A soccer player kicks a ball from the ground to a maximum height of 16 m. The high point in the trajectory of the ball occurs at a distance
of 19 m from the kicker. On the downward path, another player heads
the ball at a height of 2.2 m from the ground.
How far from the kicker in the line of the trajectory must a player be
to head the ball as described? Give the answer to the decimal places.

42.4

step-by-step explanation:

convert to decimal

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

55 degrees because 55+55=110 degrees

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
