Answer:
Step-by-step explanation:
Let the equation of the cosine function is,
y = Acos(Bx)
From the graph attached,
A = Amplitude =
= 1
B =
B =
B =
B = 4
Therefore, equation of the cosine wave given in the graph will be,
y = 1.Cos(4x)
y = Cos(4x)
If you are trying to find the answer for x it would 20
A there is one outlier that indicates an unusually large number of players on that team
Answer:
a. 440
b. 100
c. 1800
d. 320
Step-by-step explanation:
a. $7000 is 3000 +4000 so this falls in two pay ranges.
0.04(3000) + 0.08(4000) = 120+320 = $440
b. $2500 is lower than 300 so it falls in only one pay range.
0.04(2500) = $100
c. 12,000 is greater than both 3000 and 8000 so this falls in the last pay range.
0.15(12000) = $1800
d. $5500 is 3000+2500 so this falls in two pay ranges.
0.04(3000) + 0.08(2500) = 120+200 = $320
Answer:
8) No solution
9) n > -5 <em>(View explanation for info on how to graph)</em>
Step-by-step explanation:
<em><u>Question 8</u></em>
<em><u /></em>
<u>24+6k < -6(-4-k)</u> - Solve and graph
1) Distribute -6 to -4 and -k:
24+6k < 24+6k
2) Subtract 6k from both sides:
24<24
^ We know the following is false, therefore there is no solution to question 8.
<em><u>Question 9</u></em>
<em><u /></em>
<u>-2n-40 < 5(6+n)+7n</u> - Solve and graph
1) Distribute 5 to 6 and n:
-2n-40 < 30+5n+7n
2) Combine alike terms:
-2n-40 < 30+12n
3) Add 2n to both sides:
-40 < 30+14n
4) Subtract 30 from both sides:
-70 < 14n
5) Divide both sides by 14:
n > -5
6) To graph, plot an OPEN CIRCLE (<em>don't fill in the circle)</em> at point -5 and then draw an arrow pointing to the right!
