48 degrees remains
divide minutes by 60
36/60 = 0.6
then divide seconds by 3600
12/3600=0.003 ( to nearest thousandth)
now add them all up
48 +0.6 + 0.003 = 48.603 degrees
The slope of the equation is calculated as:
Where 
is the height of the upper part of the slope and 
is the height of the low er part.
So, the equation of the line is:
With this equation we can find the height of Alberto after having passed 10 sec.
After 10 seconds Alberto is 350 feet from the bottom of the slope.
Alberto's speed is:
The speed in miles per hour is:
You simplify it by doing distributive property like this
(4+2i)(3-i) =12-4i+6i-2i2
now add common like numbers
12+2i-2i2
Now on the i that is squared change the i to a -1 and get this
12+2i+2
Now again add common like numbers and get
14+2i that would be your answer
hope this helped
Answer: 7x - 5
Step-by-step explanation:
The expression given in the question is:
= 6x - 5 + x
We have to collect like terms. This will be:
= 6x + x - 5
= 7x - 5
