The x-intercepts of f(x) = sin (x + π/4) are

1 answer:

3 0

The x-intercepts of a function is determined by replacing y or f(x) to zero since this is the point of x where it crosses the x-axis (y=0). In this case, for f(x)= sin (x + π/4) , we substitute 0 = sin (x + π/4). sin^-1 of zero is also zero and pi. hence

x + π/4 = 0
x = -π/4

x + π/4 = π
x = 3π/4

Seven men make 21 toys in 30 minutes. How long would it take 21 men?

konstantin123 [22]

Answer:

10 minutes

Step-by-step explanation:

Assuming men and minutes are interchangeable, 3 times as many men can be assumed to assemble the toys in 1/3 as much time.

21 men can make 21 toys in 30/3 = 10 minutes.

_____

Additional comment

We have to assume there are no rate-limiting steps in the process. This assumption is not always valid.

I NEED THIS FAST! I WILL PUT BRAINIEST IF IT IS CORRECT A group of workers is harvesting berries at a constant rate. An equation

Strike441 [17]

A) the slope of the equation is 5, the y intercept is 10.
b) the rate of change is just the slope, so 5 but it means that they are picking 5 berries over that period of time. the initial amount is just the y intercept which is 10. this is just how many berries you start with.
c)
