Answer:
a) 5, 6
b) 8, 9
c) 9, 10
Step-by-step explanation:
It is useful to know the squares of small integers:
5² = 25
6² = 36
7² = 49
8² = 64
9² = 81
10² = 100
Then the problem becomes one of identifying the perfect squares the given number lies between
a) 25 < 35 < 36 ⇒ 5 < √35 < 6
b) 64 < 67 < 81 ⇒ 8 < √67 < 9
c) 81 < 93 < 100 ⇒ 9 < √93 < 10

Answer:
248000 miles
Step-by-step explanation:
if it takes 1
seconds then multiply 186,000 by 1
because 186,000 is equal to 1
Divide both sides by the number in front of x
so
4x=-16
x=-4
12=-3x
x=-4
-21=7x
x=-3
6x=-30
x=-5
Answer:
The answer to your question is the letter B
Step-by-step explanation:
Data
| 5 0 | | 2 - 1 |
| 3 -5 | | 2 - 2|
Process
1.- This is the product of two matrices 2 x 2 so the result will be a 2 x 2 matrix.
- Multiply the first row of the first matrix by the first column of the second matrix.
-Multiply the first row of the first matrix by the second column of the second matrix.
- Multiply the second row of the first matrix by the first column of the second matrix.
-Multiply the second row of the first matrix by the second column of the second matrix.
| 5 0 | | 2 - 1 | | (5 x 2) + (0 x 2) (5 x -1) + (0 x -2) |
| 3 -5 | | 2 - 2| = | (3 x 2) + (-5 x 2) (3 x -1) + (-5 x -2)|
= | 10 + 0 -5 + 0 |
| 6 - 10 -3 + 10|
= | 10 - 5 |
| -4 7|
