I’m not entirely sure of the question but the multiples of 9 are
1 9
3 3
and if you are asking for the multiples of 10 those are;
1 10
2 5
is this the answer you were looking for ?
Answer:
2x^2 +11
Step-by-step explanation:
(x) = 3 x^2 + 2
g(x) = x^2 - 9
(f - g)(x) =3 x^2 + 2 - (x^2 - 9)
Distribute the minus sign
= 3x^2 +2 - x^2 +9
Combine like terms
= 2x^2 +11
The slope of y = 3x is 3, and the slope of y = -3x is well, yes, you guessed it, is -3, same value, just different sign, and when that happens the slopes are just mirroring each other, in this case, the mirror line, line of symmetry, is the y-axis, notice in the picture below.
Answer:
22.6 degrees
Step:
The hypotenuse is 13cm using pythagoras theorem.
Now, finding the smallest angle is by using;
SOH
sin = opposite over hypotenuse
Thus, cos^-1 (12/13)
=22.61
and equals to 22.6 (1d.p）
