Answer:

a) Josef jogging from A to B;

i. speed = 2 m/s

ii. velocity = 2m/s

a) a) Josef jogging from A to C;

speed = 1.9 m/s

ii. velocity = 2.2 m/s

Step-by-step explanation:

One major difference between speed and velocity is that speed is a scalar quantity, while velocity is a vector quantity.

a) Josef jogging from A to B;

distance = 300 m

time = 2.5 seconds = 150 seconds

i. his average speed = [tex]\frac{distance}{time}[/tex]

                               = [tex]\frac{300}{150}[/tex]

                               = 2 m/s

ii. his average velocity = [tex]\frac{displacement}{time}[/tex]

                               = [tex]\frac{300}{150}[/tex]

                               = 2 m/s

b) Josef jogging from A to C,

distance = 300 + 100 = 400 m

time = 2.5 + 1 = 3.5 minutes

        = 210 seconds

i. his average speed = [tex]\frac{distance}{time}[/tex]

                                  = [tex]\frac{400}{210}[/tex]

                                  = 1.9 m/s

ii. his average velocity = [tex]\frac{\sqrt{V_{1} ^{2} + V_{2} ^{2} } }{2}[/tex]

[tex]V_{1} ^{2}[/tex] = 4 m/s

[tex]V_{2} ^{2}[/tex] = 1.9 m/s

his average velocity = [tex]\frac{\sqrt{4^{2} + 1.9^{2} } }{2}[/tex]

                                  = 2.2 m/s

Answer:

  (b) Line SW has an undefined slope.

  (c) Line TV has a slope of 0.

  (d) Lines RS and TV are parallel.

Step-by-step explanation:

A horizontal line has 0 slope. Lines RS and TV are horizontal, hence are parallel and have 0 slope.

A vertical line has undefined slope. Line SW is vertical, hence has undefined slope.

Answer:

[tex]\approx 68\%[/tex]

Step-by-step explanation:

For normal distributions only, all data falls within approximately 68% of one standard deviation, 95% of two standard deviations, and close to 100% of three standard deviations. The standard deviation is far too small to represent two or three standard deviations, hence [tex]\implies \boxed{68\%}[/tex].

*Important: This problem would be unsolvable if the question did not say her cuts were normally distributed, because the information above is only applicable to normal distributions.

Step-by-step explanation:

Given polynomial :-

=> 2x - 4x³ -7 + 6x²

Here the highest degree of variable is 3 ,

Therefore it is a cubic polynomial .

Answer:

In slope-intercept form:

[tex]\displaystyle y=\frac{2}{3}x+1[/tex]

Or, in standard form:

[tex]2x-3y=-3[/tex]

Step-by-step explanation:

We want to find the equation of the line that passes through the point (6, 5) and is perpendicular to the line whose equation is:

[tex]2y+3x=6[/tex]

Since the new line is perpendicular, its slope and the slope of the first equation will be negative reciprocals of each other.

So, find the slope of the first equation. Subtract 3x from both sides:

[tex]2y=-3x+6[/tex]

And divide both sides by two:

[tex]\displaystyle y=-\frac{3}{2}x+3[/tex]

So, the slope of the first equation is -3/2.

The slope of the new line is its negative reciprocal. So, the slope of the perpendicular line is 2/3.

Next, we also know that it passes through the piont (6, 5). We can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

Substitute:

[tex]\displaystyle y-(5)=\frac{2}{3}\left(x-6\right)[/tex]

And we have our equation!

If desired, we can simplify it into slope-intercept form:

[tex]\displaystyle \begin{aligned} y-5&=\frac{2}{3}x-4\\\\y&=\frac{2}{3}x+1\end{aligned}[/tex]

Or, into standard form:

[tex]\displaystyle \begin{aligned} y&=\frac{2}{3}x+1\\\\3y&=2x+3\\\\ 2x-3y&=-3\end{aligned}[/tex]

Step-by-step explanation:

Answer:

-15

Step-by-step explanation:

Step 1: Multiply 3 by both sides

3(2/3x)=3(-10)

Step 2: Simplify

2x=-30

Step 3: Divide both sides by 2

2x/2=-30/2

Step 4: Simplify

x=-15

Answer:

C; 500%

Step-by-step explanation:

To get the percentage, we need to make a straight division, then multiply by 100%

We have this as;

(4.5 * 10^5)/(9 * 10^4) * 100%

= 5 * 100% = 500%

Answer:

You will save $20.

Step-by-step explanation:

IMPORTANT FORMULA: TO CONVERT A NUMBER TO A PERCENT, YOU HAVE TO MULTIPLY BY 100. TO CONVERT A PERCENT TO A NUMBER, YOU HAVE TO DIVIDE BY 100.

1) Some percent of an amount is what?  

Using the formula above, I can conclude that 40% is equal to 40/100=4/10=2/5

2) Translate into an equation.

It is important to keep in mind that we are trying to find 40% of $50 in order to find out how much money will be saved.

In the above step, we already found that 40% = 2/5.

I also know that, in mathematics, the word "of" means multiplication.

Therefore, I am trying to find 40% of $50 is the same as 2/5 * $50.

2/5 * $50 = x    ------ (x represents the money saved)

3) Solve for variable.

$20 = x

4) Write a sentence to answer the question.

You will save $20.

Answer:

The common difference is definitely 3. The common difference is the difference between the numbers in a sequence. In the sequence 3,6,9,12, and 15 the common difference is 3.

Answer:

The ratios are 15 18 and 17 which total 50

So one person will receive 15/50 = 30 per cent

Another person receives 18/50 = 36 per cent

The third person receives 17/50 = 34 per cent

1st Person  30% of 3,990 = 1,197.00

2nd Person  36% of 3,990 = 1,436.40

3rd Person   34% of 3,990 = 1,356.60

Step-by-step explanation:

Answer:

$1197 : $1436.4 : $1356.6

Step-by-step explanation:

15 + 18 + 17 = 50

3990 / 50 = 79.8

1st person : 79.8 x 15 = 1197

2nd person : 79.8 x 18 = 1436.4

3rd person : 79.8 x 17 = 1356.6

$1197 : $1436.4 : $1356.6

Answer:

Break-even point is at quantity 220.

Step-by-step explanation:

Given the rent amount that is fixed cost for the store = $550

The average cost of the goods = $3

The average price of the goods = $5.50

Let the total number of break-even items = Q

Thus, total revenue = 5.50 x Q = 5.50Q

At break-even, TR = TC

5.50Q = FC + VC

5.50Q = 550 + 3Q

5.50Q - 3Q = 550

2.50Q = 550

Q = 550 / 2.50

Q = 220

Thus break-even point is at quantity 220.
