Drag the tiles to the boxes to form correct pairs
Brums [2.3K]

Answer:

1) sin^{-1}(\frac{1}{\sqrt{2} })=45

2) cos^{-1}(\frac{\sqrt{3} }{2})=30

3) tan^{-1}(\sqrt{3})=60

4) sin^{-1}(1)=90

Step-by-step explanation:

1) Value of sin^{-1}(\frac{\sqrt{2} }{2}) =sin^{-1}(\frac{1}{\sqrt{2} })

since sin45° = 1/√2

Therefore sin^{-1}(\frac{1}{\sqrt{2} })=45

2).Value of cos^{-1}(\frac{\sqrt{3} }{2})

Since cos 30° = √3/2

Therefore cos^{-1}(\frac{\sqrt{3} }{2})=30

3). Value of tan^{-1}(\frac{3}{\sqrt{3} }) = tan^{-1}(\sqrt{3})=60

since tan 60° = √3

therefore tan^{-1}(\sqrt{3})=60

4). Value of sin^{-1}(1)

Since sin90°=1

Therefore sin^{-1}(1)=90

In a direct variation equation, f(x)=6 when x = 4. What is the direct variation equation?
jeyben [28]

Answer:

f(x) = \dfrac{3}{2}x

Step-by-step explanation:

The general direct variation equation is

y = kx

Plug in x = 4 and y = 6 and solve for k.

6 = k * 4

4k = 6

k = 6/4 = 3/2

f(x) = \dfrac{3}{2}x

9. Solve for x: 2x – y = (3/4)x + 6.​
AlekseyPX

Answer:

x = 4(y + 6)/5

Step-by-step explanation:

2x - y = (3/4)x + 6

2x - (3/4)x = y + 6

(8x - 3x)/4 = y + 6

5x/4 = y + 6

5x = 4(y + 6)

5x = 4y + 24

x = (4y + 24)/5

Therefore, x = 4(y + 6)/5
