find a function f such that f '(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f.
A function f such that f '(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f is f(x) = 3x^4/4 + 729/4.
In the given question, we have to find a function f such that f'(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f.
The given function is f'(x) = 3x^3.
No integrating on both side,
f(x) = [tex]\int3x^3dx[/tex] + C
f(x) = 3x^4/4 + C
As given, the line 81x + y = 0 is tangent to the graph of f.
So, slope at point of tangent; f'(x) = -81
So, 3x^3 = -81
Divide by 3 on both side, we get
x^3 = -27
Taking cube root on both side, we get
x = -3
So putting the value of x in 81x + y = 0, we get
y = 243
Thus, f(x) passes through (-3, 243).
So, 243 = 3/4(81) + C
Multiply by 4 on both side, we get
972 = 243 + 4C
Subtract 243 on both side, we get
4C = 729
Divide by 4 on both side, we get
C = 729/4
So, f(x) = 3x^4/4 + 729/4

the work done is equal to the force applied (500 lb) multiplied by the distance (100 ft), resulting in 500 ft-lb of work done.
A force applied across a distance is what is referred to as work.
In this problem,
the force applied is the weight of the cable (5 lb/ft) multiplied by the length of the cable (100 ft).
Therefore, the work done is equal to the force applied (500 lb) multiplied by the distance (100 ft), resulting in 500 ft-lb of work done.Work is a force applied across a distance, and it is measured in a unit of energy called foot-pounds. In this problem, the force applied is the weight of the cable (5 lb/ft) multiplied by the length of the cable (100 ft). Therefore, the work done is equal to the force applied (500 lb) multiplied by the distance (100 ft), resulting in 500 ft-lb of work done. This means that 500 ft-lb of energy must be expended in order to move the cable 100 ft. This energy can be provided by a variety of sources, such as human labor, a motor, or some other mechanism.

Using the normal distribution, the middle 50% would be expected to be in the range of 250 to 270 days.
Using the central limit theorem, for the samples of 36, the middle 50% would be expected to be in the range of 258 to 262 days.
What is normal distribution theorem?A sort of continuous probability distribution for a real-valued random variable is the normal distribution or the Gaussian distribution.
Normal Distribution of Probabilities
The z-score formula, which for a measure X, in a set with mean and standard deviation, is given by: can be used to address problems with normal distributions.
Z = (X - μ)/σ
The z-score calculates the measure's standard deviation from the mean.
A p-value, or percentile of X, is assigned to each z-score.
Mean (μ) = 260.
Standard deviation (σ)= 15 .
The normal distribution is symmetric, which means that the middle 50% is between the 25th percentile and the 75th percentile.
The 25th percentile is X when Z has a p-value of 0.25, so X when Z = -0.675.
The 75th percentile is X when Z has a p-value of 0.75, so X when Z = 0.675.
Lower bound:
Z = (X - μ)/σ
⇒ -0.675 = (X - 260)/15
⇒ X - 260 = -0.675*15
⇒ X - 260 = -10.125
⇒ X = 260 - 10.125
⇒ X ≈ 250
Upper bound:
Z = (X - μ)/σ
⇒ 0.675 = (X - 260)/15
⇒ X - 260 = 0.675*15
⇒ X - 260 = 10.125
⇒ X = 260 + 10.125
⇒ X ≈ 270
The middle 50% of pregnancies would be in the range of 250 to 270 days.
For sample of 36: By the Central Limit Theorem, the standard deviation of the sampling distribution of sample means of size n is given by .
Sample of 36, thus n=36, s=15/√36
⇒ s=15/6
⇒ s=2.5
Lower bound:
Z = (X - μ)/s
⇒ -0.675 = (X - 260)/2.5
⇒ X - 260 = -0.675*2.5
⇒ X - 260 = -1.69
⇒ X = 260 - 1.69
⇒ X ≈ 258
Upper bound:
Z = (X - μ)/s
⇒ 0.675 = (X - 260)/2.5
⇒ X - 260 = 0.675*2.5
⇒ X - 260 = 1.69
⇒ X = 260 + 1.69
⇒ X ≈ 262
The middle 50% of pregnancies would be in the range of 258 to 262 days.

