Answer:
An = 6 +8(n -1)
Step-by-step explanation:
The given terms have a first term of 6 and a common difference of 8, so the formula is ...
An = A1 +d(n -1)
An = 6 +8(n -1)

Two angles have a difference of 30 degrees. If the greater angle, a, and the smaller angle, b, are complementary, what is the measure of angle a?
Answer:
A=60
Step-by-step explanation:
Complementary means it's 90 degrees
60 and 30 have a 30 degree difference.
The measure of angle a is 60°
What are Complementary Angles?
When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
Given data ,
The two angles are a and b
a and b are complementary
So , a + b = 90°
The difference of angle a and b is 30°
The greater angle is a and smaller angle is b
So , a - b = 30°
Now , we have two equations
a + b = 90°
a - b = 30°
Adding both equations , we get
2a = 120°
Divide by 2 on both sides , we get
a = 60°
Hence , the measure of angle a is 60°

Suppose that a randomly generated list of numbers from 0 to 9 is being used
to simulate an event that has a probability of success of 20%. Which of these
groups of numbers could represent a success?
Answer:
0, 1
Hope this helps :)
The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To simulate an event that has a probability of success of 20%, we need to randomly generate numbers from 0 to 9 such that there is a 20% chance of getting a "success" number.
Since there are 10 possible numbers to choose from, 20% of them would be 2 "success" numbers.
So, any group of numbers that contains two "success" numbers out of 10 would represent a success.
For example,
The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.
Other groups with two "success" numbers would also be valid.
Thus,
The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.

Answer:
667680
Step-by-step explanation:
6240 times 104 i think
Answer:
He planted 60 tomato plants, or 5 dozen tomato plants.
Step-by-step explanation:
6 dozen = 6 × 12 = 72
He planted 72 plants and harvested 104 tomatoes per plant.
The next year he had a crop of 6,240 tomatoes, and also got 104 tomatoes per plant.
6,240/104 = 60
He planted 60 tomato plants, or 5 dozen tomato plants.

A farmer has collected data from one of his crops. Suppose the farmer found that the number of seeds, () (in weeks) was
()= t^2/4 seeds per mature plant.
Further, the farmer discovered that only
()=40.56−^2/4+1801.75/^2+188.8/
plants matured to age .
Determine the maximum rate of change of the crop's seed production
The rate of change of the crop's seed production is given by differential of
the function of the number of seeds produced.
The maximum rate of change of the seed production is approximately 117 seeds per week.Reasons:
[tex]\displaystyle \mathrm{The \ number \ of \ seeds \ per \ plant, \ S(t)}= \mathbf{\frac{t^2}{4}}[/tex]
[tex]\displaystyle \mathrm{Plants \ that \ mature \ to \ age \ t, \ P(t)}= \mathbf{40.56- \frac{t^2}{4} + \frac{1,801.75}{t^2} +\frac{188.8}{t}}[/tex]
The number of seeds produced by all the plants, n = S(t) × P(t)
Which gives;
[tex]\displaystyle \mathrm{\ P(t) \times S(t)}= \left(40.56- \frac{t^2}{4} + \frac{1,801.75}{t^2} +\frac{188.8}{t}\right) \times \frac{t^2}{4}[/tex]
[tex]\displaystyle \mathrm{ \left(40.56- \frac{t^2}{4} + \frac{1801.75}{t^2} +\frac{188.8}{t}\right) \cdot\frac{t^2}{4}} = \mathbf{-0.0625\cdot t^4+10.14\cdot t^2 + 47.2 \cdot t + 450.4375}[/tex]
The maximum rate of change is the highest value of the rate of change function.
To find the maximum rate of change of the crops production, the above
function for the number of seeds is differentiated twice. The first
differentiation is to find the rate of change function, and the second
differentiation is to determine the value of t at the maximum rate of change
as follows;
The rate of change of the crop's seed production is given by following function;
[tex]\displaystyle \frac{d}{dt} \left( -0.0625\cdot t^4+10.14\cdot t^2 + 47.2 \cdot t + 450.4375 \right) = -0.25\cdot t^3+ 20.28 \cdot t - 47.2[/tex]
Rate of change function, n'(t) = -0.25·t³ + 20.28·t + 47.2
At the maximum value of the above rate of change function, we have
[tex]\displaystyle \frac{d}{dt} \left( -0.25\cdot t^3+ 20.28 \cdot t - 47.2 \right) = \mathbf{-0.75 \cdot t^2 + 20.28} = 0[/tex]
Which gives
[tex]\displaystyle t^2 = \frac{20.28}{0.75} = \mathbf{27.04}[/tex]
t = √27.04 = 5.2
At the maximum rate of change, the number of weeks, t = 5.2
Plugging in the value of t = 5.2 into the rate of change function gives;
n'(5.2) = -0.25·5.2³ + 20.28·5.2 + 47.2 = 117.504
The maximum rate of change of the crop's seed production is approximately 117 seeds per week.Learn more here:
