A certain 300-term geometric sequence has first term 1337 and common ratio $-\frac12$. How many terms of this sequence are great

TEA [102]

There are 6 terms in the sequence greater than 1.

<h3>What is a geometric series ?</h3>

A geometric series is sum of infinite numbers which has a common ratio between its successive terms.

The missing common ratio value is -1/2

It is given in the question that

the number of terms in the sequence = 300

Sum = a₁ (1-rⁿ)/(1-r)

nth term is given by

aₙ = a₁r⁽ⁿ⁻ ¹⁾

1337(1/2)^(n - 1) = 1

(1/2)^(n - 1) = 1/1337

Applying log on both sides

log (1/2)^(n - 1) = log (1/1337)

(n - 1) log(1/2) = log(1/1337)

n = log (1/1337)/ log (1/2) + 1 ≈ 11.384

the 11th term is 1337(-1/2)^(10) ≈ 1.305

and

And the 12th term is 1337(-1/2)^11 = -.653

As the even terms are negative , they are less than 1 and , therefore the odd terms from 1 - 11 term will be positive and greater than 1.

Therefore there are 6 terms in the sequence greater than 1.

A family prepares an emergency kit for their home. The kit contains 63 gallons of drinking water. The family's daily drinking w

mr_godi [17]

Answer:

12 days

Step-by-step explanation:

Total gallons of the family's drinking water needs = gallons consumed by children + gallons consumed by adults

3 $\frac{1}{2}$ + 1 $\frac{3}{4}$ =

Converting to decimals

3.5 + 1.75 = 5.25 = 5 $\frac{1}{4}$

If there are 63 gallons, the water supply would last for :

63 / 5.25 =12 days

The table represents a linear function.<br><br>what is the slope of the function?

belka [17]

As we see, the table shows 0 equals 4, so 4 is our y axis. we now know our equation is y=_x +4.
lets subtract and find the slope using
$y1 - y2 \\ x1 - x2$
7-4 3
1-0 1 the slope is 3. lets substitute.
1(3)+4=7
the slope is 3.
