An 11 foot ladder leans against the side of a house. The bottom of the ladder is 6 feet from the side of the house. How high is

Mariulka [41]

Using Pythagoras Theorem,
(b is the length of the ladder from the ground)
11x11=6x6+(b^2)
121-36=(b^2)
85=(b^2)
b= 9.219544457292887
b is approximately 9.2

A car travels at an average rate of speed of 60 miles per hour for 7 1/2 hours. How many miles doesn’t this car travel?

Galina-37 [17]

Distance = rate x time

distance = 60 miles per hour x 7 1/2 hours

distance = 450 miles

Answer:

A. Slope is -12 feet per second

B. Yes, it is constant.

<u>Skills needed: Linear Equations, Substitution and Division</u>

Step-by-step explanation:

1) Solving Part A (we need to find the slope):

The slope is $\frac{y_2-y_1}{x_2-x_1}$ --> $y_1$ , $y_2$ , $x_1$ , and $x_2$ are all values from the table. We know that the left column is the x-values, and the right column is the y-values as that is the conventional way of depicting them.

2) Using the y-values of 1150 and 1090, and their corresponding x-values (5 and 10 respectively), we can get the slope:

- $\frac{y_2-y_1}{x_2-x_1}$ ==> $\frac{1090-1150}{10-5}$ ==> $1090-1150=-60, 10-5=5$ ==> $\frac{-60}{5}$

$\frac{-60}{5} =-12$ , so the slope is -12.

==================================================================

1) Part B (analysis)

We can see that no matter what 2 y-values and their corresponding x values we use, the slope always is the same. This means that the rate of change is constant.

A certain brand of laundry detergent comes in two sizes. The smaller size is 24-oz and costs $3.99. The larger size is 64-oz and

vitfil [10]

$3.99/24oz= $0.16/oz (smaller size)
$6.99/64oz= $0.10/oz (larger size)

The larger size has the lower unit costs.
