Sam painted 3 pictures.ellie painted twice as many pictures as Sam how many pictures did they paint altogether

To respond to this inquiry, we must assume that Eva works for 8 hours each day. If that's the case, then on the first day, Eva will complete jobs w, x, and v, amounting to six hours of work. Since job y takes 4 hours, she will only have 2 hours of work that day, leaving her with 2 hours remaining to continue on job y. The following day, she will use those 2 hours to finish job y, completing it, and also work on job z (which takes hours). Consequently, she will have tackled 4 jobs on the first day and 2 jobs on the second, resulting in an average of 3 jobs each day.
This assumption is based on an 8-hour workday and indicates that Eva can initiate jobs she can't finish within the same day.

The sine function that corresponds to the scenario is y = 6sin((π / 10) x) - 10.

Step-by-step explanation:

The general equation for a sine function is Asin(Bx)+C.

A buoy rises and drops 6 meters, indicating a vertical and horizontal movement of 6 meters—this is the amplitude.

Thus, the amplitude A is 6.

The period is defined as the horizontal distance for one complete wave cycle.

The buoy takes 10 seconds to go from its peak to its lowest point (half a cycle).

Hence, the total period for a complete cycle is 20 seconds.

Additionally, Period = 2π divided by B.

Thus, 20 (B) = 2π.

This results in B being equal to 2π / 20.

= π / 10.

Since the buoy operates at a depth of 10 meters, C equals -10.

⇒y = 6sin((π/10)x) - 10.

The first point marks the midline,

When x=0,

⇒y=6sin(0)-10.

y= -10.

∴ Thus, the line begins at y = -10.

The consecutive point will represent the maximum or minimum value.

Those are (5,-4) and (15, -16.)

The diver descends, resulting in a movement downwards of −20 feet. Begin with 20 negative tiles and divide them into 5 equal sets. Each set contains 4 negative tiles, indicating he descended at a speed of −4 feet per second.
