You have to plug in the given numbers and perform each operation. Let me know if you have questions. The answers are circled.
We use the fact that x2+y2=1 This is the equation of the unit circle.
We know that x=-4/5, so plug this in and solve for y
x2+y2=1 <span>(−4/5)^2+y2=1</span> 16/25+y2=1 y2=1−16/25 y2=9/25 <span>y=−square root of 9/ 25</span>
y = -3/5
7 x 6 = 42 x 5 = 210 x 8 = 1,680 x 4 = [ 6,720 ]
Answer:
The second table.
Step-by-step explanation:
In the first table, the speed goes from 45 down to 43; then down to 41; then up to 42; then up to 43. It decreases and then increases. This is not the correct table.
In the second table, the speed goes from 45 up to 47; then up to 49; then down to 48; then down to 47. It increases and then decreases; this is the correct table.
To verify, we check the last two tables. The third table stays at 45, then decreases to 43 and 41. This is not correct.
The last table decreases from 45 to 43, then decreases to 41, then stays constant. This is not correct.
The second table is the only correct one.
Max is simply incorrect because he's stated his inequality in the opposite fashion that he should have:
36,594 is greater than 5,980
because the 3 in 36,594 represents the ten thousands place and the 5 in 5,980 represents the thousands place (which is a power of 10 less than the ten thousands place)
