Answer:
Hence, Grasshopper will land on the ground after 1.5 sec.
Step-by-step explanation:
It s given that:
The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function:

Now we are asked to find:
In how many seconds will the grasshopper land on the ground?
i.e. we have to find the value of t such that h(t)=0
i.e.

i.e. we need to find the roots of the given quadratic equation.
On solving the quadratic equation or plotting it's graph we could observe that the point where h(t)=0 are:

As time can't be negative hence we will consider:

Hence, grasshopper will land on the ground after 1.5 sec.
Answer: $53
Step-by-step explanation:
17+ .09m = 9 + .11m
8 = .02m
m = 8/.02= 400 minutes for the two plans to cost the same
9+.11(400) = 9+ 44 = $53 when they cost the same
17+.09(400) = 17 +36 = $53

Translate words into numbers.
13/(1 3/7)
First convert to improper fraction.
13/(10/7)
Then, note that division is the same as multiplying by the divisor's reciprocal.
13x7/10=9.1
answer: $9.10 per kilogram
Step-by-step explanation:
Multiply the first equation by 7 and the second by 2
