Is speed the rate of change in the velocity of a moving body?

Answers

Answer 1

No, speed is the rate of change of distance.

Velocity is the rate of change of displacement.

Distance is scalar quantity, it has just magnitude.

Displacement is vector quantity, it has both magnitude as well as direction. So, speed and velocity are scalar and vector respectively too.

The cost is 23$ when___coolers are produced

Answers

9514 1404 393

Answer:

  97

Step-by-step explanation:

We want to find x when C = 23.

  23 = 0.005x^2 -0.35x +10

  2600 = x^2 -70x . . . . . . subtract 10, multiply by 200

  2600 +35^2 = (x -35)^2 . . . . complete the square

  61.847 +35 = x . . . . . . . square root, add 35 (use the positive result only)

  x ≈ 97 . . . . rounded to integer

The cost is $23 when 97 coolers are produced.

what is the formula for lineal equetion​

Answers

Answer:

y=mx+c

Step-by-step explanation:

A linear equation means the equation of straight line.

The formula for equation of straight line in slope intercept form is y=mx+c

where, m is the slope of line and c is the y intercept

The formula for equation of straight line in double intercept form is x/a+y/b=1

The formula for equation of straight line in normal form is xcos α + y cos α=p

There are more formulas bur assuming you are asking for the general representation of the straight-line equation, it is y=mx+c.

What will be the value of median of a moderately asymmetrical distribution? If the mean and mode are 30 and 24 respectively.

Answers

The mean, the median and the mode are measures of central tendency, and they are related in some many ways, depending on the type of distribution.

The median of the moderately asymmetrical distribution is 26

The given parameters are:

[tex]Mean = 30[/tex]

[tex]Mode = 24[/tex]

For a moderately asymmetrical distribution, the mean, median and mode are related by the following equation:

[tex]Mode = 3 * Median - 2 * Mean[/tex]

Substitute known values

[tex]30= 3 * Median - 2 * 24[/tex]

[tex]30= 3 * Median - 48[/tex]

Collect like terms

[tex]3 * Median =30+ 48[/tex]

[tex]3 * Median =78[/tex]

Divide both sides by 3

[tex]Median =26[/tex]

Which word describes the relationship of the points (3, 1)
and (3, 6)?
OA) collinear
OB) parallel
C) perpendicular
OD) coincident

Answers

9514 1404 393

Answer:

  A)  collinear

Step-by-step explanation:

"Parallel" and "perpendicular" are descriptors of pairs of lines and planes. They do not apply to pairs of points.

The two points have different coordinates, so are distinct, rather than coincident.

Of these words, the only applicable choice is "collinear."

__

Additional comment

Any pair of distinct points is collinear. Two points define a line, and two points on the same line are collinear.

At the movie theatre, child admission is $5.80 and adult admission is $9.70. On Wednesday, 171 tickets were sold for a total sales of $1296.00. How many
child tickets were sold that day?

Answers

Answer:

93 child tickets

Step-by-step explanation:

Create a system of equations where c is the number of child tickets sold and a is the number of adult tickets sold:

c + a = 171

5.80c + 9.70a = 1296.00

Solve by elimination by multiplying the top equation by -9.7:

-9.7c - 9.7a = -1658.7

5.8c + 9.7a = 1296

Add these together and solve for c:

-3.9c = -362.7

c = 93

So, 93 child tickets were sold.

Find x and y from the triangle.

Answers

Answer:

x = 39

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + x + 12 + 90 = 180

2x + 102 = 180 ( subtract 102 from both sides )

2x = 78 ( divide both sides by 2 )

x = 39

Then

x = 39°

x + 12 = 39 + 12 = 51°
