2.<br> If y = V9 – 3x, determine the value of x for which y will be a real number.

Pepsi [2]

Answer:

x ≤ 3

Step-by-step explanation:

The expression inside the radical ≥ 0, thus

solve

9 - 3x ≥ 0 ( subtract 9 from both sides )

- 3x ≥ - 9

Divide both sides by - 3, reversing the symol as a result of dividing by a negative quantity

x ≤ 3

Any value of x less than or equal to 3 ensures $\sqrt{9-3x}$ is real

The position of an object at a time t is given by s(t)=-4-2t. Find the instantaneous velocity at t=6 by finding the derivative

vagabundo [1.1K]

$\bf s(t)=4-2t\implies \cfrac{ds}{dt}=0-2\implies \left. \stackrel{v(t)}{\cfrac{ds}{dt}=-2} \right|_{t=6}\implies -2$

Solve a²b³-(ab)² if a=-2 and b=3

Lunna [17]

Answer:

The answer is 72.

Step-by-step explanation:

You have to put in the values of a and b into the expressions :

${a}^{2} {b}^{3} - {(ab)}^{2}$

$let \: a \: = - 2 \\ let \: b = 3$

${( - 2)}^{2} \times {(3)}^{3} - {( - 2 \times 3)}^{2}$

$= 4 \times 27 - { (- 6)}^{2}$

$= 108 - 36$

$= 72$
