Answer:
1/3 of the day
Step-by-step explanation:
8/24 simplifies to 1/3
The formula for illuminance is given by
E = I / d^2
This formula only holds true for one-dimensional illuminance
The problem asks for the illuminance across the floor. We need to use two variables, x and y.
From Pythagorean Theorem
d^2 = x^2 + y^2
and from Trigonometry
x = d cos t
y = d sin t
The function for the illuminance can be represented by the composite function
E = I cos² t / x²
and
E = I sin² t / y²
The boundary of these functions is:
<span>0 < t < 8
So, the value of t must be in radians and not in degrees</span>
Answer:
I believe it would be 50
Step-by-step explanation:
If those 3 hours are included in those 12 to get there, then you'd want to subtract that to get your actual time spent driving. That would leave you with 9. Then, you'd divide that by 450 to get your answer. (This is if those 3 hours are included in that 12 hour time frame.)
First off, you need to have your ys on the same side. Here's how to do it:
4y + 15 = -5y + 9
4y + 5y = 9 - 15 (once a number goes to the other side, it changes its sign)
9y = -6
y = -6/9
y = -2/3
The correct answer is B. -2/3
I think u have to multiply 4 times .07 then that get you .28 cents
