We know that :

If f(x) and g(x) are Two Functions Defined under same Domain, then Composite Function : (f o g)(x) = f(g(x))

Given : f(x) = $\frac{2}{x + 3}$ and g(x) = $\frac{1}{2x}$

⇒ (f o g)(x) = f(g(x))

⇒ $(f\;o\;g)(x) = f(\frac{1}{2x})$

⇒ $(f\;o\;g)(x) = \frac{2}{\frac{1}{2x} + 3} = \frac{4x}{1 + 6x}$

I need help with C. Idk how to do it.

Rina8888 [55]

Answer:

after 1.25 hours

Step-by-step explanation:

1. make 130 your y value

130 = 220 - 72x

2. subtract 220 from both sides

-90 = -72x

3. divide by -72 on both sides

1.25 = x

A woman is emptying her aquarium at a steady rate with a small pump. The water pumped to a 12-in.-diameter cylindrical bucket, a

Temka [501]

Answer:

Therefore the rate at which water level is dropping is $\frac{11}{21}$ in per minute.

Step-by-step explanation:

Given that,

The diameter of cylindrical bucket = 12 in.

Depth is increasing at the rate of = 4.0 in per minutes.

i.e $\frac{dh_1}{dt}=4$

$h_1$ is depth of the bucket.

The volume of the bucket is V = $\pi r^2 h$

$=\pi \times 6^2\itimes h_1$

$\therefore V=36\pi h_1$

Differentiating with respect yo t,

$\frac{dV}{dt}=36\pi \frac{dh_1}{dt}$

Putting $\frac{dh_1}{dt}=4$

$\therefore\frac{dV}{dt}=36\pi\times 4$

The rate of volume change of the bucket = The rate of volume change of the aquarium .

Given that,The aquarium measures 24 in × 36 in × 18 in.

When the water pumped out from the aquarium, the depth of the aquarium only changed.

Consider h be height of the aquarium.

The volume of the aquarium is V= ( 24× 36 ×h)

V= 24× 36 ×h

Differentiating with respect to t

$\frac{dV}{dt}=24\times 36 \times \frac{dh}{dt}$

Putting $\frac{dV}{dt}=36\pi\times 4$

$36\pi\times 4= 24\times 36\times \frac{dh}{dt}$

$\Rightarrow \frac{dh}{dt}=\frac{36\pi \times 4}{24\times 36}$

$\Rightarrow \frac{dh}{dt}=\frac{11}{21}$

Therefore the rate at which water level is dropping is $\frac{11}{21}$ in per minute.

Solve for x: 3 − (2x − 5) < −4(x + 2)

Firdavs [7]

Answer:

A. x < -8 (first option)

Step-by-step explanation:

$3 - (2x - 5) < - 4(x + 2)$

$3 - 2x + 5 < - 4x - 8$

$8 - 2x < - 4x - 8$

$- 2x + 4x < - 8 - 8$

$2x < - 16$

$\boxed{\green{x < - 8}}$
