F(x) = sin(x^2 - 2) find points of discontinuity, if any ...?

1 answer:

6 0

Function sin(x) is defined for all real numbers.
Function x^2-2 is a parabola which is defined for all real numbers.

Therefore, function f(x) = sin(x^2 - 2) has no <span>points of discontinuity.</span>

Kyle ran 2/3 mi on Monday,1 1/6 mi on Tuesday, and 7/12 mi on Wednesday.

BartSMP [9]

you would change the denominators to the least common multiple, in this case, 12. then you would change the fractions to 8/12, 14/12, and 7/12. you would add those, and get 29/12. divide 29 by 12, and get 2. add the rest to get 2 5/12.

Emily is picking strawberries at a speed of 3 strawberries per second. Her little sister Sophia joins Emily when there are 20 st

Zina [86]

Answer:

6 seconds

Step-by-step explanation:

Using the information from the problem, if Emily continues to pick 3 strawberries per second while Sophia eats 5 strawberries per second, then the amount of strawberries will decrease at a rate of 2 strawberries per second. Therefore, we can find the answer by subtracting 2 from 20 until we get to 8. Since we subtract 2 six times, the answer is 6. Hope this makes sense!

in the usa, the shoe sizes or men are approximated by the equation 3f-s=24, where f represents the length of the foot in inches

Otrada [13]

Answer:

x intercept = 8

y intercept = -24

Step-by-step explanation:

In the USA, the shoe sizes or men are approximated by the equation 3f-s=24, where f represents the length of the foot in inches and s represents the shoe size.

<u>When we represent this equation using a graph, we mark the independent variable on the x axis and the dependent variable on the y axis.</u>

Here the foot length is the independent variable and the shoe size is the dependent variable. Hence we take foot length on x axis.

To get x intercept put y=0, f = $\frac{24}{3}$ = 8 inches .

This is the point from which where we start our shoe size.

The y intercept , s = -24.
