Answer:

2 a

Step-by-step explanation:

Possible derivation:

d/dx(2 a x + 2 a y)

Differentiate the sum term by term and factor out constants:

= 2 a (d/dx(x)) + d/dx(2 a y)

The derivative of x is 1:

= d/dx(2 a y) + 1 2 a

The derivative of 2 a y is zero:

= 2 a + 0

Simplify the expression:

Answer: 2 a

Simplify (−3 + i) / (7+i)

Kitty [74]

Answer: -2/5+1/5i

Explanation:

complex rule.

(-3*7+1*1)+(1*7-(-3)*1)i/7²+1² ← as the fractions

then refine and rewrite the problem down.

-20+10i/50 ← as the fractions shown.

-20+10i/50=-2+i/5

you can also rewrite the problem down in standard complex form.

-2+i/5=-2/5+1/5i

=-2/5+1/5i

Hope this helps!

Thanks!

Have a great day!

Integral of sin^4 (6x) dx

DENIUS [597]

Hello,

$\boxed{sin^4\ x= \frac{3}{8}- \frac{cos\ 2x}{2}+\frac{sin\ 4x}{8} }\\

Let's assume t=6x \ dt=6\ dx\\

 \int\limits {sin^4\ 6x} \, dx = \frac{1}{6} *\int\limits {sin^4\ t} \, dt \\

= \dfrac{1}{6} *( \frac{3t}{8} - \frac{sin\ 2t}{4} +\frac{sin\ 4t}{32})+C\\

= \dfrac{3x}{8} - \frac{sin\ 12x}{24} +\frac{sin\ 24x}{192} +C

HELP HELP HELP HELP!! WILL GIVE BRAINLY!! Only answer IF YOURE SURE... WILL REPORT LINKS :)

The answer is D.

Explanation: since the -7 is inside with the x it move the graph 7 units to the right (since it’s a negative sign). If it is outside the x it would move the graph up or down depending on if its a negative or positive number
