Answer:

  q - p

Step-by-step explanation:

For complementary angles B and C, ...

  cos(C) = sin(B) = p

  sin(C) = cos(B) = q

Then the difference is ...

  sin(C) -cos(C) = q - p

The diagram rerpesents responses to a survey that include statements p and q . Which statement is true?
BARSIC [14]

Answer:

C. The number of responces p\vee q is also 46

Step-by-step explanation:

Note that:

  • p\wedge q means both p and q must hold;
  • p\vee q means either p or q must hold.

From the diagram,

  • the number of responses p\wedge q is 46;
  • the number of responces p\vee q is also 46;
  • the number of responces p\setminus q is 0;
  • the number of responces which are neuther p nor q is 20.

So, you can state that the correct answer is C

A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 1.5 feet, 30 feet a
Nimfa-mama [501]

Answer:

x₁ > x₂

Step-by-step explanation:

Both actions imply a parable trajectories, since both are projectile shot cases.

Let´s call x₁ maximum distance in the first case

The maximum height is just in the middle of the curve, therefore x₁ the maximum horizontal distance is equal to 60 feet.

In the second case, the parable curve is modeled by:

y = x₂*( 0.08 - 0.002x₂)    or  y = 0.08*x₂ - 0.002*x₂²

A second degree equation, solving for x₂ and dismissing the value x₂ = 0

we get:

y = 0       ⇒    x₂*( 0.08 - 0.002x₂) = 0    x₂ = 0

And 0,08 - 0.002*x₂ = 0

- 0.002*x₂ = - 0.08

x₂ = 0.08/0.002

x₂ = 40 f

Then  x₁ > x₂
