Please please help worth lots of points Given ƒ(x) = x - 1, complete Parts A and B. Part A: Using the table provided, create fiv
Gemiola [76]
Wouldn’t you just for part a, insert different x values and solve to get your y value. and do that over and over again with different numbers to create a data table. and then for part b you’ll just make a graph and put down the points. so for the first slot, do 0 for x. y will equal -1 after solving, so your first plot for part b can be (0,-1) and continue on from there

Svet_ta [14]

Answer:

$182.91

Step-by-step explanation:

136.50 times 0.14 (14%) is 19.11

136.50 times 0.2 (20%) is 27.30

13650+19.11+27.30=182.91

The flash of lightning travels at the speed of light, which is about 186,000 miles per second. The sound of lightning (thunder)
4vir4ik [10]

Answer:

A.  <u>Distance of the lightning after 4 seconds = 744,000 miles</u>

<u>B. Distance of the lightning after n seconds = 186,000 * n</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed of lightning = 186,000 miles per second

Speed of sound = 750 miles per hour

2. A.  If you see a flash of lightning, then hear the thunder 4 seconds later, how far away is the lightning?

Distance of the lightning after 4 seconds = 186,000 * 4

<u>Distance of the lightning after 4 seconds = 744,000 miles</u>

<u>B. Now let’s generalize that result. Suppose it takes n seconds to hear the thunder after a flash of lightning. How far away is the lightning, in terms of n?</u>

<u>Distance of the lightning after n seconds = 186,000 * n</u>

Drow two different rectilinear shapes each with an area of 6 squares.
ArbitrLikvidat [17]

Answer:

We can draw a rectangle and a square.

First the square:

The area of a square of sidelength L is:

A = L^2

So if the area of this square must be 6 square units, we get:

6 square units = L^2

L = √(6 square units) = 2.45 units

Now for a rectangle, we know that for a rectangle of length L and width W, the area is:

A = L*W

Now let's give the width a value of 1 unit, then W = 1unit

A = L*1 unit

And we know that the area must be of 6 square units, then:

6 square units = L*1 unit

(6 square units)/(1 unit) = L

(6 units) = L

The drawings (these are not exact ones, i'm doing them with a mouse) of the images can be seen below.
