Answer:

The answer is x < 4

Step-by-step explanation:

1) Subtract 6 from both sides.

$4x < 22 - 6$

2) Simplify 22 - 6 to 16.

$4x < 16$

3) Divide both sides by 4.

$x < \frac{16}{4}$

4) Simplify 16/4 to 4.

$x < 4$

Therefor, the answer is x < 4.

Answer:

- time = 1second

- maximum height = 16m

Step-by-step explanation:

Given the height of a pumpkin t seconds after it is launched from a catapult modelled by the equation

f(t)=-16t²+32t... (1)

The pumpkin reaches its maximum height when the velocity is zero.

Velocity = {d(f(x)}/dt = -32t+32

Since v = 0m/s (at maximum height)

-32t+32 = 0

-32t = -32

t = -32/-32

t = 1sec

The pumpkin reaches its maximum height after 1second.

Maximum height of the pumpkin is gotten by substituting t = 1sec into equation (1)

f(1) = -16(1)²+32(1)

f(1) = -16+32

f(1) = 16m

The maximum height of the pumpkin is 16m

Find the domain for the rational function f of x equals quantity x end quantity divided by quantity x minus 5 end quantity.

Gennadij [26K]

Answer:

All real numbers except for 5.

Step-by-step explanation:

$f(x)=\frac{x}{x-5}$

The domain of rational functions is determined by the denominator. The denominator cannot equal zero since if they do, the function will be undefined.

Thus, we need to find the zero(s) of the denominator to determine the domain.

$x-5=0$

$x=5$

Therefore, the domain of the rational function is all real numbers except for 5.

In set builder notation, this is:

$\{x|x\in \mathbb{R}, x\neq 5\}$
