Answer:
Andre have more money after 4 weeks and after 6 week they have same amount of money.
Step-by-step explanation:
When Andre =100 then Elena =10.
After 4 week,
Andre = 100+(5*4)=100+20=120
In this time Elena = 10+(20*4) =10+80 = 90
After more 2months Andre have more 5+5=10
Then his total balance will be 120+10=130.
Than Elena after 2 week have 20+20=40.
Then her total balance will be 90+40=130.
That's mean 4 weeks+ extra 2 weeks total 6 weeks
Answer:
The volume is 2140.98 inches³
Step-by-step explanation
The basketballs are spherical, and it is known that the volume of a sphere is

Where V is the volume of the ball and r is its radius
They tell us that the ball measures 8.8 inches wide. This means that its diameter is 8.8 inches.
It is known that the radius of a sphere is equal to half its diameter.
Therefore, the radius r of the ball is:

r = 4.4 inches.
Then, they tell us to consider that the walls of the ball are infinitely thin, which means that we should not take into account their thickness in the calculation of the volume.
We already have all the data we need, now we proceed to calculate the volume.

Where V is the volume of only one of the balls
The volume of the six balls is V = 6 * 356.83 = 2140.98 inches³
Finally the volume is 2140.98 inches³
Answer:
h = 5 and k = -8.
Step-by-step explanation:
The parent equation is f(x) = x², which is the equation of a parabola having the vertex at point (0,0).
The original equation is given by g(x) = (x - 5)² + k, ⇒ y = (x - 5)² + k
⇒ y - k = (x - 5)²
So, the vertex of the original equation is at (5, k) which is given to be (5, -8)
Therefore, h = 5 and k = -8. (Answer)

Answer:
the desired line is y = 2x+1
Step-by-step explanation:
A line parallel to y=2x+5 has a very similar equation. All we have to do here is to write y=2x+5 as y=2x+b and find b for x = 1 and y = 3.
Replacing y with 3 and x with 1, we get 3 = 2(1) + b. Then b = 1, and the desired line is y = 2x+1
