Answer:
x = π/2, 7π/6, or 11π/6
Step-by-step explanation:
sin² x − cos² x − sin x = 0
Use Pythagorean identity to write cosine in terms of sine.
sin² x − (1 − sin² x) − sin x = 0
sin² x − 1 + sin² x − sin x = 0
2 sin² x − sin x − 1 = 0
Factor:
(2 sin x + 1) (sin x − 1) = 0
Solve:
sin x = -1/2 or 1
x = π/2, 7π/6, or 11π/6
The area is 73. You have to find the area of both triangles using the formula a = 1/2bh. The shaded triangle is 108 square yards but because another triangle is cut out of it, we need to subtract the area of the white triangle from the shaded triangle. The area of the white triangle is 35. So now we have 108-35 =73. That’s how i got 73.
Answer:
P(2)=0 then x-2 is a factor of P(x)
Step-by-step explanation:
To see if (x-2) is a factor just plug in 2 for x into the polynomial expression.
2(2)^3-3(2)^2-17(2)+30
2(8)-3(4)-34+30
16-12-34+30
4-34+30
-30+30
0
Since P(2)=0 then x-2 is a factor
Answer:
The correct answer is A. $385.
Step-by-step explanation:
Since Corey, Billy, and Shea own a house repair and update business, and the number of hours that each person spent painting and doing repair work on the same house is listed below.
• Corey: 4.25 hours
• Billy: 7.75 hours
• Shea: 10.5 hours
And since they earned a total of $ 1,100 for the job and put 25% of the money earned in an account for future expenses, to determine how much money Shea received if they divided the money proportionally based on the number of hours each worked is owed perform the following calculation:
1100 x 0.75 = 825
10.5 + 7.75 + 4.25 = 22.5
22.5 = 100
10.5 = X
10.5 x 100 / 22.5 = X
1050 / 22.5 = X
46.666 = X
825 x 0.4666 = X
384.99 = X
Therefore, Shea received $385.
