Answer:
Using a globe and some string might be more convenient. A great circle is the shortest path between any two points on the earth's surface.
I hope I helped! ^-^
Hello :
f<span>unction is linear when are the form : y = ax +b
</span><span>function is linear constant are the form : y = b</span>
Answer:
Slope is the charge per hour, y-intercept is the flat fee earned by Nicole and the equation to find the cost per hour is ![C=m(h)+3](https://tex.z-dn.net/?f=C%3Dm%28h%29%2B3)
For
hours of babysitting amount earned is
.
Step-by-step explanation:
From the given data lets assign time on x-axis and the amount earned on y-axis.
We have to choose two points.
and ![(x,y)=(5,28)](https://tex.z-dn.net/?f=%28x%2Cy%29%3D%285%2C28%29)
By applying point slope form we have to find the slope of the points.
Slope (m) ![= \frac{y-y_1}{x-x_1} =\frac{28-18}{5-3} =\frac{10}{2} =5](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7By-y_1%7D%7Bx-x_1%7D%20%3D%5Cfrac%7B28-18%7D%7B5-3%7D%20%3D%5Cfrac%7B10%7D%7B2%7D%20%3D5)
Here slope is representing per hour charge of Nicole for babysitting.
Now lets find the y-intercept value by plugging the values of
in standard equation of line that is
,equivalent to
where
is the y-intercept.
The equation for cost (C),
,
is the number of hours.
![b=C-m(h), b=28-5(5), b=28-25=3](https://tex.z-dn.net/?f=b%3DC-m%28h%29%2C%20b%3D28-5%285%29%2C%20b%3D28-25%3D3)
This y-intercept
is representing the flat fee Nicole will charge for babysitting.
Now
For
hours cost we will put
in the equation of cost.
![C=5h+3,C=5(5)+3=28\$](https://tex.z-dn.net/?f=C%3D5h%2B3%2CC%3D5%285%29%2B3%3D28%5C%24)
For
hours of baby sitting Nicole will earn an amount of ![C=5(5)+3=28\$](https://tex.z-dn.net/?f=C%3D5%285%29%2B3%3D28%5C%24)
So our final answers are equation of cost
, y-intercept is the flat fee and slope is the charge per hour.For
hours amount earned is
.
Answer:
There are many areas but
Step-by-step explanation:
Area of square is L × W
where you multiply both length × width you get the answers squared
Area of a cube is L × W × H
this is where you multiply all length × width × height and get the answer cube
