Scientific notation is another way to write a number. In scientific notation, the letter E is used to mean "10 to the power of." For example, 1.314E+1 means 1.314 * 101 which is 13.14 .
A) Let x stand for time, y stand for velocity.
We are given the points (2,50), (6, 54). We can make a line using the slope intercept form
y = mx + b.
slope is (54 - 50)/(6-2) = 4/4 = 1
y = 1x + b
plug in point (2,50) to find b
50 = 1(2) + b
50-2 = b
48 = b
the equation is y = 1x + 48
Make standard form.
<span>x - y = -48

Table Is attached.
Good Luck!

Step-by-step explanation:
1.5×60=90 steps per min
90×60=5400 steps per hour
Answer:
38.57 feets
Step-by-step explanation:
Given that:
Height of monument, h = 300ft
Shadow of monument, s = 210 ft
Shadow of tree, s = 27ft
Height of tree, = x
Using the relation :
Height / shadow = height / shadow
Monument = tree
300 / 210 = h / 27
Cross multiply
300 * 27 = 210 * h
8100 = 210h
h = 8100 / 210
h = 38.57 feets
Answer:
x = 30
Step-by-step explanation:
In order for the lines to be parallel,
2x + 20 = 80
2x = 60
x = 30
