The value of ∫[6, -10]g(x)dx is 2.
How to solveWe are given two integrals: ∫[-104, -10]g(x)dx = -3 and ∫[6, 4]g(x)dx = 5.
We need to find the value of ∫[6, -10]g(x)dx.
Notice that the desired integral's interval is just the union of the given intervals.
Therefore, we can obtain the value of the desired integral by summing the values of the two given integrals: ∫[6, -10]g(x)dx = ∫[-104, -10]g(x)dx + ∫[6, 4]g(x)dx = -3 + 5 = 2.
Thus, the value of ∫[6, -10]g(x)dx is 2.

What is the difference quotient for the function f (x) = negative startfraction 1 over 5 x minus 12 endfraction?
The difference quotient of f(x) is \(\frac{-\frac{1}{h}+ 5}{5x+ h -12}\) .
According to the given question.
We have a function
f(x) = -1/(5x -12)
As we know that, the difference quotient is a measure of the average rate of change of the function over and interval.
The difference quotient formula of the function y = f(x) is
[f(x + h) - f(x)]/h
Where,
f(x + h) is obtained by replacing x by x + h in f(x)
f(x) is a actual function.
Therefore, the difference quotient formual for the given function f(x)
= [f(x + h) - f(x)]/h
= \(\frac{\frac{-1}{5(x+h)-12} -\frac{-1}{5x-12} }{h}\)
= \(\frac{\frac{-1}{5x + 5h -12}+\frac{1}{5x-12} }{h}\)
= \(\frac{\frac{-1+5h}{5x + 5h-12} }{h}\)
= \(\frac{-1+5h}{(5x +h-12)(h)}\)
= \(\frac{-1+5h}{5xh + h^{2} -12h}\)
= \(\frac{h(-\frac{1}{h}+5) }{h(5x+h-12)}\)
= \(\frac{-\frac{1}{h}+ 5}{5x+ h -12}\)
Hence, the difference quotient of f(x) is \(\frac{-\frac{1}{h}+ 5}{5x+ h -12}\) .

Choose an expression that is equivalent to negative four raised to the fourth power divided by negative four raised to the second power.
negative four raised to the second power divided by negative four raised to the fourth power
negative four raised to the fifth power divided by negative four
negative four raised to the sixth power divided by negative four raised to the fourth power
negative four divided by negative four raised to the fifth power
Answer:
C
Step-by-step explanation:
negative four raised to the sixth power divided by negative four raised to the fourth power
because negative four raised to the fourth power divided by negative four raised to the second power = negative four raised to the second power
negative four raised to the sixth power divided by negative four raised to the fourth power also = negative four raised to the second power
The answer is A: negative four raised to the second power divided by negative four raised to the fourth power. This is obtained by applying the rules of exponents, specifically, when dividing with the same base, subtract the exponents.
Explanation:This question pertains to exponents division rules. According to the rule of Power of a Power in exponents, when you divide expressions with the same base, you subtract the exponents. So if you have negative four raised to the fourth power (-4⁴) and you want to divide it by negative four raised to the second power (-4²), you subtract 2 from 4 to get an exponent of 2. This results in a negative four raised to the second power (-4²). So, the correct option from the given choices in your question is A: negative four raised to the second power divided by negative four raised to the fourth power.

