Answer:

$\frac{31}{20}\pi$

Step-by-step explanation:

The circumference of circle G is 2pi, which means that HJ is equal to 81/360*2pi = 9pi/20, which means that RJ is equal to 18pi/20-9pi/20 = 9pi/20. Therefore, RHJ is equal to the circumference of the area minus RJ, which is equal to 40pi/20 - 9pi/20 = 31pi/20

I hope this helps

miskamm [114]

Answer:

Step-by-step explanation:

$f(x) = x - 8 \\ \\ g(x) = |x + 8|$

To find (f ∘ g)(x) , substitute g(x) into f(x). That is for every x in f (x) replace it with g (x)

That's

Which equation represents a line that is parallel to 2x-3y=9

Sever21 [200]

Two lines are parallel if they have the same slope but a different y intercept. A line with the same slope and y int as another one will be the exact same
Slope in standard form is -a/b, so your slope is 2/3 and your y int is -3
For example:
y=2/3x+1

Which best explains why the expression plus or minus StartRoot b squared minus 4 a c EndRoot cannot be rewritten as b plus or mi

Gelneren [198K]

Answer:

C) The square root of terms separated by addition and subtraction cannot be calculated individually.

Step-by-step explanation:

sqrt(b² - 4ac) is not equal to

b - sqrt(4ac)

Because when you square b - sqrt(4ac), it's not b² - 4ac..

(b- sqrt(4ac))² = b² - 2bsqrt(4ac) + 4ac
