Vsevolod [243]3 years ago
6 0

Answer:

A = 78.5 cm^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know r =5 and pi = 3.14

A = 3.14 (5^2)

A = 3.14 (25)

A = 78.5 cm^2

Find the perimeter and area of the figure below.
hichkok12 [17]

Answer:

perimeter = 40

area = 46(unit)^2

Step-by-step explanation:

Perimeter - all sides added together

  1. Find unknown sides (8-3 = 5, 12-2 = 10)
  2. Add all sides together (8+2+5+10+3+12 = 40)

Area - Length multiplied by width

  1. Divide shape into two rectangles (#1 is 2x5 and #2 is 3x12)
  2. Find individual area (rectangle #1: 2*5 = 10 / rectangle #2: 3*12 = 36)
  3. Add areas together (10+36 = 46)
  4. Finish with unit squared (46___^2)

How to determine the longest side of a triangle
Temka [501]
1- Learn the Pythagorean theorem. The Pythagorean theorem describes the relationship between the sides of a right triangle. He states that for any triangle rectangle with sides of length a and b, and hypotenuse of length c, a2 + b2 = c2.

2- First: make sure it's even a rectangle triangle. The Pythagorean theorem only has an effect on triangle rectangles, and by definition, only rectangular triangles have a hypotenuse. If your triangle has an angle with exactly 90 degrees, it is a right triangle, and you can continue.
Straight angles are often noticed in textbooks and academic proofs with a small square at the corner of the angle. This special mark represents the indication "90 degrees".

3- Set the variables a, b, and c to the sides of the triangle. The variable "c" will always represent the hypotenuse, or the side of greater extension. Choose one of the other sides to be a and give the other the denomination b (the order is irrelevant because the result will be the same). Next, enter the lengths of a and b in the formula, according to the following example:
If your triangle has sides of lengths 3 and 4, and you have defined letters to these sides, such as a = 3 and b = 4, you can write the equation as follows: 32 + 42 = c2

Use the function f (x) = 2x^2 – 5.<br><br>(Look at picture)
Akimi4 [234]

Answer:

C

Step-by-step explanation:

By the definition of an inverse function, if:

f(a)=b\text{ then } f^{-1}(b)=a

Therefore, the domain of the original function will be the range of the inverse function.

And the range of the original function will be the domain of the inverse function.

We have the original function:

f(x)=2x^2-5

With the domain:

-\infty

Since the domain of the original function is such, then the range of the inverse function is also the same as above.

So, the range of the inverse function is also:

-\infty< f^{-1}(x)< \infty

So, our answer is

C.

Notes:

A, B, and E would automatically be incorrect since we never use ”or equal to” when using the infinity symbol. This is because we can never “equal” infinity.
