Answer:

c would be the closest

Step-by-step explanation:

All triangles equal 180*. so if you combine the 2 angles, which adds up to 77* then that would leave the third angle to be 103* but since that isnt an option choose c since its the closest.

Inverse of m(x)=2x^2-6

romanna [79]

$m(x)=2x^2-6\to y=2x^2-6\ \ \ \ |add\ 6\ to\ both\ sides\\\\2x^2=y+6\ \ \ \ \ |divide\ both\ sides\ by\ 2\\\\x^2=\dfrac{y+6}{2}\ \ \ \ |sqare\ root\ both\ sides\\\\x=\sqrt{\dfrac{y+6}{2}}\\\\Answer:\boxed{m^{-1}(x)=\sqrt{\frac{x+6}{2}}\ for\ x\geq-6}$

Find the first four terms of a sequence using the recursive definition. Please help

Ymorist [56]

Answer:

2, 5, 9, 19

Step-by-step explanation:

Using the recursive formula f(n) = 2f(n - 2) + f(n - 1)

with f(1) = 2 and f(2) = 5

f(3) = 2f(3 - 2) + f(3 - 1)

= 2f(1) + f(2) = (2 × 2) + 5 = 4 + 5 = 9

f(4) = 2f(4 - 2) + f(4 - 1)

= 2f(2) + f(3) = (2 × 5) + 9 = 10 + 9 = 19

The rule T 5, -0.5° Ro, 1800(x, ) is applied to FGH to

Yuki888 [10]

Answer:

Step-by-step explanation:

Given rule for the multiple translations is,

$T_{5,-0.5}.R_{0.180^{\circ}}(x,y)$

Apply the rule $R_{0,180^{\circ}}$ first.

(x, y) → (-x, -y)

This rule illustrates a rotation of the triangle FGH by 180° about the origin,

Vertices of ΔFGH are,

F → (1, 1)

G → (4, 5)

H → (5, 1)

After rotation vertices of the image triangle are,

F' → (-1, -1)

G' → (-4, -5)

H' → (-5, -1)

Further apply the rule,

$T_{5,-0.5}$

(x, y) → (x + 5, y - 0.5)

By this rule of translation,

F'(-1, -1) → F"{(-1 + 5), (-1 - 0.5)}

→ F"(4, -1.5)

G'(-4, -5) → G"[(-4 + 5), (-5 - 0.5)]

→ G"(1, -5.5)

H'(-5, -1) → H"[(-5 + 5), (-1 -0.5)]

→ H"(0, -1.5)
