Answer:
sin(x) = -sqrt2/2
tan(x) = -1
Step-by-step explanation:
Because it is between 270 and 360, sin is negative, so it is -sqrt2/2.
tan(x) is sin(x)/cos(x), so it is just -1.
Answer:
m = {-6, -4}
Step-by-step explanation:
<u><em>Subproblem 1:</em></u>
Set the factor '(6 + m)' equal to zero and attempt to solve:
Simplifying
6 + m = 0
Solving
6 + m = 0
Move all terms containing m to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + m = 0 + -6
Combine like terms: 6 + -6 = 0
0 + m = 0 + -6
m = 0 + -6
Combine like terms: 0 + -6 = -6
m = -6
Simplifying
m = -6
<u><em>Subproblem 2:</em></u>
Set the factor '(4 + m)' equal to zero and attempt to solve:
Simplifying
4 + m = 0
Solving
4 + m = 0
Move all terms containing m to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + m = 0 + -4
Combine like terms: 4 + -4 = 0
0 + m = 0 + -4
m = 0 + -4
Combine like terms: 0 + -4 = -4
m = -4
Simplifying
m = -4
Answer:
CP = Rs 500
Step-by-step explanation:
Given that,
Selling price of a book, SP = Rs 550
Profit percent = 10%
We need to find the cost price of the book. The formula for profit percent is given by :

So, the cost price of the book is Rs 500.
15 x 95 = 1425
1875 - 1425 = 450
450/25 = 18 items were sold at $25 a piece
16.25pi
You can get this by first solving for volume of a cylender formula for the 1.5 radius of the outer shell. Then solve for a 1 radius of the inner empty portion. Then subtract the second from the first.
