Answer:
(A) 509.78
We need to move the decimal point after the first non-zero digit
So,
=> 5.0978 × 10² (Since the decimal point is moved two places to the left)
(B) 0.0289
Again after the first non-zero digit:
So, it becomes:
=> 2.89 × 10⁻² (Since the decimal point is moved 2 places to the right so it will be negative also)

Answer:
B.
Step-by-step explanation:
A cone with a radius of 1-unit will be obtained by rotating the 3-D figure.
Answer:
A = 1
B = 2
C = below
Step-by-step explanation:
Zero is included in the second interval, therefore, A = 1 is a correct choice (A must be also less than 2 ).
B must be positive, so that, f(0) is above the x-axis, therefore, B = 2 is a correct choice.
f(1.5) is negative, this means that the function is <u>below</u> the x-axis, then, C = below.
