1. B A C
Reason:
A: 4
is 12.6
B: the Square root of 18.7 is 4.32
2. a
Reason: the square root of 80 is 8.9, thus closest to 9 from all the others.
3. C
Reason: 6/7 = 0.86, and the square root of 3/4 = 0.87

Answer:

Step-by-step explanation:
Given
w = weight
a = age
Required
Represent the weight as a function of age
When writing a function.

means that y is a function of x
Using the above to answer the given question, we have:

Which means w is a function of a
and can be rewritten as:

Answer:
x = 0, x = 
Step-by-step explanation:
Given
8x² = 2x ( subtract 2x from both sides )
8x² - 2x = 0 ( factor out 2x from each term )
2x(4x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
2x = 0 ⇒ x = 0
4x - 1 = 0 ⇒ 4x = 1 ⇒ x =
