Answer:
Yes, 4 + -4 = 0.
Think of it like a number line: The number four is 4 units to the right of the center which is 0, and the number negative four is 4 units to the left of the center. When you add them together, those distances cancel out, and you just get 0.
The series converges, and its sum is 1/2.
If r > 1, the series is divergent. If r < 1, the series is convergent. In our sequence, r, the common ratio we multiply by to get the next term, is 7/9; therefore it is convergent.
To find the sum of a convergent series, we use the formula
a/(1-r), where a is the first term and r is the common ratio. We then have
1/9÷(1-7/9) = 1/9÷2/9 = 1/9×9/2 = 1/2
The inequality is x<25, when Jon cam do less than 25 sit-ups on an exercise ball.
Given that,
Jon can do less than 25 sit-ups on an exercise ball.
We have to find an inequity to illustrate the circumstance.
Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
The inequality is
Take the exercise balls as x
x<25
Therefore, the inequality is x<25, when Jon cam do less than 25 sit-ups on an exercise ball.
