Answer:

option 3 ⇒ π

Step-by-step explanation:

The general equation of the given function is as following

f(x) = A cos (Bx)

Where A is the amplitude

and B = 2π/period

For the given function f(x) = cos 2x

B = 2

period = 2π/B = 2π/2 = π

The equation of the line that contains diagonal HM is y = 2/3 x + 7.
nirvana33 [79]

Answer:

The slope of the line that contains diagonal OE will be = -3/2

Step-by-step explanation:

We know the slope-intercept form of the line equation

y = mx+b

Where m is the slope and b is the y-intercept

Given the equation of the line that contains diagonal HM is y = 2/3 x + 7

y = 2/3 x + 7

comparing the equation with the slope-intercept form of the line equation

y = mx+b

Thus, slope = m = 2/3

  • We know that the diagonals are perpendicular bisectors of each other.

As we have to determine the slope of the line that contains diagonal OE.

As the slope of the line that contains diagonal HM = 2/3

We also know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.

Therefore, the slope of the line that contains diagonal

OE will be = -1/m = -1/(2/3) = -3/2

Hence, the slope of the line that contains diagonal OE will be = -3/2

Mrs. Cooper has $20 can she buy a museum tickets for 10 year old daughter a ticket for a self and a book that cost 3.99? Explain
Sladkaya [172]

No, because then she would have to pay 21 dollars  as a total and she only has 20.

Add adult plus Child,

5.75 + 11.25 = 17

add that to the book's price,

17+3.99= 2.99

it will exceed the budget by 99 cents.

9(y-4) -3y = 2(3y-2 need solved as fast as possible
Vlad [161]

Step-by-step explanation:

did you give us all the information ? the equating looks cut off.

so, from what I can see we have

9(y-4) - 3y = 2(3y-2)

let's try :

9y - 36 - 3y = 6y - 4

0 = 32

so, no, this can't be it. this does not have a solution. you must have cut off some additional information.
