x³ + 8
8 is the cube of 2, so we can write the above expression as sum of two cubes as:
x³ + 2³
Using the formula of sum of cubes, we can write:
x³ + 2³ = (x + 2)(x² - 2x + 4)
Thus, option B gives the correct answer

Which summation formula represents the series below?
13 + 9 + 5 + 1
Answers
The sum of the series is 28.
The series 13 + 9 + 5 + 1 is an arithmetic series with a common difference of -4. To express this in summation (sigma) notation and find its sum, we first identify the first term (a1) as 13 and the common difference (d) as -4.
Next, we determine the number of terms (n). The series decreases by 4 each time, so we find the number of steps it takes to go from 13 to 1, which are 4 terms in total (13, 9, 5, 1).
We can write the summation formula for an arithmetic series as Sn = n/2 * (2a1 + (n-1)d), where Sn is the sum of the first n terms. With n = 4, a1 = 13, and d = -4, we plug these into the formula:
S4 = 4/2 * (2(13) + (4-1)(-4))
S4 = 2 * (26 - 12)
S4 = 2 * 14
S4 = 28
The sum of the series is 28.

12+5v=2v-9 please show step by step!
Answers
Subtract 12 from both sides.
5v = 2v - 21
Subtract 2v from both sides.
3v = -21
Divide both sides by 3.
v = -7
To get it, combine like terms and restrain the variable. Segregating both sides by 3 gives the solution to the equation as v = -7.
How to solve the expressionTo solve the condition 12 + 5v = 2v - 9, take after these steps:
Step 1: Segregate the variable terms on one side of the condition and the steady terms on the other side.
Subtract 2v from both sides to move the variable term to the cleared outside:
12 + 5v - 2v = 2v - 9 - 2v
Alter both sides of the condition:
12 + 3v = -9
Step 2: Separate the variable term by moving the reliable term to the other side.
Subtract 12 from both sides to move the dependable term to the proper side:
12 + 3v - 12 = -9 - 12
Unwind both sides of the condition:
3v = -21
Step 3: Light up for v by confining both sides of the condition by the coefficient of v, which is 3.
Portion by 3 to clarify for v:
v = -21 / 3
Streamline the division:
v = -7
The solution to the equation is v = -7.

Answers
Answer: The probability of hitting an odd number three times is [tex]3\dfrac{3}{8}[/tex] times more than the probability of hitting an even number 3 times.
Step-by-step explanation:
From the given picture , the total total number of sections in the spinner = 5
Sections having Odd numbers = 3
Sections having Even numbers =2
We know that , [tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
So , probability of hitting an odd number = [tex]\dfrac{3}{5}[/tex]
Probability of hitting an even number = [tex]\dfrac{2}{5}[/tex]
Since all events are independent of each other ,
So , probability of hitting an odd number three times = [tex](\dfrac{3}{5})^3=\dfrac{27}{125}[/tex]
Probability of hitting an even number three times = [tex](\dfrac{2}{5})^3=\dfrac{8}{125}[/tex]
Divide [tex]\dfrac{27}{125}[/tex] by [tex]\dfrac{8}{125}[/tex] , we get
[tex]\dfrac{27}{125}\div\dfrac{8}{125}\\\\=\dfrac{27}{125}\times\dfrac{125}{8}=\dfrac{27}{8}=3\dfrac{3}{8}[/tex]
Hence, the probability of hitting an odd number three times is [tex]3\dfrac{3}{8}[/tex] times more than the probability of hitting an even number 3 times.

You are traveling to Chicago for a job interview. You leave Toledo, Ohio, at 5:45 A.M. and arrive in Elkhart, Indiana, at 8:15 A.M.. The distance from Toledo to Elkhart is 136 miles; the distance from Toledo to Chicago is 244 miles. The speed limit is 65 mph. What is the minimum speed you must maintain in order to arrive in Chicago before 10:30 A.M.
Answers
To get from Elkhart to Toledo is 108 miles. (244-136)
It will take 2.25 hours to get there. From 8:15 am to 10:30 am is 2 1/4 hours.
108 miles/2.25 hours = 48 miles per hour. You must travel at an average speed of 48 miles per hour.

When designing a building, you must be sure that the building can withstand hurricane-force winds, which have a velocity of 73 mi/h or more. The formula f=0.004av^2 gives the force F in pounds exerted by a wind blowing against a flat surface. A is the area of the surface in square feet, and v is the wind velocity in miles per hour. How much force is exerted by a wind blowing at 81 mi/h against the side of the building shown?
Answers
10825.65 pounds
The first step is calculate the surface area of the flat surface shown
Surface area of the rectangle = length * width = 25*12.9 = 322.5 square feet
Surface area of the triangle = 1/2 *base*height = 1/2*25*7.2 = 90 square feet
Total surface area = 322.5 +90 = 412.5 square feet
Total force = 0.004*a*v^2 = 0.004*412.5*81^2 = 10,825.65 pounds
