A = (b1 + b2)h Solve for b1

inn [45]

Answer:

b1 = A/h - b2

Step-by-step explanation:

Given equation:

A = (b1 + b2)h

Solving for b1:

A = (b1 + b2)h ⇒ divide both sides by h
A/h = b1 + b2 ⇒ subtract b2 from both sides
b1 = A/h - b2 ⇒ answer

1. Considere as funções f e g, ambas com domínio Z, dadas por f(x) = x²- 2x e g(x) = x³-1. Associe as colunas e assinale a alter

Greeley [361]

Answer:

(A)C,D,A,B

Step-by-step explanation:

$f(x) = x^2- 2x\\g(x) = x^3-1$

$f(-2) = (-2)^2- 2(-2)\\=4-(-4)\\=4+4\\=8$ (C)$

$g(-2) = (-2)^3-1\\\=-8-1\\=-9 $(D)$

$f(-1) = (-1)^2- 2(-1)=1+2=3\\g(3) = (3)^3-1=27-1=26\\f(-1) + g(3)=3+26\\=29$ (A)$

d) f(5) : g(2)

$f(5) = (5)^2- 2(5)=25-10=15\\g(2) = (2)^3-1=8-1=7\\f(5) :g(2)=15/7$ (B)$
