List all x intercepts for y= -cos(1/2x + 1/5 pi) on the interval [-2/5pi,4pi]
Dahasolnce [82]
- cos ( 1/2 x + 1/5 π ) = 0 ( and because if cos α = 0, α= π/2 + k π, k ∈ Z )
1/2 x + π/5 = π/2 + k π,    k ∈ Z
1/2 x = π/2 - π/5 + k π  / * 2
x = π - 2π/5 + 2 k π
x = 3/5 π + 2 k π = 0.6 π + 2 k π
Answer:
If k = 0:  x 1 = 0.6 π = 3π/5
k = 1 : x 2 = 2.6 π = 13π/5

What Ratio can you write that compares days with games two days without them right this ratio three ways to
Ira Lisetskai [31]

Answer:

As a fraction: \mathbf{\dfrac{363}{2}}

As a colon,  363:2

By using the word to; we have: 363 to 2

Step-by-step explanation:

A ratio is a comparison of two quantities. We can write a ratio as a fraction, using the word “to,” or using a colon.

A rate is a ratio that compares two different units, such as distance and time, or a ratio that compares two different things measured with the same unit, such as cups of water and litres of petrol.

We can use a ratio to compare the number of days regardless of employing any professional sports events each year with the total number of days in a year.

The ratio with which we can write, that compares days with games in a year with two days without them can be written in three ways.

Suppose there are 365 days in a year and it appears that two days in that year exist without a game.

i.e.

365 - 2(days without game) = 363 days with a game

Then:

As a fraction: \mathbf{\dfrac{363}{2}}

As a colon,  363:2

By using the word to; we have: 363 to 2

labwork [276]

Answer:

Step-by-step explanation:

1/2(10x-8)=1/3(21-15x)

Opening the brackets

5x - 4 = 7 - 5x

5x + 5x = 7 + 4

10x = 11

x = 11/10

x = 1 1/10
