Answer: 7.7 years
Step-by-step explanation:
Given
The cost of HD TV is $700 and it is decreasing at the rate of 15% per year
After one year it becomes

after 2 year it becomes

Suppose, after x years it becomes $200

Thus, it takes 7.7 years for the cost to come under $200.

Step-by-step explanation:
5 a. 32% of 881 = 281.92
5 b. 39% of 719 = 280.41
6 a. 35% of 441 = 154.35
6 b. 67% of 429 = 287.43
7 a. 21% of 358 = 75.18
7 b. 47% of 6 =2.82
8 a. 67% of 811 = 543.37
8 b.
97% of 311 = 301.67

Answer:
3x^2 (y^5)^1/4 which is the first choice
Explanation:
The fourth root means that the bracket under has the root has a power of 1/4.
So, the given expression is:
(81 * x^8 * y^5)^1/4
Now, we will distribute the power as follows:
(81 * x^8 * y^5)^1/4 = (81)^1/4 * (x^8)^1/4 * (y^5)^1/4
= 3 * x^2 * y^5/4
This expression is equivalent to:
3x^2 (y^5)^1/4 which is the first choice

Step-by-step explanation:
this simply means that the sum of both short segments must be the same as the length of the whole line.
so,
x + 6 + x + 8 = 10
2x + 14 = 10
x + 7 = 5
x = 5 - 7 = -2
