Solution:

W X Y Z is a rhombus.Also, 1 = 25°

As 1 and 2 are adjacent angles.

Also, opposite sides of rhombus are parallel.

Sum of two adjacent angles of rhombus is supplementary.

→1 + 2= 180°

→25°+ 2 = 180°

→2 = 180° - 25°

→2 = 155°

The function of the table is quadratic in nature and is given as follows: y = 2x² -1

<h3>What is a quadratic function?</h3>

A quadratic function is one of the following: f(x) = ax² + bx + c, where a, b, and c are positive integers and a, b, and are not equal to zero.

Given the nature of a quadratic function (y = ax² + bx + c) we pick three pairs of (x, y) from the table as follows:

A) (0, -1)

B) (1, 1)

C) (2, 7)

Then we say:

A) (0, -1) → -1 = a(0)² + b(0) + c =

-1 = c ..................................1

B) (1, 1) → 1 = a(1)² + b(1) + c =

1 = a + b + c.......................2

C) (2, 7) → 7 = a(2)² + b(2) + c

7 = a (4) + 2b + c

7 = 4a + 2b + c .................3

Using elimination and substitution, let us substitute equation 1 into equation 2;

that is

1 = a + b + (-1)

1 = a + b -1
1 + 1 = a + b

2 = a + b................................4

From the above we can also say,

b = 2 - a...................................5

substitute 5 into 3 we have

7 = 4a + 2 (2-a) + (-1)

7 = 4a + 4 - 2a - 1

7 = 4a - 2a + 4 - 1

7 = 2a + 3

7- 3 = 2a

4 = 2a

a = 4/2

a = 2

taking [a = 2] and [c = -1], subsitute these into equation 2

1 = a + b + c

1 = 2 + b + (-1)

1 = 2 + b - 1

1 = 2 - 1 + b

1 = 1 + b

b = 1-1

b= 0

Hence,

a = 2

b = 0

c = -1

Hence:

y = 2 * x² + (0) x + (-1)

y = 2x² -1

Hence the equation for the above table is y = 2x² -1

Please help me with this question

Licemer1 [7]

Answer:

$cos(x-\frac{3\pi }{2} )= \frac{-3}{4} cos(x)$

Step-by-step explanation:

Lets remember the following expression:

cos(x-a)= cos(x)*cos(a)+sin(x)*sin(a)

if a= -3 pi /2 then:

cos(x-3 pi/2)= cos(x)*cos(3pi/2) + sin(x)*sin(3pi/2)

Since cos (3pi/2) is located exactly at 'y' axis, its value=0

Moreover sin(3pi/2)= -1 because, that angle is located at 'y' axis, negative side

cos(x-3pi/2)= -sin(x)

But, we can simplify a little more since we now that tan(x)=3/4

That means that sin(x)/cos(x)= 3/4, from that expression we isolate sin(x) and we obtain that sin(x)=cos(x) * 3/4

Using the above conclusion we have that

cos(x-3pi/2)= -cos(x)*3/4
