Answer:5
Step-by-step explanation:

The abscissa is the x-coordinate of the ordered pair and the ordinate is the y-coordinate. The ordered pair is therefore given to be,
(abscissa, ordinate)
or (x , y)
From the given, it is stated that the ordinate is three more than twice the abscissa. The ordered pair can therefore be written as,
(x, 2x + 3)
If x = -1 then,
y = 2(-1) + 3 = 1
Ordered pair : (-1, 1)
If x = 0
y = 2(0) + 3 = 3
Ordered pair : (0, 3)
Hence, the answer to this is either the first choice or the second choice which appears to be just the same.

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
= ![\frac{\frac{C}{6.38\times10^7}}{\frac{C}{1.23\times10^{20}}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7BC%7D%7B6.38%5Ctimes10%5E7%7D%7D%7B%5Cfrac%7BC%7D%7B1.23%5Ctimes10%5E%7B20%7D%7D%7D)
or
= ![\frac{1.23\times10^{20}}{6.38\times10^7}](https://tex.z-dn.net/?f=%5Cfrac%7B1.23%5Ctimes10%5E%7B20%7D%7D%7B6.38%5Ctimes10%5E7%7D)
or
Ratio of the MRI wavelength to the PET scanning wavelength = 1.92 × 10¹²
