Answer:
B) 0.0625
Step-by-step explanation:
f(x) = k / x
f(x)=0.5 when x = 0.3
f(x) = k / x
0.5 = k / 0.3
Cross product
0.5 * 0.3 = k
k = 0.15
What is f(x) when x = 2.4?
f(x) = k / x
f(x) = 0.15 / 2.4
f(x) = 0.0625
The answer is B) 0.0625
Answer:
8.06
Step-by-step explanation:
Use the Pythagorean theorem:
The hypotenuse is always the slanted side, or c (x in this picture), but the other numbers can be interchanged. Doesn't matter.
Plug the numbers 4 and 7 into the formula.
Now evaluate them to get 
16+49=65
To get c, take the square root of 65

Answer:
m<1= 120
Step-by-step explanation:
1. we know supplementary angles equals 180. the angle 130 is part of a supplementary angle so we can subtract it by 180 to see that missing angle.
2. we also know that all triangles three angles add up to 180. So if we add the number we know 70+50 (50 is from subtracting 130 from 180), Once we find that answer, we subtract it from 180 to find angle 2 which is 60 degrees
3. Last step, angle 2 is part os a supplementary angle in which the two angles add up to 180. So, subtracting 60 from 180 will get you the degree of the angel one which his 120 degrees.
