Answer:

y = -13.75x + 340

In 2019, there were 120 owls.

Step-by-step explanation:

To predict the population in subsequent years, utilize the formula y=mx+b due to the linear nature of the change.

Over four years, the fluctuation in the owl population from 340 to 285 is -55. Dividing this by 4 gives a yearly change rate of -13.75, which represents m.

The initial value or y-intercept, denoted as b in the formula, is 340.

Thus, the equation formed is y=-13.75x+340.

For the year 2019, where t=16, we calculate y=-13.75(16)+340, yielding 120.

zzz [9080]

Answer:

Aproximadamente 428 N

Step-by-step explanation:

Peso = 1,500 * 9.8 = 14,700 N

Densidad = Masa ÷ Volumen

1,030 = 1,500 ÷ V

V = 1,500 ÷ 1,030 = 1.46 m^3.

La fuerza de flotación = Densidad * g * V

La fuerza de flotación = 1,000 * 9.8 * (1,500 ÷ 1,030)

La fuerza de flotación = 9,800 * (1,500 ÷ 1,030) = 14,272 N.

La fuerza neta = 14,700 – [(9,800 * (1,500 ÷ 1,030)]

The basketball team scored 82 points from 2- points anf 3-points baskets. They make 38 baskets altogether. Let a represent the n
Zina [9171]

Answer:

The linear equations are:

2a+3b = 82

a+b=38

Step-by-step breakdown:

Here, a denotes the quantity of 2-point shots, and b indicates the number of 3-point shots.

According to the information given:

The basketball team accumulated 82 points through 2-point and 3-point baskets.

⇒ 2a+3b = 82

It is also stated that: They made a total of 38 baskets.

⇒a+b=38

therefore, the linear equations are:

2a+3b = 82

a+b=38
