Answer:
90 games
Step-by-step explanation:
Given: Total number of team (n) = 10
Each team will play twice with each other.
We know that every team will play two game with each other except with itself, therefore each team will play 
⇒ Each team will play = 
∴ Each team will have 18 games with each other in the league.
Now, as there are total 10 teams and each team have 18 games each, however, we have to make sure that no team have more than two games with other team.
Example: 
Both the above game are same and it is a mistake to take two different game.
∴ Total number of games played by all team= 
⇒ Total games = 
∴ Rana have to schedule 90 games in the Volleyball league.
Answer:
x is approximately 226.3 feet
y is approximately 308.6 feet
z is approximately 226.3 feet
Step-by-step explanation:
The given parameters of the walls are;
The angle of elevation from the top of the shorter wall to the top of the opposing wall, θ₁ = 20°
From the diagram, the angle of depression from the top of the shorter wall to the bottom of the opposing wall, θ₂ = 45°
The distance from the bottom of the shorter wall to the base of the opposing wall, l = 320 feet
x = The height of the shorter wall = l × sin(θ₂)
∴ x = 320 feet × sin(45°) = 320 feet × (√2)/2 = 160·√2 feet ≈ 226.3 feet
∴ x ≈ 226.3 feet
By observation, we have;
y = x + z × tan(θ₁)
Where;
z = l × cos(θ₂)
∴ y = 160·√2 + 320 × cos(45°) × tan(20°) ≈ 308.6
y ≈ 308.6 feet
z = l × cos(θ₂)
∴ z = 320 × cos(45°) = 160·√2 ≈ 226.3
z ≈ 226.3 feet.
Answer:
I have no Idea where this question is trying to go because a quadratic function IS an exponential function. The exponent is 2.
Step-by-step explanation:
If the exponent on the exponential function is greater than 2, it will increase faster in the first quadrant than a quadratic equation.
If the exponent on the exponential function is less than 2, the quadratic equation will increase faster in the first quadrant
Answer:
use distributive property of the parenthesis first so
4+42-21+8 = 33
the answer correct is (5,3)
