where, N represents the number of bacteria after 'h' hours.
So, we have given that there are 450 bacteria present.
N = 450
According to question,

Hence, Second option is correct.
Answer:
D.The function is decreasing for all real values of x where x < 1.5
Step-by-step explanation:
The vertex is at x=1.5, so the function is decreasing on one side of that and increasing on the other. Any answer choice with some number other than 1.5 as the boundary of increasing/decreasing can be ignored.
Of course one descriptor (<em>increasing</em> or <em>decreasing</em>) is not applicable for any interval that includes the point where the slope changes sign.
The function is decreasing for all real values of x where x < 1.5.

<h3>What is the area of a rectangle?</h3>
Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

Here, (a)is the length of rectangle and (b) is the width of the rectangle
A drawing of the top of a desk is shown.
The image of drawing ins not given in the problem. Here, the length of the desk is 5 feet and the width of the desk is 2 feet according to the data.

Put the values in the above written formula as,

Thus, the area of the top of a desk which is shown and the dimensions of the top is 5 feet and 2 feet, is 10 squared feet.

Answer:
D if car's length is 180 and not 108
Step-by-step explanation:
Truck is 75% longer than the car implies that the length of the truck is 175% (100+75 = 175) of the length of the car.
175/100 × 108
= 189 inches
None of the above
If we take the car's length to be 180 inches, then
175/100 × 180 = 315 inches
