What is the factored form of the polynomial?

IceJOKER [234]

d.(x - 9) (x - 3)

Step-by-step explanation:

x² - 12x + 27 = 0

x² - 9x - 3x + 27 = 0

x(x - 9) - 3(x - 9) = 0

(x - 9) (x - 3) = 0

What slope equals -1 and y intercept equals 3

Vlad [161]

Answer:

y = -x + 3

Step-by-step explanation:

The equation of a line with slope equal to -1 and y-intercept equal to 3 has the form

y = mx + b. With m = -1 and b = 3, we get: y = -x + 3

Think about this problem, please. Is there any way in which you could be clearer about what you wanted to learn?

A Cepheid variable star is a star whose brightness alternately increases and decreases. Suppose that Cephei Joe is a star for wh

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.
