Answer:
Step-by-step explanation:
t2 = a*r
t2 = 6
t5 = a*r^4
t5 = 162
162/6 = ar^4 / ar
r^3 = 27
r = 3
6 = a*3
2 = a
Sum = a(r^n - 1)
=======
r - 1
n = 5
a = 2
r = 3
Sum = 2(3^5 - 1)
=======
2
Sum = 242
Answer:
x = 4
Step-by-step explanation:
The ratio of the side opposite the large filled dot to the hypotenuse is ...
16/20 = x/5
(4/5)(5) = x = 4 . . . . multiply by 5
The value of x is 4.

*see attachment below showing the dot plot and box plot created by Tia
Answer:
Dot plot
Step-by-step explanation:
In a dot plot, the temperature of a day is represented by 1 dot. There are 30 dots on the box plot shown in the attachment that was made by Tia.
This dot plot display makes it easier to find how many days had a temperature that is higher than 15°.
Thus, from the dot plot, we have:
2 dots representing 2 days having a temperature of 16°C each
2 days also have daily temperature of 17°C
2 days have temperature of 18°C as well, and
1 day has temperature of 19° C.
Therefore, the number of days that had a temperature above 15°C is 7 days.
8⊕6 is 10
Step-by-step explanation:
We will use the substitution method to solve this problem
∵ The operation ⊕ is defined by p⊕q = 
∵ You want to find 8⊕6
- Then do these steps:
- Substitute p by 8
- Substitute q by 6
- Calculate the square root of 8² + 6²
∵ p = 8
∴ p² = 8² = 64
∵ q = 6
∴ q² = 6² = 36
∵ p⊕q = 
- Substitute p by 8 and q by 6 in the rule above
∴ 8⊕6 = 
- Substitute 8² by 64 and 6² by 36
∴ 8⊕6 = 
∴ 8⊕6 = 
∵ 
∴ 8⊕6 = 10
8⊕6 is 10
