Step-by-step explanation:
f(x) = |x-7| + 3
when x is equal to 4, then
f(4) = |4-7| + 3
=-3+3
=0
Use Pythagaras theorem :-
x^2 = 1.8^2 + 2.4^2 where a is distance required
x^2 = 9
x = 3 miles Answer
If an object has a density of less than
g/ml, the object will float in water.
So, fourth option is correct

The object with density less than
g/ml will float, and the object with a density more than
g/ml will sink.
So, if an object has a density of less than
g/ml, the object will float in water.
Therefore, fourth option is correct
