Answer:15
Step-by-step explanation:
Answer:
f(k) = 2*k + 1
Step-by-step explanation:
The 'f' function takes the variable, doubles it, and then adds 1.
So f(k) = 2*k + 1
f(g) = 2*g + 1
f(m) = 2*m + 1, and so on
It doesn't really matter which variable you use, the function still does the same thing to it.
Elevators starts 90 feet below ground level after 15s it is 20 feet below ground level. So the distance it has gone up is 70 feet because 90-20=70. Use this common equation: speed =distance/time and put your values in to get the correct answer. Time is 15s. You can eliminate c and d before you even start as the elevator is moving upwards. For the questions below just use a calculator.
The measurement of STR is 24 degrees
Answer:
y=(x-5)(x-4)(x+1)
Step-by-step explanation:
This has a leading co-efficient of 1, as there is a one in front of the leading term when you expand the equation.
