Answer:
431
Step-by-step explanation:
This is an arithmetic sequence with first term a₁ = -1 and common difference d = 6.
The nth term of an arithmetic sequence is:
a = a₁ + d (n − 1)
The 73rd term is:
a = -1 + 6 (73 − 1)
a = 431
:
The percent increase is found by finding the difference between the two prices and then dividing that different by the beginning price.
For this example it would be 65-39= $26. So $26/$39(the starting price) is 0.666... This is equivalent to about 66.67%. So, the price of the card increased by about 66.67%
Answer:
A. 31.4 feet
Step-by-step explanation:
The formula for circumference is given by
C = pi d
Since we know the diameter is 10 ft
C = pi * 10
pi is approximately 3.14
C = 3.14* 10
C = 31.4 ft
Answer:
x= 3 and x= -3
Step-by-step explanation:
x^2 -9 = 0
Factor x^2-9
(x+3)(x-3)
If x+3=0, then x= -3
If x-3=0, then x= 3
