Answer:
405 intrest
Step-by-step explanation:
the amount times years times percent gets the intrest
Let the horizontal distance is x and vertical distance is y and the distance between them is z
z^2 = x^2 + y^2
2z(dz/dt) = 2x(dx/dt) + 2y(dy/dt) divide by 2
z(dz/dt) = x(dx/dt) + y(dy/dt)
when y = 45 , x = 0 because the boy was under the balloon
after 3 secs: x = 15 * 3 = 45 , y = 5 * 3 = 15 , z = sqr(x^2 +y^2) = 75
z(dz/dt) = x(dx/dt) + y(dy/dt)
75(dz/dt) = 45(15) + 15(5) = 975
dz/dt = 13 ft/sec
Answer:
$0.04 per oz ( rounded to nearest cent)
Step-by-step explanation:
given
2 mangos ---> cost $0.99
1 mango -----> costs $0.99 ÷ 2 = $0.495
but we are also given than each mango is on the average 14 oz, hence
1 mango ---> weighs 14 oz -----> costs $0.495
1 oz ------> costs $0.495 ÷ 14 = $0.03536 (= $0.04 rounded to nearest cent)
Answer:
18
Step-by-step explanation:
Fifth grade has 80 students and sixth grade has 80 students. so if you get 90% of both then you have 72 and 72. Add and divide by 8 and you have the answer of 18 parent volunteers going.
Answer:
Here's my two cents worth about this one:
This is a discontinuous function - and it passes the vetical line test because any vertical line would only cut the "graph" in one place. The graph would have an infinite number of disconnected "peaks" and "valleys" because the x values along the number line are continuous. In other words, all the rationals would have y values of 1 and all the irrationals would have values of 0. The graph is definitely non-continuous because there aren't any "intermediate" y values - i.e., "y" is either 0 or 1 - and nothing in between !! Basically, the graph would be just "dots" at either y= 0 or at y =1. In a strange way though, this is an "even" function, because the negative of any positive rational would have a corresponding y value of 1 and the negative of any positive irrational would have a corresponding y value of 0. Thus, f(x) = f(-x). The y intercept would be the "dot" at (0, 1) - because 0 is rational. The "x" intercepts would just be the "dots" where the irrational numbers are located on the number line because "f(x)" would be 0 at those points!!! The domain is all real numbers, but there are onl two values for the "range" .....0 and 1 !!!
That's my "take" on this one !!!
