I’ll explain part A and you can apply it to the other parts. The functions f(x), g(x), and m(x) are all equivalent to the given polynomials. So when it asks for f(x) + [g(x) - m(x)] you plug them in. The answer to Part A is 3x^2 +5x - z + [5x^2-3x+z - 2x^2 - 2x]. Combine the like terms (3x^2+5x^2-2x^2 = 6x^2 (because 3+5-2=6)) and so on until you’ve simplified it as much as possible!
Answer:
option a
Step-by-step explanation:
95 +x=180
x=180-95=85
85+31+y=180
116+y=180
y=180-116=64
Exponential growth function is given by f(t) = A(1 + k%)^t; where A is the initial value, k is the growth rate and t is the time period.
Therefore, the required function is
f(t) = 120,000(1 + 0.012)^t = 120,000(1.012)^t
After 15 years, the new population is 120,000(1.012)^15 = 120,000 x 1.1959 = 143,512
It’s 15, 21, 28 because it’s going up 1,2,3 etc and adding one each time it goes up
Answer:
15km x 1 mile/.621 km = 9.315 mi
1L = .264 gallons
So 9.315mi / .264 gal = 35.28 mi/gal
