Just differentiate <em>G</em> and <em>H</em> :
• d<em>G</em>/d<em>x</em> = d(<em>x</em> ² <em>eˣ </em>)/d<em>x</em> = 2<em>x</em> <em>eˣ</em> + <em>x</em> ² <em>eˣ</em>
so <em>G</em> is not an antiderivative of <em>f</em>.
• d<em>H</em>/d<em>x</em> = d(2<em>x</em> <em>eˣ</em> - 2<em>eˣ</em> ) = (2<em>eˣ</em> + 2<em>x</em> <em>eˣ</em> ) - 2<em>eˣ</em> = 2<em>x</em> <em>eˣ</em> = <em>f(x)</em>
so <em>H</em> is indeed an antiderivative of <em>f</em>.
Answer:
Step-by-step explanation:
4 quarts=1 gallon
1 quart=1/4 gallon
6 quarts 1/4×6=6/4 gallons=3/2 gallons =1 1/2 gallons
or we can say 4 quarts=1 gallon
2 quarts=1/2 gallon
(4+2=6)quarts=(1+1/2)=1 1/2 gallon.
<span>(x-h)^2 + (y-k)^2 = r^2
</span><span>where r is the radius of the circle, </span>
<span>and h,k are the coordinates of its center;
( x - 8 )^2 + ( y - ( - 2 ) )^2 = 1 ^2 ;
r = 1 ;
h = 8 ; k = - 2.</span>
Ok like what kind of math problems
Answer:
(x-3)^2+(y+2)^2=16
Step-by-step explanation:
center (h,k) radius r
(x-h)^2+(y-k)^2=r^2
