F(x) is the function that represents a given equation. It is defined more specifically by rules or conditions to satisfy the whole formula/equation.
In this case, f(x) has an inverse proportion with x (e.g. f(x) = 1/x). The second parameter says that f(x) = -15 when x is 30. Given that condition, just look for the formula, among the choices, that will result to -15 when x = 30. The answer is:
D. f(x) = -450/x
This is just -450/30 = -15
Answer:
5/8 - 1/7 =.01785
0.6- 1.4 = -0.8

Answer:
120 routes are possible.
Step-by-step explanation:
The delivery driver has time to make deliveries at 3 locations among the 6 locations remaining.
So, the number of ways of choosing 3 out of 9 locations is given by :
6P3 ways (permutation because order of locations will matter)
= =
=
Hence, 120 different routes are possible.
Answer:
4.3 or 4.29
Step-by-step explanation:
Since it's a right angle triangle, you can use trig functions to solve.
You already know that the side across from P is 2 and the hypotenuse is , so you can use cosine.
degrees, or 1.342 radians.
Then, put in your angle for your tangent.
Finally, round to the hundredth:
4.301 becomes 4.3
4.294 becomes 4.29
Of course, these should be about the same, but will be slightly different because we rounded when computing cosine and tangent earlier.
