A baseball player hits a high pop-up with an initial velocity of 32 meters per second, 1.3 meters above the ground. The height h(t) of the ball in meters t seconds after being hit is modeled by h(t)=−4.9t2+32t+1.3.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
