Answer:
C. -8
Step-by-step explanation:
-2^4 = 16
-2^-1 = -1/2
Answer:
-8
Step-by-step explanation:
Ok so lets first solve the first one:
[tex]-2^{4} = -2 x -2 x -2 x-2=[/tex] [tex]16[/tex]
[tex]x[/tex] represents times if that's confusing.
Ok so I got [tex]16[/tex] b/c if we multiply a negative times a negative we get positive. And there are 4 negatives not 3 not not 5 but 4 so we get positive.
Now second one:
[tex]-2^{-1} = - 0.5[/tex]
Now lets put it together!
[tex]-0.5 x 16=-8[/tex]
Hope this helps :)

What are the explicit and recursive formulas for the sequence 540, 180, 60, 20, ...?
The explicit formula for the sequence,
aₙ = 540(1/3)ⁿ⁻¹.
And the recursive formula for the sequence,
aₙ = aₙ₋₁(1/3).
What is geometric sequence?A unique kind of sequence called a geometric sequence has a constant ratio between every two succeeding terms. This ratio is regarded as one of the geometric sequence's common ratios.
Given:
540, 180, 60, 20, ...
The sequence is a geometric sequence.
First, we find the common ratio.
180/540 = 1/3
60/180 = 1/3
20/60 = 1/3
Hence, 1/3 is the common ratio
r = 1/3
So,
the explicit formula for the sequence,
aₙ = 540(1/3)ⁿ⁻¹.
And the recursive formula for the sequence,
aₙ = aₙ₋₁(1/3)
Therefore, the formulae are given above.

In triangle ABC, DEAC. If AD=12, BD=3, and CE=10, find BE.
Answer:
BE = 2.5
Step-by-step explanation:
Remark
Use triangles ABC and DEB.
Formula
AB/DB = BC / BE
Givens
AB = 15BD = 3BC = 10 + xBE = xSolution
15/3 = (10 + x)/x Cross multiply
15x = 3(10 + x) Remove the brackets
15x = 30 + 3x Subtract 3x from both sides.
15x - 3x = 30 Combine
12x = 30 Divide by 12
x = 30/12
x = 2.5

The question is not complete but i would solve a similar problem
Solution:
Triangles are shapes with three sides and three angles. Types of triangles are scalene, equilateral, isosceles triangles. Two triangles are similar if their corresponding sides have the same ratio and the angles of the two triangles are also equal.
Since the two triangles are similar, the ratio of their sides are equal, hence:
