Establish two right triangles, both with the height of the pole, h.
Call x the distance from the pole to one stake. Then the distance from the other stake to the pole is 6 -x.
Apply Pytagora's equation to both triangles.
1) h^2 = 7^2 - x^2
2) h^2 = 8^2 - (6-x)^2
Eaual 1 to 2
7^2 - x^2 = 8^2 - 6^2 +12x -x^2
12x = 7^2 -8^2 +6^2 = 49 -64 + 36 = 21
x = 1.75
Substitue x-value in 1
h^2 = 49 - (1.75)^2 = 45.94
h = sqrt(45.94) = 6.78
Answer: option d.
Answer:
3000 dollars
Step-by-step explanation:
because 8000 minus 5000 equqls 3000 dollars. write this "the shop had a 3000 dollar change in the sales between the two months"
32x^5/7 This is the answer for that equation.
The answer is 3) 5+r/14
Let's go segment by segment:
<span>"five plus" means addition, so we have 5 +
</span><span>"the quotient of r and 14" is the division result, so sign / must be present: 14/r
</span>
Therefore "five plus the quotient of r and 14" is 5 + 14/r
A polynomial is considered prime if it cannot be factored into the standard linear form, that problem cannot be factored, making it prime
