Answer:
5.415m and 2.585m long
Step-by-step explanation:
For a right triangle
hyp^2 = opp^2 + adj^2 (Pythagoras theorem)
Given
hypotenuse = 6m
height(opposite) = h meters
Adjacent = (8-h)m
Substitute into the expression above;
6² = h²+(8-h)²
36 = h²+64-16h+h²
36 = 2h²-16h+64
2h²-16h+64-36 = 0
2h²-16h+28= 0
Divide through by 2
h²-8h+14 = 0
Using the general formula
h = 8±√8²-4(14)/2
h = 8±√64-56/2
h = 8±√8/2
h = 8±2.83/2
h = 8+2.83/2 and 8-2.83/2
h = 10.83/2 and 5.17/2
h = 5.415 and 2.585
hence the length of the height of the right triangle are 5.415m and 2.585m long
⇨ The numeric value of this expression = 12.

Answer: The horizontal asymptote y = 10 means that the final concentration will always be greater than 10%.
Answer:
A
Step-by-step explanation:
The area in step one is
a²+b² but that does not equal (a+b)²
Answer:
b). 11.85
Step-by-step explanation:
The rule is add 0.9
1.95 + 0.9 = 2.85
2.85 + 0.9 = 3.75
3.75 + 0.9 = 4.65...
if you were to add 7 more times you will get to 11.85.
*Here's a trick to make it shorter*
11 × 0.9 = 9.9
9.9 + 1.95 = 11.85
hopefully this helped :3
