which inequality does the graph represent?
A. y<-x-1
B. y<-x+1
C. y
D. y
Answer:
B) y < -x + 1
Step-by-step explanation:
you can see from the x-and-y intercepts that the equation of this line is:
y = -x + 1
now you must determine whether the equal sign should be replaced with '<' or '>'
you can use the point (0,0) to see if that makes y > -x + 1 true or false:
0 > 0+1 This is False
so the answer should be: y < -x + 1
The population of rabbits on an island is growing exponentially. In the year 1992, the
population of rabbits was 220, and by 1997 the population had grown to 400. Predict
the population of rabbits in the year 2000, to the nearest whole number.
Answer:
572.6
Step-by-step explanation:
400 = 220 [tex]x^{5}[/tex]
ln(400/220) = 5 ln(x)
ln(x) = .1195
x = [tex]e^{.1195}[/tex]
x = 1.127
Y = 220[tex](1.127)^{8}[/tex]
Y= 572.6
Determine the number of bars and bar width in the histogram using the following 50 numbers. 26 39 39 22 18 8 52 69 15 2 60 87 98 10 39 50 3 41 62 29 78 97 60 72 65 15 24 14 14 98 50 60 17 82 44 52 91 77 52 71 9 98 36 93 43 86 87 20 93 98
Answer:
10 bars ; width 10
Step-by-step explanation:
Reordering the data given :
2, 3, 8, 9, 10, 14, 14, 15, 15, 17, 18, 20, 22, 24, 26, 29, 36, 39, 39, 39, 41, 43, 44, 50, 50, 52, 52, 52, 60, 60, 60, 62, 65, 69, 71, 72, 77, 78, 82, 86, 87, 87, 91, 93, 93, 97, 98, 98, 98, 98
To know the number of bars and width to use, we need to know the range of the data, from there we can decide the most appropriate width and also the number of bars we get using the width ;
Range = 98 - 2 = 96
By extending the width slightly on either side, we have 0, 100.
If we start from the origin, 0 ; and the maximum data point = 98 ; by slightly extending the width to 100 ; we could make use of a very reasonable width of 10; which is easier to work with than lesser width values ;
Now our range = 100 - 0 = 100
Width = 10
Number of bars = range / bar width
= 100 / 10
= 10 bars
What is the approximate sector area of a sector defined by minor arc CB?
Answer:
d. 7.5 cm²
Step-by-step explanation:
Area of sector = central angel/360 × πr²
Central angle = 180° - 84° = 96° (supplementary angles)
BA = radius (r) = ½(6) = 3 cm
Plug in the values
Area of sector = 96/360 × π*3²
= 7.53982238
= 7.5 cm² (nearest tenth)

Find the quotient.
5^-3/5^-1
Answer:
3/35
Step-by-step explanation:
A technical machinist is asked to build a cubical steel tank that will hold of water. Calculate in meters the smallest possible inside length of the tank. Round your answer to the nearest .
Answer:
The smallest possible length is 0.83m
Step-by-step explanation:
Given
[tex]Volume = 565L[/tex]
Required
The smallest length of the tank
Since the tank is cubical, then the volume is:
[tex]Volume = Length^3[/tex]
This gives:
[tex]565L= Length^3[/tex]
Express as [tex]m^3[/tex]
[tex]\frac{565m^3}{1000} = Length^3[/tex]
[tex]0.565m^3 = Length^3[/tex]
Take cube roots of both sides
[tex]0.8267m = Length[/tex]
Rewrite as:
[tex]Length = 0.8267m[/tex]
Approximate
[tex]Length = 0.83m[/tex]
HELPPPPOOOPPPPOPPPPPPPP
Answer:
Your answer would be B
Step-by-step explanation:
So right away you can get rid of a and d since they are positive numbers, there is no positive numbers in the graph were the line is.
So we know that the y-intercept is -2 (as you can see the line pass through (0,-2))
And we know the y intercept is -8 (since the line pass through (-8,0))
so you are left with b and c, c is incorrect because the -2 goes through the y-intercept not the x.
The right choice is b, it states that the x-intercept -8 pass through the line, the y-intercept is -2
Your welcome and hoped this helped!
Evaluate the function.
Answer:
f(-1) = 5
Step-by-step explanation:
To "evaluate the function f(x) = -x^2 + 6 at x = -1, we substitute -1 for x in each instance:
f(-1) = -(-1)^2 + 6
According to order of operations rules, exponentiation must be performed before multiplication or division. '-(-1)^2' thus becomes -1, and so
f(-1) = -(-1)^2 + 6 = -1 + 6 = 5.
Thus, f(-1) = 5

