1) This is not an arithmetic sequence because it has n².
2) To find 5 first terms of this sequence, you can simply substitute n with 1,2,3,4, and 5, and calculate values of a(1),a(2), a(3), a(4) and a(5).
a(n) = 3n²- 1
n=1 a=3*1² - 1 = 3-1=2
n=2 a=3*2² - 1 = 11
n=3 a=3*3² - 1 =26
n=4 a=3*4² - 1 = 47
n=5 a=3*5² -1 = 74
2,11,26,47,74
Answer C. 2,11,26,47,74.

The largest area than can be enclosed is:


The dimensions of the triangle are:


Answer:
4 times
Step-by-step explanation:
How many times does 8 go into 33?
Divide
33/8
4.125
Ignore the decimal because it is not a whole number
4
4 times
Hope this helps :)
Volume=lwh
So if 7.35 m^3 is the volume, divide it by (4.2x0.5) (50 cm=0.5 m)
7.35/2.1=3.5
So the missing value, or width, is 3.5 meters
