At the moment a hot cake is put in a cooler, the difference between the cake's and the cooler's temperatures is 50 degree celsius. this causes the cake to cool and temperature difference loses 1/5 of its value every minute. write a function that gives the temperature difference in degrees celsius, d(t) minutes after the cake was put in the cooler.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu

54/3 is 18 so 18 is your answer

yep b and c r the correct got it! : )
