39. Enter the value for your 𝚫m15 to calculate the peak absolute magnitude of Supernova B.
    $$\mathrm{\Delta }{m}_{15}=$$

    $$M=-23.60+6.46\left(\mathrm{\Delta }{m}_{15}\right)$$

40. Enter the peak apparent magnitude (m) and absolute magnitude (M) for supernova B into the calculator to find its distance from Earth. (Don’t forget to include the negative sign for M.)
    $$m=$$

    $$M=$$

    $$d=\left(3.26\right){10}^{\frac{m-M}{5}}+1$$
