Answer:

Step-by-step explanation:

x³ - 4x² + 7x - 28 = <u>x³ - 4x²</u> + 7x - 7*4

                    = <u>x²(x - 4)</u> + 7(x - 4)

                    = (x - 4 )(x² + 7)

1.3( x + 2 )-( y - 6) <br> Help please
mestny [16]
Basically, we need to plug in the given values for the variables x and y into the given expression 1.3(x+2)-(y-6). First off, we can plug in all the given values into the expression, giving us 1.3(4+2)-(2-6). Now, perform the operations on the inside of the parentheses. Doing this, we get 1.3(6)-(-4). Now, we use the distributive property to simplify. This gives us 7.8+4. Finally, when we add the two numbers, we get \boxed{11.8}. Hope this helped!

Answer:

see below

Step-by-step explanation:

alaikum salam.

<u>2. </u><u>find</u><u> </u><u>cos Ф,   sin Ф,  tan Ф</u>

cos Ф = 5 / 13

Ф = 67.38

sin Ф = 12 / 13

Ф = 67.38

tan Ф = 12 / 5

Ф = 67.38

-----------------------

<u>3. find sin β,  cos β,  tan β</u>

sin <u>β</u> = 4 / 5

<u>β</u> = 53.13

cos <u>β</u> = 3 / 5

<u>β</u> = 53.13

tan <u>β</u> = 4 / 3

<u>β</u> = 53.13
