Answer:
Step-by-step explanation:
A unit circle is defined as a circle of unit radius (that is the radius of the circle is equal to 1). In trigonometry, the unit circle is a circle with a radius of 1, while centered at the origin (0, 0) in the Cartesian coordinate.
In the unit circle below, we can see that the line touches the unit circle at point 
, therefore to find the tangent of theta, we use the formula:
From 8:25 am to 30 seconds past 8:29 am, there are 4.5 minutes. Her speed is calculated by dividing the distance of the post office from her house by the time.
Speed = 0.75 mile / 4.5 minutes = 1/6 mile / minute
Determining the number of minutes she will have to take in order to reach school,
Time = 3.42 mile / (1/6 mile/minute) = 20.52 minutes
Adding this to the initial time,
Final time = 8:25 am + 20.52 minutes
= 8:45 am and 31.2 seconds.
She will reach the school on time even without increasing her speed.
Answer:
Just list all the coefficients.
Step-by-step explanation:
one thing to know
If a variable is just there, like x, it's coefficient is always a one
1. (12 and 4)
2. (46 and 10)
3. (12 and 14)
4. (10 and 10)
5. (17 and 32)
6. (5,7 and -12)
7. (36 and 70)
8. (3,19 and 10)
9. (7 and 16)
10. (8 and 5)
11. (9 and 120)
12. (12 and 1)
13. (7,15 and 1)
14. (4,-8 and 12)
15. (6,17, and -35)
You take the total number of picture and multiply it by .12, which will get you the total number of black and white photos only.
600(.12)= 72
