Answer:

a_{n} = a_{1} + (n-1)d

a_n = the nᵗʰ term in the sequence

a_1 = the first term in the sequence

d = the common difference between terms

The general term of an arithmetic sequence can be written in terms of its first term a1, common difference d, and index n as follows: an=a1+(n−1)d. ... The nth partial sum of an arithmetic sequence can be calculated using the first and last terms as follows: Sn=n(a1+an)2.

You deposit $400 each month into an account earning 8% interest compounded monthly. Round to the nearest cent as needed. a) How

Debora [2.8K]

If I deposit $400 each month into an account earning 8% interest compounded monthly, I will have $6,517 in my account in 35 years. The total money that I will put into the account is $168,000. I will earn a total compound interest of $6,117.

Calculating the Sum of Money in 35 years

Given information is as follows,

Principal, P = $400

Rate = 8%

Time, T = 35 years

n = 12 (Compounded monthly)

The amount for compound interest is given as,

A = $P\frac{(1+\frac{R}{n} )^{nT} -1}{R/n}$

A = $400\frac{(1+\frac{0.08}{12} )^{12.35} -1}{0.08/12}$

A = 6,517.02

A = $6,517 (to the nearest cents)

Calculating the Amount Put in Account

Since, $400 is deposited every month for 35 years,

Amount Put in 35 years for this compound interest =$400 × 12 × 35

= $168,000

Calculating the Compound Interest

A = P + CI

Thus, the compound interest is given by,

CI = A - P

CI = 6517 - 400

CI = $6,117

I will earn a total interest of $6,117

In a parallel circuit, ET = 120 V, R = 30 Ω, and XL = 60 Ω. What is the phase angle (angle theta)?

sweet-ann [11.9K]

Phase angle (∅) in a parallel RL circuit is given by the formula; tan∅ $= \frac{I_{L} }{I_{L}}$

where $I_{L}$ is current through the inductor and given by $I_{L} = \frac{voltage}{X_{L}}$

and $I_{R}$ is current through the resistor and given by $I_{R} = \frac{voltage}{R}$

hence, tan∅ $= 30/60$ or ∅ = 26.565 degree

What the answer to #2 will give brainliest

Darina [25.2K]

The domain is the whole set of x values, so the domain would go from -infinity to positive infinity. The vertex would be (-5,0) because that is the lowest point on the graph. The Range would include -5 and go up to infinity.
