A population of rabbits in a lab, r(x), can be modeled by the function r(x) = 30(1.02)^x, where x represents the number of days since the population was first counted. Determine, to the nearest tenth, the average rate of change from day 35 to 52, including units
Answer:
The population of the rabbits in the lab grew, on average, at a rate of 1.4 rabbits per day from day 35 to 52.
Step-by-step explanation:
The average rate of change of a function between two points is essentially the slope between them.
We have the function:
[tex]r(x)=30(1.02)^x[/tex]
And we want to find the average rate of change from x = 35 to x = 52.
We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Our first point will be (35, r(35)) and our second point is (52, r(52)). Substitute:
[tex]\displaystyle m=\frac{r(52)-r(35)}{52-35}[/tex]
Note that our outputs y are rabbits and our inputs or x are days. Substitute:
[tex]\displaystyle m=\frac{30(1.02)^{52}-30(1.02)^{35} \text{ rabbits}}{52-35\text{ days}}[/tex]
Use a calculator:
[tex]\displaystyle m\approx\frac{1.4\text{ rabbits}}{\text{day}}[/tex]
So, the population of the rabbits in the lab grew on average at a rate of 1.4 rabbits per day from day 35 to 52.

In one minute adrians fan oscillates 12 times if the fan is on for 8 minutes how many time will it oscillate
Answer: 96 oscillations
Step-by-step explanation:
The fan oscillates at a rate of 12 times per minute.
This means that for every minute that goes by, the fan would have oscillated 12 times.
If the fan is on for 8 minutes, the number of oscillations is:
= Oscillations per minute * number of minutes
= 12 * 8
= 96 oscillations

Answer:
H=3m
Step-by-step explanation:
Volume of cylinder=pir^2h
75pi=pi5^2h
75/25=h
h=3
Answer:
The height is 3 m.
Step-by-step explanation:
The formula for the volume of a cylinder is V=πr^2h, where V is the volume, r is the radius and h is the height.
We are given r, the radius, and the volume, so all we need to do is plug it into the formula and solve for h, our height.
V=πr^2h
Substitute V for 75π and r for 5
75π=π5^2h
Square 5
75π=25πh
Divide by 25π on both sides
3=h
3 m is the height.

The sun and the earth's interiorStep-by-step explanation:
As,
The Earth has two basic sources of energy -
Earth's Interior- hat reaching the Earth from the Sun (Solar Energy) and that reaching the surface of the Earth the Earth itself (Internal or Geothermal Energy). Solar Energy - reaches the Earth in the form of radiant energy, and makes up 99.987% of the energy received by the Earth.Using the Exxon data as an example pretend Pennys Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares what percent of Penny's Picklesdo you own
Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have [tex]2\[/tex] percent of Penny's Pickles.
What is percentage?Percentage a is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, [tex]\%[/tex].
Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]
We have,
Total shares of Penny's Pickles [tex]=10,000[/tex]
You owned shares [tex]= 200[/tex]
So,
Using above formula,
Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]
Percentage of shares I owned [tex]=\frac{200}{10000} * 100[/tex]
[tex]= 2 \%[/tex]
So, the shares you owned are [tex]2\ \%[/tex] of total share of the Penny's Pickles.
Hence, we can say that Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have [tex]2\[/tex] percent of Penny's Pickles.

The length of a rectangle is 5 inches more than its width. The area of the rectangle
is 150 centimeters. Find the dimensions of the rectangle.
it's good to write it out
length = 5 + width
area = 150
width = x
length = 5 + x
area = length * width
so
(5 + x) (x) = 150
5x + x^2 = 150
x^2 + 5x - 150 = 0
following you have to guess what 2 numbers when multiplied male 150 and when added make 5
and they are 15 and 10
(x +15) (x-10)
x = -15
x = 10
so the dimensions are
length = 15
and
width = 10
Jessie has rewritten the quadratic equation x2-32x +54 -0 in the form (-p) = 202. What is the value of p in the rewritten equation?
Given:
The quadratic equation is:
[tex]x^2-32x+54=0[/tex]
It can be written as [tex]-p=202[/tex].
To find:
The value of p in the rewritten equation.
Solution:
We have,
[tex]x^2-32x+54=0[/tex]
Isolate the constant term.
We need to make 202 on the right side. So, add 256 on both sides.
[tex]x^2-32x+256=-54+256[/tex]
[tex]x^2-32x+256=202[/tex]
[tex]-(-x^2+32x-256)=202[/tex]
Let [tex]-x^2+32x-256=p[/tex], then
[tex]-p=202[/tex]
Therefore, the value of p is [tex]-x^2+32x-256[/tex].
The given equation can be written as:
[tex]54=-x^2+32x[/tex]
Adding 148 on both sides, we get
[tex]54+148=-x^2+32x+148[/tex]
[tex]202=-(x^2-32x-148)[/tex]
Let [tex]x^2-32x-148=p[/tex], then
[tex]202=-p[/tex]
Therefore, the another possible value of p is [tex]x^2-32x-148[/tex].

The length of a rectangle is 3 inches more than its width. The perimeter of the rectangle is 34 inches.
length = 3 + width
perimeter = 34
34 ÷ 2 = 17
width = x
3 +x + x = 17
3 + 2x = 17
2x = 14
x = 7

Drew has two cats. One cat weighs 17 pounds, and the other one weighs 1212 pounds. Audrey’s dog weighs 33 pounds.
What is the difference in ounces between Audrey’s dog and the combined weights of Drew’s cats?
Enter your answer in the box.
Answer:
48 ounces
Step-by-step explanation:
Answer:
64 ounces.
Step-by-step explanation:
combined weigh = weight of cat 1 + weight of cat 2
combined weigh = 17 + 12 = 29 pounds
The difference in weight of the Dog's weigh by the combined cat's weigh is the subtraction between the two, so we have:
Difference in weigh = 33 - 29 = 4 pounds
We now have to convert it to ounces, since 1 pound contains 16 ounces we can multiply the value of the weigh in pounds by 16 to obtain the final value:
Difference in weigh = (4 pounds)* 16 = 64 ounces
