Answer:
2.39 x 10^5 miles
Step-by-step explanation:
Although it is not usually written, there is always a .0 at the end of a number unless there is a specific decimal that was given.
So, the number here is 239,000.0 and if you count the number of spaces that the decimal needs to move in order to be in the correct spot for scientific notation (which is always after the first number), there is 5 spaces.
Therefore the answer is 2.39 x 10^5 miles.
Given:
y = mx + b
m = slope
b = y-intercept.
m = 1.35
x = 13
25.43 = 1.35(13) + b
25.43 = 17.55 + b
b = 25.43 - 17.55
b = 7.88
y = 1.35(19) + 7.88
y = 25.65 + 7.88
y = 33.53
The monthly cost for 19HCF is $33.53
898 rounded answer is 900
The values for x and y are respectively given as
This is further explained below.
<h3>What is the values for
x and y ?</h3>
Generally, the equation for secent is mathematically given as

Therefore

80 = 130-x
x = 50
b) To Solve for y Now we find a measure of arc CD
ArcCD = 360-130-50
ArcCD = 180
In conclusion,(1/2) of the arc measure is equal to the angle that is on and inside a circle.
y = 180/2
y= 90
