Answer:
C) \(g(x)=\sqrt[3]{\frac{x+2}{4}}\)
Step-by-step explanation:
\(f(x)=4x^3-2\)
\(y=4x^3-2\)
\(x=4y^3-2\)
\(x+2=4y^3\)
\(\frac{x+2}{4}=y^3 \)
\(\sqrt[3]{\frac{x+2}{4}}=y \)
\(f^{-1}(x)=\sqrt[3]{\frac{x+2}{4}}\)
\(g(x)=\sqrt[3]{\frac{x+2}{4}}\)
A kids pool had a small opening through which water sometimes leaked out. Water was poured into the pool from time to time. The graph shows the amount of water in the pool (y), in gallons, at certain times (x), in hours.
Which of the following statements best describes the amount of water in the pool ?
1) it is increasing during the time interval 4
2) it is increasing during the time interval 10
3) it is decreasing during the time interval 4
4) it is decreasing during the time interval 10
The best statement that describes the amount of water in the pool is that it is decreasing during the time interval 4. That is option 3.
How to determine the the interval of the water in the pool?To determine the time interval of the water in the pool the following is carried out.
At 0 hour, the water is at the level of = 40 gallons
At 1 hour, the water decreased to = 25 gallons.
At 2 hours, the water decreased to = 10 gallons.
The water remained at a constant level till 4 hours.
Therefore, the amount of water in the pool is that it is decreasing during the time interval 4.

In computer architecture, registers are special storage locations within the CPU that hold data temporarily. These registers can hold values in binary, decimal, or hexadecimal formats. In this scenario, we have two registers x5 and x6, holding hexadecimal values. We will use these values to answer the given questions about register manipulation.
a) To determine the contents of register x31 after the instruction "addi x31, x5, 32", we need to add 32 to the value in x5 and store the result in x31. The value in x5 is 01a74cd0hex, which is equivalent to 277968848 in decimal. Adding 32 to this value, we get 277968880 decimal. Therefore, the contents of register x31 after the instruction is executed would be 277968880 decimal.
b) To determine the contents of register x28 after the instruction "add x28, x5, x6", we need to add the values in x5 and x6 and store the result in x28. The value in x5 is 01a74cd0hex, which is equivalent to 277968848 decimal. The value in x6 is 00467b44hex, which is equivalent to 458804 decimal. Adding these two values, we get 278427652 decimal. Therefore, the contents of register x28 after the instruction is executed would be 278427652 decimal.
c) To determine the contents of register x29 after the instruction "ld x29, 1056decimal (x30)", we need to load the value at memory location 1056decimal + the value in register x30 into register x29. The value in register x30 is not given in this scenario, so we cannot determine the contents of register x29.
d) To determine the contents of register x29 after the instruction "sd x28, 16 decimal (x29)", we need to store the value in register x28 at memory location 16 decimal + the value in register x29. The contents of register x28 is 278427652 decimal

Question A class of 25 students took a spelling test. Two students scored 100 on each test, nine students scored 95 on each test, ten students scored 90 on each test, three students scored 80 on each test and one student scored 70. What is the average score of the spelling test rounded to one decimal place? Enter your answer in the box.
The average score of the spelling test is 90.6%
To find the average score of the test, we need to add up all the scores and divide by the total number of students. We can think of the average score as the "typical" or "representative" score of the entire class.
First, let's add up all the scores:
2(100) + 9(95) + 10(90) + 3(80) + 1(70) = 200 + 855 + 900 + 240 + 70 = 2265
Next, we divide by the total number of students:
Average score = (2 + 9 + 10 + 3 + 1) / 25 * 100% = 25 / 25 * 100% = 90.6%
Therefore, the average score of the spelling test is 90.6% when rounded to one decimal place.

A mountainer climbed 1000' at a rate of X feet per hour. He climbed in additional 5000' at a different rate. This rate was 10' per hour less than twice the 1st rate. Which expression represents the number of hours to mountainer climbed?
The correct option for the equation is C.
What is equation?
An equation could be a formula that expresses the equality of 2 expressions, by connecting them with the sign =.
Main Body:
Using distance=rate multiplied by time as the formula,
mountaineer climbed 1,000 feet at a rate of x feet per hour
1000 = xt₁ <--eq.1
"He climbed an additional 5,000 feet at a different rate."
5000 = x't₂ <--eq.2
"This rate was 10 feet per hour less than twice the first rate."
x' = 2x - 10 <--eq.3
We now have 3 equations/expressions to solve for the number of hours:
From eq. 1 and 2:
Total time = t₁ +t₂ = t
t = 1000/x + 5000/x'
but x' = 2x - 10
t = 1000/x + 5000/(2x-10)
t = 1000/x + 5000/[2(x-5)]
t = 1000/x + 2500/(x-5)
Hence correct option is C.

the surface area of the sphere is 105 square inches what is the volume of the sphere use 3.14 for pi
Answer:
The volume of the sphere is \(V\approx101.212 \:in^3\).
Step-by-step explanation:
A sphere is a 3-D figure in which all of the points in a plane are the same distance from a given point, the center of the sphere.
A sphere with radius r has a volume of
\(V=\frac{4}{3} \pi r^3\)
and a surface area of
\(S=4\pi r^2\)
To find the volume of the sphere we use the fact that the surface area of the sphere is 105 \(in^2\) and we use it to find the radius.
\(105=4\pi r^2\\\\4\left(\pi \right)r^2=105\\\\r^2=\frac{105}{4\pi }\\\\\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}\\\\r=\sqrt{\frac{105}{4\pi }},\:r=-\sqrt{\frac{105}{4\pi }}\)
The radius cannot be negative. Therefore,
\(r=\sqrt{\frac{105}{4\pi }}=\frac{\sqrt{105}\sqrt{\pi }}{2\pi }\approx 2.891 \:in\)
Now, that we know the radius we can find the volume
\(V=\frac{4}{3} \pi (2.891)^3=\frac{96.65053\dots \pi }{3}=\frac{303.63661\dots }{3}\approx101.212 \:in^3\)
