Answer:
The correct answer is option D. 5.7 units
Step-by-step explanation:
It is given a square, Its diagonals meet to form four right angles
<u>To find the value of x</u>
From the figure we can see that the triangle with sides x, x, 8 have angles 45°,45° and 90°
If the angles are 45°,45° and 90° then sides are in the ratio 1 : 1 : √2
Here x : x : 8 = 1 : 1 : √2
Therefore x = 8√2 = 8/1.414 = 5.6577 ≈ 5.7 units
Therefore the correct answer is option D 5.7 units
F(x) = 1/x and g(x) = -10/x
Domain: same: all real numbers other than x=0.
Range: strictly speaking, these 2 functions have the same range: all real numbers other than y=0. But the graph of g(x) = -10/x looks stretched vertically when compared with that of f(x) = 1/x.
Answer:
2
Step-by-step explanation:
448 ÷ 224 = 2
224 ÷ 112 = 2
Hope this helps and have a nice day :)
1)
50 x 0.8 = 40
answer
40 is 80% of 50
2)
0.85 x 52 = 44.2
answer
44.2 is 85% of 52
3)
86 x 100 / 430 = 20%
answer
20% of 430 is 86
