Combine the two sets to form one giant set. If needed, toss out any duplicate values.

So,
A U B = {4,7,10,13,17, 3,5,7,9}

Toss out the duplicate item "7" and sort the values to get

A U B = {3,4,5,7,9,10,13,17}

△ABC is a right isosceles triangle, the centers of two arcs are the midpoint of AB

mel-nik [20]

Answer:

Step-by-step explanation:

Let's define 3 areas:

S = area of semicircle with radius 6 in (diameter AB)
T = area of quarter circle with radius 6√2 in (radius AC)
U = area of triangle ABC (side lengths 6√2)

The white space between the "moon" and the triangle has area ...

white = T - U

Then the area of the "moon" shape is ...

moon = S -white = S -(T -U) = S -T +U

The area we're asked to find is ...

moon - triangle = (S -T +U) -U = S -T

The formula for the area of a circle of radius r is ...

A = πr²

So, ...

S = (1/2)π(6 in)² = 18π in²

and

T = (1/4)π(6√2 in)² = 18π in²

The difference in areas is S -T = (18π in²) -(18π in²) = 0.

There is no difference between the areas of the "moon" and the triangle.

For a moving object the force acting on the object varies directly from the objects acceleration when a force of 25 N acts on a

77julia77 [94]

Answer:

2m/s²

Step-by-step explanation:

If for a moving object the force acting on the object varies directly from the objects acceleration, then it can be expressed as:

F∝a

F = ka.

F is the force

a is the object's acceleration

From the expression;

k is the constant of proportionality

When an initial force of 25 N acts on the object and the acceleration of the object is 5 m/s², then

k = 25/5

k = 5Ns²/m

If the force exchange to 10 N, the acceleration of the object will be gotten using the relationship above

F = ka

Given F = 10N and k = 5Ns²/m

a = F/k = 10/5

a = 2m/s²

The acceleration of the object will be 2m/s²
