At an ocean depth of 8 meters, a buoy bobs up and then down 5 meters from the ocean's depth. Sixteen seconds pass from the time

lisov135 [29]

Answer:

See attached for a graph

Step-by-step explanation:

We're going to plot sea level as y=0 and a depth of 8 meters as y=-8.

The problem statement tells you the initial point (x=0) is at normal ocean depth (y=-8), so the first point you put into your sine tool is ...

(x, y) = (0, -8)

The buoy takes 16 seconds to go from a high point to a low point, so the time to the first high point is half that, or x=8 seconds. That high point is 5 meters above its average depth, so is at y=-3.

The second point you will put into your sine tool is ...

(x, y) = (8, -3)

Talja [164]

Answer:

Robbin's grade point average must be at least 2.75 in order to be unconditionally accepted into the program.

Step-by-step explanation:

An unconditional acceptance into a graduate program at a university will be given to students whose GMAT score plus 100 times the undergraduate grade point average is at least 1075

Considering the GMAT score x, and the GPA y, this situation is modeled by the following inequality:

$x + 100y \geq 1075$

Robbin's GMAT score was 800.

This means that $x = 800$ , and thus:

$x + 100y \geq 1075$

$800 + 100y \geq 1075$

$100y \geq 275$

What must her grade point average be in order to be unconditionally accepted into the program?

Solving the above inequality for y:

$100y \geq 275$

$y \geq \frac{275}{100}$

$y \geq 2.75$

Thus:

Robbin's grade point average must be at least 2.75 in order to be unconditionally accepted into the program.

The circle graph shows the results of a survey by a bakery on which of their new products 105 customerspreferred most. How many

Katen [24]

If 105 customers were the total, and 35% prefers cake, we must calculate 35% of 105, then we must do 105 multiplied by 35%, we can doit transforming the 35% in the fraction notation:
