Step-by-step explanation:
<u>Surface Areas
</u>
Is the sum of all the lateral areas of a given solid. We need to compute the total surface area of the given prism. It has 5 sides, two of them are equal (top and bottom areas) and the rest are rectangles.
Computing the top and bottom areas. They form a right triangle whose legs are 4.5 mm and 6 mm. The area of both triangles is
The front area is a rectangle of dimensions 7.7 mm and 9 mm, thus
The back left area is another rectangle of 4.5 mm by 9 mm
Finally, the back right area is a rectangle of 6 mm by 9 mm
Thus, the total surface area of the prism is
Answer:
not a function. domain = -2, 3, 8 (you don't have to write them in any specific order and you also don't need to write -2 twice)
Step-by-step explanation:
to be a function, all of the x's must be different
(x + 2) = 3
-2 -2
0 1
x = 1
Answer: The answer is (c) 
Step-by-step explanation: Given that there are two functions f and g, defined by
We are to find f*g and also its domain.
Also, its domain will be all real numbers, since the function f*g is defined at all 'x' in real numbers.
Thus, the correct option is
Answer:
Step-by-step explanation:
Suppose that at time 
we have x mold cells. We are told that after 12 minutes the amount present is double. That is a 
we have 2x cells. Then, at 
we have (2x)*2 = 4x. We can continue as follows
we have (4x)*2 = 8x.
we have (8x)*2 = 16x
(one hour later) we have (16x)*2 = 32x.
So after one hour from now we have 32x cells.
