Can y’all guys help please

tiny-mole [99]

Answer:

Step-by-step explanation:

What we need to do is find the operation between f(x) and g(x) that results in h(x).

Notice how there's a pattern, the value of h(x) is always equal to the values of g(x) and f(x) added together.

This can be represented by the expression (g+f)(x), the expression in D.

Write the general equation for the circle that passes through the points (-1,2)(4,2)(-3,4)

Fed [463]

Answer:

x² + y² - 3x - 13y + 18 = 0

Step-by-step explanation:

Recall that the general equation of a circle looks something like this:

x² + y² + Ax + By + C = 0

substituting each of the points into the equation we get:

for (-1,2)

(-1)² + (2)² + A(-1) + B(2) + C = 0

1 + 4 -A+2B + C = 0

-A + 2B + C + 5 = 0 ------------ eq 1

for (4,2)

(4)² + (2)² + A(4) + B(2) + C = 0

16 + 4 + 4A + 2B + C = 0

4A + 2B + C + 20 = 0 ------------- eq 2

for (-3,4)

(-3)² + (4)² + A(-3) + B(4) + C = 0

9 + 16 -3A + 4B + C = 0

-3A + 4B + C + 25= 0 ----- eq 3

Now we have a system of equations with 3 equations and 3 unknowns.

Solving for A, B and C, we eventually get:

A = -3, B = -13, C = 18

Substituting these into the general equation:

x² + y² + Ax + By + C = 0

x² + y² - 3x - 13y + 18 = 0

Determine el radio vector del punto medio del segmento que se forma al unir los puntos (-8, 7) y (6, 3).

tiny-mole [99]

Answer:

The radius vector is (-8, 7) and (-1 , 5).

Step-by-step explanation:

Determine the radius vector of the midpoint of the segment that is formed by joining the points (-8, 7) and (6, 3).

The end points are (- 8, 7) and (6, 3) .

The mid point is given by

$x = \frac{x' + x''}{2}\\\\y = \frac{y' +y''}{2}\\\\x =\frac{- 8 + 6}{2}=-1\\\\y = \frac{7+3}{2} = 5$

So, the radius vector is (-8, 7) and (-1 , 5).

HELP PLS A=45 help and how

MA_775_DIABLO [31]

Answer:

Step-by-step explanation:

the value of c angle is 35°

according to the question

$\frac{a}{ \sin( {45}^{o} ) } = \frac{15}{ \sin(35°) }$

$a = \frac{15 \times \frac{ \sqrt{2} }{2} }{ \sin({35}^{o} )}$

$a= 18.5$
