The differentiation of the function g(t) = 7/t⁴ will be equal to g¹(t)=-28/t⁵
What is differentiation?
The method of determining the derivative, or rate of change, of a function in mathematics.is termed as the differentiation.
Given that:-
[tex]g(t)= \dfrac{7}{t^4}[/tex]
The derivative will be calculated as:-
[tex]g'(t)=7 \dfrac{d}{dt}(t^{-4})\\\\\\g'(t)=7\times (-4t^{-5})\\\\\\g'(t)=\dfrac{-28}{t^5}[/tex]
Therefore the differentiation of the function g(t) = 7/t⁴ will be equal to g¹(t)=-28/t⁵

Answer:
a = 63
b = 117
c = 63
Step-by-step explanation:
The sum of interior angles in a triangle is = 180
so the measure of a:
85 + 32 + a = 180 add like terms
117 + a = 180 subtract 117 from both sides
a = 63
a and be are supplementary angles so their sum is equal to 180
180 - 63 = 117 is the b's value
since a and c are on a pair of parallel lines, their value must be equal therefore the value of c is also 63
Serenity earned a grade of 39% on her multiple choice science final that had a total of
200 problems. How many problems on the final exam did Serenity answer correctly?
Answer:
78
Step-by-step explanation:
The number of correct problems is found by multiplying the percentage that were correct by the total number of problems.
__
number correct = fraction correct × number of problems
number correct = 0.39 × 200 = 78
Serenity answered 78 problems correctly.

Additional comment
The symbol % is fully equivalent to /100. That is 39% = 39/100 = 0.39 (pronounced "thirty-nine hundredths"). Using a percent symbol is just another way to write a fraction.

C = π (3.14) * 5
= about 15.71 m
A. 15.71 m
Answer:[tex]5\pi[/tex]
Step-by-step explanation:The circumference is pi times the diameter. If you want a proof you can find it online with a quick search. This applied here means that since the diameter is 5, the circumference is 5*pi or rather 5pi.
At the beginning of the month, a rain barrel contained 12 ounces of water. At the end of the month there are 814 cups of water in the rain barrel.
How many cups of rain water were added to the barrel during the month?
Enter your answer as a mixed number in simplest form by filling in the boxes.
Upon searching for your question, I believe there are 8 [tex]\frac{1}{4}[/tex] cups, and not 814 cups.
Answer: 6 [tex]\frac{3}{4}[/tex] cups of water
Step-by-step explanation:
First, we will turn 12 ounces into units of cups.
12 / 8 = 1.5 cups
Now, we will subtract the start of the month from the end of the month.
8.25 cups - 1.5 cups = 6.75 cups
Lastly, we will turn it into a mixed number.
.75 = [tex]\frac{3}{4}[/tex]

a) A × B is the Cartesian product of A and B, given by the set

Then for A = {4, 6, 8} and {4, 5, 6}, we have the product
A × B = {(4, 4), (4, 5), (4, 6), (6, 4), (6, 5), (6, 6), (8, 4), (8, 5), (8, 6)}
b) The power set of a set X is the set containing all subsets of X. I'm not sure what you're asking to find the power set of, though. Hopefully it's not of A × B, since that would contain 2⁹ = 512 elements...
Instead I'll assume you mean a simpler set, such as A ∩ B. The intersection of A and B is
A ∩ B = {4, 6, 8} ∩ {4, 5, 6} = {4, 6}
and has only 2 elements, so its power set has 2² = 4 elements (much more manageable!) and is the set

Orange traffic cones comes in a variety of sizes. Approximate the volume, in cubic inches, of a traffic cone
that has a height of 2 feet and a diameter of 16 inches. Round your answer to the nearest tenth. Use 3.14
for a.
Answer:
V = 1607.7 in^3
V = 0.94 ft^3
Step-by-step explanation:
To find the volume of a traffic cone, use the formula for the volume of a cone: (1/3)*π*h*r^2
h = height
r = radius of cone
Step 1: determine variables and units
2 feet = 24 inches
diameter = 2 * radius
radius = (1/2) * diameter = (1/2)*16 in = 8 inches
Step 2: determine volume
V = (1/3)*π*h*r^2
V = (1/3)*3.14*24*(8)^2
V = 1607.7 in^3
Optional step 3: determine volume in ft^3
h = 2 ft
r = 0.67 ft
V = (1/3)*π*h*r^2 = (1/3)*3.14*2*(0.67)^2
V = 0.94 ft^3

Show all work. Find the measure of <1. Show all work.
Its in the picture below.
The value of x is 7 and the measure of ∠1 is 99
How to solve for x?The given parameters are:
∠NMQ = 5x + 19∠MQN = 8x - 11∠QNM = 11x + 4The sum of angles in a triangle is 180.
So, we have:
5x + 19 + 8x - 11 + 11x + 4 = 180
Evaluate the like terms
24x = 168
Divide both sides by 24
x = 7
Hence, the value of x is 7
How to determine the measure of ∠1?The angles on a straight line add up to 180.
This means that:
∠1 + ∠QNM = 180
Subtract ∠QNM from both sides
∠1 = 180 - ∠QNM
Substitute ∠QNM = 11x + 4
∠1 = 180 - 11x - 4
Substitute x = 7
∠1 = 180 - 11 * 7- 4
Evaluate
∠1 = 99
Hence, the measure of ∠1 is 99

Answer:
[tex]x=\dfrac{2}{3},-\dfrac{3}{2}[/tex]
Step-by-step explanation:
Given equation:
[tex]6x^2+5x-6=0[/tex]
First, factor the left side of the given equation.
To factor a quadratic in the form [tex]ax^2+bx+c[/tex] find two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]:
[tex]\implies ac=6\cdot-6=-36[/tex]
[tex]\implies b=5[/tex]
So the two numbers are: 9 and -4
Rewrite [tex]b[/tex] as the sum of these two numbers:
[tex]\implies 6x^2+9x-4x-6=0[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies 3x(2x+3)-2(2x+3)=0[/tex]
Factor out the common term [tex](2x+3)[/tex]:
[tex]\implies (3x-2)(2x+3)=0[/tex]
To solve for x:
[tex]\begin{aligned}\implies (3x-2) & =0 & \implies (2x+3) & = 0\\3x & = 2 & 2x & = -3\\x & = \dfrac{2}{3} & x & = -\dfrac{3}{2}\end{aligned}[/tex]
Therefore:
