A population of rabbits at time t increases at a rate of 40-12t+3t^2 rabbits per year where t is measured in years. Find the population after eight years if there are 10 rabbits at t=0?
We have to find derivative of t

[tex]\boxed{\sf \dfrac{d(x^n)}{dx}=nx^{n-1}}[/tex]

Suppose M is the midpoint of FG. Use the given information to find the missing measure or value.
FM =5y + 13, MG = 5 - 3y, FG = ?
Answer:
FG = 16
Step-by-step explanation:
F___M___G
FG = FM+MG
FG = ( 5y +13 ) + (5-3y)
FG = 2y + 18
FM = MG
5y +13 = 5-3y
5y +3y = 5 - 13
8y = - 8
y = -8/8
y = – 1
FG = 2y + 18 = 2(-1) + 18 = – 2 + 18 = 16

A certain stock's price, S (t), can be modeled by the polynomial function S (t) = t^4 – 12t^3 + 52t^2 – 96t + 64, where t represents the month in 2021. In which month will the price of the stock have a local maximum?
February
March
April
May
Answer:
April
Step-by-step explanation:
To solve, you find the maximum of the polynomial function. You can do this by either graphing or plugging in the values in a T chart.
I graphed the function, provided down below.
As you can see, the highest value in the graph is the middle most point, aka (4,1). Count down the months of the year to 4, and you'll find that April is the 4th month of the year.
Using derivative concepts, it is found that the function has a local maximum in March.
--------------------
A function S(t) has local maximums or minimums at points in which the derivative is 0.If the function goes from increasing(positive derivative) to decreasing(negative derivative), it has a local maximum.The function is:
[tex]S(t) = t^4 - 12t^3 + 52t^2 - 96t + 64[/tex]
Which has the following derivative:
[tex]S^{\prime}(t) = 4t^3 - 36t^2 + 104t - 96[/tex]
Now, for each month, it has to be tested the derivative, verifying if it's zero.--------------------
February is the 2nd month, thus, the derivative is:
[tex]S^{\prime}(2) = 4(2)^3 - 36(2)^2 + 104(2) - 96 = 0[/tex]
Now, we have to test a value less than 2, and one greater than two, to check if it goes from increasing to decreasing, that is, derivative goes from positive to negative.
[tex]S^{\prime}(1.5) = 4(1.5)^3 - 36(1.5)^2 + 104(1.5) - 96 = -7.5[/tex]
[tex]S^{\prime}(2.5) = 4(2.5)^3 - 36(2.5)^2 + 104(2.5) - 96 = 1.5[/tex]
From negative to positive, thus, a local minimum in February.
--------------------
March is the 3rd month, thus, the derivative is:
[tex]S^{\prime}(3) = 4(3)^3 - 36(3)^2 + 104(3) - 96 = 0[/tex]
Testing before and after:
[tex]S^{\prime}(2.5) = 4(2.5)^3 - 36(2.5)^2 + 104(2.5) - 96 = 1.5[/tex]
[tex]S^{\prime}(3.5) = 4(3.5)^3 - 36(3.5)^2 + 104(3.5) - 96 = -1.5[/tex]
From positive to negative, thus, it has a local maximum in March.

4. A model of the Elffel Tower that was
purchased in a gift shop is 30 -
inches tall. The actual height of the
Elffel Tower is 1000 feet, or 12,000
inches. What scale factor was used to
make the model?
Answer:
400
Step-by-step explanation:
To find the scale factor, you need to find out how much the initial value was multiplied by to get the new value. To do that, you need to divide the new value by the initial value. Make sure the units are the same; don't divide 1000 feet by 30 inches!
[tex]\frac{new}{initial} = \frac{12000}{30}=400[/tex]

Answer:

Step-by-step explanation:
The slope of the line is 0 as it is parallel to x-axis.
Slope = (y2 - y1)/(x2 - x1)
= (2-2)/(4-(-2))
= 0
Answer:
Slope = 0
Step-by-step explanation:
Taking any two points.
(x1,y1) = (3,0)
(x2,y2) = (-1,0)
Now,
[tex]\displaystyle Slope = \frac{y_2-y_1}{x_2-x_1} \\\\Slope = \frac{0-0}{-1-3} \\\\Slope = \frac{0}{-4} \\\\Slope = 0\\\\\rule[225]{225}{2}[/tex]

Answer:
Option CStep-by-step explanation:
The data in the table shows quantity increase with the price increase and we want to analyze the relationship between price and quantity.
The data indicates a positive slope if we keep price on x-axis and quantity on y- axis.
Option C is reflecting this and correctly highlighted.
Answer:
Option C
Step-by-step explanation:
Because as we can see y is increasing with respect to x
So the slope is positive
The line should go up rightwards
Hence option C is correct

A survey of 300 people found that 60 owned an iPhone, 75 owned a Blackberry, and 30 owned an Android phone. Furthermore, 40 owned both an iPhone and a Blackberry, 12 owned both an iPhone and an Android phone, and 8 owned a Blackberry and an Android phone. Finally, 3 owned all three phones. (a) How many people surveyed owned none of the three phones? (b) How many people owned a Blackberry but not an iPhone? (c) How many owned a Blackberry but not an Android?
Step-by-step explanation:
We let A be the set of those who owned an iPhone, B be the set of those who owned a Blackberry,
and C those that owned an Android. Therefore we have |A| = 60, |B| = 75, and |C| = 30. Also,
we know that |A ∩ B| = 40, |A ∩ C| = 12 and |B ∩ C| = 8. Finally, |A ∩ B ∩ C| = 3. Therefore,
by the principle of inclusion/exclusion, we have
|A ∪ B ∪ C| = |A| + |B| + |C| − |A ∩ B| − |A ∩ C| − |B ∩ C| + |A ∩ B ∩ C|
= 60 + 75 + 30 − 40 − 12 − 8 + 4
= 109
(a) Since there are 300 total people, there are 191 without one of the types of phone.
(b) Since |A ∩ B| = 40 and |B| = 75, there are 35 people with a Blackberry that don’t own
an iPhone.
(c) Since |B ∩ C| = 8 and |B| = 75, there are 67 people with a Blackberry that don’t own
an Android.

10. The product of two integers is -18. The difference between the integers is 9. The sum of the
integers are 3. What are the two integers?
Answer:
x = 6
y = - 3
Step-by-step explanation:
x * y = - 18
x - y = 9. 3-y-y = 9. 3 -2y = 9.
-2y = 9-3
y = 6/-2
y = -3
x + y = 3. x = 3-y
x * -3 = - 18
x = -18/-3
x = 6
