Answer:
I think it would be 20%.
Step-by-step explanation:
$5 was taken off the original price, which is about 1/5 of $24.99. So, since 1/5 as a percent is 20%, I think the answer would be 20%.
Answer:
1.92 × 10¹²
Step-by-step explanation:
Given:
Frequency of the MRI, f₁ = 6.38 × 10⁷ Hz
thus,
the wavelength = C / f
where,
C is the speed of the light
therefore,
wavelength of the electromagnetic wave by MRI, λ₁ = C / f₁
or
λ₁ = C / 6.38 × 10⁷ Hz
now,
Frequency of the PET, f₂ = 1.23 × 10²⁰ Hz
Thus,
wavelength of the electromagnetic wave by PET, λ₂ = C / f₂
or
λ₂ = C / 1.23 × 10²⁰ Hz
therefore,
the ratio of the MRI wavelength to the PET scanning wavelength
= λ₁ / λ₂
or
=
or
=
or
Ratio of the MRI wavelength to the PET scanning wavelength = 1.92 × 10¹²
Answer:
cot(θ)=5/12
Step-by-step explanation:
(I'm going to replace theta with x to save time.)
Recall that sine is equal to opposite over hypotenuse. Thus:
sin(x)=12/13, this means that the opposite side is 12 while the hypotenuse is 13 (well, it doesn't have to be, but their ratios are).
Find the adjacent side using the Pythagorean Theorem.
13^2 = 12^2 + adj^2
adj^2 = 25
adj = 5.
Recall that tan(x) is opposite over adjacent. This means that cot(x) is adjacent is opposite.
Therefore: cot(x) = 5/12.
