If EG=67, then EF=?<br> There is a picture below

ikadub [295]

If EG=67 we have (3x+7)+(5x-4)=67
let's simplify
$67 = (3x + 7) + (5x - 4) \\ 67 = 8x + 3 \\ 64 = 8x \\ \frac{64}{8} = x \\ 8 = x$
now we know x is 8 we can use this to find EF
since EF=3x+7
$3(8) + 7 = 24 + 7 = 31$
so we have EF is 31!

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:

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

$\frac{dB}{dt}\approx 5.595$
