12) Em um experimento, uma substância líquida foi exposta a uma variação de temperatura durante 8 minutos. Nesse experimento, a temperatura T, em graus Celsius, dessa substância, variou
em função do tempo m, em minutos, de acordo com a relação T(m) = – 5m2
+ 40m, sendo que a maior
temperatura atingida por ela correspondeu ao seu ponto de ebulição.
Qual foi o ponto de ebulição, em graus Celsius, dessa substância nesse experimento?
A) 4 °C.
B) 8 °C.
C) 40 °C.
D) 80 °C.
E) 160 °C.​

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
