Answer:

plz give me BRAINLIEST answer

Step-by-step explanation:

For this case we observe that the time varies linearly with the obtained qualification.

The equation of the line can be obtained as follows

g-go = m (t-to)

where (go, to) are points that belong to the line.

To form the equation you need two points. These points are

(g1, t1) = (0,0)

(g2, t2) = (6.5.84)

Then, substituting, the equation of the line is

m = (84-0) / (6.5-0) = 84 / 6.5 = 12.923

g-0 = (12,923) * (t-0)

Rewriting.

g = 12.923t

The slope of the line is

m = 12,923

Answer:

After 2009 the quality of the forests in this country improving.

Step-by-step explanation:

Consider the provided function.

f(t) = \frac{1}{3}t^3-\frac{5}{2}t^2 + 80

f'(t) = t^2-5t

Substitute f'(t)=0.

t^2-5t=0

t(t-5)=0

t=0\ or\ t=5

It is given that  (0 ≤ t ≤ 10)

The test interval are (0,5) and (5,10)

For (0 < t < 5) the value of f'(t)

For (5 < t < 10) the value of f'(t) >0

Hence, the function is increasing from (5,10).

t = 0 corresponds to 2004.

Therefore, after 2009 the quality of the forests in this country improving.

Answer:

<u>$15 per hour</u>

Step-by-step explanation:

Since he charged $65 for the parts, and the total charge was $110, that's $110-$65 which is $45, the total hours was 3, so $45 divided by 3, and that equals $15.
