Use scalar multiplication to determine the coordinates of the vertices of the dilated figure. Triangle with vertices A(1,8) B(6,1) and C(-9,4) with scale factor 5/2

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.

Is there an x intercept in the equation 60*1.15^x

Summary statistics given for independent simple random samples from two populations. use the pooled t-interval procedure to obtain specified confidence interval. x1=71.6, s1=3.9, n1=11, x2=67.9, s2=3.4, n2=9 determine a 99% confidence level.
