Answer:
D. 0° to 90°
Step-by-step explanation:
If we see curve of sin(o) on coordinate, we will notice that value of sin curve increases from 0 to 90 degrees and then decreases from 90 to 180 degrees.
Hence option D is correct.
Alternatively
we see that
sin 0 = 0
sin 30 = 1/2
sin 45 = 1/
sin 60 = 
sin 90 = 1
Thus, we see that value of sin is increasing from 0 to 90
now lets see value of sin from 90 to 180
sin 90 = 1
sin 120 = 
sin 135 = 1/
sin 150 = 1/2
sin 180 = 0
Thus, we see that value of sin is decreasing from 90 to 180.
Answer:
Pie chart
Step-by-step explanation:
Given that a professor has kept records on grades that students have earned in his class
He wants to examine the percentage of students earning the grades A, B, C, D, and F during the most recent term,
We have to find which kind of plot could he make
Box plot gives comparison for interval of scores this is to some extent helpful to find out the percentage of students getting a range of scores
Timeplot is irrelevant here. Dot plot will not be of much use.
Histogram is to some extent useful as box plot
But the best one is pie chart giving easy visual comparison for various grades A, B,C,D,E and F
<span> x=<span><span><span><span>3</span> and </span></span>y</span></span>=<span>2 to check use the first equation y=5x-13 you plug in x which is 3 5 times 3 equals 15 15-13 equals 2 y=2</span>
Answer:
line segment BE
Step-by-step explanation:
Parallel lines are lines that never cross. In this case, the two parallel lines are AC and DF. A line segment is part of a line that has a point at either end. The only segment which crosses lines AC and DF is segment BE.
Also, if you look at the answer choices, the first two indicate a line ↔ above the letters, which represents a line that doesn't end, while the other two choices just have a line to indicate a segment.
To solve, set up a proportion
3.25 cups x cups
---------------- = ---------------
13 servings 28 servings
Now cross multiply
13x = 28 * 3.25
Simplify.
13x = 91
Divide both sides by 13
x = 7 cups
To check your answer, use proportions again, but change the left side to 4.5 cups over 18 servings, use the same steps, if the answer is the same as above, then the answer is correct
