Find the 66th term in the following
arithmetic sequence :
--92, -85, -78, -71, ...
Answer:
363
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 92 and d = - 85 - (- 92) = - 85 + 92 = 7 , thus
[tex]a_{66}[/tex] = - 92 + (65 × 7) = - 92 + 455 = 363
Answer:
363.
Step-by-step explanation:
We see that each term increases by 7.
This is an arithmetic sequence with first term (a1) = -92 and the common difference (d) is 7.
an = a1 + (n - 1)d
a66 = -92 + (66 - 1)7
= -92 + 455
= 363.

The product of the given numbers is 1.61 × 10⁸.
What is meant by Scientific Notation?Scientific notation is a way of writing a large number or small number with many digits in a simpler form using the power of 10.
For example, 30,000 can be written as 3 × 10⁴.
Given that,
We have to multiply the numbers (2.3 x 10¹) (7 x 10⁶).
The numbers in scientific notation uses exponents.
So we have to use the product rule of exponents here.
(2.3 x 10¹) (7 x 10⁶) = (2.3 × 7) × (10¹ x 10⁶)
= 16.1 × (10¹ x 10⁶)
We have the product rule, xᵃ . xᵇ = xᵃ⁺ᵇ
So the product is,
(2.3 x 10¹) (7 x 10⁶) = 16.1 × (10¹⁺⁶)
= 16.1 × 10⁷
= 1.61 × 10⁸
Hence the product in scientific notation is 1.61 × 10⁸.

help me fill in the blanks pleasee
Answers and Step-by-step explanations:
Let's look at the first row:
cost = _______ + _______ * (monthly payment)
The first blank should be the "down payment" because this is the initial, constant value that is paid. The second blank should be the "number of months" because this way, when multiplied by the actual amount each payment is (monthly payment), then we get the total amount paid during those months.
So, we have:
cost = (down payment) + (number of months) * (monthly payment)
Now for the second row, we just plug in numbers and variables:
335 = 50 + 6 * p
Finally, we can solve for p:
335 = 50 + 6p
6p = 285
p = $47.50
Answer:
Cost = down payment + no. of monthly payments × monthly payment
335 = 50 + 6 × p
285 = 6p
p = 47.5

what is 10 1/3 x 1/4? that is, what is ten and one third times one fourth?
Answer: 31/12, or 2 7/12
Step-by-step explanation: The answer is actually very simple. All you have to do is to simplify 10 1/3 into 31/3, as 10x3+1=31. Then, you have to multiply 31/3 with 1/4. Do a simple fraction multiplication, and you get 31/12, or 2 7/12 if your teacher is asking for a mixed number. Sometimes simplifying is better

The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
To find the length of side XZ, we can use the distance formula, which is:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Substituting the coordinates of X (-2, 4) and Z (3, 4), we get:
[tex]d(XZ) = \sqrt{(3 - (-2))^2 + (4 - 4)^2}\\= \sqrt{5^2 + 0^2}\\= \sqrt{25}\\= 5[/tex]
The length of side XZ is 5 units.
To find the length of side YZ, we can again use the distance formula with the coordinates of Y (3, -2) and Z (3, 4):
[tex]d(YZ) = \sqrt{(3 - 3)^2 + (4 - (-2))^2}\\= \sqrt{0^2 + 6^2}\\= \sqrt(36)\\= 6[/tex]
The length of side YZ is 6 units.
Thus,
The length of side XZ is 5 units.
The length of side YZ is 6 units.

The rule T5, -0.5 oR 0, 180(x,y) is applied to triangle FGH to produce triangle F’G’H’. What are the coordinates of vertex F’ of triangle F’G’H’?
Answer:
Step-by-step explanation:
Rule for the transformations has been given as,
[tex]T_{(5, -0.05)o\text{R}(0, 180)}(x,y)[/tex] defines the rules as the translation by 5 units right and 0.5 units down followed by rotation of the triangle by 180° about the origin.
In other words,
Rule for translation:
F(x, y) → F"(x + 5, y - 0.5)
Followed by the rotation of 180° about the origin,
Rule of rotation,
F"(x', y') → F'(-x, -y)
Following these rules coordinates of the new triangle F'G'H' can be obtained.

Write a problem that could be modeled with y=200(0.9).
First, I need to decide what equation this is like.
I believe this is y=mx.
We know that x is typically the input, and m is the constant function.
Y is the output.
So the original function may have been y=200x.
The only difference is now we've been given something to apply to the equation, in place of x.
2. Imagine a cloning machine. Whatever you put in, you get a copy of, and the original thing you put in. Its function would be y=2x. Let's pretend we decided to put three things in; 3 would go where x is.
Y would be the result of 3 copies and their originals, or 2(3).
(6=2(3))
Now, when someone else decides to use the cloning machine, they may put any number in, but the only properties that will change are y and x, not m.
The function will remain y = 2x. Any number could go in place of x, and multiplying x by 2 will give you the y. As long as you have a different value for x, the y will never be the same.
3. So now we have an understanding of what it means, we see that we have been given an x value to insert; an input.
A more practical example could be someting with money. This won't be entirely realistic, because we are dealing with a fraction of a number and another large number.
4. I decided to go with flour. I wanted the 200 to represent pennies, or cents. Before I landed on this, I looked up the cost of flour per pound. I found that the average is .43 dollars, which isn't terribly close to two dollars. But maybe the flour is high quality, so we can stick with that.
5. Seeing that this equation, y=200x, means we are charging 200 cents, or two dollars, we can write a problem from here.
Sylvia is in charge of selling home-harvested flour from an organic farm. She charges two dollars per pound of flower. Today, her next-door neighbors hope to buy a ninth of pound of flour, and they insist on paying with pennies. How many pennies do they need to pay for their order?
