Perfect squares are:
1,4,9,16,25,36,49,64,81,100,....
the sum of the digits of our biggest number is 16 so any perfect square bigger than 16 doesn't work for us
1-
1+0=1 so any number containing the digits will work(keep in mind we only will look into whole numbers because digits can't be negative or have fractions or be irrational)
thereful 10 works for our category
2-
0+4=4
1+3=4
2+2=4
22 13 31 and 40 will work two
3-
0+9
1+8
2+7
3+6
4+5
90 18 81 27 72 36 63 45 54
4-
0+16
1+15
2+14
3+13
4+12
5+11
6+10
7+9
8+8
79 97 88
so our set of numbers contain:
10 22 13 31 40 90 18 81 27 72 36 63 45 54 79 97 88
Answer:
4b = 8
Step-by-step explanation:
Given 12b = 24
This is written as (4 X 3)b = 24
⇒ 4b X 3 = 24
Dividing by 3 throughout, we have
4b =
= 8.
Therefore, the value of 4b is 8.
Answer:
A, H, I, J, E, and F I think. In order from b + 0.17b to 1.17b
Step-by-step explanation:
This kind of doesn't make sense but I just went with my best shot.
Answer:
y= -1/3(x) + 8
Step-by-step explanation:
slope of the 1st line = 3
slope of the line perpendicular to the first is its opposite reciprocal, so
slope of the 2nd line = -1/3
now we have a point and the slope of the perpendicular line, so we use the point slope formula to get:
y-7=-1/3(x-3)
y= -1/3(x) + 1 + 7
y= -1/3(x) + 8
Answer:
an=9+(n−1)3, an=3n+6
Step-by-step explanation:
Arithmetic Sequence:
d=3
This is the formula of an arithmetic sequence.
an=a1+d(n−1)
Step 1: Substitute in the values of
a1=9 and d=3.
an=9+(3)(n−1)
Step 2: Simplify each term.
an=9+3n−3
Step 3: Subtract 3 from 9.
an=3n+6
