=2m 23m22m =23m−2m =2m 由于它们的值相同,所以选项Ⅰ是等比数列(Geometric Sequences). Ⅱ. 2m2m =2m 3m42m2 =3m22 因此选项 Ⅱ 不是等比数列(Geometric Sequences). Ⅲ. logm2logm =2⋅logmlogm logm4logm2 =4⋅logm2⋅logm =2. 因此选项 Ⅲ 不是等比数列(Geometric Sequences).反馈...
If the sum of the first n terms of a sequence is 6n2−n, which of the following is/are true?( ) Ⅰ. 22 is a term of the sequence. Ⅱ. The 1st term of the sequence is 5. Ⅲ. The sequence is a geometric sequence. 若某数列的首n项之和为6n2−n,则下列何者正确?( ) Ⅰ.22...
Geometric Series: We have a power series with a constant ratio between its successive terms. This is a geometric series. We find the sum of the power series when the ratio has an absolute value less than 1 and the series converges...
What is a geometric transformation? Write down one example of each: a. transformation for stretching /shrinking vertically or horizontally . b. reflection on y-axis. How to do reflections across the x and y axes? Which type of transformation uses a...
Here we look for the sequence in temperature or in pressure of such reservoirs that leads to a minimum in entropy generation and find that in both cases such a sequence is the geometric progression. This work also highlights the close relation between mathematical and physical concepts and is ...
set equal to each other.You may be asked to answer questions that require you to set up a proportion and solve it.The mathematics section will include geometric sequences,which are sequences for which there is a constant ratio between consecutive terms.各位语法达人们,我实在不懂in/for/by……...
The second and fourth terms of a geometric sequence are 2 and 6. Which of the following is a possible first term?( )A.−√3B.−2√33C.−√33D.√3E.3 答案 BLet the first term be a and the common difference be r. Therefore, ar=2(1) and ar3=6(2)Dividing (2) by (1) ...
Which term of the geometric sequence: 2sqrt(3),6,6sqrt(3),…..is 1458? 02:57 The sum of two numbers is 6 times their geometric means, show that nu... 02:19 Which term of the geometric sequence: 2sqrt(3),6,6sqrt(3),…..is 1458? 01:07 Which term of the geometric sequence...
Answer to: Which is larger, the 10th term of an arithmetic sequence that begins with the terms 0 and 100 or the 10th term of a geometric sequence...
It usually consisted of three movements major sections in long instrumental compositions of contrasting tempo—fast/slow/fast—each based on a song or dance form of the time. The suite, written for any combination of instruments, is a sequence or series of movements derived from various European...
