Answer:
11 feet
Explanation:
area of trapezoid: 1/2 * (a + b) * hHere given:
a = 15 feetheight = 7.6 feetarea = 98.8 feet²====================
Solving steps:
⇒ 1/2 * (15 + b) * 7.6 = 98.8
⇒ (15 + b) * 7.6 = 197.6
⇒ (15 + b) = 26
⇒ b = 11 ft
Let unknown be x
1/2(x+15.5)(7.6)=98.83.8(x+15.5}=98.8x+15.5=26x=26 .03-15.5x=10.53x≈11ft20 points please help me answer this
Answer:
171 Square Feet
Step-by-step explanation:
We first cut the figure up into smaller parts...
we then use the formula (L x W = A) to find the area
L = Lenth
W = Width
the first rectangle (1)...
15 x 5 = 75
the second figure (2)...
8 x 9 = 72
the third figure (3)...
6 x 4 = 24
now we have to add up all the values to find the area of the entire figure...
75 + 72 + 24 = 171

Answer:
A < C < B = 0.2 < 0.222 < 0.25
Step-by-step explanation:
the best way to do these least to greatest questions is to get them all in the same units so you can compare.
A = [tex]\sqrt{\frac{1}{25} }[/tex]which is [tex]\sqrt{0.04}[/tex] = 0.2
B= 1/4 = 0.25
c=0.22222222.....
now that they are in the same units we see A is the smallest, then C, and then B
If x = 4cosa and y = 5tana, find (x^2/16) - (y^2/25)
[tex]x = 4 \cos(a) [/tex]
[tex] \frac{x}{4} = \cos(a) \\ [/tex]
[tex]( { \frac{x}{4} })^{2} = ({ \cos(a) })^{2} \\ [/tex]
[tex] \frac{ {x}^{2} }{16} = {cos}^{2} (a) \\ [/tex]
_____________________________________________
[tex]y = 5 \tan(a) [/tex]
[tex] \frac{y}{5} = \tan(a) \\ [/tex]
[tex]( { \frac{y}{5} })^{2} = ( { \tan(a) })^{2} \\ [/tex]
[tex] \frac{ {y}^{2} }{25} = {tan}^{2} (a) \\ [/tex]
_____________________________________________
Thus ;
[tex] \frac{ {x}^{2} }{16} - \frac{ {y}^{2} }{25} = \\ [/tex]
[tex] {cos}^{2} (a) - {tan}^{2} (a)[/tex]
A pigpen is to be enclosed using 640 m of fencing along three of its sides, the fourth side being a barn. Determine the dimensions of the pen that will maximize the area (100 PTS + BRAINLIEST)
Answer:
[tex]W_{max}=320m\\ L_{max}=160m[/tex]
Step-by-step explanation:
Since we know we only have 640 feet of fence available, we know that L + W + L = 640, [tex]\implies [/tex] 2L + W = 640. This allows us to represent the width, W, in terms of L: W = 640 – 2L
Remember, the area of a rectangle is equal to the product of its width and length, therefore,
[tex]A_{\rm pigpen}=L(640-2L)\implies 640L-2L^2[/tex]
Notice that, quadratic has been vertically reflected, since the coefficient on the squared term is negative, so the graph will open downwards, and the vertex will be a maximum value for the area.
recall,
[tex]x_{max}=-b/2a[/tex][tex]f(x)_{max}=f(x_{max})[/tex]Since our function is A(L)=640L-2L², we get
a=-2b=640plug in the value of a and b into the first formula:
[tex]L_{max}=-(640)/2(-2)\implies 160 [/tex]
[tex]A(L)_{max}=640(160)-2(160)^2\implies 51200 [/tex]
hence,the dimensions of the pen that will maximize the area are L=160m and W=51200/160=320m
and we're done!
Answer:
width (x) = 160 m
length (y) = 320 m
(refer to the attached diagram)
Step-by-step explanation:
**see attached diagram**
Let x = width of the pig pen
Let y = length of the pig pen
(where length > width)
Given:
Fence = 640 m4th side is the barn⇒ 2x + y = 640 m
⇒ y = 640 - 2x
Area of the pig pen = width × length
⇒ f(x) = xy
Substituting y for y = 640 - 2x:
⇒ f(x) = x(640 - 2x)
= 640x - 2x²
Now we have a function for the area of the pig pen, to find the value of x that will maximize the area, differentiate the function:
⇒ f'(x) = 640 - 4x
Set it to zero and solve for x:
⇒ f'(x) = 0
⇒ 640 - 4x = 0
⇒ 640 = 4x
⇒ x = 160
Substitute the found value of x into y = 640 - 2x to find the length:
⇒ y = 640 - 2(160) = 320
Therefore, the dimensions of the pen that will maximize the area are:
width (x) = 160 mlength (y) = 320 mSolve the equation for x.
-2x = 14

