Answer:
The exponential equation is;
y = 0.1•0.5^x
Step-by-step explanation:
Here, we want to get the exponential function represented by the table
Mathematically, the general form of an exponential function is;
y = a•b^x
By getting a and b, we have the exponential function
We can use any of the points;
Let us start with (0,0.1)
0.1 = a•b^0
anything raised to zero is 1
0.1 = a * 1
a = 0.1
Now, we have a
Let us work with the second point to get b
The point is (1,0.05)
0.05 = 0.1•b^1
0.05 = 0.1b
b = 0.05/0.1
b = 0.5
Thus, we have the equation as;
y = 0.1•0.5^x
Step-by-step answer:
1/8" long piece is not very much. However, mathematically,
we divide the total length by the length of each piece to get the number of pieces. So
4 2/5 / (1/8)
= (5*4+2)/5 * (8/1) [convert to fraction, and division to multiplication
= (22/5) * (8/1)
= 176/5
= 35 pieces with 1/5" left over.
The second one, and you as well ☺️
Answer:
6
Step-by-step explanation:
The product of four and nine is 36.
If you make 1/6 into a decimal, then multiply it by 36 you get 6!
I hope this helps, and have a great day! :)
Answer:
212
Step-by-step explanation:
<u>Rule</u>
- Subtract the 2nd number from the first to obtain the first digit(s) of the answer.
- Add the 2nd number to the 1st to obtain the last digit(s) of the answer.
5 - 3 = 2
5 + 3 = 8
Therefore: 28
9 - 1 = 8
9 + 1 = 10
Therefore: 810
8 - 7 = 1
8 + 7 = 15
Therefore: 115
6 - 2 = 4
6 + 2 = 8
Therefore: 48
7 - 5 = 2
7 + 5 = 12
Therefore: 212
