Determine sum of the first 16 terms (S16) for an arithmetic series given the first tem is 9 (a = 9) and

Mekhanik [1.2K]

$\boxed{Sum=624}$

<h2>Explanation:</h2>

The nth term of an arithmetic series ( $a_{n}$ ) and the sum of an arithmetic series (Sum), for n terms, can be found as:

$a_{n}=a_{1}+d(n-1) \\ \\ Sum=\frac{n}{2}[2a_{1}+(n-1)d] \\ \\ \\ Where: \\ \\ a_{1}:First \ term \\ \\ d:Common \ difference \\ \\ n=Number \ of \ term$

So, in this exercise:

$a_{1}=a=9 \\ \\ d=4 \\ \\ n=16 \\ \\ \\ Sum=\frac{16}{2}[2(9)+(16-1)4] \\ \\ Sum=8[18+(15)4] \\ \\ Sum=8[18+60] \\ \\ Sum=8[78] \\ \\ \boxed{Sum=624}$

What is the slope of the line that passes through the given points (3 2) and (5 12)

forsale [732]

Slope is calculated using:
slope = (change in y) / (change in x)
slope = (12 - 2) / (5 - 3)
slope = 10/2 = 5

ehidna [41]

Applying the definition of alternate angles and angles on a straight-line: <u>m<ACB = 84°.</u>

<em><u>Recall:</u></em>

Alternate angles are congruent and have equal angle measures.

Angles on a straight-line = 180 degrees.

<em>The diagram showing the information and sketch of the Highland Park is attached below (see attachment).</em>

<em />

<em><u>Thus:</u></em>

m<BAC = 36° (given)

m<BCE = 60° (given)

<ACD = <BAC (alternate angles)

Therefore,

m<ACD = 36°

m<ACB = 180° - (m<ACD + m<BCE) (angles on a straight-line)

Substitute

m<ACB = 180° - (36° + 60°)

m<ACB = 84°

Thus, applying the definition of alternate angles and angles on a straight-line: <u>m<ACB = 84°.</u>
