Answer:
y = <u>x</u> + 2
2
i think this is helpful
Step-by-step explanation:
equation= <u>y</u><u> </u><u>-</u><u> </u><u>1</u><u> </u><u> </u> = <u>1</u>
x - -6 2
then you close multiplication
= 2(y -1)= 1(x - -6)
2y - 2 = x - -6
you make Y as a subject
2y = x- -6 + 2
2y = x + 4
then you divide by 2 on both sides
<u>2</u><u>y</u> = <u>x</u> + <u>4</u>
2 2 2
y = <u>x</u> + 2
2
Base times height times length divided by 2
Answer: 2sin^2x+sin2x+cos2x=0 ..... (1).
By using the trigonometric identities below :
sin2x=2sinxcosx
cos2x=cos^2x-sin^2x
We substitute the trigonometric identities into (1).
2sin^2x+2sinxcosx+cos^2x-sin^2x=0
By combining like terms .
sin^2x+2sinxcosx+cos^2x=0.....(2)
The equation (2) is equivalent to the following expression (3).
(sinx+cosx)(sinx+cosx)=0 .....(3).
sinx+cosx=0
cosx=-sinx
divide both sides by cosx
1=-sinx/cosx
-1=sinx/cosx
sinx/cosx=tanx
substitute
-1=tanx
tanx=-1
tangent is negative in 2nd and 4th quadrants
tan135º=-1 (one answer)
tan315º=-1 (second answer)
Step-by-step explanation:
Please refer to the trigonometric identities used and explained above .
Answer:
1 3/8 Feet
Step-by-step explanation:
Take 2 1/2 and subtract 1 1/8 which gives u 1 3/8
if u don't understand fractions u can always turn ur fractions into decimals that's what I did :)
