The correct answer is d I believe so
Answer:45
Step-by-step explanation:
y varies directly as x^2
y=k x x^2
When y=5 x=3
5=k x 3^2
5=k x 9
K=5/9
Relationship is y=5x^2/9
y=(5x9^2) ➗ 9
y=(5x81) ➗ 9
y=405 ➗ 9
y=45
Answer:
Line 3.
Step-by-step explanation:
The mistake is in line 3.
' s equals fraction numerator negative 10'.
It should be - (-10) = 'positive 10'.
I would first suggest turning them all to one thing, like all decimals, or fractions. I chose decimals.
5.2, -5.6, 3.9, √21. To solve the square root, you have to simplify it. There is the square root of 3, times the square root of 7 which gets 21. These can't be simplified, so we can't simplify through that. But, the closest whole number that is a square root is 16. You can check by multiplying the same number together twice. Doing this will get you about 4.58
5.2, -5.6, 3.9, and ≈ 4.58. This is a simple ordering problem now.
It ends up as -5.6, 3 9/10, √21, 5.2
There are 2 decimals, one negative. There is one square root, and one mixed number. The square root is an infinite decimal when simplified
