Let vanessa's height = v.
twice of vanessa's height = 2v
64 decreased by... = 64 -
64 - 2v is your algebraic expression
hope this helps

<h3>
Compound interest</h3>
Compound interest is given by:

where A is the amount after t years, P is initial amount, r is the rate and n is the times compounded per period
Given that n = 1, r = 9% = 0.09, A = $7500 t = 11. Hence:

Answer: The answer is √6 mi.
The formula is: d = √(3h/2)
Pam:
h = 324 ft
d = √(3 * 324/2) = √486 = √(81 * 6) = √81 * √6 = 9√6 mi
Adam:
h = 400 ft
d = √(3 * 400/2) = √600 = √(100 * 6) = √100 * √6 = 10√6 mi
How much farther can Adam see to the horizon?
Adam - Pam = 10√6 - 9√6 = √6 mi
Answer:
y=1/2x
Step-by-step explanation:
Look at the graph, all you need is the first point.
Y is at 4 and X is at 2. We can divide y/x to get 4/2=1/2x
