Answer:
D) f(x) = 4(3)^x
Step-by-step explanation:
Plug y in for f(x) and plug in the points so if they are both true in one equation then it is correct.
A)
y = 3(4)^x
36 = 3(4)^2
36 = 3(16)
This is already incorrect
B)
y = 4(3)^-x
36 = 4(3)^-2
36 = 4(1/16)
36 ≠ 1/4
This is incorrect
I'm going to skip C because I believe D is correct:
D)
y = 4(3)^x
36 = 4(3)^2
36 = 4(9)
36 = 36
Now we plug in the other points
y = 4(3)^x
12 = 4(3)^1
12 = 4(3)
12 = 12
Answer:
Quadrant I and quadrant IV
Step-by-step explanation:
Given that cos x< 0
x < arccos 0
x < 90degres
Since cos s positive in the first and 4th quadrant, hence the angle lies in the Quadrant I and quadrant IV
18.7 rounded to the nearest whole number is 19.
Answer:
idk whats the x..........
All you have to do is multiply the l * w = Area
When you look at 26 ft and 15 ft, 21 ft and 10 ft, 29 ft and 18 ft, you'd know it wouldn't work since it's over 180.
So the dimensions of the ceiling are l = 20 ft; w = 9 ft
