Answer:
A The number of miles driven will always be greater than or equal to zero and cannot be less than zero.
Step-by-step explanation:
The domain of a function such as this is the set of values that realistically may be given as input to the function. We know of no way to ride a motorcycle a negative number of miles, so the domain must be non-negative numbers.
__
In real life, the domain is likely <em>non-negative integers</em>.
Let x and y be the number of dimes and quarters that Isaiah has. The sum of these variables should be 24 and the total value be $3.45. The equations that would best represent the situation are,
x + y = 24
0.1x + 0.25y = 3.45
The values of x and y are 17 and 7, respectively. Thus, the answer is the second choice.
Answer:
2.16 s
Step-by-step explanation:
When it hits the ground, height h=0 hence
0=45-10t-5t^{2}
5t^{2}+10t-45=0
t^{2}+2t-9=0
Using quadratic formula
x=-1+\sqrt 10\\ x=-1-\sqrt 10
Since time can't be negative, -1+\sqrt 10
t=2.16 s
