g Farmer Violet wants to enclose one 990 square foot rectangular area of land using fencing. One side will use special fencing costing $12 per foot. The remaining three sides of fencing will be formed using standard fencing costing $10 per foot. Find the dimensions of the corral that would minimize the cost of the fencing required for this project, rounded (if necessary) to the nearest hundredth of a foot
Answer:
Sides of the rectangular area:
x = 30 f
y = 33 f
Step-by-step explanation:
Let´s call x and y the sides of the rectangular area
A = x*y = 990 y = 990/x
The function cost is:
C = Costs ( sides x) + costs ( sides y )
Cost of sides x = 12*x + 10x
Cost of sides y = 10*y + 10 *y = 2*10*y = 20*y
C = 12*x + 10*x + 20*y = 22*x + 20*y
The function cost as function of x is:
C(x) = 22*x + 20*(990/y) = 22*x + 19800/x
Tacking derivative on both sides of the equation:
C´(x) = 22 + [ - 19800/x²]
C´(x) = 0 22 - 19800/x² = 0
Solving for x
22*x² - 19800 = 0
22x² = 19800
x² = 19800/22 = 900
x₁,₂ = ± 30 We dismiss negative root ( we never have negative lenghts)
Then x = 30 f
And y = 990 / 30 y = 33
To see if x = 30 is a minimum for function C(x) we evaluate the second derivative.
C´´(x) = 2*x* 19800/x⁴
C´´ (x) = 39600/x³ so C´´ is always greater than 0 then C (x) has a minimum at x = 30
Sides of the rectangular area are:
x = 30
y = 33
If f(x) = k(x - 2)^2, where k is positive, what is the effect on the graph of f(x) as k increases
Answer:
The value of k determines where the parabola is on the y-axis. In other words, its "height". If k we're to be positive, the parabola would move to the positive side of y-axis, not negative.

Solve for x. 20x + 5 =5x+65
Answer:
x = 4
Step-by-step explanation:
subtract 5 from all sides
20x+5-5=5x+65-5
simplify
20x=5x+60
subtract 5x from both sides
20x-5x=5x+60-5x
simplify again
15x=60
Divide both sides by 15
15x/5 = 60/15
lastly simplify to get your answer of
x = 4
line parallel to y=8-1/8x
Answer:
Y = (-1/8) X + C is the equation of a line parallel to y=8-1/8x
Step-by-step explanation:
Complete question.
Find the line parallel to y=8-1/8x
Solution
For two lines to be parallel to each other it is essential that their slopes must be same
For any line of the form
Y = mX +b
m is the slope
Here the equation of given line is y=8-1/8x
on rearranging, we get
Y = (-1/8) X + 8
here m = (-1/8)
Hence, line parallel to y=8-1/8x is any line with slope equal to (-1/8)
Or we can say that equation of parallel line would be
Y = (-1/8) X + C
Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB = 24
and AD = 12, what is the length of AC?
A
12
D
24
Answer: x=48
Step-by-step explanation:
The length AC of the right-angle triangle will be 48 units.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
According to the hypotenuse-leg (HL) principle, a right triangle is harmonious if each of its third side and legs are congruent with its equivalent hypotenuse and legs in another right triangle. The HL theorem proves that these triangles are identical.
AC / AB = AB / AD
AC / 24 = 24 / 12
AC = 48 units
The length AC of the right-angle triangle will be 48 units.

Using the perimeter formula of a rectangle, P = 21+2w, find the perimeter of the rectangle giver
the length is 42 feet and the width is 26 feet
I
Answer:
-21
Step-by-step explanation:
the formula for the perimeter of a rectangle is 2l+2w. which means twice the length and twice the width added to together.
if you mean this:
x=21+2x
minus x on both sides
0=21-x
add 21 on both sides
21=-x
x=-21
than you subsitute
2×-21=-42
-42+21= -21

A 20-minute consumer survey that included a $5 Starbucks gift card was emailed to 500 adults aged 25-34. The survey resulted in 65 responses. The same 20-minute consumer survey was emailed to 500 adults aged 25-34 without the Starbucks gift card. The survey resulted in 45 responses. We would like to know if the inclusion of a Starbucks gift card led to any change in survey response rate. Which of the following hypotheses should be used?
A. Null Hypothesis: mul (average number of responses with Starbucks gift card)<= muo(average number of responses without Starbucks gift card) Alternative Hypothesis: mu1 ( average number of responses with Starbucks gift card)> muo(average number of responses without Starbucks gift card)
B. Null Hypothesis: mu1 (average number of responses with Starbucks gift card)= mud (average number of responses without Starbucks gift card) Alternative Hypothesis: mu1 ( average number of responses with Starbucks gift card) \= mul ( average number of responses without Starbucks gift card) * \= means "not equal to"
C. Null Hypothesis: pi1 (rate with Starbucks gift card)= pi2 (rate without Starbucks gift card) Alternative Hypothesis: pi1 (rate with Starbucks gift card) (= pi2 (rate without Starbucks gift card) * \= means "not equal to"
D. Null Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card)<=0 Alternative Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card) > 0
Answer:
D. Null Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card)<=0 Alternative Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card) > 0
Step-by-step explanation:
The test described above test the difference in proportion :
With Starbucks gift card :
x1 = 65 n1 = 500
Phat 1 = x1 / n1
Phat 1 = 65 /500 = 0.13
Phat1
Without Starbucks gift card :
x2 = 45 n2 = 500
Phat1 = x2 / n2
Phat 2 = 45 / 500 = 0.09
To test the difference in proportion :
Phat 1 > Phat 2 (alternative)
Null takes the stance that there is no difference in proportion
Phat1 - phat2 <=0
Alternative claims that there is difference on proportion such that phat 1 is greater than phat 2
Phat 1 - phat > 0
