What is mZ1? 820 660 1

Tresset [83]

Answer:

∠1 = 148°

Step-by-step explanation:

the triangle interior angles = 180°

the unknown interior angle = 180° - 82° - 66° = 32°

∠1 = 180° - 32° = 148° because it is supplementary to 32° (adds together to total 180°)

The moon has a radius of about 939 leagues long. What is the total surface area of the moon? Rounded to the nearest whole number

muminat

Radius, r = 939 ft

Then:

Diameter, d = 1878 ft

Circumference, C = 5899.9110034416 ft

Area, A = 2770008.2161158 ft^2

AREA = 2770 if you're shortening.

HELP ASAP! 70 POINTS

Answer: f(x) and g(x) are inverses of each other

Step-by-step explanation:

To find the inverse of a function, swap the x's and y's and then solve for "y"

f(x) = 5x + 2

y = 5x + 2

Swap:

x = 5y + 2

-2 - 2

x - 2 = 5y

÷5 ÷5

$\dfrac{x-2}{5}=y$

****************************************************************

$g(x)=\dfrac{x-2}{5}\\\\y=\dfrac{x-2}{5}\\\\\text{Swap:}\\x=\dfrac{y-2}{5}\\\\\\(5)x=\dfrac{y-2}{5}(5)\\\\\\5x=y-2\\\\5x+2=y$

Given f(x)=sec x and g(x)=arcsin x, what is f(g(x))?

Dominik [7]

Answer:

Option 1 is correct.

Step-by-step explanation:

Given two functions f(x)=sec x and g(x)=arcsin x

we have to find f(g(x)).

f(g(x))=sec(arcsinx)=sec A where A=arc(sinx)

As, A=arc(sinx)

⇒ $x=sin A=\frac{P}{H}$

⇒ P=x and H=1 gives $B=\sqrt{1-x^2}$

hence, $sec A=\frac{H}{B}=\frac{1}{\sqrt{1-x^2}}$

hence, $f(g(x))=\frac{1}{\sqrt{1-x^2}}$

Rationalizing, we get

$f(g(x))=\frac{\sqrt{1-x^2}}{1-x^2}$

Option 1 is correct.
