Answer:
35÷7=5
Step-by-step explanation:
we have 7 small boxes in an oval and there are 5 ovals
All the boxes add up to 35
This is a combination in which you choose 4 from 10.
The formula is
combinations = 10! / 4! * (10-4)!
combinations = 10! / 4! * 6!
combinations = 10 * 9 * 8 * 7 * 6! / 4! * 6!
combinations = 10 * 9 * 8 * 7 / 4 * 3 * 2
combinations = 10 * 3 * 7
combinations = 210

So, we need to add.
45 + 30 = 85.
$0.85 is your answer.
Glad I could help, and good luck!

Answer:
Option B)
is the correct option.
Step-by-step explanation:
<em>Exponential function is the one where, a constant is raised to the power of x, a independent variable.</em>
Here, only option B and D are such exponential functions, while option A is linear and option C is quadratic in nature.
Now, to verify which option is correct, we will input the values and check which has the least difference between the given values.
Or we can use the cost function,
, to find which function has the least error.
By applying the above results,we find Option B is correct.
3x^-2 can be written
3/x^2 because x^-2 is = 1/x^2
