 8.8×10^3 meters, and the height of the Empire State Building is about 3.8×10^2 meters.
Finding ratios of given heights:-
[tex]\frac{Mount\;\;Everest}{Empire\;\;State\;\;Building} =\frac{8.8*10^3m}{3.8*10^2m} \\\\\frac{Mount\;\;Everest}{Empire\;\;State\;\;Building} =23.15789474 \approx 23 \\\\Mount\;\;Everest=23*(Empire\;\;State\;\;Building)[/tex]

4.Krissa drew a circle with a radius of 4 inches.
Fill in the blanks.
The area of the circle is _______ square inches and the circumference is _______ inches.
64π, 16π
16π, 8π
16π, 64π
8π, 16π
Answers
Explanation:
1) To calculate the area use the formula:
Area = π (radius)^2
radius = 4 in => area = π (4 in)^2 = 16π in^2
2) To compute the circumference use the formula:
Circumference = 2π(radius)
=> Circumference = 2π (4 in) = 8π in.
To calculate the area of a circle, use the formula A = πr², where r is the radius. For this specific circle with a radius of 4 inches, the area is 16π square inches, and the circumference formula is C = 2πr, resulting in a circumference of 8π inches.
To find the area of a circle: A = πr². Substituting the given radius of 4 inches, we get Area = π(4)² = 16π square inches. The circumference of a circle is C = 2πr. Substituting the radius, we get C = 2π(4) = 8π inches.
Question 4 find the indicated probability or percentage for the normally distributed variable. the volumes of soda in quart soda bottles are normally distributed with a mean of 32.3 oz and a standard deviation of 1.2 oz. what is the probability that the volume of soda in a randomly selected bottle will be less than 32 oz?
Answers
First, we need to find the z-score. That is the number of standard deviations below the mean.
(32 - 32.3) / 1.2 = -0.25
A bottle of 32 oz is -0.25 standard deviations below the mean. Use a standard normal distribution probability table and you will find the 40.13% of the scores are below a z-score of -0.25.

So 't' is the independent variable, and 'f(t)' is the dependent variable.
The wording of the second option, the second to last, and the last is all correct. The questions says "let 't' be the time in years after 2000", so if 't' were say 5, this would mean 5 years after 2000 or 2005. The question also states "let f(t) be the amount of garbage", so the result must be the amount of garbage.
So now we just need to confirm if the calculations were done correctly.
Option 2:
[tex]\sf f(2)=1233[/tex]
This is the same thing as saying if you plug in 2 for 't', you will get 1233, let's try it:
[tex]\sf f(t)=1200\cdot (1.05)^t[/tex]
Plug in 2 for 't':
[tex]\sf f(2)=1200\cdot (1.05)^2[/tex]
Simplify the exponent:
[tex]\sf f(2)=1200\cdot (1.1025)[/tex]
Multiply:
[tex]\sf f(2)=1323[/tex]
So option 2 is incorrect, and we see also that option 6 is correct. Now for the last one:
Option 7:
[tex]\sf f(4)=1458.6[/tex]
This is the same thing as saying if you plug in 4 for 't', you will get 1458.6, let's try it:
[tex]\sf f(t)=1200\cdot (1.05)^t[/tex]
Plug in 4 for 't':
[tex]\sf f(4)=1200\cdot (1.05)^4[/tex]
Simplify the exponent:
[tex]\sf f(4)=1200\cdot (1.21550625)[/tex]
Multiply:
[tex]\sf f(4)\approx 1458.6[/tex]
So the last option is also correct.
So your answers are options 3, 4, 6 and 7.

The opening of the tunnel can be modeled by the graph of the equation y=-0.18x^2+4.4x-12 where x and y are measured in feet. Find the maximum height of the tunnel.
Answers
2. You have:
y=-0.18x²+4.4x-12
a=-0.18
b=4.4
3. You must apply the following formula:
x=-b/2a
x=-4.4/2(-0.18)
x=-4.4/-0.36
x=12.22
4. When you susbtitute x=12.22 into the equation y=-0.18x²+4.4x-12, you obtain:
y=-0.18x²+4.4x-12
y=-0.18(12.22)²+4.4(12.22)-12
y=14.88 feet
5. The answer is: The maximum height of the tunnel is 14.88 feet
Consider the following pair of equations:
y = x + 4
y = −2x − 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answers
y = x + 4
y = -2x - 2
To solve the system of equation by substitution, you would substitute one variable for it's equivalent expression. Combining the pair of equations into one equation in only one variable. The easiest way to do this is by substituting out the variable y because it is already alone on one side of the equal sign. Substitute the y in the second equation for: x+4
x+4 = -2x - 2
solve for x
x + 2x = -2 -4
3x = -6
x = -2
now use the value for x to find y by putting into either equation.
y = x + 4
y = (-2) + 4
y = 2
solution is: (-2, 2)

BUT it only gives you details on the perimeter of the fence. One of the sides of the area enclosure will be used from his fence and he has a maximum of 1,000 meters available for a perimeter... So the first step is to set up a perimeter equation and solve for the dimensions, before solving the max area problem
The equation for the perimeter will be:
2 (Width) + 1 (Length) = 1,000 m
Theres only 1 length being included in the equation because the fence the farmer has will be used instead of the building materials.
Solving for Length =
L = 1,000 m - 2 Width
Now using this equation (and replacing the L) into Area of a rectangle:
Length * Width = (1,000 m - 2 W) * W =
Area = - 2(W^2) + 1,000 W
Now that we have the area, there are a few methods to find the maximum amount. Using calculus we can find the derivative of the function and solve for critical points to find extrema points and find the absolute maximum area.
You can also solve this using algebra by factoring this function because its a quadratic and then you can solve for the highest values. y = -2x^2 +1000x
= -2x(x + 500) where x = 0 and -500
Checking at x = -1, y(-1) = 998
***** EDIT *****
Sorry, the question is only asking for the dimensions of the fence. Its not asking for you to solve the actual maximum size.
The dimensions would be 2 Width x Length

8π/9 is coterminal with 62π/9 and lies between 0 and 2π.
Given that, the angle between 0 and 2 π in radians that is coterminal with the angle 62π/9 in radians.
What is the coterminal with the angle?The coterminal angles are the angles that have the same initial side and the same terminal sides. We determine the coterminal angle of a given angle by adding or subtracting 360° or 2π to it.
To find a coterminal angle, add or subtract any multiple of 2π, that is
62π/9 - 2π = (62π-18π)/9
44π/9 - 2π = 26π/9
26π/9 - 2π = 8π/9
Therefore, 8π/9 is coterminal with 62π/9 and lies between 0 and 2π.
