Answer: 299x^2 I think I hope we help you
Answer:
Find length opposite to 30deg
Opposite = tan(30)*42
= 24.2
Whole side = 24.2+10
Find angle of 0 + 30deg: (say x)
Tan(x) = 33.2/42
Arctan(0.79) = x
x = 38.3
The angle to find:
38.3-30:
8.3
The angle is 8.3deg.
Answer:
52 miles per hour
Step-by-step explanation:
Firstly, It is important to point out that it is Average speed. The Average speed throughout all the way the car traveled.
And this is may calculated by a simple formula or if you'd rather by a proportion. Let's pick this simple formula, what's going to be useful.
Let's do the math!
Average speed = Δs/Δt
Δs = Variation of Space (given in miles) =156 -0
Δt =Variation of Time (given in hours) =3-0
Average Speed = 156-0/3-0 =156/3 =52 miles per hour
It is important to say, Average speed, is a rate so it is given in miles per hour
X^2 + 9x + 8 = 0
To find the factors we need to find two number that multiply to equal 8 but add to equal 9.
8 = 1*8 9 = 1+8
(x + 1)*(x + 8) = 0
Answer:
3 number
