Answer:
8/15 +5/15 = 12/15 = 4/5
Step-by-step explanation:
Y varies with x
so y/ x = constant
so, y1/x1 = y2/x2
6/9 = 18 / x2
so x2 = ( 9*18)/6
x2 = 27
another solution
y varis with x
y inceased by 3 times
so x must increase 3 time of the intial value
x(new) = 9*3 = 27
Answer:
At t=1, Rate of Change=-36.86
At t=10 hours, Rate of Change =-0.0088
Step-by-step explanation:
The function which describes the number of facts of a certain type which are remembered after t hours is given as:
To determine the Rate of Change at the given time, we first look for the derivative of f(t).
Applying quotient rule:
At t=1
=-36.86
At t=10 hours
=-0.0088
Answer:
42.475; approximately (42.48)

Answer:-10÷-20=2
Step-by-step explanation:
first off we know that a negative divided by a negative is a positive negative 10 is negative and -20 is negative and if we divide 10 into 20 that gives us to if we want to check our answer we multiply 2 by -10 which gives us 20
