Answer:

  • area of rectangle: 48 cm²
  • area of triangle: 18 cm²
  • shaded area: 30 cm²

Step-by-step explanation:

The area of a rectangle is given by the product of its length and width.

... A = LW

For your rectangle, the overall area is ...

... A = (12 cm)(4 cm) = 48 cm² . . . . rectangle area

___

The area of a triangle is half the product of its base and height. Your triangle is shown with a base of 9 cm, and its height is the height of the rectangle, 4 cm. The triangle area is ...

... A = (1/2)bh

... A = (1/2)(9 cm)(4 cm) = 18 cm² . . . . triangle area

___

The shaded area of the figure is the difference between the rectangle area and the triangle area. (The triangle is fully included in the rectangle, but is not shaded.) That difference is ...

... shaded area = rectangle area - triangle area

... shaded area = 48 cm² - 18 cm² = 30 cm² . . . . shaded area

Which statement is true about the angle bisectors of a triangle?
Rashid [163]

Answer:

Follows are the solution to the given question:

Step-by-step explanation:

There are missing details, which is why its solution is as follows:

When an angle bisector points so, its two sides of the corner are equidistant. Its corner bisector of a triangle angle is a straight line splitting its angle into two congruent directions. In such a single point, calling its incentives, follow three-angle engineers are required of its three triangle angles.

Find the absolute maximum and absolute minimum values of f on the given interval. (If an answer does not exist, enter DNE.)
vodka [1.7K]

Answer:

absolute max is 120 and absolute min is -8

Step-by-step explanation:

Find critical numbers

f'(x) = 3x^2 - 12x + 9 = 0

= 3(x^2 - 4x + 3) = 0

3(x-3)(x-1) = 0

(x-3) = 0 or (x-1)=0

x = 1,3

Test them!

x<1     Sign of f' on this interval is positive

1<x<3 Sign of f' on this interval is negative

x>3    Sign of f' on this interval is positive

f(x) changes from positive to negative at x = 1 which means there is a relative maximum here.

f(x) changes from negative to positive at x = 3 which means there is a relative minimum here.

Test the endpoints to find the absolute max and min.

f(-1) = -8

f(1) = 12

f(3) = 8

f(7) = 120

The absolute maximum value of f is 120 and the absolute minimum value of f is -8.

The area of a triangle is 84.335 in2. The height of the triangle is 8.35 in. To the nearest inch, what is the length of the base
Dmitry_Shevchenko [17]
The formula to find the area of a triangle is:
A = 1/2bh
84.335 = 1/2 b(8.35)
168.67 = 8.35b
20.2 = b.

84.335 = 1/2 (8.35)(20.2)
84.335 = 1/2(168.67)
84.335 = 84.335

The base is 20.2 in.

Hope this helps =)
