Answer:

see explanation

Step-by-step explanation:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

if the sides are a, b, c , then the following must be true

a + b > c

a + c < b

b + c > a

F(x) = sqrt(x^2 + 3) ; g(x) = sqrt(X-2) Find f(g(x))

Hitman42 [59]

Answer:

F(x) = sqrt(x^2 + 3) ; g(x) = sqrt(X-2)

f(g(x))= √[{√(x-2)²+3}]

=√[{x-2+3}]

√(x+1)

Please assist me with these Alg 2 problems

ivanzaharov [21]

Answer:

$\displaystyle a_n = a_{n - 1} + 7$

$\displaystyle 4, 7, 10, 13, 16$

Step-by-step explanation:

A recursive formula is just a computation of all previous term in a sequence, in order to find value of $\displaystyle a_n.$ So, here is the recursive formula for arithmetic sequences:

$\displaystyle a_n = a_{n - 1} + d \\ \\ a_n = a_{n - 1} + 7$

I hope that the first answer is correct, and as always, I am joyous to assist anyone at any time.

The coordinates of point S are (8.4). What are the

Lerok [7]

Answer:

Co-ordinates of point R is (26,2)

Step-by-step explanation:

Given point:

Endpoint S(8,4)

Mid-point M of segment RS (17,3)

Let endpoint $R$ have co-ordinates $(x_2,y_2)$

Using midpoint formula:

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Where $(x_1,y_1)$ and $(x_2,y_2)$ are co-ordinates of the endpoint of the segment.

Plugging in values to find the midpoint of segment KN.

$M=(\frac{8+x_2}{2},\frac{4+y_2}{2})$

We know $M(17,3)$

So, we have

$(17,3)=(\frac{8+x_2}{2},\frac{4+y_2}{2})$

Solving for $x_2$

$\frac{8+x_2}{2}=17$

Multiplying both sides by 2.

$\frac{8+x_2}{2}\times 2=17\times 2$

$8+x_2=34$

Subtracting both sides by 8.

$8+x_2-8=34-8$

∴ $x_2=26$

Solving for $y_2$

$\frac{4+y_2}{2}=3$

Multiplying both sides by 2.

$\frac{4+y_2}{2}\times 2=3\times 2$

$4+y_2=6$

Subtracting both sides by 4.

$4+y_2-4=6-4$

∴ $y_2=2$

Thus co-ordinates of point R is (26,2) (Answer)
