Urgent the earth completely rotated on its axis once every 24 hours a) how long does it take for it to rotate 310 degrees? b) how long does it take to rotate 5 radians? c) the diameter of the earth is approximately 7920 miles how far will a point on the equator rotate in two hours? show all work. give answers to the nearest hundredth include the units in your response. , i really need with this. i’ll give brainliest to best answer!

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?

Ihonestly have no clue if it's each or none.
