The pattern is 2, 4, 16, 256...
From the pattern, we can see that the next term is square of the previous i.e.
[tex]\Rightarrow 4=2^2\\\Rightarrow 16=4^2\\\Rightarrow 256=16^2[/tex][tex]\Rightarrow 4=2^2\\\Rightarrow 16=4^2\\\Rightarrow 256=16^2[/tex]
So, for the [tex]n^{th}[/tex] term, the function is [tex]f(n)[/tex]
For the next term, it is [tex]f(n+1)[/tex]
So,
[tex]\Rightarrow f(n+1)=[f(n)]^2[/tex]

Answer:
a) at t=12, Whitney is speeding up
b) 13/48 = 0.2704833 . . . miles/min; not a good measure
Step-by-step explanation:
a) At t=12, Whitney's velocity is -0.2 miles/min and is decreasing. That is, the magnitude of her velocity (speed) is increasing. Whitney is speeding up at t=12.
__
b) The (signed) area under the curve, divided by the time period (24 min) will give Whitney's average velocity. It can be found by using the formulas for area of a trapezoid and triangle.
distance 0-11 = 1/2(11 +3)(0.8) = 5.6 miles
distance 11-16 = 1/2(5)(-0.6) = -1.5 miles
distance 16-24 = 1/2(8)(0.6 = 2.4 miles
Whitney's average velocity is ...
(5.6 -1.5 +2.4)mi/(24 min) = 6.5 mi/(24 min) = (13/48) mi/min ≈ 0.270 mi/min
The laws of physics tell us that no work is being done if velocity is constant. Hence, the strenuousness of Whitney's pedaling depends on the acceleration she is maintaining. The average velocity measure tells nothing of that, so is a poor measure of how strenuously Whitney is pedaling.

What is the area of the shape?
40 square centimeters
76 square centimeters
100 square centimeters
224 square centimeters
Answer:
76 sq. centimeters.
Step-by-step explanation:
Answer:
76 square centimeters
Step-by-step explanation:
Break it down into easier shapes.
There is one rectangle and one square. Both of them share the same formula for calculating area: length × width.
The rectangle is 6 cm long and 10 cm wide.
Plug this into the formula:
6 cm × 10 cm = 60 cm^2
The square is 4 cm wide. It does not directly say how long it is. Instead, notice how the rectangle below it is 6 cm long and adding the square to it totals to 10 cm long. This means the square is the difference between the total amount of cm and the rectangle's cm. Calculate the difference:
10 cm - 6 cm = 4 cm.
The square is 4 cm long and 4 cm wide.
Plug this into the formula:
4 cm × 4 cm = 16 cm^2
Add both areas together:
60 cm^2 + 16 cm^2 = 76 cm^2

Suppose that a researcher is interested in estimating the mean systolic blood pressure,u, of executives of major corporations. He plans to use the blood pressures of a random sample of executives of major corporations to estimate u. Assuming that the standard deviation of the population of systolic blood pressures of executives of major corporations is 25 mm Hg, what is the minimum sample size needed for the researcher to be 90% confident that his estimate is within 5 mm Hg of u?
Answer:
The minimum sample size needed is 68.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.9}{2} = 0.05[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.645.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
Assuming that the standard deviation of the population of systolic blood pressures of executives of major corporations is 25 mm Hg.
This means that [tex]\sigma = 25[/tex]
What is the minimum sample size needed for the researcher to be 90% confident that his estimate is within 5 mm Hg of u?
This minimum sample size is n.
n is found when M = 5. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]5 = 1.645\frac{25}{\sqrt{n}}[/tex]
[tex]5\sqrt{n} = 1.645*25[/tex]
Dividing both sides by 5
[tex]\sqrt{n} = 1.645*5[/tex]
[tex](\sqrt{n})^2 = (1.645*5)^2[/tex]
[tex]n = 67.65[/tex]
Rounding up:
The minimum sample size needed is 68.

find the number of bacteria after 10 minutes?
Answer:
Number of bacteria when t = 10 min is 3,000
Step-by-step explanation:
Given:
Number of bacteria in a culture by equation
Q(t) = 2(729^t)
Value of t = 10 min = 10 / 60 = 0.1667 hour
where t is number of hours
Find:
Number of bacteria when t = 0.1667 hour
Computation:
Given equation
Q(t) = 2(729^t)
Put t = 0.1667
Q(10) = 2(729⁰'¹⁶⁶⁷)
We know that;
a⁰ = 1
So,
Q(0.1667) = 2(729⁰)
Q(0.1667) = 3
Number of bacteria when t = 0 is 3,000

