Tobias dropped a tennis ball from a height of 60 meters. the time in seconds it takes for the ball to fall 60 feet is 0.25(radical60). find therr sets of approximations for the amount of time it will take. then determine how long it will take for the ball to hit the ground.

We are given

Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for the ball to fall 60 feet is 0.25(radical60).

so, time is

we have to approximate it's value

First approximation set:

we know that

we can take sqrt all the sides

we can simplify it

Divide all sides by 4

Second approximation set:

Divide all sides by 4

Third approximation set:

Divide all sides by 4

so, we get

......Answer

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

answer: d. $20

step-by-step explanation:

just took the test
