Please Help Me Simplify This

Answers

Answer 1

Step-by-step explanation:

Given

sin(α+β) cos(α-β) +cos(α+β) sin(α -β)

We can see it is in the formula of

sin(A + B) = sinA cosB + cosA sinB

So now

Sin ( α + β + α - β)

= sin 2α

Or we can write sin2α as

= 2 sin α * cos α

Hope it will help :)❤

Answers

Answer:

-26

Step-by-step explanation:

Hello There!

For this problem all we have to do is plug in -5 into x and calculate the value

so..

-3|-5|+2(-5)-1

so first things first | | means absolute value

The absolute values of -5 is 5 so the equation would be

-3(5) + 2(-5) - 1

-3*5=-15

2*-5=-10

-15-10=-25

-25-1=-26

so the answer would be -26

Solve the following system of equations graphically on the set of axes below.
y=1/6x+5

y=-3/2x-5

Answers

Answer:

(X,y)=(15/2,25/4) thanks for all the answers

Answer:

y=1/6x+5 -> plot points (-6,4),(0,5),(6,6)

y=-3/2 x -5 -> plot (-2,-2),(0,5),(2,-8)


Plot about 3 points for each line and connect them

Y=1/6 x +5
(Y=4)
4=1/6x+5
-1=1/6x
X=-6

(-6,4)

(Y=5)
5=1/6x+5
0=1/6x
x=0

(0,5)

Y=6
6=1/6x +5
1=1/6 x
X=6
(6,6)

Line y=1/6x+5 plot points (-6,4),(0,5),(6,6)


Y=-3/2 x -5
(Y=-8)
-8=-3/2 x -5
-3=-3/2 x
6=3x
x=2

(2,-8)

(Y=-2)
-2=-3/2 x -5
3= -3/2 x
-6=3x
x=-2

(-2,-2)

(Y=-5)
-5=-3/2 x -5
0=-3/2 x
x=0

(0,-5)

Line Y=-3/2 x -5 plot (-2,-2),(0,5),(2,-8)

-4x>6y - 54


I’m not sure how to completely solve this

Answers

Solving for X:

1) Divide both sides by-4.

[tex]x < - \frac{6y - 54}{4} [/tex]

2) Factor out the common term 6.

[tex]x < - \frac{6(y - 9)}{4} [/tex]

3) Simplify 6(y-9)/4 to 3 ( y - 9) / 2.

[tex]x < - \frac{3(y - 9)}{2} [/tex]

Therefor, the answer for x is x < - 3(y - 9)/2.

Solving for Y:

[tex] - 4x + 54 > 6y[/tex]

[tex] \frac{ - 4x + 54}{6} > y[/tex]

[tex] \frac{ - 2(2x - 27)}{6} > y[/tex]

[tex] - \frac{2(2x - 27)}{6} > y[/tex]

[tex] - \frac{2x - 27}{3} > y[/tex]

[tex]y < - \frac{2x - 27}{3} [/tex]

Therefor, the answer for Y is y < - 2x-27/3.

4 can divide both the numerator and denominator. So divide  the numerator and denominator by 4

This gives 402 / 67

Th 67 multiplication table

67 x 1 = 67

67 x 2 = 134

67 x 3 = 201

67 x 4 = 268

67 x 5 = 335

67 x 6 = 402

the value of the expression would thus be 6

71 + 50 -1 + 6x = 180

    120  + 6x   = 180

Answers

Answer:

Diameter = 19.33

Step-by-step explanation:

Imaging a radius line from O to the endpoints of the 7. call this line R.

Label the part of the vertical line from O to the 90 degree intersection y.

Now you have a right triangle.

Using the Pythagorean theorem:

R² = 7² + y²

also

y = R - 3

substitute for y:

R² = 49 + (R-3)²

R² = 49 + R² - 6R + 9

simplify:

0 = 58 - 6R

6R = 58

R = 9.6667

Diameter = 2(9.6667) = 19.33

Answers

Answer:

49.865%

Step-by-step explanation:

Given that:

μ = 4 ; σ = 1

For x = 4

P(x < 4) :

Z score (x - μ) / σ

P(x < 7) - P(x < 4)

((7 - 4) / 1) - ((4 - 4) / 1)

P(Z < 3) - P(Z < 0)

Usibg the Z probability calculator :

0.99865 - 0.5

= 0.49865

= 0.49865 * 100

= 49.865%

The length of a rectangle is five more than triple the width. If the perimeter is 154 inches, what are the dimensions

Answers

Answer:

Width = 18 inches

Length = 59 inches

Step-by-step explanation:

The length of a rectangle is five more than triple the width. If the perimeter is 154 inches, what are the dimensions

Perimeter of a rectangle = 2L + 2W

The length of a rectangle is five more than triple the width.

L = Length = 5 + 3W

W = Width

If the perimeter is 154 inches, what are the dimensions

Hence,

154 = 2L + 2W

154 = 2(5 + 3W ) + 2W

154 = 10 + 6W + 2W

Collect like terms

154 - 10 = 8W

144 = 8W

W = 144/8

W = 18 inches

Length = 5 + 3W

Length = 5 + 3(18)

Length = 5 + 54

Length = 59 inches

[tex]x =\frac{-26}{3}[/tex]

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x+32−7x=−2(5x+10)

3x+32+−7x=(−2)(5x)+(−2)(10)(Distribute)

3x+32+−7x=−10x+−20

(3x+−7x)+(32)=−10x−20(Combine Like Terms)

−4x+32=−10x−20

−4x+32=−10x−20

Step 2: Add 10x to both sides.

−4x+32+10x=−10x−20+10x

6x+32=−20

Step 3: Subtract 32 from both sides.

6x+32−32=−20−32

6x=−52

Step 4: Divide both sides by 6.
