Answer:
A: 85%, 2
, 3.24, 
B: covert numbers into percent
Step-by-step explanation:
<u>Part A</u>
We have:
, 2, 85%, 3.24 --> let's convert them into percentages like the 85, to determine which one is greatest/least:
85% --> 85% (already a percent)
--> to convert into percent: (19÷4) x 100 = 475%
2 --> convert first into improper fraction then into percent: (11/5) x 100 = 220%
3.24 --> multiply by 100: 3.24 x 100 = 324%
From least to greatest: 85%, 220%, 324%, 475%
= 85%, 2, 3.24,
Part B:
In part A, to determine the numbers from least to greatest, we rewrote the numbers all into percentage form by first converting into decimal form and then multiplying by 100.
Answer: The graph is attached.
Step-by-step explanation:
1. Solve for y, as following:
2. The equation of the line in slope intercept form is:
Where m is the slope and b is the y-intercept.
3. In this case the equation of the line is:
then:
4. Find the x-intercept. Make y=0. Then:
5. Then, plot the line that passes through the points (0,7) and (4.9, 0).
6. The symbol of the inequality is < therefore, the line must be dashed and indicates that the region under the line must be shaded.
Then you obtain the graph attached.
Answer:
Step-by-step explanation:
cos x=sin 2x
sin 2x-cos x=0
2 sin x cos x-cos x=0
cos x(2 sin x-1)=0
either cos x=0
or
2 sin x-1=0
