Answer:
B
Step-by-step explanation:
<STR = <SRT Given the markings of the triangle
<STR + <STU = 180 Supplementary angles
(2x - 9) + 7x = 180 Remove the brackets
2x - 9 + 7x = 180 Combine
9x - 9 = 180 Add 9 to both sides
9x = 180 + 9 Combine
9x = 189 Divide by 9
9x/9 = 189/9
x = 21
Answer:
1.41 %
Step-by-step explanation:
Principal amount (P) = $500
Time (T) = 2 weeks = 2 * 7 days = 14 days
Interest = $80
So,
Interest = P*T*
=> 80 = 500 * 14 * 
=> 80 = 7000 * 
Flip the sides of the equation
7000 *
= 80
Multiply both sides by 100
7000 *
* 100 = 80 * 100
Cancel out the 100's on the top and bottom from the left side
7000 * R = 8000
Divide both sides by 7000
= 
Cancel out the 7000's on the top and bottom from the left side
R = 1.41 %
So, the periodic interest rate of the loan = 1.41 %
a) quadrant 1
there is the only place in the range between -pi and pi where both are positive
