Find an exact value.

Mathematics
1 answer:
Aleksandr-060686 [28]4 years ago
6 0

Answer:

(√2 − √6) / 4

Step-by-step explanation:

Rewrite using special angles.

sin(-11π/12)

sin((4−15)π/12)

sin(4π/12 − 15π/12)

sin(π/3 − 5π/4)

Use angle difference formula:

sin(π/3) cos(5π/4) − sin(5π/4) cos(π/3)

Evaluate:

(√3/2) (-√2/2) − (-√2/2) (1/2)

-√6/4 + √2/4

(√2 − √6) / 4

Simplify<br> f(x) = x² + 4<br> g(x)= xº + 5x - 1<br> find<br> f(x)- g(x)
hjlf
Simplified because I don’t know if x^o is the correct notation

(X^2 + 4) - (x^o + 5x - 1)
X^2 + 4 - x^o - 5x + 1

Then combine like terms

Alik [6]

Answer:

The answer is  <u>x = 2y</u>

Step-by-step explanation:

(3x + 2y) (3y + 2 y)

3x = 3y + 2y + 2y

3x = 7y

x = 7 ÷ 3

x = 2y

Write the equation with...<br><br> point: (9,0) <br> point: (-7,-4)
Vlad [161]
Easy
the equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)

find slope
slope between (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(9,0) and (-7,-4)
slope=(-4-0)/(-7-9)=-4/-16=1/4
slope os 1/4
a point is (9,0)
x1=9
y1=0
y-0=1/4(x-9)
we can put it into slope intercept and standard form
slope intercept
y=(1/4)x-(9/4)
standard
minus 1/4x
-1/4x+y=-9/4
times -4
x-4y=9
