1. Change x = 4t into x = 3t

$4t\cdot\frac{3}{4}=3t$ so

$y=(\frac{3}{4}t)^2-1=\frac{9}{16}t^2-1$

Answer A and D are wrong.

2. Change x = 4t into x = 2t

$4t\cdot\frac{1}{2}=2t$ and

$y=(\frac{1}{2}t)^2-1=\frac{t^2}{4}-1$

Answer b is correct.

3. Change x = 4t into x = 8t

$4t\cdot2=8t$ and

$y=(2t)^2-1=4t^2-1$

Answer C. is correct, E. is wrong.

Solve 4 square root of 3 = 8cos

sukhopar [10]

Therefore $\theta = 30^\circ$

Step-by-step explanation:

Given,

$4\sqrt{3 } =8 cos \theta$

$\Leftrightarrow cos \theta =\frac{4\sqrt{3} }{8}$

$\Leftrightarrow cos \theta =\frac{\sqrt{3} }{2}$

$\Leftrightarrow cos \theta =cos 30^\circ$

$\Leftrightarrow \theta = 30^\circ$

Therefore $\theta = 30^\circ$

Answer:

4.) 7 : 4 = 36[g] : x [g]

7 * x [g] = 4 * 36 [g]

7 * x [g] = 144 [g]

x [g] = 144 [g] / 7

x [g] ≈ 20, 57 [g]

5.) 3:2 250

3x + 2x =250

5x=250

x=50

3x=3*50=150

2x=2*50=100
