Answer:
D -24/25
Step-by-step explanation:
sin(2x) = 2sin(x)cos(x)
cos(x) = ⅘
sin²(x) = 1 - cos²(x) = 1 - (⅘)²
sin²(x) = 9/25
sin(x) = -⅗
(Because 4th quadrant)
sin(2x) = 2(-⅗)(⅘)
= -24/25
The 6 in 621 is in the hundred's place, so alone it would equal 600.
However, the 6 in 6,420 is in the thousand's place, so it alone would equal 6,000.
The question is asking how many times smaller is the value of 6 in these two numbers. Therefore, you need to divide 6,000 by 600.
Your answer should be 10.
To find the total you would need to multiply the 31.75 by w to get the total amount of his weekly deposits, then that would get added to the initial amount of 249.45
The equation would be 249.45 + 31.75w
You should buy 106.25 ft 2, because if you multiply 8.5 times 12.5 you would get that answer, which is the area of the wall.
