Answer:
The first choice is correct.
Step-by-step explanation:
First work out the common ratio r:-
a2 = a1r and a5 = a1 r^4
So r^3 = a1r^4 / a1r = 256/ 108
r = cube root (256/-108) = 4/3
So the explicit formula is 108(4/3)^(n-1)
Answer:
A) 20°
Step-by-step explanation:
Sine and cosine are co-function complements which means that value of sine of an angle is equal to the value of cosine of the complementary angles.
This can be represented by:


Given statement:

Applying co-function complements

Since, we can represent 70° = 90°-20°
So
Thus,
makes the statement true.
Create a stem-and-leaf plot of the data values 72,44,75,57,81,65,68,72,73,84,91,76,83,88.
n200080 [17]
To solve this problem you must apply the problem you must apply the proccedure shown below:
1. You have the following data values given in the problem above:
<span>72,44,75,57,81,65,68,72,73,84,91,76,83,88.
2. To create a stem and leaf plot, you must order the digits in the following way:
- The first digits must be listed in the colum "Stem".
- The second digit must be listed in the colum "Leaf".
- Then, write the key, which is the meaning of the data ploted (4|4 means 44).
The S</span>
tem and leaf plot is shown in the figure attached.
