Answer: B

Step-by-step explanation:

The parabola has an open hole at x=2, and the line has a closed hole at x=2.

This means the top part of the function should have domain $x < 2$ , and the second part of the function should have domain $x \geq 2$ .

This eliminates everything except for B.

First plug in f and g:
$3 x^{2} +1- [1-x]$
Then distribute $3 x^{2} +1-1+x$
Combine like terms
$3 x^{2} +x$
Now plug in 2 for x
$3( 2^{2} )+2$
3(4)+2=12+2=14

Hope that helps

Find the first five terms of the sequence: an = 5an – 1 + 2; a1 = 3.

pishuonlain [190]

Given that the series is given by:
an=5an-1+2
where:
a1=3
then the other terms of the sequence will be:
a2=5a1+2
a2=5*3+2=17

a3=5a2+2
a3=5(17)+2
a3=87

a4=5a3+2
a4=5(87)+2
a4=437

a5=5a4+2
a5=(5*437+2)
a5=2187

hence the sequence will be:
<span>3, 17, 87, 437, 2187
</span>
Answer: <span>a) {3, 17, 87, 437, 2187}</span>

Sin(A+B-C) find the equation

Nezavi [6.7K]

Answer:

[SInA][CosB][CosC] + [CosA][SinB][CosC] - [CosA][CosB][SinC] - [SinA][SinB][SinC]

Step-by-step explanation:

Given:

Sin (A + B - C)

Find;

Expansion of given expression

Computation:

Sin (A + B - C)

Sin [(A + B) - C]

Sin(A + B)CosC - Cos(A + B)SinC

[SInACosB + CosASinB]CosC - [CosACosB - SinASinB]SinC

SInACosBCosC + CosASinBCosC - CosACosBSinC - SinASinBSinC

[SInA][CosB][CosC] + [CosA][SinB][CosC] - [CosA][CosB][SinC] - [SinA][SinB][SinC]
