Answer:
k(3) = 18
Step-by-step explanation:
k(n) = 2n²
k(3) = 2 * (3)²
k(3) = 2 * 9
k(3) = 18
Answer:
Option 5. Insufficient information
Step-by-step explanation:
Since the pool is in the form of a rectangle. Therefore opposite sides of the pool are equal.
Let the length of the pool be x and width of the pool is y feet.
Jan wants to swim across the diagonal of the pool therefore length of the diagonal will be = √x² + y²
perimeter of the pool is 16 feet
2(x + y) = 160 feet.
Now to get the length of the diagonal we should know at least one side of the pool.
Therefore information is insufficient for the calculation.
Option 5 is correct.
Answer:
c < 3
Step-by-step explanation:
We can first add 10 to both sides to remove the -10.
This is additive property of equality, where both sides must stay the same ratio, so we always use the same property on both sides unless simplifying what is already there.
So we now have c + 3c < 12.
As I mentioned less than 2 full sentences above, we can simplify without doing the same thing to both sides if it is already there, so we can add the c + 3c since it is already there.
We now have 4c < 12.
Then, we divide both sides by 4 to get c, and again mentioned about 4 sentences above, we need to divide both sides.
So we now should have c < 3.
NOTE: IF YOU HAVE A SIMILAR PROBLEM WHERE THE VARIABLE IS NEGATIVE LIKE -4a FOR EXAMPLE, THE INEQUALITY SIGN CHANGES DIRECTION. IN THIS PROBLEM, THAT IS NOT THE CASE, BUT FOR FUTURE PROBLEMS, THAT IS A <u>MUST</u>.

Answer:
House coordinate = (5, 1)
Library coordinate = (10, 13)
Step-by-step explanation:
Given :
House coordinate = (5, 1)
Library coordinate = (10, 13)
Distance between house snd library :
Distance = sqrt[(x2 - x1)² + (y2 - y1)]
x1 = 5, x2 = 10, y1 = 1, y2 = 13
Distance = sqrt[(10 - 5)² + (13 - 1)²]
Distance = sqrt[(5² + 12²)]
Distance = sqrt(25 +144)
Distance = sqrt(169)
Distance = 13
