5 pontos
A∩B={x∈ R / 1/10 < x ≤ 1}
A∩B={x∈ R / 1/10 ≤ x≤1}
A∩B={x∈ R / -3 ≤ x ≤ 1}
A∩B={x∈ R /-3 < x ≤ 1}

Answer 1

$\Large\boxed{\begin{array}{l}\sf A=[-3,1]\\\sf A=\{x\in\mathbb{R}/-3\leqslant x\leqslant1\}\\\sf B=~~\bigg]\dfrac{1}{10},\dfrac{3}{2}\bigg]\\\\\sf B=\bigg\{x\in\mathbb{R}/\dfrac{1}{10}<x\leqslant\dfrac{3}{2}\bigg\}\\\\\sf A\cap B\bigg\{x\in\mathbb{R}/\dfrac{1}{10}<x\leqslant1\bigg\}\end{array}}$
