Answer:
Step-by-step explanation:
1000 Ohms
R = 1000
V = 9
I = V / R
I = 9 / 1000
I = 0.009
500000 Ohms
V = 9
I = V/R
R = 500000
I = 9 / 500000
I = 0.000018
(-4) (9x) + (-4) (-2)
-36x + 8
Answer:
-2
Step-by-step explanation:
f[g(x)
=f(3x^2+6x-2)
=2 (3x^2+6x-2)+14
=6x^2+12x-4+14
=6x^2+12x+10
f[g(-2)]=6 (-2)^2+12×(-2)+10
=12- 24+10
=-2
0.30 times 36 equals 10.80. The answer is $10.80
Answer:
Domain = R
Range =(0,infinity)
Step-by-step explanation:
Given a function as
y = 4(1/3)^x
The function does not have x or y in the denominator or any square root sign.
Hence we can assign any values to x.
Domain = R = Set of all real numbers = (-infinity, infinity)
Let us consider range.
We find that 4(1/3)^x is a multiple of 4 and powers of 1/3
Since power of 1/3 is always positive, y cannot take any negative value.
When x=0 y =4.
When x tends to -infinity, y tends to 0
So y cannot take the value 0 except at -infinity.
Range =(0,infinity)
