Newton's Law of Cooling expresses the relationship between the temperature of a cooling object y and the time t elapsed
since cooling began, in minutes. This relationship is given by y-ae+c, where c is the temperature of the medium
surrounding the cooling object, a is the difference between the initial temperature of the object and the surrounding
temperature, and k is a constant related to the cooling object.
-The initial temperature of a liquid is 160°F. When it is removed from the heat, the temperature in the room is 76°F. For this
object, k - 0.23. Use Newton's Law of Cooling to find the temperature of the liquid after 15 minutes.
a. 73.6°F
C. 79.2°F
b. 78.70F
d. 83.5°F

Rose drew a regression line for this paired data set. her line passed through (1, 2) and (3, 5) . what is the equation of rose's regression line?

Can someone me do math because i am having a breakdown rn because i don’t get it

Someone answer this asap rn 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)) =
