How many different combinations can you make?</h3>
To find the total number of combinations, we need to find the number of options for each one of the digits.
There are 4 digits, such that each digit can only be an odd number.
- For the first digit, there are 5 options {1, 3, 5, 7, 9}
- For the second digit, there are 5 options {1, 3, 5, 7, 9}
- For the third digit, there are 5 options {1, 3, 5, 7, 9}
- For the fourth digit, there are 5 options {1, 3, 5, 7, 9}
The total number of different combinations is given by the product between the numbers of options, so we have:
C = 5*5*5*5 = 625.

The vertex should be at (1,2) because the equation is in vertex form.
Answer:
D - Area = 9/16pi cm²
Step-by-step explanation:
in order to evaluate this question , we will first of all find the radius using the formula for finding the circumference of a circle , we will then find the area of a circle.
<u>solution</u>
given that circumference of a circle = 3/2picm
recall that the formula for finding the circumference of a circle = 2πr
3/2picm = 2πr
multiply through by 2
3picm = 4pir
divide both side by 4pi
3pi cm/4pi = r
r = 3/4 picm
Recall that the Area of a circle = πr²
Area = pi ( 3/4)² cm
Area = 9/16pi cm²
Answer:
C. -4/3
Step-by-step explanation:
Parallel lines have the same gradient (steepness) and this means that they will never intersect.
