PLEASE HELP The number of bacteria in a refrigerated food product is given by N(T)=24T^2-180T+97, 4 < T < 2, 4 When the food is removed from the refrigerator, the temperature is given by T(t)=3t+1.3, where t is the time in hours.

Find the composite function N(T(t)) :
N(T(t))=
Find the time when the bacteria count reaches 8442.
Time Needed = hours

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

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
