Which equation is a direct variation function?

Minchanka [31]

Answer:

y=x and y=1

4 x

Step-by-step explanation:

We know,

'Direct Variation function' is the function where two quantities vary directly i.e. variables x and y are said to be directly varying if 'y=kx' where k is the constant of variation.Thus, from the options, we see that the function,

y=x

is varying directly with the constant of variation i.e. k = 1.

y= 1

4 x

is also varying directly with constant k=1

Elena L [17]

It takes 1.875 seconds for the ball and the balloon to reach the same height

Step-by-step explanation:

A ball is thrown upward with an initial velocity of 40 feet per second from ground level

The height of the ball, in feet, after t seconds is given by h= -16 t² + 40 t

At the same time, a balloon is rising at a constant rate of 10 feet per second

Its height, in feet, after t seconds is given by h = 10 t

We need to find the time it takes for the ball and the balloon to reach the same height

∵ The height of the ball is given by h = -16 t² + 40 t

∵ The height of the balloon is given by h = 10 t

∵ They start at the same time t

∵ They have the same height h

Equate the two equations of h to find t

∴ -16 t² + 40 t = 10 t

- Subtract 10 t from both sides

∴ -16 t² + 30 t = 0

- Take -2 t as a common factor

∴ -2 t(8 t - 15) = 0

Equate -2 t by 0 and 8t - 15 by 0

∵ -2 t = 0 ⇒ divide both sides by -2

∴ t = 0 ⇒ initial time

∵ 8 t - 15 = 0 ⇒ add 15 to both sides

∴ 8 t = 15 ⇒ divide both sides by 8

∴ t = 1.875 seconds

It takes 1.875 seconds for the ball and the balloon to reach the same height

Thanh has scores of 54, 83, 67, and 73 on his first four math exams. What score must he make on the fifth exam to have an averag

miv72 [106K]

To solve this, you would set up the equation to find the arithmetic mean of the data. This equation is (53+83+67+73+x)/5=70, where x=the score of the fifth exam. First, you combine the constants to get (276+x)/5=70. Then, multiply both sides by 5 to get rid of the denominator, to give you 276+x=350. Then subtract 276 from each side to get x=74. So, Thanh needs to score a 74 on his last exam to get a 70 in the class.
