Jia is skipping a rock across a pond. The sequence {4.2, 3.57, 3.0345, 2.5793, …} describes the height of the rock on each succe
mylen [45]

Answer:

u_n=4.2(0.85)^{n-1}

Step-by-step explanation:

u_1=4.2\\u_2=3.57\\u_3=3.0345\\u_4=2.5793

Geometric formula sequence:   u_n=ar^{(n-1)}

(where a is the first term of the sequence and r is the common ratio)

To find the common ratio, divide one of the terms by the previous term:

r=\frac{u_2}{u_1} =\frac{3.57}{4.2} =0.85

From inspection, a=4.2

Therefore, u_n=4.2(0.85)^{n-1}

What is wrong with the following proof that for every integer n, there is an integer k such that n < k < n + 2? Suppose n
expeople1 [14]

Answer:

c)The proof writer mentally assumed the conclusion. He wrote "suppose n is an arbitrary integer", but was really thinking "suppose n is an arbitrary integer, and suppose that for this n, there exists an integer k that satisfies n < k < n+2." Under those assumptions, it follows indeed that k must be n + 1, which justifies the word "therefore": but of course assuming the conclusion destroyed the validity of the proof.

Step-by-step explanation:

when we claim something as a hypothesis we can only conclude with therefore at the end of the proof. so assuming the conclusion nulify the proof from the beginning

How can you solve an equation with the variable on both sides plz help
Sergeeva-Olga [200]
I don't know if this is the right one but i hope this helps. this is how i learned it. 
step 1=get variables on one side oof the equal sign by using inverse operation (add or subtract smaller variable) 
step 2= get constants away from variable to the other side of the equal sign by using inverse operations (add or subtract constant) 
step 3: isolate the variable using inverse operation (multiply or divide)
