Answer:

33+11\sqrt{3}.

Step-by-step explanation:

sin(30º) = 0,5

\frac{1}{2} = \frac{b}{c} \\ b = \frac{c}{2} \\ b = 11.

c^2=a^2+b^2 \\ a^2 = c^2-b^2\\ a^2=22^2-11^2 \\ a^2 = 484 - 121 = 363 \\ a = \sqrt{363} \\ \sqrt{363} = \sqrt{3*121} = 11\sqrt{3}.

P = a+b+c \\ P = 11+22+11\sqrt{3} \\ P = 33+ 11\sqrt{3}.

The midpoint of UV is (5, -10). The coordinates of one endpoint are U(3,6). Find the coordinates of endpoint V.
Grace [21]

The answer is (7, -26) for The second endpoint.  

We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.

(Ux + Vx)/2 = Mx

(Vx + 3)/2 = 5

Vx + 3 = 10

Vx = 7

And now we do the same thing for y values

(Uy + Vy)/2 = My

(Vy + 6)/2 = -10

Vy + 6 = -20

Vy = -26

This gives us the final point of (7, -26)

Find f(x) if it is known that f(x+3)=4x+12.
MArishka [77]

Solution:

we are given that

f(x+3)=4x+12

we have been asked to find f(x).

we can find the value of f(x) by re-writing the given function in the form of f(x+3) and thereafter we will replace (x+3) by x.

we can re-write the given function as below

f(x+3)=4(x+3)\\\\\Rightarrow f(x)=4x\\

Hence the expression representing f(x) is f(x)=4x+3.
