Answer:
40 mph
Step-by-step explanation:
Recall that the slope of this line is also the speed at which the car was driven, and that, in turn, is:
240 miles
------------------- = 40 mph
6 hrs
The best thing to do is to find a common denomiantor, and you can do this by listing the multiples.
5- 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85
17- 17 34 51 68 85 102
The lowest common multiple is 85, so you've got to multiply the first fraction by 17, and the second by 5.
3x17= 54, 5x17= 85 and 3x5= 15, 5x17= 85.
this then becomes 54/85 and 15/85, when you're adding fraction, you add the denominators- 54+15= 69, therefore, the fraction becomes 69/85
Hope this helps :)
Answer:
Step-by-step explanation:
The area of a triangle is calculated by the expression as follows:
Area = bh / 2
where b is the base and h is the height.
We can calculate the hypotenuse as follows:
210 = b(35) / 2
b = 12
hypotenuse = sqrt(35^2 + 12^2)
hypotenuse = 37 in
So I would factor it first like so:
P(x) = x^3 - 4x^2 +3x - 12
=x^2(x-4)+3(x-4)
=(x^2+3)(x-4)
Then set the factored form equal to 0 because you want the company to break even so:
P(x)=0
0=(x^2+3)(x-4)
0=x-4
4=x
x^2 +3 =0 has no real solution
So x equals four so the company will break even in 4 years
