8=-2/5c what does c=

Answer:

392 N/m

Step-by-step explanation:

We know that the total mechancial enery will be conserved from when the apple drops to when it hit the spring.  Therefore, we can set the potential energy of the apple equal to the elastic potential energy of the spring.

PE = mgh and SE = 1/2kx² — PE is the initial potential energy of the apple and SE is the elastic potential energy of the spring.

mgh = 1/2kx².  (.1)(9.8)(2) = (1/2)(k)(.1²), solve for k. k = 392

Step-by-step explanation:

-5 how high/ low you go on y axis

3 how far you move left on the graph

The two ways that could use a slope of -5/3 to graph a line are;

-5 high/ low and go on the y-axis and 3 when moving left on the graph

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

The more the slope of the line, the more the line is vertical. When the slope is zero, then the line is horizontal.

To determine the slope, we take the ratio of how much the line's height increases as we go forward or backward on the horizontal axis.

If two lines are given as perpendicular to each other, then their slopes are negative reciprocals of each other. which means, if one line's slope is 'a', then its perpendicular line's slope would be -1/a

A Slope of a straight object is the ratio of how much amount of rise occurs in correspondence to the increment in the run.

Step-by-step explanation:

Answer:

Surface area: 1216

Volume: 4608

Step-by-step explanation:

Scale factor: 5:8

This means that the dimensions of the larger figure are 8/5 of those in the smaller figure.

Surface area:

The surface area is found multiplying the square of the change(8/5) by the original surface area(475). So

[tex]S = (\frac{8}{5})^2 \times 475 = \frac{64}{25} \times 475 = 64 \times 19 = 1216[/tex]

Volume:

The volume is found multiplying the cube of the change(8/5) by the original volume(1125). So

[tex]S = (\frac{8}{5})^3 \times 1125 = \frac{512}{125} \times 1125 = 512 \times 9 = 4608[/tex]

Step-by-step explanation:

We list the numbers from least to greatest

19, 23, 30, 33, 34, 40, 49, 50, 59, 67

The current median is 37

if you add 58, it would be

19, 23, 30, 33, 34, 40, 49, 50, 58, 59, 67

so the median changes to 40

Answer:

Approximately 20525 seconds

Step-by-step explanation:

Distance between San Francisco and Los Angeles is not given.

Therefore, by using I-5 S, distance between these cities = 381.6

                                                                                             ≈ 382 miles

Formula for the average speed is,

Average speed = [tex]\frac{\text{Distance traveled}}{\text{Time taken}}[/tex]

Time taken to reach San Francisco from Los Angeles = [tex]\frac{\text{Distance traveled}}{\text{Average speed}}[/tex]

                                                                                       = [tex]\frac{382}{67}[/tex]

                                                                                       = 5.702 hours

                                                                                       ≈ 5 hours 42 minutes

                                                                                       ≈ 342.1 minutes

                                                                                       ≈ 20525 seconds

Answer:

positive ! the answer would be 97

Step-by-step explanation:

since you are subtracting a negative ( - - ) that automatically makes the answer positive. anytime you see subtraction sign next to a negative sign, you add !! (94 + 3 = 97! )

Answer:

g = -15

Step-by-step explanation:

First, you are going to want to divide by -11 on both sides of the equation.

— (4 + g) (-11) / -11 = 121 / -11

— 4 + g = -11

(Note: dividing a positive number by a negative number will result in a negative number.)

Next, subtract 4 from both sides of the equation.

— 4 + g - 4 = -11 - 4

— g = -15

So, assuming you are looking for the value of g, you're answer is g = -15

4 numerical variables (Sepal Length ; Sepal Width ; Petal Length ; Petal Width)

All four numerical variables are continous.

Step-by-step explanation:

Number of cases = Number of species * number of flowers per species

Number of cases = 3 * 57 = 171 cases

B.) Numerical variables are those variables which are quantitative in nature, that is they are made of numbers which are capable of being used for mathematical computation in a dataset such as maximum, minimum, mean and slither statistical measures.

C.) All for variables are continous as they are capable of taking up unlimited number of values within its range, including decimal values. Hence they are not finite. Continous numberical variables include, length, height, width and as given in the scenario below, they are all continous.

corresponding angles: 7 and 3

alternate exterior angles: 12 and 5

alternate interior angles: 2 and 11

vertical angles: 7 and 6

Step-by-step explanation:

corresponding angles: 7 and 3

alternate exterior angles: 12 and 5

alternate interior angles: 2 and 11

vertical angles: 7 and 6

corresponding angles: 7 and 3 = In this, the pairs of angles should be found in a similar position on various intersections.

alternate exterior angles: 12 and 5 = This should be said when two angles lie on the inverse sides of the transversal and should be placed on two distinct lines.

alternate interior angles: 2 and 11 = In this, angles are created at the time when a transversal intersects two coplanar lines.

Answer:

The solution to the system of equations

Hence, the value of q = -50

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}-16p-2q=100\\ p-4q=200\end{bmatrix}[/tex]

solving to determine the value of q

Multiply p − 4q = 200 by 16:      [tex]16p-64q=3200[/tex]

[tex]\begin{bmatrix}-16p-2q=100\\ 16p-64q=3200\end{bmatrix}[/tex]

so adding the equations

[tex]16p-64q=3200[/tex]

[tex]+[/tex]

[tex]\underline{-16p-2q=100}[/tex]

[tex]-66q=3300[/tex]

so

[tex]\begin{bmatrix}-16p-2q=100\\ -66q=3300\end{bmatrix}[/tex]

solve -66q = 3300

[tex]-66q=3300[/tex]

Divide both sides by -66

[tex]\frac{-66q}{-66}=\frac{3300}{-66}[/tex]

[tex]q=-50[/tex]

substituting q = -50 in −16p − 2q = 100

[tex]-16p-2\left(-50\right)=100[/tex]

[tex]-16p+100=100[/tex]

Subtract 100 from both sides

[tex]-16p+100-100=100-100[/tex]

Simplify

[tex]-16p=0[/tex]

Divide both sides by -16

[tex]\frac{-16p}{-16}=\frac{0}{-16}[/tex]

[tex]p=0[/tex]

Thus, the solution to the system of equations

Hence, the value of q = -50
