Answer:
f(x) = -2x³ +17x² -32x +23
Step-by-step explanation:
It is usually sufficient to try the values of a couple of points in the offered answer selections to see which one fits.
You have not provided any choices, so I have used the polynomial regression function of a graphing calculator to compute the cubic that will represent these ordered pairs exactly.
Answer: 379.94
Step-by-step explanation: To find the area of a circle, you do radius squared times pi. To find the radius, divide the diameter in half. So 22 divided by 2 is 11. 11 squared is 121. Then multiply 121 by 3.14. That equals to 379.94
Population mean = (7+8+6+6+6+4+4+1+2+7+6+1+1+1+3+3+5+4+5+7) / 20 = 87/20 = 4.35 <==
sample mean = (4+5+7) / 3 = 16/3 = 5.33 <==

Answer:
c. sin 30 is positive and sin -30 is negative
Step-by-step explanation:
Picture the unit circle (which is attached). <u>Sine is like the y-coordinate.</u> And -30 and 30 on the unit circle both form equally-sized triangles, but -30 is underneath the x-axis, so it has a <u>negative y-coordinate.</u> 30 is above the x-axis, so it has a <u>positive y-coordinate.</u>
