So, here we have an exponential function.
Remember that an exponential function has the form:
Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).
So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that
So,
For city B:
But something different happens with city C. This is not an exponential function, this is a linear function.
So,
Answer:
24.48757954 (I don’t know what it wants you to round it by
Step-by-step explanation:
Circumference= pi times diameter, radius is half of the diameter, so divide 153.86 divided by pi and then divide by 2 again
Answer:
x∉R
Step-by-step explanation:
1) Solve the quadratic equation 9x²-18x+14=0 using x=(-b±√b²-4ac)/2a:
x=(-(-18)±√(-18)²-4×9×14)/2×9
2) Evaluate the power, calculate the product and multiply the numbers:
x=(18±√324-504)/18
3) Calculate the difference:
x=(18±√-180)/18
4) The square root of a negative number does not exist in the set of Real Numbers:
x∉R
Answer:
50 % 2 = 25 25 is the answer
Step-by-step explanation:
(x)+(x+2)=3(x+4)-27
2x+2=3x+12-27
2-12+27=17=x
The three integers are 17,19,21
