sergij07 [2.7K]

Answer:

f(-10) = 1,100

Step-by-step explanation:

f(-10) = (-10)^2 - (-10)^3

= 100 - (-1000)

= 1,100

A car is speeding at 60 miles per hour along a winding coastal highway. (The posted speed limit is 45 miles perhour). The speedi
Dmitry [639]
<span>8 minutes 20 seconds. First, lets determine who many miles per minute each vehicle moves by dividing each speed by 60. Speeder = 60 / 60 = 1 mile per minute. Police = 75 / 60 = 1.25 miles per minute. Other car = 45 / 60 = 0.75 miles per minute. Since the speeding car moves for 5 minutes before the police start to chase, that means that the speeding car will now be 5 + T miles down the road with T being the time the police has been chasing. The police will be 1.25 T. We're looking for when those two equations equal each other. So 5 + T = 1.25 T Subtract T from both sides 5 = 0.25T Divide both sides by 0.25 20 = T So it will take the police officer 20 minutes to catch up to the speeder. And they will both have traveled a total distance of 25 miles from the point where the speeder passed the police car. Now we need to figure out how far the law obeying car has moved during those 25 minutes. So 25 * 0.75 = 18.75 miles. The distance the law obeying car needs to travel to catch up to the police officer then becomes 25 - 18.75 = 6.25 miles. The number of minutes that the law obeying car needs to travel that distance is 6.25 / 0.75 = 8.333.... Which is 8 minutes 20 seconds.</span>

If the graph of the function f defined by
hoa [83]

Answer:

g(x) = 3x^2 + 3.

Step-by-step explanation:

f(x) = 3x^2 - 5.

First, the x-intercepts have to be calculated to determine the line of symmetry of f(x). For that, set f(x) = 0. Therefore:

3x^2 - 5 = 0.

x^2 = 5/3

x = 1.29 and x = -1.29. The midpoint of these two x-coordinates will be the line of symmetry, which is x = 0.

Therefore, if the graph is translated vertically upwards, it will move up the y-axis by the given amount. In this question, the amount is 8. Simply add 8 in f(x) to obtain g(x). Therefore:

g(x) = f(x) + 8.

g(x) = 3x^2 - 5 + 8.

g(x) = 3x^2 + 3.

Therefore, g(x) = 3x^2 + 3!!!
