find the 120th term of the following sequence
7, 14, 21, ...
a120 =
Answer:
840
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 14 - 7 = 21 - 14 = 7
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 7 , thus
[tex]a_{120}[/tex] = 7 + (119 × 7 ) = 7 + 833 = 840

If b is the midpoint of line AC, and AC = 8x-20, find BC.
The Definition Of a Midpoint says that is B is the
midpoint of segment AC, then segment AB ≅ AC.
Since segment AB ≅ segment BC, we can setup
the equation 2(3x - 1) = 8x - 20 and we can solve from here.
Start by distributing the 3 through the parenthses on the left side.
So we get 6x - 2 = 8x - 20.
Now subtract 8x from both sides to get -2x - 2 = -20.
Now add 2 to both sides and we have -2x = -18.
Finally, dividing both sides by -2, we find that x = 9.
If x = 9, segment BC must be 3(9) - 1 or 27 - 1 which is 26.
What is the midpoint of points (1,1) and (-6,-8)
Answer:
(-2.5, -3.5)
Step-by-step explanation:
In order to find midpoint, you must add both x coordinates then divide by two and add both y coordinates then divide by two.
1 + (-6) = -5
-5/2 = -2.5
1 + (-8) = -7
-7/2 = -3.5

I need this TONIGHT!!! Three years ago, Jolene bought $750 worth of stock in a software company. Since then the value of her purchase has been increasing at an average rate of 5 1/2% per year. How much is the stock worth now? (Round each money calculation you make to the nearest cent.) The stock is worth $ now.
Answer:
[tex]A\approx\$880.68[/tex]
Step-by-step explanation:
So, we know that Jolene bought an initial $750.
We also know that the purchase is increasing at an average rate of 5 1/2 %or 5.5%. In other words, this is being compounded.
So, we can use the compound interest formula, which is:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Where A is the total amount, P is the principal value, r is the rate and n is the number of times compounded per year, and t is the amount of years.
So, substitute 750 for P. 5 1/2% is the same as 5.5% or 0.055 (you move the decimal two places to the left and remove the percent symbol) so substitute this for r. Since it's increasing yearly, n is 1. So, our formula is:
[tex]A=750(1+0.055)^t[/tex]
Add:
[tex]A=750(1.055)^t[/tex]
Since the stock was bought 3 years ago, the value now is t=3. So, substitute 3 for t and evaluate:
[tex]A=750(1.055)^3[/tex]
Evaluate. Use a calculator:
[tex]A\approx\$880.68[/tex]
And we're done!
Formula: A = P(1 + r/n)^t
We have these variables:
P = 750
r/n = 0.055
t = 3
Substitute and simplify:
A = 750(1 + 0.055)^3
A = 750(1.055)^3
A = 880.68
Best of Luck!

Two circles have radii 16cm and 23cm. what is the difference between their circumference ?
43.96 cm
≈ 44 cm
Step-by-step explanation:Hi !
C₁ = 2π×r₁
C₂ = 2π×r₂
C₂ - C₁ = 2π×r₂ - 2π×r₁
= 2π(23cm - 16cm)
= 2×3.14×7
= 43.96 cm
≈ 44 cm
Good luck !
Answer:
44 cm
Step-by-step explanation:
r = 16,R = 23;2πR - 2πr
2π(R - r)

If this answer helps you plz mark as brainlist..Gavin was thinking of a number. Gavin adds 9 to it, then doubles it and gets an answer of 83.2. What was the original number?
Answer: it is 32.6
Step-by-step explanation:
The orginal number that Gavin was thinking of is 32.60.
What is the original number?
Let the orginal number be represented with y
Gavin adds 9 to the original number: 9 + y
The answer is doubled: 2(9 + y)
The answer is 83.2: 2(9+y) = 83.2
In order to determine the value of y, take the following steps:
Divide both sides of the equation by 2
9 + y = 41.60
Subtract 9 from both sides of the equation
y = 41.60 - 9
y = 32.60

The least-squares regression line Sˆ=0.5+1.1L models the relationship between the listing price and the actual sales price of 12 houses, with both amounts given in hundred-thousands of dollars. Let L represent the listing price and S represent the sales price.
Answer:
For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.
Step-by-step explanation:
The sales price is not predicted to increase by $1.1; it is predicted to increase by $110,000 because S is measured in hundred-thousands of dollars. The sales price will not decrease by $110,000; it is predicted to increase by $110,000.
A linear regression is represented as [tex]^\wedge y = mx + c[/tex].
The true option is: E. For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.
Given that:
[tex]^\wedge S = 0.5 + 1.1L[/tex]
From the general linear equation, we have:
[tex]1.1 \to[/tex] The slope
[tex]0.5 \to[/tex] The y-intercept
The slope is the difference between the sales price of one listing and the next.
From the question, we understand that the listed amount is in 100,000's.
This means that there is an increment of [tex]\$1.1 \times 100000[/tex] between the sales price of concurrent listing
So, we have:
[tex]\$1.1 \times 100000 =\$110000[/tex]
From the list of given options (see attachment), we can then conclude that (e) is correct.
Hence, for each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

What is the relationship between Za and Zb?
Answer: B
Step-by-step explanation:
∠a and ∠b are complementary angles. Complementary angles are two angles adjacent to each other that add up to 90°. We know this is true because of the 90° angle that is labelled.
Vertical angles are not adjacent to each other. They are across from each other, connected by the angle. They are equal in angles. It is clear that ∠a and ∠b are not equal in angles. Therefore, they are complementary angles.
