Answers

Answer 1
Given :2x²y - 4xy², x = - 1 & y = 1

To Find :Value of the expression

Solution :

2x²y - 4xy²

Substituting the value of x & y,

= 2(- 1)² × 1 - 4(- 1) × 1²

= 2 × 1 × 1 + 4 × 1

= 2 + 4

= 6

Hence, The value of the expression is 6.

Answer:

X=8

Step-by-step explanation:

well, we are trying to find one of the legs of the triangle, using the equation from the Pythagorean Theorem we know that A^2+B^2=C^2

A^2+B^2=C^2, we know that 6^2 times x^2 MUST equal 10^2.

So using the equation, below i show you how to get the value of x.

A^2+B^2=C^2

6^2+B^2=10^2

36+B^2=100

36-36+B^2=100-36

B^2=64

now, B^2 is equal to 64, but we need to find the square root of 64 to get B, or as listed in the question, x.

To save time, ill just tell you, the square root of 64 is 8.

SO

X=8

Use the circular mirror shown.

The mirror has a frame. The diameter of the mirror with the frame is 17 inches. To the nearest hundredth, what is the area of the mirror with the frame? Use
3.14 for
Enter the correct answer in the box.
Hint

Answers

The area of the mirror with the frame is approximately 226.98 in².

What is an area?

An area is a two-dimensional measurement of the extent or size of a surface. It is a mathematical concept used to describe the amount of space inside a closed boundary, usually measured in square units.

the area of a square can be calculated by multiplying the length of one side by itself. The area of a rectangle can be calculated by multiplying its length and width. Similarly, the area of a circle can be calculated by using the formula πr², where "r" is the radius of the circle. Areas can be used to describe the size of physical objects or spaces

The radius of the mirror can be calculated by subtracting the width of the frame from the diameter:

Radius = (17 in / 2) - (1 in / 2) = 8 in

The area of the mirror (including the frame) can be calculated as:

Area = π * (radius + width of frame)²

Area = 3.14 * (8.5 in)²

Area ≈ 226.98 in²

Rounding to the nearest hundredth, the area of the mirror with the frame is approximately 226.98 in².
