Answer:
1/x^2
1 over x to the power of 2
Answer:
18
Step-by-step explanation:
<em>First, use the equation for geometric mean; an=a1r^n-1</em>
*where is an is the number at an n term, r is the ratio and a1 is the first number of the sequence.*
12 = a1 r^5
27 = a1r^7
From the equations above,
a1 = 128/81
r = 3/2
Therefore, the 7th term is:
an = (128/81) (3/2)^6
an = 18
hope this helps :)
1) we find out the equation of the line.
Given a point (x₀,y₀) and the slope m, the slope-point form is:
y-y₀=m(x-x₀)
Data:
(3,4)
m=6
Therefore:
y-4=6(x-3)
y-4=6x-18
y=6x-18+4
y=6x-14
2) we find out y, when x=27
y=6*(27)-14
y=162-14
y=148
Answer: When x=27, then y=148.
Answer:
$145.00
Step-by-step explanation:
Since w is the number of weeks, substitute the w in (25+8w) with 15
y = 25 + 8(15)
y = 25 + 120
y = 145
The student saved $145.00 after 15 weeks
Answer:
54.56
Step-by-step explanation:
The number after the point is not 5 or higher
