If you would like to evaluate function h(x) = x^4 + 2 * a^2 + 4 when x = 3a, you can do this using the following steps:
x = 3a
<span>h(x) = x^4 + 2 * a^2 + 4
</span>h(3a) = (3a)^4 + 2 * a^2 + 4 = 3^4 * a^4 + <span>2 * a^2 + 4 = 81 * a^4 + 2 * a^2 + 4
The correct result would be </span>h(3a) = <span>81 * a^4 + 2 * a^2 + 4.</span>
Answer:
Step-by-step explanation:
x=√(5+2√6)/(5-2√6)
x²(x-10)²=1
substitute the value of x in the equation
[√(5+2√6)/(5-2√6)]²(√(5+2√6)/(5-2√6) -10)²=
solve :
(49+20√6)(49-20√6)=1 multiply
1=1 proved
Answer:
108 are singing along
Step-by-step explanation:
Since theres 5 not singing a long for every 3 just divide 180 by 5 which gets you to 36 then times that by 3
Step-by-step explanation:
you do 6 subtract by -2 and should get 8 as your ans8
Look carefully at the first pair: (−3, 9), (−3, −5) Note that x does not change, tho' y does. This is how we recognize a vertical line (whose slope is undefined). The equation of this vertical line is x = -3.
Looking at the second pair: from (3,4) to (5,6), x increases by 2 and y by 2; thus, the slope is m = rise/run = 2/2 = 1.
Third pair: as was the case with the first pair, x does not change here, and thus the equation of this (vertical) line is x=0 (which is the y-axis). The slope is undefined.
