Answer:

Step-by-step explanation:

The answer is where the graph cuts the x-axis.

I can't see it very well but it looks like x = -0.4 and 2.3.

Replace each x value and see if it matches its output (y value) , for each function.

A.

y= 4+ 3x

x=1 ,y=7

(7)=4 + 3(1)

7= 4 + 3

7=7

x=2, y=11

11= 4 +3(2)

11= 4+6

11= 10 NOT EQUAL

B.

y= 3 + 4x

x=1,y=7

(7)= 3 +4 (1)

7= 3+4

7=7

x=2, y=11

11= 3 + 4(2)

11=3 +8

11=11

x=3, y=15

15= 3 + 4(3)

15=3 + 12

15=15

x=4, y=19

19= 3 + 4(4)

19=3+16

19=19

x=5 , y=23

23 = 3 + 4(5)

23= 3 + 20

23=23

Correct option = y=3+4x

The integral to be evaluated is;\(∫∫_R▒〖8(x-7y)/(6x-y)dA〗\) R where R is the parallelogram enclosed by the lines \(x-7y=0, x-7y=5, 6x-y=7 and 6x-y=9\). The solution is 264/41 and it is obtained by using an appropriate change of variables.

This integral can be solved by making an appropriate change of variables which will simplify the integral.The lines \(x - 7y = 0 and 6x - y = 7\) intersect at (7,1)

while\(x - 7y = 5 and 6x - y = 9\) intersect at (9,1). This implies that the length of the parallel sides of the parallelogram is 2 units while the distance between the parallel lines is 5 units.

Therefore, we can define the transformation function as:\(u = 6x - y, v = x - 7y\).The Jacobian is given as:\(∂(u,v)/∂(x,y) = (6)(-7) - (1)(-1) = -41\)

The integral can now be expressed as:\(∫∫_R▒〖8(x-7y)/(6x-y)dA〗 = ∫_1^7▒〖∫_(5+y/7)^((y+9)/6)▒〖8(u/(-41))dudv〗〗 = ∫_1^7▒〖(1/41)∫_(5+y/7)^((y+9)/6)▒8udu dv〗\)  

= \(∫_1^7▒〖[(1/41)(4(u^2)/2)|_((5+y/7)^((y+9)/6))]dv〗 = (1/41)∫_1^7▒[16(5+y/7)^2/2 - 16((y+9)/6)^2/2]dv = (1/41)[(160(5+y/7)^2/2 - 16((y+9)/6)^2/2)|_1^7] = 264/41.\)

The stopping distance of D40 is 2.56 times the stopping distance of D25.

Given that are two initial velocities: 40 mph and 25 mph, with which the car's stopping distance is D40 and D25.

The final velocity for both is 0 mph (as the car to a stops).

We need to compare the stopping distance D40 to the stopping distance D25.

Use the third equation of motion for both cases to get the comparison.

The equation is given by:

\(v^2 - u^2 = 2as.\)

Case 1)

\(0 - 40^2 = 2a(D40)\)

Case 2)

\(0 - 25^2 = 2a(D25)\)

Comparing the obtained expressions.

\(\frac{40^2}{25^2} = \frac{2a(D40)}{2a(D25)}\)

\(2.56 = \frac{D40}{D25}\)

\(2.565 \times D25 = D40\)

Hence the stopping distance of D40 is 2.56 times the stopping distance of D25.

The required standard deviation of the new data set is 9.

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

When 16 is added to each number in the data set, the variance of the new data set is not affected. The variance of a data set is the average of the squared deviations of the data values from the mean, and adding a constant to each data value shifts the mean but does not affect the deviations or their squares.

However, the standard deviation, which is the square root of the variance, will change because the standard deviation is expressed in the same units as the original data, while the variance is expressed in squared units. To find the standard deviation of the new data set, we need to take the square root of the variance, which is 81, and add 16 to each data value. The standard deviation of the new data set is equal to the square root of 81 + 16 = 9.

So, the standard deviation of the new data set is 9.

Question for the answer questions about the question question for you and I have to do a little more

The area of the parallelogram is four hundred twenty-one and seven-eighths ft². Option B is the correct option.

What is parallelogram?

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles are supplementary to the transversal on the same side. 360 degrees is the sum of all interior angles.

