An elevator rises steadily up a skyscraper. After 4 s it is 33 m above the ground, 2 s later it is 47 m above the ground. Which equation models its position, y, with respect to time, x?

Answers

Answer 1

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

2. Railyn is saving for a laptop computer. She already has
$800 saved and plans to save $50 a week from her baby
sitting money. If the laptop she wants costs $1,150, how
many weeks will it take her to save enough to buy it?
a. Define the variable and represent the situation with
an equation.

Answers

x = number of weeks which is some positive whole number

50x = amount saved after x weeks, when saving $50 per week

50x+800 = add on the 800 she already has

The expression 50x+800 is the total money saved. We set this equal to the 1150 to set up the equation we're after

Answer:  50x+800 = 1150

  3)  x = 5

Step-by-step explanation:

When a transversal crosses parallel lines, all of the acute angles are congruent, and all of the obtuse angles are congruent. When it crosses at right angle, all of the angles are right angles.

2) All of the angles are right angles.

  11x +13 = 90

  11x = 77 . . . . . . subtract 13

g(x) = 3x-2


Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).


Part B: Which function has a greater y-intercept? Justify your answer.


Please hurry as I only have a few hours left too turn in :) Thank you.

Answers

Answer:

Use 2 points from he table to find the slope of f(x):

(0, -1) and (1, 7)

The slope is:

m = (7 - (-1))/1 = 8

The y - intercept is b = -1 according to point (0, -1).

Part A

The lines are:

f(x) = 8x - 1g(x) = 3x - 2

The f(x) has greater slope since 8 > 3 and greater y-intercept since -1 > - 2.

Part B

See above

a rectanglr has a perimeter of 18 cm. its length is 5 cm greater than its width. find the dimensions.

Answers

L=7 w=2

First write an equation to find the dimensions. You know l=5+w and p=18. Using this you can create the equation:
18=2(5+w)+2w

The 2s come from there being 2 sides that are the length and 2 sides that are the width.

Next solve for w. Distribute the 2, then add the common terms, next subtract the 10 and divide by 4.
18=10+2w+2w
18=10+4w
8=4w
W=2

Now that you have the width you can do one if two things to find the length. Either use the equation p=2l+2w or l=5+w

P=2l+2w
18=2l+2(2)
18=2l+4
14=2l
L7

L=5+w
L=5+2
L=7

The area of a rectangle is 33 m”, and the length of the rectangle is 5 m less than double the width. Find the dimensions of the
• rectangle

Answers

Answer:

Width: 5:5

Length: 6

Area: (6) (5.5 = 33m^2

Step-by-step explanation:

Width: x

Length: 2x - 5

(2x-5)(x) = 33

2x^2 - 5x - 33 = 0

(2x - 11) (x + 3) = 0

2x - 11 = 0

x = 11/2 = 5.5

x + 3 = 0

x = -3

[(2*5.5)-5](5.5) = 33
