A Cepheid variable star is a star whose brightness alternately increases and decreases. Suppose that Cephei Joe is a star for wh
4vir4ik [10]

Answer:

\dfrac{0.7\pi}{5.3}\cos(\dfrac{2\pi t}{5.3})

0.16

Step-by-step explanation:

According to the question the mathematical model should be

B(t)=2.9+0.35\sin(\dfrac{2\pi t}{5.3})

Differentiating with respect to time we get

B'(t)=0.35\cos(\dfrac{2\pi t}{5.3})\times(\dfrac{2\pi}{5.3})\\\Rightarrow B'(t)=\dfrac{0.7\pi}{5.3}\cos(\dfrac{2\pi t}{5.3})

So, the rate of change of brightness after t days is \dfrac{0.7\pi}{5.3}\cos(\dfrac{2\pi t}{5.3})

After 1 day means t=1

B'(1)=\dfrac{0.7\pi}{5.3}\cos(\dfrac{2\pi\times 1}{5.3})\\\Rightarrow B'(1)=0.16

The rate of increase after one day is 0.16.

What ratios are equivalent to 4:3?<br> 7:2<br> 12/42<br> 28:21<br> 42:12
Karolina [17]
28:21

because the same number has to multiply both sides of the ratio. so number = 7 and:
4x 7 = 28
3 x 7 = 21

What is the equation of the line ?
Ronch [10]

Look at the picture.

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-3, -3) and (2, 0). Substitute:

m=\dfrac{0-(-3)}{2-(-3)}=\dfrac{3}{5}\\\\y-0=\dfrac{3}{5}(x-2)\qquad|\text{use distributive property}\\\\y=\dfrac{3}{5}x-\dfrac{6}{5}\qquad|\cdot5\\\\5y=3x-6\qquad|-5y\\\\0=3x-5y-6\qquad|+6\\\\3x-5y=6

Answer:

point-slope form: y=\dfrac{3}{5}(x-2)

slope-intercept form: y=\dfrac{3}{5}x-\dfrac{6}{5}

standard form: 3x-5y=6
