Please show work. -5/4 mult. 2, -2/3 a) f(x) = 48x^3 + 152x^2+155x+58 b) f(x) = 48x^3 + 152x^2+162x+50 c) f(x) = 48x^3 + 152x^2+155x+52 d) f(x) = 48x^3 + 152x^2+155x+50

With finding limits of multi variable !

Find the magnitude, correct to two decimal places, made by each of the following with positive direction of the x axis a) y= x the answer is 45° but i don’t know how

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
