If i read it right it would be 4*10^2
Your post (" <span>f(x) = 2/3(6)x ") would be clearer and less ambiguous if you'd please format it as follows:
</span><span>f(x) = (2/3)(6)^x. The (2/3) shows that 2/3 is the coefficient of the exponential function 6^x. Please use " ^ " to indicate exponentiation.
Start by graphing </span><span>f(x) = (2/3)(6)^x. The y-intercept, obtained by setting x=0, is (0, 2/3). Can you show that the value of f(x) is (2/3)*6, or 4, at x=1, (2/3)*6^2, or 24, at x = 2, and so on? What happens if x becomes increasingly smaller? The graph approaches, but does not touch, the x-axis.
If you complete this graphing assignment, then all you'd have to do is to flip the whole graph over vertically, reflecting it in the x-axis. You'll see that the graph never touchs the x-axis. Therefore, the range of this flipped graph is (-infinity, 0).</span>
Answer:
Step-by-step explanation:
The equation representing the growth of the plant after x weeks is expressed as
y = 0.2x+2
Where
x represents the number of weeks.
y represents the height of the plant after x weeks in inches.
A.
The height of the plant after week 3 was about 2.6 inches. We can check by substituting x = 3 into the equation. It becomes
y = 0.2 × 3 + 2 = 2 + 0.6 = 2.6 inches. It is correct.
B is incorrect.
C.
The height of the plant after week 9 was about 3.8 inches. We can check by substituting x = 9 into the equation. It becomes
y = 0.2 × 9 + 2 = 2 + 1.8 = 3.8 inches. It is correct.
D is incorrect
We have 4(k-6)-(3k+2)=-5 and the answer is k=21
fun fact : by reading what i just right u just lost 5 sec of ut life
