Answer:

yes

Step-by-step explanation:

A car's appreciation depends on the it's rarity and and popularity. Unfortunately, it usually takes time for a car to appreciate, at least 20 years, when people become nostalgic and are willing to pay more for a car which is usually considered a classic by that time.

Answer:

The 2nd motion eqn.

S = ut + 1/2gt²

where, u is the initial speed of the elevator

S = position

and t = x

y = ux + 1/2gx²

y = 1/2gx² + ux

since the elevator started at 0 as initial speed(that is at rest)

y = 1/2gx² + 0

y = 1/2gx² is the eqn

Answer:

We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $25. Option B is a commission rate of 8% on weekly sales.

First of all we will find amount earned by salesperson with option A.

The salespersons earns $1000 through option A.

Let x be the amount of weekly sales.  

8% of x should be equal to 1000 for salesman to earn the same amount with the two options.

Therefore, the salesman needs to make a weekly sales of $12,500 to earn the same amount with two options.We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid.

Step-by-step explanation:

Hi there!

Given;

base (b) = 6.5 inches

height (h) = 8 inches

Now;

[tex]area= \frac{1}{2}*b*h[/tex]

[tex]area (a)=\frac{1}{2}*6.5*8[/tex]

area = 52/2

Therefore, the area of the triangle is 26 [tex]inches^{2}[/tex].

slope = undefined

Step-by-step explanation:

1. The formula to find a slope of a line given two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

2. Since anything divided by 0 = undefined, the slope is undefined.

Answer:

(6x+3)=120

6x=120-3

6x=117

x=117/6

x=19.5

(7x-19)=120

7x=120+19

7x=139

x=139/7

x=19.85

Answer:

D. -15/4

Step-by-step explanation:

Using PEMDAS, I know that I have to begin by calculating the expression inside the parentheses: -25 divided by 1/3. Dividing by 1/3 is the same as multiplying by 3. -25 multiplied by 3 is equal to -75. Then, working from right to left, we multiply that by 1/5. 1/5 of -75 is -15. Now, we take that -15 and multiply it by 1/4. This is equivalent to -15/4.

Answer:

When rotating a point 90 degrees counterclockwise about the origin the point (7,4) becomes (-4,7).

Step-by-step explanation:

In other words, just switch x and y and make y negative.

The point will be inverted when (7,4) is rotated 90° counterclockwise i.e., the new point will be (4,7).

It is given that a point (7,4) is rotated 90° counterclockwise about origin.

We have to find the new point after rotation.

What do you mean by rotation counterclockwise ?

If something is moving counterclockwise that meant it is moving in the opposite direction to the direction in which the hands of a clock move.

As per the question ;

A point (7,4) is rotated of 90° counterclockwise about origin.

Let's assume (7,4) = (x , y)

If we rotate it 90°counterclockwise ; then the point will be inverted ; i.e.,

(x , y ) ⇒ ( y , x)

So ;

( 7 , 4 ) = ( 4 , 7 )

So ;

The new point will be ;

= ( 4 , 7 )

Thus , the point will be inverted when (7,4) is rotated 90° counterclockwise i.e., the new point will be (4,7).
