Step-by-step explanation:
Given
Required
The sum of the series
This is calculated using:
![S_n = \frac{n}{2}[a_1 + a_n]](https://tex.z-dn.net/?f=S_n%20%3D%20%5Cfrac%7Bn%7D%7B2%7D%5Ba_1%20%2B%20a_n%5D)
Substitute 14 for n
![S_{14} = \frac{14}{2}[a_1 + a_{14}]](https://tex.z-dn.net/?f=S_%7B14%7D%20%3D%20%5Cfrac%7B14%7D%7B2%7D%5Ba_1%20%2B%20a_%7B14%7D%5D)
![S_{14} = 7[a_1 + a_{14}]](https://tex.z-dn.net/?f=S_%7B14%7D%20%3D%207%5Ba_1%20%2B%20a_%7B14%7D%5D)
Substitute values for a1 and a14
![S_{14} = 7[8 + 99]](https://tex.z-dn.net/?f=S_%7B14%7D%20%3D%207%5B8%20%2B%2099%5D)
Answer:
I believe the answer is D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Step-by-step explanation:
She can make 10 dresses if you split the number line into 20 parts and find 2/5. Therefore, it would then be grouped into 10 parts, each part 2/5ths of a yard.
Answer:
Step-by-step explanation:
Invert and multiply the way you would any fraction division problem. Then cancel common factors from numerator and denominator.
Angle measures are ∠M = 90° and ∠L = 24°
Step-by-step explanation:
- Step 1: In the figure, LM is a tangent to the circle N at point M.
Tangents create right angles at the point of contact with a circle.
So ∠M = 90°
- Step 2: Sum of angles in a triangle is equal to 180°
⇒ ∠L = 180° - (∠M + ∠N) = 180° - (90° + 66°)
= 180° - 156° = 24°
A: {-4, -2 -1, 2}<br>
B: {-4, 4}<br>
C: {-3, -2, 0, 2}<br>
D: {-4, -2, -1, 0, -2}
