Which of the following are arithmetic sequences? check all that apply. a. 0.3, 0.6, 0.9, 1.2, 1.5, b. 2, 3, 6, 11, 18, c. 150, 147, 144, 142, d. 2, 4, 9, 16, 25,

Only A

Step-by-step explanation:

A. This is the arithmetic sequence, because

The first term of this sequence is and the difference is 0.3.

B. Since this is not arithmetic sequence.

C. Since this is not arithmetic sequence.

D. Since this is not arithmetic sequence.

Only A

Step-by-step explanation:

A. This is the arithmetic sequence, because

Step-by-step explanation:

the solution is h=10 because you add 9 to each side of the equation.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x