i need it rnn
and if u could plot the point too thats good
js those for now tyy
Step-by-step explanation:
5.
y = 3
yes, that's it for this here too.
it means that any value for x is valid, and all have the assigned y value 3.
6.
remember, the usual equation for a line is
y = ax + b
"a" being the slope, "b" the y-intercept (the y-value when x = 0).
we see the y-value for x = 0 is 3. that is "b".
for the slope we need 2 points and calculate the x- and y- coordinate differences.
always look for points with integer coordinates.
I see e.g. (0, 3) and (3, 2).
x changes by +3 (from 0 to 3).
y charges by -1 (from 3 to 2).
the slope "a" = -1/+3 = -1/3
the equation is then
y = (-1/3)x + 3
7.
we do exactly the same things.
we see the y-value for x = 0 is +1. that is "b".
I see e.g. these points : (0, 1) and (3, 2).
x changes by +3 (from 0 to 3).
y changes by +1 (from 1 to 2).
the slope "a" is +1/+3 = 1/3.
the equation is
y = (1/3)x + 1
8.
and again the same things.
we see the y-value for x = 0 is +3. that is "b".
I see e.g. these points : (0, 3) and (-3, 0).
x changes by -3 (from 0 to -3).
y changes by -3 (from 3 to 0).
the slope "a" is -3/-3 = 3/3 = 1.
the equation is
y = x + 3
Given the equation a line y+9=-3(x-4) Determine the characteristics of the line.
Answer:
Step-by-step explanation: y+9=-3(x-4)......given equation
This equation can be expanded further and simplified
y+9=-3x+12
We want to put the equation into the form y=mx+b so we can read its characteristics
To do this we need to get y on its own. We must take 9 from both sides
y+9-9=-3x-9+12
y=-3x+3
The equation has a gradient or slope or m =-3 and it cuts the y-axis at +3 or is the yintercept
Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 18)(0,18) and (3, 6174)(3,6174).
The exponential function in the form y = ab^x is y = 18(7)^x
How to determine the exponential function in the formFrom the question, we have the following parameters that can be used in our computation:
Points: (0, 18) and (3,6174).
The above can be represented as
(x, y) = (0, 18) and (3,6174).
An exponential function is represented as
y = ab^x
Where
a = y when x = 0
This means that
a = 18
So, we have
y = 18b^x
At (3,6174), we have
6174 = 18b^3
So, we have
343 = b^3
Take the cube root of both sides
b = 7
This means that
y = 18(7)^x
Hence, the function is y = 18(7)^x

What is the inverse function for -2f(x+5)-4
Answer:
Read carefully below
Step-by-step explanation:
In general, the inverse of a function f(x) is a function g(x) such that f(g(x)) = g(f(x)) = x for all values of x in the domain of f(x) and g(x). To find the inverse of a function, we need to switch the input and output variables and solve for the new output variable.
In this case, we are given the function -2f(x+5)-4. To find the inverse of this function, we need to switch the input and output variables and solve for the new output variable, which we will call y. We can do this by first moving all the terms to one side of the equation, and then solving for y:
-2f(x+5) - 4 = y
-2f(x+5) = y + 4
f(x+5) = (y + 4) / -2
This is the inverse function of -2f(x+5)-4. However, keep in mind that not all functions have inverses. In particular, a function must have the property that it is one-to-one (i.e. it maps unique inputs to unique outputs) in order to have an inverse. It is not clear from the given information whether the function -2f(x+5)-4 is one-to-one, so it is possible that it does not have an inverse.

find the sum of 2 over 3 + negative 1 over 3
Answer:
2/3 + -1/3 = positive 1/3
Answer:
To find the sum of 2/3 + (-1)/3, you can first convert the fraction to an equivalent fraction with a common denominator. In this case, the common denominator would be 3. 2/3 can be written as 2 x (3/3) = 2/3 and -1/3 can be written as -1 x (3/3) = -1/3. Then, you can add the numerators and the denominator will remain the same. So, the sum of 2/3 + (-1)/3 is 1/3.

