Answer:
Step-by-step explanation:
Woke up = 7:30 AM
<u>Time to:</u>
- Get ready = 14 min
- Finish breakfast = 9 min
- Commute to school = 39 min
<u>Altogether:</u>
= 14 + 9 + 39 min
<h3>= 62 minutes </h3>
(As we know that, 1 hour = 60 minutes)
So,
<h3>62 minutes = 1 hour 2 minutes</h3>
<u>Time he reached the school:</u>
7 hr 30 min + 1 hr 2 min
Combine like terms
7 hr + 1 hr + 30 min + 2 min
<h3>8 hr + 32 min</h3>
OR
<h3>8:32 AM</h3>

By looking at the graph, we can tell that the slope is rise / run = 2 / -2 = -1
Slope = -1
We can also see that the y intercept is -1 or in point form (0,-1) Look at the line, it crosses the y axis between 0 and -2 at -1.
Answer:
the second one
Step-by-step explanation:
pi/2 to pi
pi/2 is 90 degrees and pi is 180 and 125 is right in between that interval
Answer:
1
Step-by-step explanation:
Use the form for the factoring of the sum of cubes.
To make this easier to write, we'll use the substitutions ...
a = sin(θ), b = cos(θ)
It looks like you may want to simplify ...
(a³ +b³)/(a +b) +ab
= ((a +b)(a² -ab +b²))/(a +b) +ab
The factors of (a+b) cancel. In this case, we know that a² +b² = 1, so this becomes ...
= (1 -ab) +ab
= 1
