Answer:
[tex]g=6x+18[/tex]
Step-by-step explanation:
From the question we are told that:
Function
[tex]f(x)=x^3+9x^2−81x+14[/tex]
Generally 1st derivative f'(x) of Fuction f(x) is
[tex]f'(x)=3x^2+2*9(x)-81[/tex]
[tex]f'(x)=3x^2+18(x)-81[/tex]
Generally 2nd derivative f''(x) of Fuction f(x) is
Where
[tex]f''(x)=g[/tex]
Therefore
[tex]g=3x^2+18(x)-81[/tex]
[tex]g=2*3x^1+18[/tex]
[tex]g=6x+18[/tex]
A farmer wants to know the effect of using various amounts of fertilizer in relation to the yield of his crops. He subdivided a portion of his land into 10 separate, but essentially equal, plots. He divided the land so that all of the plots had equal exposure to sun, rain, and other environmental conditions. He randomly selected 2 of the 10 plots and spread 2 pounds of fertilizer over each of them. Then he randomly selected 2 of the remaining plots and spread 3 pounds of fertilizer over each of them. He continued with the last sets of plots in the same manner, spreading 4, then 5, then 6 pounds of fertilizer over each of them. Assume the conditions for regression inference have been satisfied. To construct the 90% confidence interval for the true slope of the population regression equation relating amount of fertilizer to yield.

THANK you...
The area of the rectangle to the nearest square centimeter will be 15 square centimeters. Then the correct option is E.
What is the area of the rectangle?Let W be the rectangle's width and L its length.
The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be
Area of the rectangle = L × W square units
A golden rectangle has a length of 5 cm. Then the width of the rectangle is given as,
W = 5 - 2
W = 3 cm
Then the area of the rectangle will be given as,
A = 5 x 3
A = 15 square centimeters
The area of the rectangle to the nearest square centimeter will be 15 square centimeters. Then the correct option is E.

Two boats started to move towards each other from two docks, located 30 miles apart. One boat moved at a speed of 3 miles per hour, the other moved twice as fast. How soon will the boats meet?
Answer:
3.333 hours
Step-by-step explanation:
Given the total distance is 30 miles, and boat 1 travels at 3 mph and boat 2 travels at 6 mph, and the time for both is the same. Distance is speed S times time T so
30 = D(boat 1) + D(boat 2)
30 = (S1 * T) + (S2 * T)
30 = 3T + 6T
30 = 9T
3.333 = T

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Expression : 4y

In the first quadrant ,you start at 4,6 and move 3 units right and 1 unit down ,what point will u end up
Answer:
You end up at point (7,5).
Step-by-step explanation:
Starting point:
The coordinates of the starting point are: x = 4, y = 6.
So
(4,6).
Move 3 units right:
Moving 3 units right is adding 3 to the x-coordinate. So
x = 4 + 3 = 7
(7,6).
Move 1 unit down:
Moving 1 unit down is subtracting 2 from the y-coordinate. So
y = 6 - 1 = 5.
You end up at point (7,5).
If you place a 35-foot ladder against the top of a 31-foot building, how many feet will the bottom of the ladder be from the bottom of the building? Round to the nearest tenth of a foot.
Answer:
4ft
Step-by-step explanation:
The bottom of the ladder will be 16.25 feet from the bottom of the building.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
As per the situation, we create a right triangle as shown.
Let x be the distance from the bottom of the building to the bottom of the ladder.
Using Pythagoras's theorem, then, we have:
x² + 31² = 35²
Simplifying this equation, we get:
x² = 35² - 31²
x² = 264
x = 16.25 (rounded to the nearest tenth of a foot).
Therefore, the bottom of the ladder will be 16.25 feet from the bottom of the building.

As of 2018, Apple had 5 billion outstanding shares. The stock price is roughly $200.
A) How much is Apple worth?
B) If all tangible assets total $1 Billion, what
represents the rest of Apple's worth?
Answer:
Therefore, the value of the company is $ 1,000,000,000,000, that is, a trillion dollars. In turn, if the tangible assets of the company are worth 1 billion, all the other intangible assets of the company are worth 999 billion.
Step-by-step explanation:
Given that as of 2018, Apple had 5 billion outstanding shares whose stock price is roughly $ 200, to determine the value of the company and determine, if all tangible assets total $ 1 Billion, what represents the rest of Apple's worth, the following calculations must be done:
5 billion = 1,000,000,000
5,000,000,000 x 200 = X
1,000,000,000,000 = X
1 trillion = 1000 billions
1000 - 1 = 999
Therefore, the value of the company is $ 1,000,000,000,000, that is, a trillion dollars. In turn, if the tangible assets of the company are worth 1 billion, all the other intangible assets of the company are worth 999 billion.
in new england 47% of the houses have a garage and 36% of the houses have a garage and a backyard what is the probability that a house has a backyard given that has a garage probs and stats
Answer:
The probability that a house has a backyard given that has a garage is 76.60%.
Step-by-step explanation:
Given that in New England 47% of the houses have a garage and 36% of the houses have a garage and a backyard, to determine what is the probability that a house has a backyard given that has a garage the following crossed multiplication must be performed:
47 = 100
36 = X
(36 x 100) / 47 = X
3,600 / 47 = X
76.5957 = X
Therefore, the probability that a house has a backyard given that has a garage is 76.60%.

Answer:
x = 6/√3
y = 3/√3
Step-by-step explanation:
For a triangle rectangle with a known angle θ, we have the relations:
Sin(θ) = (opposite cathetus)/(hypotenuse)
Cos(θ) = (adjacent cathetus)/(hypotenuse)
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
For this triangle, we know an angle:
θ = 60°
And the opposite cathetus measures 3 units.
The adjacent cathetus is y.
The hypotenuse is x.
To find the value of x, we can use the Sin equation:
Sin(60°) = 3/x
x = 3/sin(60°) = 3.46 = 3*2/√3 = 6/√3
And we can use the Tan relation to find the value of y.
Tan(60°) = 3/y
y = 3/Tan(60°) = 1.73 = 3/√3
For x he didn't divide by √3, while for y he multiplied by √3 instead of dividing by √3.
