Multiply each term in the equation by 4/1.
9-2y+2y+4=24
Combine like terms
13=24
Because the result is false, it is no solution.
911 is the key of power of mind
Answer:

<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
Answer:
-52
Step-by-step explanation:
f(-4) = x3 + 3x2 + 2x – 8=
(-4)3+3(-4)2+2(-4)-8=
-12+-24+-8-8=