(2 points) Part B: Write the measurements of Sides AB, BC, and CD of the correct net. (4 points) Part C: What is the surface area of the prism? Show your work. (4 points)
9514 1404 393
Answer:
net A is correctsurface area is 98.4 square inchesStep-by-step explanation:
Part A:
The two right-angle corners of the triangular bases are at either end of the same edge. This is only shown correctly in Net A.
__
Part B:
See the attached annotated diagram. Dimensions are in inches.
__
Part C:
The total surface area is the sum of the three central rectangles of the net and the two triangles. As shown in the attached, the two triangles can be considered as one rectangle of dimensions 3 in by 4 in.
The total area is ...
Surface area = base area + face area
= (3 in)(4 in) + (3 + 4 + 5 in)(7.2 in) = 12 in² +86.4 in²
Surface area = 98.4 in²
A nonhomogeneous equation and a particular solution are given. Find a general solution for the equation. y prime prime plus 9 y prime plus 18 y equals
Answer:
[tex]y_p(x) =c_1e^{-6x} + c_2e^{-3x}+ e^x + 4x^2[/tex]
Step-by-step explanation:
Given
[tex]y" + 9y' + 18y = 24x^2 + 40x + 8 + 12e^x[/tex] ---- (1)
[tex]y_p(x) = e^x + 4x^2[/tex]
Required
The general solution of [tex]y(x)[/tex]
Let
[tex]y = e^{nx}[/tex] be the trial solution of (1)
So:
[tex]y" + 9y' + 18y = 0[/tex] becomes
[tex]n^2 + 9n + 18 = 0[/tex]
Expand
[tex]n^2 + 6n+3n + 18 = 0[/tex]
Factorize
[tex]n(n + 6)+3(n + 6) = 0[/tex]
Factor out n + 6
[tex](n + 6)(n + 3) = 0[/tex]
Split
[tex]n +6 = 0\ or\ n + 3 = 0[/tex]
Solve for n
[tex]n =-6\ or\ n = -3[/tex]
So:
[tex]y = e^{nx}[/tex] becomes:
[tex]y = c_1e^{-6x} + c_2e^{-3x}[/tex]
[tex]y_p(x) = e^x + 4x^2[/tex] becomes
[tex]y_p(x) =c_1e^{-6x} + c_2e^{-3x}+ e^x + 4x^2[/tex]
Where: [tex]c_1[/tex] and [tex]c_2[/tex] are arbitary constants
WILL MARK BRAINLIEST! An orchestra of 120 players takes 40 minutes to play Beethoven's 9th Symphony. How long would it take for 60 players to play the symphony?
Let P be the number of players and T be the time playing.
Trick question! ;)
Answer:
Since in an orchestra each player plays parallely, i.e. everyone plays the same line simultaneously, hence the length of the play never depends on the number of players playing it. Hence, time taken by 60 players = time taken by 120 players = 40 minutes. So 60 person will play the 9th harmony in same 40 minutes.

Step-by-step explanation:
When Ximena commutes to work, the amount of time it takes her to arrive is normally distributed with a mean of 38 minutes and a standard deviation of 4.5 minutes. Using the empirical rule, determine the interval that represents the middle 68% of her commute times.
Answer:
The interval that represents the middle 68% of her commute times is between 33.5 and 42.5 minutes.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 38 minutes, standard deviation of 4.5 minutes.
Determine the interval that represents the middle 68% of her commute times.
Within 1 standard deviation of the mean. So
38 - 4.5 = 33.5 minutes
38 + 4.5 = 42.5 minutes.
The interval that represents the middle 68% of her commute times is between 33.5 and 42.5 minutes.

Additional comments
This is a product your scientific or graphing calculator can produce for you. Likely it will display the result in scientific notation because it won't have enough display digits to show you the product any other way. For smaller numbers, you can set the display mode to give you scientific notation.
If you choose to use a spreadsheet to perform this calculation, the numbers would be entered as 1.2e19 and 5.88e12. The result will be something like 7.056e31. You may have to format the display to show 3 decimal places.

NUMBER 3!
Answer:
Width = 17 feet, Length = 22 feet
Step-by-step explanation:
Let the width, w, be x
Therefore, length, L = x + 5
Perimeter = 78
p = 2(L+b)
78 = 2(x + x+5)
Adding the variables,
78 = 2( 2x + 5)
Dividing both sides by two,
39 = 2x + 5
Subtracting two from both sides,
34 = 2x
Dividing by two on both sides,
17 = x
Therefore, the width = x = 17 feet, and the length = x + 5 = 17 + 5 = 22 feet.
