Answer:
Step-by-step explanation:
The diagonal of a square is the same thing as the hypotenuse of a right triangle. This right triangle is a 45-45-90 since the sides are made up of sides of a square which all measure the same length, x.
Using Pythagorean's Theorem,
and
and
and taking the square root of both sides gives us that
which simplifies to
I'm assuming that your teacher has told you about rationalizing the denominator when you've got a radical there, so we will do that by multiplying by 
:
which gives us
Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.
For a moving object, the force acting on the object varies directly with the object's acceleration. Let F represent force and A represent acceleration, if we introduce a constant of variation, k, then the expression becomes
F = kA
When a force of 72 N acts on a certain object, the acceleration of the object is 8 m/s^2. This means that
72 = 8k
k = 72/8 = 9
The equation becomes
F = 9A
If the acceleration of the object becomes 10 m/s^2, then the force would be
F = 9 × 10
F = 90N
