Darn it i was looking for the same thing
Answer:
? = 22y^2
Step-by-step explanation:
Ask yourself, what times 20y will get me 40y^3?
The answer to this would be 2y^2.
When you multiply something to the denominator, you also have to do so to the numerator. Therefore, you are required to multiply 2y^2 to the 11 to get your '?' value.
11 x 2y^2 = 22y^2
Answer:
Rui will reach his lowest altitude after diving for 10 seconds
Step-by-step explanation:
In the quadratic equation y = ax² + bx + c, the coordinates of the lowest or the highest point is (h, k), where
- h =
and k = y at x = h
In the given question
∵ d(x) = 
x² - 10 x
∵ d represents his altitude in meters after x seconds
→ Compare it with the form above to find a and b
∴ a = and b = -10
∵ h =
→ Substitute the values of a and b in the rule to find h
∴ h = 
= 10
∴ h = 10
∵ h is the x-coordinate of the lowest point
∴ The time of the lowest altitude is 10 seconds
∴ Rui will reach his lowest altitude after diving for 10 seconds
The volume of the cylinder will be equal to 1017.87 cubic feet.
<h3>What is volume?</h3>
Volume is defined as the space occupied by any object in the three-Dimensions. For the cylinder, the volume will be calculated by radius and the height of the cylinder.
Given that:-
- A cylinder has a base radius of 9 feet and a height of 4 feet.
The volume of the cylinder will be calculated by using the formulas below:-
V = πr²h
V = π ( 9 )² 4
V = 1017.87 cubic feet.
Therefore the volume of the cylinder will be equal to 1017.87 cubic feet.
