The equation of a line is y=-5/8x A - slope = -5 ; y-intercept:8
B - slope = -5/8 ; y-intercept : none
C - slope -5/6 ; y-intercept : 0
D - slope = 0 ; y-intercept: -5/8

The reflexive property of congruence lets you say that ∠pqr ≅

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.

The volume of a spherical hot air balloon v(r) = 4 3 ? r3 changes as its radius changes. the radius is a function of time given by r(t) = 3t. find the instantaneous rate of change of the volume with respect to t at t = 2.
