NEED HELP ASAP !! PLEASE !!!
algol [13]

Answer:

The domain for A is 0, 1, 2, 3 and the range is 0, 5, 10, 15

and the domain for B is 2, 2, 4, 4 and the range is 4, 3, 2, 1

Only A is a function because for the same input value in B, there is two different output values which is not possible.

Step-by-step explanation:

I just wanna let you know so you don't waste any more points for us, but the domain is the x-values/ input/ stuff on the left of a given point. The range is the y-values, the output, and the stuff on the right side of a given point. So on (1, 7) for example, the 1 would be the domain number and the 7 would be the range number.

The y-axis values are the output/range and the x-axis values are the input/domain.

Hope this helps bro

A Cepheid variable star is a star whose brightness alternately increases and decreases. For a certain star, the interval between
victus00 [196]

Answer:

a) \frac{dB}{dt} = \frac{5\pi}{4.2} \cdot \cos \left(2\pi\cdot \frac{t}{4.2} \right), b) \frac{dB}{dt}\approx 5.595

Step-by-step explanation:

a) The rate of change of the brightness of the Cepheid can be determined by deriving the function in time:

\frac{dB}{dt} = \left(\frac{2\pi}{4.2} \right)\cdot 0.25\cdot \cos (2\pi\cdot \frac{t}{4.2})

\frac{dB}{dt} = \frac{5\pi}{4.2} \cdot \cos \left(2\pi\cdot \frac{t}{4.2} \right)

b) The rate of increase after one day is:

\frac{dB}{dt} = \frac{5\pi}{4.2} \cdot \left(2\pi \cdot \frac{1}{4.2} \right)

\frac{dB}{dt}\approx 5.595
