Answer:

d⁴y/dx⁴ = -12/x⁴

Step-by-step explanation:

y = 2In x

We want to find d⁴y/dx⁴. This is the fourth derivative.

Using product rule, first derivative is;

dy/dx = 2/x

Answer:

B

Step-by-step explanation:

You know that the graph intercepts at the point of (4,-2)

Where x = 4 and y = -2.

This means that whenever you plug a value of x in the equation it should give the value of y.

For example when you plug x= 4 into the equation (B), it should look like this.

4- y = 6, solving for y gives us the value negative 2.

This means that it does give us this point, however, as the graph shows us, both lines meet at the point which means that both equation should give us this point.

If we substitute x = 4 in the second equation of b, we should be able to get 3(4) + 4y = 4. Solving for y gives us -2.

Hope this helps!

From the values in the statistical data we have;

The possible given data in question, are as follows;

[tex]\begin{array}{cccc}1\frac{3}{4} &2\frac{1}{2} &2&2\frac{3}{4} \\\\1&1\frac{3}{4} &1\frac{1}{4} &3\\\\3\frac{1}{4} &3\frac{3}{4} &2&2\end{array}\right][/tex]

From the data, we have;

The most amount of time spent = [tex]3\frac{3}{4}[/tex]

The least amount of time spent = 1

Therefore;

The most amount of time is [tex]3\frac{3}{4} \times 1[/tex] = [tex]3\frac{3}{4}[/tex] times the least amount of time

Second part;

The number of students that spent less than [tex]2\frac{1}{2}[/tex] = 7

The number of students that spent [tex]2\frac{1}{2}[/tex] or more = 5

The number of students in the survey = 12

Therefore, more than half the students spent less than [tex]\mathbf{2\frac{1}{2}}[/tex] hours on homework

Answer:

-1/5

Slope is given by the change in y over the change in x.

Change in y: 2-1= 1

Change in x: 5-10= -5

Answer:

-5

Step-by-step explanation:

In order to find the slope of two points you need to remember a few things.

(x,_)

The first number in an ordered pair is the x value. That determines the position of a point on the x axis. (Left or right)

(_,y)

The second number in an ordered pair is the y value. That determines the position of a point on the y axis. (Up or down)

(x,y)

Calculating slope

Take the y value from one of your ordered pairs and subtract that value from the other y value.

(10,1) and (5,2)

We will take the numbers 1 and 2.

1-2=-1

Take the x value from the y value you subtracted. Since we used 1 as our first y value we will take its x value 10

(If we started with 2 we would take its x counterpart, which is 5)

10-5=5

Divide -1 by 5 and you get -1/5

(y2-y1) divided by (x2 - x1)

Step-by-step explanation:

The field is circular and the line drawn by chalk is length of the rim of the circular field, and is called circumference. It can be calculated from radius(or diameter) of the circle.

The length of the chalk outline is given by:

Option A: 19 feet.

The length of the chalk outline.

[tex]|Circumference| = 2 \times \pi \times r = \pi \times d[/tex]

where r represents the radius of the circle and d represents the diameter of the circle.

The diameter d = 2 times r always. (diameter is twice of length of radius)

Thus, we have:

[tex]\text{Length of chalk line} = \pi \times d = \pi \times 6 \approx 18.84 \approx 19 \rm \: feet[/tex]

The length of the chalk outline is given by:

Option A: 19 feet.

Step-by-step explanation:

PS AND PQ IS THE SAME,

which means that each side is the same,(left and right)

a triangle, has 180 degrees

180-90

=90

90/2(get the angle of each sides that are left)

=45 degrees is the answer

Now pay up 100 points, lol

Answer:

The measure of angle a is 45 degrees.

Step-by-step explanation:

Notice that since PS = RS, this is an isosceles triangle. This means that the base angles are equal. We also know that the sum of interior triangles of a triangle equals 180, then, if 'a' is the base angle, we have the following equation:

90 + a + a = 180

2a = 180 - 90 = 90

a = 90/2 = 45

a = 45

The length of the diameter is 16 cm.

The area of a circle is pi times the radius squared.

i.e., Area of Circle = πr².

Given:

Area = 64π m²

Now, Area of Circle= πr²

64π = πr²

64 = r²

r= √64

r= 8 cm

Answer:

50 dog walks in 10 hours (1 month)

Step-by-step explanation:

If Darius made 10 dog walks in 2 hours,   then in one month, it took Darius  10 hours to make 50 dog walks.

Using the first formula,    2 hours ÷ 1/5 = 10, then

                                        10 hours (in one month)  ÷  1/5 = 50 dog walks.

Hope this helps!

In problem #1,  rewrite the problem using the reciprocal (the inverse) of 1/5 to 5/1  and change the division sign to multiplication.  Do this for both equations.

Problem 1.)   Write 2 ÷ 1/5  =  2 x 5/1 = 10.

Problem 2.)   10  ÷ 1/5 = 10 x 5/1 =50.

Problem 3.)  Just explain that in one month, it took Darius 10 hours to walk 50 dog walks using the formula from problem 2 above. Good Luck!
