A roller coaster accelerated from rest to 55 m/s by the time it reached the first hill. The roller coaster took 15 seconds to climb to the top of the hill. What was the acceleration of the coaster?

Answers

Answer 1

Answer:

I believe the acceleration is 3.66666666667 m/s

Step-by-step explanation:

Acceleration formula: a = vf - vi / t

Initial velocity: 0 (I believe it was 0, as it wasn't moving in the beginning)

Final velocity: 55 m/s

Time: 15 s

Substituting values: 3.66666666667 = 55 - 0 / 15

SOMEONE PLS HELP

Answers

Answer:

C. neither parallel nor perpendicular

Step-by-step explanation:

Given lines:

y + 5/3x = -4 and 3y - 5x = 9

To determine the relationship between the lines put them both into slope-intercept form and compare the slopes.

y + 5/3x = -4  ⇒ y = -5/3x - 43y - 5x = 9     ⇒ 3y = 5x + 9      ⇒ y = 5/3x + 3

The slopes are different so the lines are neither parallel nor perpendicular.

Correct choice is C

Answer:

Neither parallel nor perpendicular

Step-by-step explanation:

If two lines are parallel, they share the same slope. If two lines have slopes that are opposite reciprocals of each other, then they are perpendicular. If it is the same line, then the two equations must be the same when converted into the same form. If none of these apply, then the line is neither of any these.

1) First, convert each equation into y = mx + b format, or slope-intercept form, to easily identify their slopes. Isolate y in both equations.

First equation:  

[tex]y + \frac{5}{3} x = -4\\y = -\frac{5}{3} x-4[/tex]

Second equation:

[tex]3y - 5x = 9 \\3y = 5x + 9 \\y = \frac{5}{3} x + 3[/tex]

2) In slope-intercept format, the coefficient of the x term, or m, represents the slope. Thus, the slope of the first equation is [tex]-\frac{5}{3}[/tex] while the slope of the second equation is [tex]\frac{5}{3}[/tex]. The slopes are not the same, nor are they opposite reciprocals of each other. The equations are not the same either. Therefore, they are neither parallel nor perpendicular.

Helping me would be very appreciated.

A baby weighs 18 pounds at her four-month appointment. Six months later she weighs 24 pounds. By what percentage did the baby's weight increase?​

Answers

Answer:

33.33%

Step-by-step explanation:

We know that:

At her four month weighs: 18 pounds.

Six month later weighs: 24 pounds.

So, the baby increased 6 pounds. But, what percentage represents?

To solve this problem we use the rule of three:

If 18 pounds represents 100%, 24 pounds what percentage would be?

So, if we subtract 100%-133.33%, we have a 33.33% more. This means that the baby increased a 33.33% during those six months.

Brianna bought snacks for her team's practice. She bought a bag of oranges for $2.63 and an 8-pack of juice bottles. The total cost before tax was $16.07. Write and solve an equation that can be used to determine xx, how much each bottle of juice costs?

Answers

Answer:

$1.68

Step-by-step explanation:

The total cost is $16.07 and there was 2 things bought- the oranges and the juice bottles. to make it easier to find the cost of the juice bottles, we'll subtract the cost of the oranges (2.63) from the total (16.07), which gives us 13.44. this number represents the total cost of only the bottles. To find out the cost if each individual bottle, you need to divide the total (13.44) by the number of bottles (8). This gives us 1.68, so the cost of each bottel is $1.68

Answer: 1.68

Step-by-step explanation: It depends how your teacher thought how to solve this but the easiest way would be: 16.07 - 2.63 = 13.44 than 13.44 divided by 8= 1.68.

Answers

Answer:

885.45

Step-by-step explanation:

Testuo monthly payments will be around 885$

What is Interest

It is a fee paid for borrowing money or other assets.

• the amount borrowed is called the principal.

•  the interest is expressed as a percentage rate of the principal

for a given time interval.

It is given that

Value of the car = $32000

Time period of loan repayment = 36 months

T = 3 years

Rate of Interest = 6.71%

10% down amount from 32000  =  3200 $

So the amount he is putting for finance = 32000 - (0.1 × 32000)

                 

                                               = $28800

Rate of interest can be calculated from

I = P x R x T

I = Interest, P = Principle, R = Rate, T = Time

= (6.71 * 28800 * 3)/(100*12)

= $ 483.12

This is total interest for an year

In one month, rate of interest

= 483.12/12

 = $40.26

The principal amount that will be payable per month

= 28800/36

= $800

                                                           

Total amount payable will be

= $ ( 800 + 40.26 )

= $840

                                   

Hence, we can conclude, Tetsuo needs to pay $840.26 as monthly installments, so in the options given it is 885$

The point Q has coordinates (2,3)

A line perpendicular to QR is given by the equation 5x + 2y = 9
Find an expression for b in terms of a. W

Answers

Answer:

b= (2a+11)/5

Step-by-step explanation:

5x + 2y = 9

2y=9-5x

y= 9/2 - 5x/2

slope, m1= -5/2

for perpendicularity, m1 × m2 = -1

slope for QR= m2=

[tex] = - 1 \div \frac{ - 5}{2} = - 1 \times \frac{2}{ - 5} = \frac{ - 2}{ - 5} = \frac{2}{5} [/tex]

m2 is 2/5

[tex]qr = \frac{b - 3}{a - 2} [/tex]

[tex] \frac{2}{5} = \frac{b - 3}{a - 2} [/tex]

5(b-3)=2(a-2)

5b-15=2a-4

5b=2a-4+15

5b= 2a+11

[tex]b = \frac{2a + 11}{5} [/tex]

An expression for b in terms of a is b = (2a + 11)/5.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given an equation of a line 5x + 2y = 9 ⇒ 2y = - 5x + 9 ⇒ y = (-5/2)x + 9/2.

So, the slope of the line parallel to QR is the slope negative reciprocal of (-5/2) which is (2/5).

We know slope m = (b - 3)/(a - 2).

∴ (2/5) = (b - 3).(a - 2).

2(a - 2) = 5(b - 3).

2a - 4 = 5b - 15.

2a + 11 = 5b.

b = (2a + 11)/5.
