Answer:

a_{n} = 8 *0.5^{n-1}

Step-by-step explanation:

First find the common ratio

r = 4/8 = 1/2

and first term is 8

a_n = a_1 * r^(n-1)

a_n = 8 * (1/2)^(n-1)

a_{n} = 8 *0.5^{n-1}

Numbers 15-16 triangles, "Identify similar figures and find missing lengths"
Arisa [49]
15. 
Rectangles A and B are not similar, because 3/2.5 is 1.2, while 5/4.5 is about 1.1. This means that the two rectangles cannot be increased or decreased by any scale factors to equal each other. Rectangles A and C are not similar, because 3/10 is 0.3, while 5/18 is about 2.8. Rectangles B and C, however, are similar, because 2.5/10 is 0.25, and 4.5/18 is 0.25 as well. This means that Rectangle B can be increased using a scale factor of 4 to make it equal to Rectangle C.

16.
Yes. All squares are similar because, by definition, all the sides of a square are the same. This means that there is only one value to consider when finding out whether or not another square is similar to it. All numbers are divisible by another number, even if the quotient is a decimal, meaning that all squares are similar.

Which answer, to the correct number of significant figures, is closest to the true value of the expression: (9.1 x 104 )(1.1 x 1
DIA [1.3K]

Answer : The correct answer is, -13000 g

Explanation :

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

The rule apply for the multiplication and division is :

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

The given expression is:

(9.1\times 10^4)(1.1\times 10^{-5})(\log 10^{-13})(1000)g

As we know that,

\log 10^{-13}=-13

\Rightarrow (9.1\times 10^4)(1.1\times 10^{-5})(-13)(1000)g

\Rightarrow -13013g

True value means, the rounding off the number. So,

\Rightarrow -13000g

Therefore, the correct answer is, -13000 g
