Answer:
The area of the shaded region is
Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the rectangle minus the area of the circle
The rectangle is a square
so
we have
assume
substitute the values
9514 1404 393
Answer:
(A) -7
Step-by-step explanation:
The function is continuous if you can draw its graph without lifting your pencil. In this case, that means each of the piecewise function definitions must have the same value at x=3.
x^2 +2 = 6x +k . . . . . must be true at x=3
3^2 +2 = 6(3) +k . . . . substitute 3 for x
9 +2 -18 = k . . . . . . . . subtract 18
k = -7 . . . . . . . simplify
Answer: 10a^2 - 25 + 5b
Step-by-step explanation: Only you have to elevate all the numbers and expressions to the potence 2
True is A because 20 is bigger than -20
False is D because -20 IS BIGGER THAN -21
The given shapes area is found to be 132 square feet.
Step-by-step explanation:
Step 1; To determine the area of an indefinite shape we must divide it into the shapes that we know. The shape that is given can be split into a rectangle with a triangle on top of it.
Step 2; To determine the area occupied by a different shape, we must sum the areas of the triangle and the rectangle. The given rectangle measures a length of 11 feet and a width of 9 feet. The area of any given rectangle is the multiplication of its length and width. Area of Rectangle = Length * Width = 11 feet * 9 feet = 99 square feet.
Any given triangles area is half the multiplication of its base value and its height value. In the given diagram, the base of the triangle measures a length of 11 feet (same as the rectangle's length) and the length from base to top is 6 feet (Entire shape's height which is 15 feet - the calculated value of the rectangle's width which is 9).
Area of Triangle = * base * height = * 11 feet * 6 feet = 33 square feet.
Step 3; To find the total area of the shape we must add the areas of the rectangle and the triangle.
Area of given shape = Area of rectangle + Area of Triangle
Area of given shape = 99 square feet + 33 square feet = 132 square feet.
