What are the period and amplitude of the function?
lianna [129]

ANSWER

Period: 2π , amplitude: 4

EXPLANATION

The graphed function is

y =  4\cos(x)

The amplitude of this function is

|4|  = 4

The period is 2π because there is no phase shift hence the period is still equal to the parent function.

Period: 2π , amplitude: 4

The expression (y-20)(y5)3 is equivalent to ya. What is the value of a?
Leno4ka [110]

Answer:

y¹⁵-20y¹⁴

Step-by-step explanation:

I'm going to assume that your problem looks like this

(y-20)(y^5)^3

(x^n)^y=x^{n*y}

which means we have

(y-20)*y^{15}\\\\y^{16}-20y^{15}=ya\\\\*y^{15}-20y^{14}=a

Write a rational number in fraction form that is equivalent to -1.\overline{5}
lorasvet [3.4K]

Answer:

\dfrac{-14}{9}.

Step-by-step explanation:

The given number is -1.\overline{5}.

We need to find a rational number in fraction form that is equivalent to given number.

Let x=-1.\overline{5}

x=-1.555...     ...(1)

Multiply both sides by 10.

10x=-15.555...  ...(2)

Subtracting (1) from (2), we get

10x-x=-15.555...-(-1.555...)

9x=-14

Divide both sides by 9.

x=\dfrac{-14}{9}

Therefore, the required rational number is \dfrac{-14}{9}.
