Answer:
I and IV
Step-by-step explanation:
cosine is positive/greater than 0 in quadrants I and IV. Its just a rule of the unit circle.
Can remember by All Star Trig Class
meaning all the trig funtions are positive in quadrant I
sin is positive in II
tan is positive in III
and cos is positive in IV
Hey there!
![\large\boxed{40\%}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B40%5C%25%7D)
To find percent error, we find the difference between the prediction and the actual value. We take that difference, divide it by the prediction, and multiply it by 100.
So let's find the difference.
42 - 30 = 12
Divide the difference, which is 12, by 30.
12 ÷ 30 = 0.4
Multiply this by 100 to get the percent.
0.4 x 100 = 40
The percent error is 40%.
Hope this helps!
Answer:
228.947
Step-by-step explanation:
#1
rule : r - 12
Missing number = 25 (37-12 = 25)
#2
rule: a + 34
Missing number = 43 (9+34 = 43)
#3
rule: s - 5
Missing number = 20 (25-5 = 20)
#4
rule: b+16
Missing number = 0 (0+16= 16)
#5
rule: w+3
Missing number = 9 (6+3= 9)
#6
rule: n-11
Missing number = 22 (33-11= 22)
#7
15 - n when n = 9
15 - 9 =6
#8
32 more than a number d:
32 +d
answer is C. 32+d
#9
Variable is an unknown value. So you need to solve that unknown value in the problem.
Proshen it out evenly so evwryone gets the same amount or divide it by 300 people
