Answer:
We conclude that the range of the function is 'all positive real numbers'.
Thus, option (A) is true.
Step-by-step explanation:
Given the expression
Determining the domain:
The domain of a function is the set of input values for which the function is real and defined.
It is clear that the given function has no undefined points nor domain constraints.
Therefore, the domain is: -∞ < x < ∞
Thus,
Determining the range:
The range is the set of values of the dependent variable for which a function is defined.
We know that the range of an exponential function of the form
In other words, the range is all positive real numbers.
Thus,
Therefore, we conclude that the range of the function is 'all positive real numbers'.
Thus, option (A) is true.
Answer:
50 · (2 x 10^6) = 1 × 10^8
Step-by-step explanation:
In scientific notation a large number is converted to an equivalent decimal number between 1 and 10, multiplied by 10 raised to some power. Very small numbers are converted to an equivalent decimal number between 1 and 10, multiplied by 10 raised to some negative power.
Answer:
(x - 4)^2 + (y - 1)^2 = 2^2 = 4
Step-by-step explanation:
The applicable equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2. Here, h = 4; k = 1; and r = 2.
So the desired equation is (x - 4)^2 + (y - 1)^2 = 2^2
Answer:
The answer would be that there are more bananas than pears
Step-by-step explanation:
Well, if we were to put the fractions into decimal form 1/8 would be .125 and if we put 1/2 into decimal it would be 0.5 or in this case .500
And since .500>.125 that shows that there are more bananas than pears in the bag, and the other 3/8 are peaches.
First list them in ascending order:-
21, 45, 121, 300, 312, 333, 347, 421, 614
The median is the middle number. In this case as there are 9 numbers the median is the fifth number
Its 312
