A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the

plant f(n), in cm, after n days:
f(n) = 12(1.03)n

What is the average rate of change of the function f(n) from n = 3 to n = 10, and what does it represent? (4 points)

Answer:

The average of rate was of 0.4314 cm/day, which means that on average, during this interval, the plant grew by 0.4314 cm each day.

Step-by-step explanation:

Average rate of change:

The average rate of change of a function f(x), from x = a to x = b, is given by:

A = \frac{f(b)-f(a)}{b-a}

In this question:

f(x) = 12(1.03)^n

From n = 3 to n = 10

a = 3, b = 10

f(b) = f(10) = 12(1.03)^{10} = 16.13

f(a) = f(3) = 12(1.03)^{3} = 13.11

Average rate of change:

A = \frac{f(b)-f(a)}{b-a} = \frac{16.13-13.11}{10-3} = 0.4314

The average of rate was of 0.4314 cm/day, which means that on average, during this interval, the plant grew by 0.4314 cm each day.

A rectangle has a length of 14 yards less than 9 times its width. If the area of the rectangle is 6183 square yards, find the le
Jlenok [28]

Answer:

 l=238\ yards

Step-by-step explanation:

From the question we are told that:

Area of Rectangle A=6183

Equation of Length

 l=9w-14

Where

w=width\ of\ triangle

Generally the equation for Area of Rectangle is mathematically given by

 A=(9w-14)w

 A=9w^2-14w

 6183=9w^2-14w

 9w^2-14w-6183=0

 w=28

Therefore

 l=9(28)-14

 l=238\ yards

Cosine again. Yay.

Put 36 into a fancy calculator with one of those cos() things. You get about 0.81. 

So that's the ratio between x and 10.

So basically x/10 = 0.81, or 0.81 * 10 = x.

8.1 = x

What is another way to write 0.7?
SVEN [57.7K]
7/10. Because 0.7 equals 70% . As a fraction it would be 70/100. Simplify, and you get 7/10.

The weight of a specific type of male monkey is normally distributed with a mean of 15 pounds and a standard deviation of 3 poun
Viktor [21]

Answer:

1.33

Step-by-step explanation:

The z-score of a value is found by subtracting the mean from the value and then dividing by the standard deviation, this is the formula for the z-score.

z-score = (19-15)/3

z-score = 4/3

z-score = 1.33

The z-score for the monkey is about 1.33
