Answer:
4(9*12)+ (12*12)+ 1/2 *12*10*4=816m2
Step-by-step explanation:
Bottom square (12*12)
Add 4 sides rectangles 4(9*12)
Add 4 top triangles 4(1/2 *10*12)
Answer:
1) y = $10 + $2x
2) independent variable is the number of rides (x)
3) dependent variable in this equation is the total cost (y)
Step-by-step explanation:
In this scenario, we have two fixed values and two variables which would be the number of rides (x) and the total cost (y). Therefore, since the entrance fee is a fixed value it is added to the cost of each ride which is multiplied by the number of rides represented by the variable (x).
y = $10 + $2x
In this equation, the independent variable is the number of rides (x) because it is a separate value from the equation and does not depend on any other value. The dependent variable in this equation is the total cost (y) which depends on the number of rides that the individual goes on in order to have its own value.
F(x)= ∫[√x, 1] (2t - 1)/(t + 2) dt for x ≥ 0
<span>Let f(x) = ∫(2t - 1)/(t + 2) dt = ∫[2 + -5/(t + 2)] dt = 2t - 5Ln(t + 2) + constant </span>
<span>F(x) = f(1) - f(√x) = 2 – 5Ln(3) - (2√x - 4Ln(√x + 2) </span>
<span>F(1) = 2 - 5Ln(3) - (2√1 - 5Ln(√1 + 2) = 2 - 5Ln(3) - (2 - 5Ln(3)) = 0