A store charges $12.50 for 5 boxes of cookies. A second store charges $8.00 for 4 boxes of cookies, but you have to buy a gallon of milk for $3.00 to get that deal. Write the cost model equations for both stores, and find the number of boxes of cookies that makes the cost equal?
Answer:
20
Step-by-step explanation:
12.50-8.00=3.00
The number of boxes of cookies that makes the cost equal is 6.
What is an Equation?An equation is a mathematical statement containing two expressions on either sides which are connected with an equal to sign.
For the first store,
Cost for 5 boxes of cookies = $12.50
Cost for 1 box of cookie = 12.50 / 5 = $2.50
Cost for x box of cookies = 2.50x
For the second store,
Cost for 4 boxes of cookies = $8
Cost for 1 box of cookie = $8 / 4 = $2
Cost for x box of cookies = 2x
But you have to buy a gallon of milk for $3.00 to get that deal.
Total cost for x boxes of cookies = 2x + 3
Hence the cost model equations are :
C(x) = 2.50x and C(x) = 2x + 3
Cost will be equal when,
2.5x = 2x + 3
0.5x = 3
x = 6
Hence 6 boxes of cookies make both cost equal.

Answer:
Step-by-step explanation:
Suppose that f(2) = −4, g(2) = 3, f '(2) = −5, and g'(2) = 1.
Find h'(2).
(a) h(x) = 4f(x) − 5g(x)
Use the constant multiple and difference rules:
h'(x) = 4f '(x) − 5g'(x)
h'(2) = 4*f'(2) − 5*g'(2), now substitute values and solve
h'(2) = 4*(−5) − 5*1 = −20 − 5 = −25

Step-by-step explanation:
Instead of starting with adjacent letters in the list, we start with the same letter. There are 15 possible pairs.
KK KL KM KN KP LL LM LN LP MM MN MP NN NP PP
__
Additional comment
We leave out pairs with letters previous, because you've said KL is the same as LK, and KL has already been listed. The problem with this list is that it misstates the probabilities of randomly obtaining a given pair. It is not 1/15, but is 2/25 for all but letter duplicates. For duplicates (KK), the probability is 1/25, not 1/15.

Answer:
Part A) The distance between Whitney's house and Anh's house is 6.5 miles.
Part B) The total distance traveled by Whitney during the trip was 9.5 miles.
Step-by-step explanation:
Part A)
Notice that during Whitney's journey to Anh's house, her velocity was negative for some time. So, Whitney was travelling backwards. Hence, the total distance Whitney traveled will be greater than the actual distance from Whitney's house to Anh's.
So, instead, we can calculate Whitney's total displacement. Total displacement is given by:
[tex]\displaystyle \text{Displacement}=\int_a^bv(t)\, dt[/tex]
Where v(t) is the velocity function.
So, the displacement of Whitney when she traveled from her house to Anh's house will be:
[tex]\displaystyle \text{Displacement}=\int_0^{24}v(t)\, dt[/tex]
To calculate the integral, we can split it off at t = 11, t = 16, and t = 24.
The three regions represent three geometric figures, which we can use to calculate the area and then find the integral. Rewriting:
[tex]\displaystyle \text{Displacement}=\int_0^{11}v(t)\, dt+\int_{11}^{16}v(t)\, dt+\int_{16}^{24}v(t)\, dt[/tex]
Now, we can calculate the area of each figure.
The first figure is a trapezoid with a height of 0.8 and two bases of 11 and 3. So, its area is:
[tex]\displaystyle A_1=\frac{1}{2}(0.8)(11+3)=5.6\text{ miles}[/tex]
The second figure is a triangle with a height of 0.6 and a base of 5. So, its area is:
[tex]\displaystyle A_2=\frac{1}{2}(0.6)(5)=1.5\text{ miles}[/tex]
Lastly, the third figure is another triangle will a height of 0.6 and a base of 8. So, its area is:
[tex]\displaystyle A_3=\frac{1}{2}(0.6)(8)=2.4\text{ miles}[/tex]
However, notice that the second figure is below the x-axis. During that interval, Whitney was traveling backwards. Hence, we will subtract the second area from the rest of the areas.
Then the displacement will be:
[tex]\displaystyle \text{Displacement}=5.6-1.5+2.4=6.5\text{ miles}[/tex]
So, the distance between Whitney's house and Anh's house is 6.5 miles.
Part B)
The total distance differs from displacement in that it includes all the distances in both directions. It is given by:
[tex]\displaystyle \text{Distance}=\int_a^b|v(t)|\, dt[/tex]
In other words, all of our values are now positive. We will utilize the same strategy:
[tex]\displaystyle \text{Distance}=\int_0^{11}|v(t)|\, dt+\int_{11}^{16}|v(t)|\, dt+\int_{16}^{24}|v(t)|\, dt[/tex]
Substitute. The only difference is that we will add 1.5 instead of subtracting it. So:
[tex]\displaystyle \text{Distance} =5.6+1.5+2.4=9.5[/tex]
Therefore, in this instance, Whitney traveled a total of 9.5 miles to get to Anh's house.
