Let's say α is the angle that subtends from the top of the screen to horizontal eye-level.
Let β be the angle that subtends from the bottom of the screen to horizontal eye-level.
tanα = (22 + 10 - 4) / x = 28/x
α = arctan(28/x)
tanβ = (10 - 4) / x = 6/x
β = arctan(6/x)
Ɵ = α - β
Ɵ = arctan(28/x) - arctan(6/x)
(b.)
tanƟ = tan(α - β) = (tanα - tanβ) / (1 + tanα tanβ)
tanƟ = (28/x - 6/x) / [1 + (28/x)(6/x)]
tanƟ = (22/x) / [1 + (168/x²)]
tanƟ = 22x / (x² + 168)
Ɵ = arctan[22x / (x² + 168)]</span>
Answer:
See below
Step-by-step explanation:
To get the fraction from mixed number you just need to take the number standing alone, multiply with the denominator and add with the numerator and keep it on top with the denominator in place to turn it into a fraction.
For example, [2]3/4 = 2*4 + 3 = 11 => the fraction is 11/4.
31
just substitute -8 for all x
process here:
f(x) = -3x + 7
f(-8)= -3(-8) + 7
<u>Answer:
</u>
In 3 hour 15 minutes Dennis will walk 9.2072 miles.
<u>Solution:
</u>
It is given that Dennis can walk 2.833 miles each hour. We have to find how far will he walk in 3 hours 15 minutes.
We first convert 15 minutes in hour. To convert 15 minutes in hour we divide 15 by 60.
Therefore 3 hours 15 minutes can be written as 
Now,
In 1 hour dennis can walk 2.833 miles
Thus in 3 hour 15 minutes Dennis will walk 9.2072 miles.
