Answer:
Step-by-step explanation:
Geometric sequence
Each term in a geometric sequence can be computed as the previous term by a constant number called the common ratio. The formula to get the term n is
where 
is the first term of the sequence
The problem describes Georgie took 275 mg of the medicine for her cold in the first hour and that in each subsequent hour, the amount of medicine in her body is 91% (0.91) of the amount from the previous hour. It can be written as
amount in hour n = amount in hour n-1 * 0.91
a)
This information provides the necessary data to write the general term as
b)
In the 8th hour (n=8), the remaining medicine present is Georgie's body is
Answer:
60 weeks
Step-by-step explanation:
195 = 75 + (10 + 8)w
195 - 75 = (10 + 8)w
120 = (10 + 8)w
120 = (2)w
120 ÷ 2 = w
60 = w
Answer:
$1800
Step-by-step explanation:
twelve months in a year 12*2=24
75*24=1800
3916 so estimated it will be 3900
Step-by-step explanation:
<em>given</em><em>,</em>
<em>length</em><em> </em><em>=</em><em> </em><em>4</em><em>x</em><em>²</em>
<em>breadth</em><em>/</em><em>width </em><em>=</em><em> </em><em>y²</em>
<em>we </em><em>know</em><em>,</em>
<em>perimeter</em><em> </em><em>=</em><em> </em><em>2</em><em>l</em><em> </em><em>+</em><em> </em><em>2</em><em>b</em>
<em>so,</em>
<em>2</em><em>(</em><em>4</em><em>x</em><em>²</em><em>)</em><em> </em><em>+</em><em> </em><em>2</em><em>(</em><em>y²</em><em>)</em>
<em>→</em><em> </em><em>8</em><em>x</em><em>²</em><em> </em><em>+</em><em> </em><em>2</em><em>y²</em>
<em>option </em><em>A </em><em>is </em><em>correct</em>
