Answer:

Step-by-step explanation:

Formula of the circumference of the circle is 2*pi*r

1.A=pi*r^2=pi*3^2=9pi

2.A=pi*10.8^2=

3.r=14/2=7 so

A=pi*7^2=49pi

4. A=pi*(31/2)^2Km^2=15.5^2*pi

5. semicircle

A=pi*16^2/2cm^2=

6.A=pi*(22.6/2)^2=11.3^2*pi

Prove that if r is any rational number, then 3r2 − 2r + 4 is rational. The following properties may be used in your proof. Prope

Given:

Expression is

$3r^2-2r+4$

To prove:

If r is any rational number, then $3r^2-2r+4$ is rational.

Step-by-step explanation:

Property 1: Every integer is a rational number. It is Theorem 4.3.1.

Property 2: The sum of any two rational numbers is rational. It is Theorem 4.3.2.

Property 3: The product of any two rational numbers is rational. It is Exercise 15 in Section 4.3.

Let r be any rational number.

We have,

$3r^2-2r+4$

It can be written as

$3(r\times r)-2r+4$

Now,

3, -2 and 4 are rational numbers by property 1.

$r^2=r\times r$ is rational by Property 3.

$3r^2\text{ and }-2r$ are rational by Property 3.

$3r^2+(-2r)+4$ is rational by property 2.

So, $3r^2-2r+4$ is rational.

Hence proved.

Find angle sum therom

Allisa [31]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Sum of the interior angles of any triangle is 180° .

Thus ;

$y + 48° + 90° = 180°$

$y + 138° = 180°$

Subtract sides 138°

$y + 138° - 138° = 180° - 138° \\$

$y = 42°$

Use implicit differentiation to find an equation of the tangent line to the curve at the given point.

balu736 [363]

The tangent line to the curve can be determined by implicitly differentiating the equation of the curve. In this case, with the equation y sin 12x = x cos 2y, (π/2, π/4), the implicit differentiation is 12 y cos 12x dx + sin 12 x dy = -2x sin 2y dy + cos 2y dx; dx (12 y cos 12x - cos 2y) = dy (-2x sin 2y - sin 12x). Hence

y' = (12 y cos 12x - cos 2y) / (-2x sin 2y - sin 12x)
