Answer:
y = 0.64/x^3
Step-by-step explanation:
If y is inversely proportional to a^3, we can write the equation:
y * a^3 = k
Using a = 2 and y = 10, we have:
10 * 2^3 = k
k = 80
If a is directly proportional to x, we can write the equation:
a = c * x
Using x = 4 and a = 20, we have:
20 = c * 4
c = 5
Now, using the value of a = 5*x in the equation y * a^3 = 80, we have:
y * (5x)^3 = 80
y * 125x3 = 80
y = 80/(125x3) = 0.64/x^3
P(B) = 0.75.
For independent events, P(A and B) = P(A)*P(B). This gives us
1/8 = 1/6(x)
Divide both sides by 1/6:
1/8 ÷ 1/6 = x
1/8 × 6/1 = x
6/8 = x
3/4 = x
0.75 = x

Step-by-step explanation:
Let x represent the percent of increase in the tree's height and let n represent the number of years.
x= n (36/4343)

Answer:
There is no solution to this system.
Step-by-step explanation:
To solve this problem solve the second equation for y.
2x + y = 9
y = -2x + 9
Now that we have the value of y, we can put that in for y in the first equation and solve for x.
3y = -6x + 4
3(-2x + 9) = -6x + 4
-6x + 27 = -6x + 4
27 = 4
Because this is a false statement, we know that this system has no solution.
