The coordinates of A'', applying the two rotations, are given as follows:
A'' (4, 3).
What is a rotation?A rotation is one example of transformation that a function can undergo, in which the congruence and similarity of the images are kept but the orientation of the image changes.
The rules for each possible rotation are given as follows:
90° clockwise rotation: (x,y) -> (y,-x).90° counterclockwise rotation: (x,y) -> (-y,x).180° clockwise and counterclockwise rotation: (x, y) -> (-x,-y).270° clockwise rotation: (x,y) -> (-y,x).270° counterclockwise rotation: (x,y) -> (y,-x).The original coordinates are given as follows:
A(-3,4).
After the first 180º clockwise rotation, the coordinates are:
A'(3,-4).

For every 1/3 cups of flour, there are
7/8 cups of pumkin. How much flour (in
cups) should I use for 1 cup of
pumpkin?
Answer: 0.4176 cups of flour
Step-by-step explanation: First you'll need to convert both amounts to the same denominator, using their LCM, which is 24. 1/3 x 8 = 8/24, 7/8 x 3 = 21/24. Then calculate what you need to multiply 21/24 with to get 24/24, 21/24 = 0.875 1.000- 0.875 = 0.125. Finally, multiply 1/3 by 0.125 which is 0.416... / 0.4167, so you'll need 0.4167 cups of flour, or 4,167/10,000 of a cup os flour.
the graph of a lnear function passes through the point (-2, -7). When the input increses by 3 the value of the function increses by 8. what is the equation that models the function
The equation that models the function is y = 8/3(x) - 5/3.
Given:
The graph of a linear function passes through the point (-2, -7).
When the input increases by 3 the value of the function increases by 8.
(x,y) = (x+3,y+8)
(-2,-7) = (-2+3,-7+8)
= (1,1)
slope between (1,1) and (-2,-7) is m = -7-1/-2-1
= -8/-3
m = 8/3.
substitute m in y = mx + c
y = 8/3(x)+c
substitute (-2,-7)
-7 = 8/3(-2) + c
-7*3 = -16 + 3c
-21+16 = 3c
-5 = 3c
c = -5/3
y = 8/3(x) - 5/3.
Therefore the equation that models the function is y = 8/3(x) - 5/3.

Round your answer out to the two nearest decimal places

Answer:
-0.67
Step-by-step explanation:
What is the slope of the line created by this equation? Round your answer out to the two nearest decimal places. 6x + 9y = 1
_____________________________________________
Slope intercept form solves for y:
y = mx + b when m = slope and b = y-intercept
First, solve for y:
6x + 9y = 1
subtract 6x from both sides:
6x + 9y - 6x = 1 - 6x
9y = 1 - 6x
divide both sides by 9:
9y/9 = (1 - 6x)/9
y = 1/9 - 6/9x
reduce right side:
y = 1/9 - 2/3x
rearrange right side:
y = - 2/3x + 1/9
Back to the equation: y = mx + b when m = slope and b = y-intercept
your slope is -2/3

A rectangle that maximize the enclosed area has a length 800 yards and width is 800 yards. The maximum area is 640,000 square yards.
In the given question we have to find the maximum area of the rectangular area.
Liana has 3200 yards of fencing to enclose a rectangle.
So we know that the perimeter of rectangle is
P= 2(l+b)
Let length of the rectangle is x yards and width is y yards.
So the equation should be
2(x+y) = 3200
Divide by 2 on both side we get
x+y = 1600................(1)
As we know the area of rectangle is
A = xy
From the equation the value of y is 1600-x.
Now putting the value of y
A = x(1600-x)
A = 1600x-x^2
On differentiating
dA/dx = 1600-2x
Putting dA/dx=0
1600-2x=0
Subtract 1600 on both side we get
-2x= -1600
Divide by -2 on both side we get
x = 800 yards
Now putting the value of x in the y=1600-x
y=1600-800
y=800 yards
So the maximum area is
A= 800*800
A= 640,000 square yards
Hence, a rectangle that maximize the enclosed area has a length 800 yards and width is 800 yards. The maximum area is 640,000 square yards.