Fundamental theorem of calculus
[tex]g(s)=\int\limits^s_6 {(t-t^4)^6} \, dt[/tex]
Answer:
[tex]\displaystyle g'(s) = (s-s^4)^6[/tex]
Step-by-step explanation:
The Fundamental Theorem of Calculus states that:
[tex]\displaystyle \frac{d}{dx}\left[ \int_a^x f(t)\, dt \right] = f(x)[/tex]
Where a is some constant.
We can let:
[tex]\displaystyle g(t) = (t-t^4)^6[/tex]
By substitution:
[tex]\displaystyle g(s) = \int_6^s g(t)\, dt[/tex]
Taking the derivative of both sides results in:
[tex]\displaystyle g'(s) = \frac{d}{ds}\left[ \int_6^s g(t)\, dt\right][/tex]
Hence, by the Fundamental Theorem:
[tex]\displaystyle \begin{aligned} g'(s) & = g(s) \\ \\ & = (s-s^4)^6\end{aligned}[/tex]
- At a school carnival, 8 out of 32 tickets sold were early-admission tickets. What
percentage of the tickets were early-admission tickets?
Answer:
25 Percent of tickets were early admission.
Step-by-step explanation:
We apply the percentage formula to solve this problem.
Total Ticket Amount * Percentage = Early tickets
We plug in our values
32 * x/100 = 8
Simplify
X=25
Answer:
25%
Step-by-step explanation:
8 out of 32 can be simplified to 1 early admission for every 4 tt (total tickets). 1/4 can be changed into a decimal which is .25, and .25*100 is 25%

a. Which cost category varies the least among the different types of colleges? Can you explain why this category varies so little?
b. Ignoring the "other expenses" category, the general trend is for all categories to cost more as you look down the chart from two-year public colleges to four-year private colleges. However, one category is an exception to this trend. Which category? Can you explain why?
The question indicated above speaks to expense analysis for anonymous colleges. See the details of the analyses below.
From the pictorial representation, which cost category varies the least among the different types of colleges?The cost category that varies the least amongst the various types of colleges is Books and supplies. Notice that at no point did it go below 1,097, nor above, 1,350.
The categories that do not cost more as one goes down the chart (apart from other expenses) are:
Books and supplies and Transportation.Books and supplies went from: $1,350 to $1,107, to 1,107, and then to 1097. Hence decreasing gradually over time.
Transportation also decreased over time starting out from $2,152, to $2,099, to 2,099 and then flatting out at $1,571.
It may be explained that the cost of books is on the decline as more and more people prefer online reading while the cost of transportation is declining as more and more students use their cars or vehicles to the college, hence driving down the cost of transportation.

7. If (0.2)x = 2 and log 2 = 0.3010, then the value of x to the nearest tenth is?
(0.2)x = 2.
Taking log on both sides
log (0.2)x = log 2.
x log (0.2) = 0.3010, [since log 2 = 0.3010].
x log (2/10) = 0.3010.
x [log 2 - log 10] = 0.3010.
x [log 2 - 1] = 0.3010,[since log 10=1].
x[-0.699] = 0.3010.
x= 0.3010/-0.699.
x= = -0.4306….
x= = -0.4.
(0.2)x = 2.
Taking log on both sides
log (0.2)x = log 2.
x log (0.2) = 0.3010, [since log 2 = 0.3010].
x log (2/10) = 0.3010.
x [log 2 - log 10] = 0.3010.
x [log 2 - 1] = 0.3010,[since log 10=1].
x[-0.699] = 0.3010.
x = 0.3010/-0.699
x = -0.4306
x= -0.4 (nearest tenth)
A business owner wants a smaller version of the logo (picture attached) to be on the door of her business. The door is 7 feet tall and 3 feet wide There should be 6 inches of empty space to the left side of the logo and 6 inches of empty space on the right side of the logo.
Based off the logo (picture attached), what should be the total width, in feet, of the logo on the door?
Based off the logo (picture attached), what should be the total height, in feet, of the logo on the door?
Answer:
Clair, since there isn't an attached picture, we don't know some info
Step-by-step explanation:
but here is how you can figure this out....
they tell use to give 6 inches on each side of the door, so the total width of the logo can be 2 feet wide. Because the door is 3 feet wide. Now use that to find the height. find the height to width ratio of the logo, so if the logo is 4 feet wide and 6 feet tall it's 6/4 or 1.5 ratio, use that and multiply by the 2 that we know the width can be on the door. so 2*1.5 = 3. the height of the logo would be 3 feet tall and 2 feet wide on the door. see?
just find the ratio of the logo, and multiply that by 2 :) to find the height on the door, got it?

Please help! Determine the function which corresponds to the given graph.
By identifying that it is a translation of the natural logarithm, we see that the function is:
g(x) = ln(x - 5).
How to determine the function?
We can see that the function has a logarithmic behavior. We know that the function:
f(x) = ln(x)
Has an asymptote at x = 0, and is equal to 0 for x = 1.
For our function, we can see that the asymptote is at x = 5 and the zero is at x = 6. So the graphed function seems to be the natural logarithm translated 5 units to the right.
Then the function graphed is:
g(x) = f(x - 5) = ln(x - 5)
