Problema de Área Um terreno retangular possui 25 metros de comprimento e 15 metros de largura. Qual é a área do terreno em metros quadrados e em hectares? (1 hectare \( \left.=10.000 \mathrm{~m}^{2}\right) \) Resposta esperada: O aluno deve calcular a área \( \mathrm{em}^{2} \mathrm{e} \), em seguida, converter para hectares.

Hallar una ecuación de la hipérbola que tiene focos en \( (-15,0) \) y \( (15,0), y \) asíntotas \( y=\frac{3}{4} x \) y \( y=-\frac{3}{4} x \)

5) The amount of electricity utilized, calculated by multiplying power in kilowatts by time in hours. \( \begin{array}{llll}\text { A) hours per kilowatt } & \text { B) kilowatts per hour C) kilowatts per second } & \text { D) } \\ \text { kilowatt-hours } & \end{array} \)

Linda deposits \( \$ 90,000 \) into an account that pays \( 4 \% \) interest per year, compounded annually, Bob deposits \( \$ 90,000 \) into an account that also pays \( 4 \% \) per year. But it is simple interest. Find the interest Linda and Bob earn during each of the first three years. Then decide who earns more interest for each year, Assume there are no withdrawals and no additional deposits.

Add and simplify. \( (-3+6 i)+(7+8 i) \)

Evaluate the expression for \( x=2 \) and \( y=2 \). \( y^{\left(x^{2}\right)} \)
