Answer:

Step-by-step explanation:

We must calculate the lateral area of a cylinder.

The formula is:

$A=2\pi rH$

r - radius

H - height

We have H = 6 cm and r = 3.5.

Substitute:

$A=2\pi(3.5)(6)=42\pi\ cm^2$

Use $\pi\approx\dfrac{22}{7}$

$A\approx42\left(\dfrac{22}{7}\right)=(6)(22)=132\ cm^2$

Answer:

Step-by-step explanation:

sin2x = 2sinx*cosx

= $2\sqrt{sin^{2}x }$ * cosx

= $2\sqrt{(1-cos^{2}x }$ * cosx

= 2 $\sqrt{1-\frac{3}{5} ^{2} } *\frac{3}{5}$

= $\frac{8}{5} * \frac{3}{5}$

= 24/25

What does product rule of exponents say

LuckyWell [14K]

The rules of exponents are
$( x^{m})( x^{n})=( x^{m+n})$
$\frac{ x^{m} }{ x^{n} } = x^{m-n}$
$x^{ \frac{m}{n} } = \sqrt[n]{ x^{m} }$
$( x^{m} )( y^{m} )=(yx)^{m}$
$( x^{m})^{n}=x^{mn}$
$( \frac{x}{y})^{m}= \frac{x^{m}}{y^{m}}$
$x^{-n}= \frac{1}{x^{n}}$
these are just some basic ones

What is the reflection of (-6, 13) over the x-axis?

Veronika [31]

For a reflection over the x-axis, we have to change the sign of the y-value. In this case, from 13 to -13. So the reflection is (-6,-13).
