For part 2, you would use 3 thousands, as that is the biggest amount possible so far. The, you would use 1 ten [instead of 16 ones] and then 6 ones bacuse that is the smallest amount.
Answer:
8 inches
Step-by-step explanation:
ROCK is a kite. The area of a kite is denoted by:
A = (1/2) * d1 * d2, where d1 and d2 are the diagonals
Here, the two diagonals are x and 15, and we know the area is 60, so plug these into the equation:
A = (1/2) * d1 * d2
A = (1/2) * 15 * x
60 = (1/2) * 15 * x
x = 120 / 15 = 8
Thus, x = 8 inches.
Answer:
1. Quadrant 2
2. Quadrant 1
3. Quadrant 2
4. Quadrant 4
5. Quadrant 4
6. Quadrant 2
7. Quadrant 2
8. Quadrant 3
Step-by-step explanation:
For this problem, we just need to follow the pattern of positive and negatives associated with each quadrant.
The first quadrant (+, +)
The second quadrant (-, +)
The third quadrant (-, -)
The fourth quadrant (+, -)
Using these patterns we can state what order pair correlates to which quadrant.
(-2.5, 2.1) --> Q2
(1/2, 3/4) --> Q1
(-10, 13) --> Q2
(2.5, -5.5) --> Q4
(9, -10) --> Q4
(-12, 3.4) --> Q2
(-5/8, 5) --> Q2
(-6.4, -6.3) --> Q3
Cheers.
We can write this as the difference of squares:
(5b⁸+8c)(5b⁸-8c)
To write as the difference of squares, take the square root of each term first:
√25b¹⁶ = 5b⁸; √64c² = 8c
Now we write this as a sum in one binomial and a difference in the other:
(5b⁸+8c)(5b⁸-8c)
