Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
3/5 x 30 = 18 pages.
18 pages are filled.
30 - 18 = 12
12 pages are not filled.
1/4 x 12 = 3 pages
She wants to set aside 3 pages for her vacation.
12 - 3 = 9
She needs to fill up 9 pages before her vacation.
Answer: 9 pages
Answer:
152 photons
Step-by-step explanation:
Data provided in the question:
wavelength of the green light, λ = 550 nm = 550 × 10⁻⁹ m
Total energy = 5.50 × 10⁻¹⁷ J
Now,
Energy =
here,
n = number of photons
h = Plank's constant = 6.63 × 10⁻³⁴ J.s
c = speed of light = 3 × 10⁸ m/s
Therefore,
5.50 × 10⁻¹⁷ J =
or
( 5.50 × 10⁻¹⁷)( 550 × 10⁻⁹) = n(6.63 × 10⁻³⁴)(3 × 10⁸)
or
3025 × 10⁻²⁶ = n(19.89 × 10⁻²⁶ )
or
n = 152.086 ≈ 152 photons
9 + 0.04m = 81.40
0.04m = 81.40 - 9
0.04m = 72.40
m = 72.40 / 0.04
m = 1810 minutes <==
Answer:
B. 0
Step-by-step explanation:
The < sign means whatever is on the right side of the symbol should be greater than whatever is on the left side.
To solve this we need to understand that 0 is greater than -10. Then we need to make sure that 0 is greater than -5 and it is greater than -5.
Therefore the answer is 0
