If Mr. O'Brien cuts five lawns per day at $40 each, and he has a goal of making $3500, how many days will it take to reach that
Ede4ka [16]

Answer:

17 days and a half.

Step-by-step explanation:

First, we can find how much money he makes per day cutting lawns. This can be found with the equation:

40 x 5 = 200

He makes $200 a day cutting lawns.

Now we can divide his goal money ($3500) by his daily rate ($200) to get the number of days it will take to reach his goal.

3500 ÷ 200 = 17.5

It will take him 17.5 days to reach his goal.

Sarina throws a ball up into the air, and it falls on the ground nearby. The ball's
Anuta_ua [19.1K]

Answer:

Option C.

Step-by-step explanation:

It is given that the ball's height, in feet, is modeled by the function

f(x)=-x^2-x+3

where, x represents time in seconds.

We need to find the height of the ball when Sarina throws it. It means, we need to find the initial height of the ball.

Substitute x=0 in the given function, to find the initial height.

f(0)=-(0)^2-(0)+3

f(0)=0+0+3

f(0)=3

The height of the ball is 3 feet when Sarina throws it.

Therefore, the correct option is C.