Step-by-step explanation:
Note:
[tex]P=[/tex] Perimeter
[tex]L=[/tex] Length
[tex]W=[/tex] Width
The perimeter of a rectangle is the sum of all its sides.
We can say
[tex]P=L+L+W+W[/tex]
Which simplifies to
[tex]P=2L+2W[/tex]
This is the equation to find the perimeter of a rectangle.
We are given the perimeter which is 42.
We are also given that the length is the sum of twice its width and 3.
So we can write
[tex]42=2L+2W\\L=2W+3[/tex]
Lets solve using substitution.
Substitute [tex]L=2W+3[/tex] into the first equation.
[tex]42=2W+2(2W+3)[/tex]
Expand the right side of the equation then simplify.
[tex]42=2W+4W+6\\42=6W+6[/tex]

Which of the following choices lists the values of the side lengths of an isosceles triangle with a hypotenuse = 8?
8,8, and 16
2, 4, and 8
4√2, 4√2, and 8
None of these choices are correct.
The set of the values of the side lengths of an isosceles triangle that has a hypotenuse that is 8 units long is: C. 4√2, 4√2, and 8.
What is an Isosceles Triangle?An isosceles triangle is a type of triangle that has two sides that are of the same length, while the third side has a different length.
What is the Hypotenuse of a Triangle?The hypotenuse is found in a triangle that has a right angle. This means the triangle is a right triangle, and therefore, according to the Pythagorean theorem, the square of the length of the hypotenuse is equal to the sum of the squares of the other legs of the triangle.
Considering the definition given above, it means the right triangle we are looking for must be a right triangle is isosceles, which hast two equal sides and an hypotenuse that is 8 units long.
The values of the set of lengths, 2, 4, and 8 cannot be the isosceles triangle because they have three different side lengths.
8,8, and 16 do not conform to the Pythagorean Theorem because:
16² ≠ 8² + 8²
4√2, 4√2, and 8 conform to the Pythagorean Theorem because:
8² = (4√2)² + (4√2)²
64 = 64
Therefore, the values of side lengths are: C. 4√2, 4√2, and 8.

AXYZ is similar to ALMN. Angle Y is 89
degrees and Angle N is 32 degrees.
Record the measures for each angle in
the diagram.
The measurement of angles △XYZ are ∠X = 59°, ∠Y = 89°, and ∠Z = 32°.
The measurement of angles △LMN are ∠L = 59°, ∠M = 89°, and ∠N = 32°.
What is angle?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
Given that, △XYZ and △LMN are similar triangle.
Since the triangles are similar, thus the measurement of triangles are similar.
Therefore,
∠X = ∠L, ∠Y = ∠M, ∠Z = ∠N.
∠Y = ∠M = 89° and ∠Z = ∠N = 32°.
The sum of all interior angles of triangle is 180°.
∠X + ∠Y + ∠Z = 180°
∠X + 89° + 32° = 180°
∠X + 121° = 180°
Subtract 121° from both sides:
∠X = 59°
∠X = ∠L = 59°.

What is the answer to 19(2m−16)=13(2m+4)
Answer:
m = -21.
Step-by-step explanation:
To solve this equation, we can use the distributive property to expand the left side and the right side of the equation:
19(2m - 16) = 13(2m + 4)
38m - 304 = 26m + 52
Then we can combine like terms on both sides of the equation to obtain:
38m - 26m = 52 - 304
12m = -252
Finally, we can divide both sides of the equation by 12 to find the value of m:
12m / 12 = -252 / 12
m = -21
Therefore, the value of m that satisfies the equation is m = -21.