r is a relation on the set of all nonnegative integers. (a,b) is in r if a and b have the same remainder when divided by 5
The relation accepts reflexive, symmetry, and transitive.
Recall that a relation R is reflexive if the element (x, x) belongs to R for all elements X in the domain of R.
If (x, y) belongs to R, then follows that (y, x) must likewise belong to R, making the situation symmetric.
And it is transitive if (x, y) and (y, z) belongs to R necessarily implies that (x, z) belongs to R.
Given r is a relation on the set of all nonnegative integers R(a,b)
Reflexive - YES. A given number a will always have the same remainder when divided by 5.
Symmetric - YES. If a and b have the same remainder when divided by 5, then b and a are the same pair, so again they will have the same remainder.
Transitive - YES. If a and b as well as b and c have the same remainder when divided by 5, this is possible if both a and c also have the same remainder when divided by 5.
Therefore the relation accepts reflexive, symmetry, and transitive.

A sample of a radioactive isotope had an initial mass of 110 mg in the year 1990 and decays exponentially over time. A measurement in the year 1993 found that the sample's mass had decayed to 90 mg. What would be the expected mass of the sample in the year 2002, to the nearest whole number?
50 mg be the expected mass of the sample in the year 2002, to the nearest whole number
In 1990, a sample of a radioactive isotope had an initial mass of 110 mg and decayed exponentially over time.
A measurement in 1993 revealed that the sample's mass had decayed to 90
110 mg - 90 mg = 20 mg (amount decayed in the 3 total years)
20 mg ÷ 3 years = 6.6 mg decayed per year
6.6 × 9 years (years between 1993 and 2002) = 60 mg
110 mg - 60 mg = 50 mg, rounded to 50 mg

a researcher measures the amount of sugar in several cans of the same soda. the mean is 39.01 with a standard deviation of 0.5. the researcher randomly selects a sample of 100. find the probability that the sum of the 100 values is greater than 3,908. (round your answer to four decimal places.)
Using the concepts of probability, we got that 0.0764 is the probability that the sum of the 100 values is greater than 3,908 when a researcher measure the amount of sugar in several cans of the same soda.
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
Z=(X-μ)/σ
The z-score measures how many standard deviations the measure is above or below the mean.Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation .For this problem, these parameters are given as follows:
μ=39.01,σ=0.5,n=100,s=0.5/√100=0.05
A sum of 3908 is equivalent to a sample mean of 3908/100 = 39.08, which means that the probability is the p-value of Z when X = 39.08, hence:
Z=(X-μ)/σ
By the Central Limit Theorem:
Z=(X-μ)/s
=>Z=(39.08-39.01)/0.05
=>Z=(0.07)/0.05
=>Z=7/5
=>Z=1.4
Z = 1.4 has a p-value of 0.0764.
Hence, the probability that the sum of the 100 values is greater than 3,908 is 0.0764.

What is an oblique cylinder?
When a cylinder "leans over," that is when its sides are not parallel to its bases, then the cylinder is said to be an oblique cylinder. The bases (ends) of an oblique cylinder stay parallel to one another, while the sides tilt outward at an angle that isn't quite 90°.
An oblique cylinder will have the same volume as a right cylinder with the same radius and height. As long as the radius and height are the same, the volume does not vary, but the height must equal the perpendicular height.

Earlier the length is 238cm and the breadth is 435cm.
Now replace the breath 435cm to 27cm.
length = 238cm
breadth = 27cm
Therefore we get the perimeter of the rectangle:

2x+5=47
Subtract 5 too
2x=42
Then divide by 2
x=21
We can check our answer by adding all the angles
71+62+(2*21+5)
71+62+(42+5)
71+62+47=180
