Find the sum of the arithmetic series given a1=8,a14=99,n=14.

Sergeu [11.5K]

Answer:

The sum of the series is 749

Step-by-step explanation:

Given

$a_1 = 8$

$a_{14} = 99$

$n = 14$

Required

The sum of the series

This is calculated using:

$S_n = \frac{n}{2}[a_1 + a_n]$

Substitute 14 for n

$S_{14} = \frac{14}{2}[a_1 + a_{14}]$

$S_{14} = 7[a_1 + a_{14}]$

Substitute values for a1 and a14

$S_{14} = 7[8 + 99]$

$S_{14} = 7*107$

$S_{14} = 749$

The temperature of a cooling liquid over time can be modeled by the exponential function T(x) = 60(1/2)^(x/30) + 20, where T(x)

Alexus [3.1K]

Based on the scenario, the initial temperature would be :

28 = (60) (1/2)^x/30 + 20

(60) (1/2)^0/30 + 20 = 60 + 20 =

80 C

hichkok12 [17]

Answer:2/3

Step-by-step explanation:There are 52 cards in a standard deck: 13 ordinal cards (Ace - 10, Jack, Queen, King) and 4 of them - one to each suit (hearts, diamonds, clubs, spades) and so we have

There are 8 cards that fit the question (4 each of aces and kings).

And so in a random draw, the odds of drawing one of those 8 cards out of the total number of 52 is:8/52

which we can simplify:

8/52=2/13
