Given: g(x)=1/x+2 and h(x)=3x Check all restrictions on the domain of gOh.

Vlad [161]

The composite function $(g \circle h)(x)$ works like this:

Take a number $x$ as input
Evaluate h(x) = 3x. Let's call this output z.
Evaluate g(x) = 1/(z+2)

So, if we substitute back z = 3x, the final output is 1/(3x+2). We know that the denominator of a fraction can't be zero, so we must impose

$3x+2 \neq 0 \iff 3x \neq -2 \iff x \neq -\dfrac{2}{3}$

A sphere is just enclosed inside a right circular cylinder. If the volume of the sphere is 140 cm3, find the volume of the gap b

alexgriva [62]

-----------------------------------------------------------
Find Radius :
-----------------------------------------------------------
$\text {Volume of a sphere =} \dfrac{4}{3} \pi r^3$

$\dfrac{4}{3} \pi r^3 = 140$

$\pi r^3 = 140 \times \dfrac{3}{4}$

$\pi r^3 = 105$

$r^3 = \dfrac{105}{ \pi}$

$r = 3.22 \ cm$

-----------------------------------------------------------
Find volume of the cylinder :
-----------------------------------------------------------
$\text {Volume of the cylinder = } \pi r^2h$

$\text {Volume of the cylinder = } \pi ((3.22)^2(3.22 \times 2)$

$\text {Volume of the cylinder = } 209.77 \ cm^3$

-----------------------------------------------------------
Find volume of the gap :
-----------------------------------------------------------
$\text {Volume of gap = } 209.77 - 140$

$\text {Volume of gap = } 69.77 \ cm^3$

-----------------------------------------------------------
$\bf \text {Answer : } 69.77 \cm^3$
-----------------------------------------------------------

Help i give 5 stars and a crown

REY [17]

Answer:

See below.

Step-by-step explanation:

1a)

Angles:

48, 90, 90, a.

Add:

48 + 90
= 138 + 90
= 228

Subtract:

360 - 228
= 132.

Angle a: 132.

1b)

To get angle h above 180°, We need to add h + 164:

h + 164
= 110 + 164
= 274.

h = 110.

This is how to get h over 180°.
