Answer: A, B, D

A, B, and D are equations because an equation has an equal sign that connects two expressions together (i.e., equations have equal signs). In this case, only A, B, and D have equal signs.

D/dx 3^x= Find the derivative

gregori [183]

Differentiate using the exponential rule, which determines that $\bf{\frac{d}{dx}[a^{x}] }$ is $\bf{a^{x} \ In(a) }$ when a=3.

$\boldsymbol{ 3^{x} \ In(3) \ \to \ \ \ Answer }$

Therefore, the correct option is "E". You just have to remove the parentheses.

What are the solutions of |x+6| greater than or equal to 5? Write the solutions as either the union or the intersection of two s

sukhopar [10]

We have that
 |x+6| >= 5
step 1
resolve for (x+6)>=5------> x>=5-6-------> x>= -1
the solution is the interval (-1, ∞)

step 2
resolve for -(x+6) >=5------> -x-6 >=5----> -x >= 5+6---> -x>=11----> x<=-11
the solution is the interval (-∞, -11)

using a graph tool
see the attached figure

the solution is the interval (-∞, -11) ∩ (-1, ∞)