Given that the base of the parallelogram is 22 and one-half feet and the height is 18 and three-fourth feet.

22 and one-half and 18 and three-fourths both are mixed fractions.

Convert 22 and one-half and 18 and three-fourths into improper fractions:

\(22\frac{1}{2}\) = 45/2

\(18\frac{3}{4}\) = 75/4

The area of a parallelogram is the product of base and height.

The area of the parallelogram is

45/2 × 75/4

= 3375/8

= 421 + (7/8)

= \(421\frac{7}{8}\)

= four hundred twenty-one and seven-eighths ft²

Answer:

100 minutes

Step-by-step explanation:

This is because it takes 5 minutes to fry 24 wantons, so we can write 5/24. Now we need to find out how long it takes to fry 40 dozen wantons, or 480 wantons. We can rewrite this as x/480. Since the time should be proportional, we get the following:

5/24 = x/480

We can now cross multiply. 24x=5x480. Therefore, 24x = 2400. If we divided each side by 24, we would get 100. Therefore, it takes 100 minutes to fry 40 dozen wantons, or about 1  2/3 hours.

Answer:

100 minutes (1 hour & 40 minutes).

Step-by-step explanation:

5 minutes = 2 dozen, which means it takes 2.5 minutes to cook 1 dozen.

After reducing all the book prices by 50%, the new median price is determined to be $7.70 (B)

To find the new median price after reducing all the book prices by 50%, we first need to calculate the reduced prices. By reducing each given price by 50%, we get $6.375, $7.40, $9.995, $4.975, $8.00, and $8.975 respectively.

Next, we arrange these reduced prices in ascending order: $4.975, $6.375, $7.40, $8.00, $8.975, and $9.995. The median is the middle value in this ordered list. Since there are six prices, the middle two values are $7.40 and $8.00.

To find the median, we take the average of these two values, which gives us ($7.40 + $8.00) / 2 = $7.70.

Therefore, the new median price, after reducing all the book prices by 50%, is $7.70 (B). This means that the median price of the books, after the reduction, is $7.70.

none of the provided options (a, b, c, d) appear to be accurate or close to the minimum space required.

To determine the minimum space required for a male restroom design with the given plumbing requirements, we need to consider the minimum space required for water closets and lavatories.

The minimum space required for water closets is typically around 30-36 inches per unit, and for lavatories, it is around 24-30 inches per unit.

Since the design requires a minimum of 12 water closets and 13 lavatories, we can estimate the minimum space required as follows:

Minimum space required for water closets = 12 water closets * 30 inches = 360 inches

Minimum space required for lavatories = 13 lavatories * 24 inches = 312 inches

Adding these two values together, we get a total minimum space requirement of 672 inches.

Now, the adjacent and congruent angle to AOE is angle EOC, because they are on a straight angle, they are supplementary angles and also adjacent angles.

Answer:

Step-by-step explanation:

We can already tell that these two figures are congruent due to the angles (if you remember, the "top" and "bottom" angles of trapezoids form 180 degrees). Since we know that these are congruent, we know that GH = BC, and so on. We can then plug in the missing sides by looking at the figure that has the sides. Thus, giving us 157.

Using the Riemann sum, we divide the interval [2, 4] into n equal subintervals, where Δx = (4 - 2) / n.

To find the expression for the area under the graph of the function f(x) = x^2 √(1/2x) as a limit, we can use the definition of a Riemann sum and take the limit as n approaches infinity of the sum from i = 1 to n.

The Riemann sum is a method to approximate the area under a curve by dividing it into smaller rectangular regions. In this case, we need to express the area under the graph of f(x) as a limit of a Riemann sum.

The expression for the area under the graph of f(x) as a limit is given by:

lim n → ∞ Σ i=1^n [f(xi) Δx]

In this formula, xi represents the ith subinterval, Δx represents the width of each subinterval, and f(xi) represents the value of the function at a point within the ith subinterval.

To calculate the Riemann sum, we divide the interval [2, 4] into n equal subintervals, where Δx = (4 - 2) / n. Then, for each subinterval, we evaluate f(xi) and multiply it by Δx. Finally, we sum up all these values as n approaches infinity.

However, without evaluating the limit or specifying the specific method of partitioning the interval, it is not possible to provide a more precise expression for the area. The given information is insufficient to calculate the exact value.
