Answer:
The range is f(x) ≥ 0
Step-by-step explanation:
The range of the function is defined as the set of values of the dependent variable for which the function is defined.
Here the function f(x) = 1/2 √x is defined for all values of x which are greater than or equal to zero or we can say all non-negative real numbers.
So, the range is f(x) ≥ 0
Year 1990, dolphins were 243,000
2.3% of 24300
= ( 2.3 / 100 ) * 243000
= ( 0.023 ) * 243000
= 5589
So every year, the population of dolphins decrease by 5589.
Now from 1990 to 2030 will be
= 2030 - 1990
= 40 years
Therefore, for a year = 5589 decrease
For forty years, it will be
= 40 * (5589)
= 223560 dolphins will be lost after forty years
The remaining ones
= 243000 - 223560
= 19440 dolphins will be left
40n (Put up the full time employees hours)
+ 20 (Add the part time employees hours)
> = 260 (> = means greater than or equal to so we use this sign)
Full inequality is 40n + 20 > = 260
Answer:
5
Step-by-step explanation:
3² + 4² = 25
√25 = 5
use the formula
Answer:
By scoring 240 in the sixth game, Marlon can maintain this exact average
Step-by-step explanation:
The first thing to do here is to calculate the average for the first 5 games.
Mathematically, the average can be calculated by adding all the scores in the games and dividing by 5;
= (210 + 225 + 254 + 231 + 280)/5 = 1200/5 = 240
Now to maintain this average score of 240, we want to know the score she must have in the 6th game.
Let the score be x;
By adding x to the previous total of 1200 before and dividing by the new count of 6, we can work our way to get x.
Mathematically, what we are saying is;
(1200 + x)/6 = 240
6 * 240 = 1200 + x
1440 = 1200 + x
x = 1440 -1200
x = 240
