Please use Matlab fomat.
(Use format rat) Recall [x]B denotes the coordinate vector of x with respect to a basis B for a vector space V . Given two bases B and C for V , P C < B denotes the change of coordinates matrix, which has the property that
P_C < B [x]B = [x]C for all x ∈ V.
It follows that
P_ B < C = (P_ C < B)^-1 .
Also, if we have three bases B, C, and D,
then (P_D < C)(P_C <B) = P_D < B .
Each of the following three sets is a basis for the vector space P3:
ε = {1, t, t^2 , t^3 } ,
B = {1, 1 + 2t, 2 − t + 3t^2 , 4 − t + t^3 } , and
C = {1 + 3t + t^3 , 2 + t, 3t − t^2 + 4t^3 , 3t} .
(a) Find and enter the matrices P = P_ε < B and Q = P_ ε < C

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3

Now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
