Answer:

$\frac{1}{5}$ is the answer

Step-by-step explanation:

$h(x)=\frac{x+3}{5} \\$

Substituting the -2 in place x

Therefore , h(-2) :

$\frac{(-2)+3}{5} \\\frac{-2+3}{5}\\\frac{1}{5}$

Answer:

$\huge\underline\bold\blue{ƛƝƧƜЄƦ}$

$h(x) = \frac{ x + 3}{5}$

value of X is given to us -2

so put it in the equation.

$h(x) = \frac{ - 2 + 3}{5}$

$h(x) = \frac{1}{5}$

so the value of x is 1/5

Hope it helps

Answer:

Step-by-step explanation:

so formula for the volume of a cylinder is:

(πr^2)*h

so the diameter is given to us which is

2r=10 cm

then r=5 cm

h=6 cm and r=5 cm so we just plug it in

(5^2)*6π

25*6π

150π cm^3 or approximately 471.239 cm^3

Find sin 2a and cot 2a:

geniusboy [140]

Answer:

$sin(2\alpha )=2(\frac{5}{12})(\frac{12}{13})=\frac{10}{13}\\cot(2\alpha ) = \frac{16511}{18720}$

Step-by-step explanation:

$\text{if } cos(\alpha)=\frac{12}{13}\\\text{That must mean we have a triangle with base 12, and hypotenuse 13.}\\\text{Using Pythagoras, we can determine the base of the triangle must be 5.}\\a^2+b^2=c^2 \text{, where c is the hypotenuse and a, b are the two other sides.}\\c^2-b^2=a^2\\\sqrt{c^2-b^2}=a\\\sqrt{13^2-12^2}=\sqrt{169-144}=\sqrt{25}=5\\\text{Therefore, }sin(\alpha) = \frac{5}{12}\\sin(2\alpha)=2sin(\alpha )cos(\alpha)\\\text{(From double angle formulae identities)}\\$

$sin(2\alpha )=2(\frac{5}{12})(\frac{12}{13})=\frac{10}{13}\\cos(2\alpha )=cos^2(\alpha)-sin^2(\alpha)\\cos(2\alpha )=(\frac{12}{13})^2-(\frac{5}{12})^2=\frac{16511}{24336}\\cot(2\alpha)=\frac{cos(2\alpha)}{sin(2\alpha)}=\frac{\frac{16511}{24336}}{\frac{10}{13}}=\frac{16511}{18720}$