Suppose a central angle is inscribed inside of a circle. The angle measures 36 degrees and the minor arc is 15 cm. Calculate the area of the circle and round your answer to two decimal places.
The area of the circle is 1790.49 centimeters square
To calculate the area of the circle, we shall need the radius of the circle
We can get the radius from the arc length
Mathematically, the length of an arc is;
\(\frac{\theta}{360\text{ }}\text{ }\times\text{ 2}\pi r\)From the question, the length is 15 cm while the central angle is 36
Thus we have;
\(\begin{gathered} 15\text{ = }\frac{36}{360}\text{ }\times\text{ 2}\pi r \\ \\ 150\text{ = 2}\pi r \\ \\ \pi r\text{ = 75} \\ \\ r\text{ = }\frac{75}{\pi} \end{gathered}\)Mathematically, the area of the circle will be;
\(\begin{gathered} A\text{ =}\pi\text{ }\times r^{2^{}} \\ \\ A\text{ = }\pi\text{ }\times\text{ }\frac{75}{\pi}\text{ }\times\text{ }\frac{75}{\pi} \\ \\ A\text{ = }\frac{75^2}{\pi}\text{ = 1,790.49 cm} \end{gathered}\)explain what each term in this model means and why it has the algebraic form (for example, sp2) that it does.
The s-orbital is spherical in shape, while the p-orbitals are composed of two lobes that are directed at an angle of 120 degrees apart.
It is composed of three atomic orbitals: one s-orbital and two p-orbitals. The s-orbital is spherical in shape, while the p-orbitals are composed of two lobes that are directed at an angle of 120 degrees apart. The combination of these three orbitals forms a hybrid orbital that is shaped like a flat trigonal planar, with a bond angle of 120 degrees. This hybrid orbital is known as the sp2 hybrid orbital.
The "s" in sp2 stands for the s-orbital, which is a single, spherical orbital. The "p" represents the two p-orbitals, which have two lobes and form an angle of 120 degrees with each other. The "2" in sp2 indicates that two p-orbitals are involved in the hybridization process. The hybridization of the s and two p-orbitals creates the sp2 hybrid orbital, which is trigonal planar in shape.

Tekan-Tekan Sdn. Bhd. has order for 200 Model AS-120 calculator for delivery on day 200. The calculator consists of three parts. Components 2 and 3 form subassembly 1 . Sub-assembly 1 and component 4 form the final assembly. Following are the work centers and times of each operation. Table Q3(a) shows routine file of the operation. Assuming: - Only one machine is assigned to each operation - The factory works on 8-hour shift, 5 days a week - All parts move in one lot of 200. (a) Illustrate the backward schedule based on the information given above. (12 marks) (b) Identify when component 3 must be started to meet the delivery date. (2 marks)
Component 3 must be started on day 197 to meet the delivery date of day 200.
To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.
(a) Backward schedule:
Operation | Work Center | Time (hours) | Start Day
--------------------------------------------------------
Final Assembly | Work Center 1 | 1 | 200
Sub-assembly 1 | Work Center 2 | 2 | 199
Component 4 | Work Center 3 | 3 | 197
Component 2 | Work Center 4 | 4 | 196
Component 3 | Work Center 5 | 3 | ????
(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.
From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.
Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.
Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

Answer:
Step-by-step explanation:

The inequality that could be used to find the number of seconds will be 15.4 - 0.5t < 5.4 + 0.75t.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that,
Xander's water bottle has 15.4 oz of water in it and Xander is drinking 0.5 oz of water each second as a result the obtained equation is,
15.4 - 0.5t
On the other hand, Leon's water bottle has 5.4 oz of water in it and Leon is adding 0.75 oz of water each second as a result the obtained equation is,
5.4 + 0.75t
Xander < Leon,
15.4 - 0.5t < 5.4 + 0.75t
On simplifying we get
t > 8
Thus, the inequality that could be used to find the number of seconds will be 15.4 - 0.5t < 5.4 + 0.75t.

To determine the number of gallons of paint needed to cover office 143, we need to know the square footage of the office.
Once we have that information, we can divide the square footage by the coverage rate per gallon to calculate the required amount of paint.
Let's assume the square footage of office 143 is 800 square feet.
Number of gallons needed = Square footage / Coverage rate per gallon
Number of gallons needed = 800 square feet / 50 square feet per gallon
Number of gallons needed = 16 gallons
Therefore, you would need approximately 16 gallons of paint to cover office 143, assuming each gallon covers 50 square feet.
