The equivalent pair of the given expression is; [4.8] and [3.21]

<h3>How to find equivalent pairs?</h3>

Floor function states that the greatest integer that is less than or equal to x. It is represented by:  ⌊ x ⌋.

Ceiling function states that the least integer that is greater than or equal to x. It is represented by ⌈ x ⌉.

Kareem wrote the expressions;

[3.2] [2.7] [2.9] [4.8]

By definition above;

[3.2] = 4

[2.7] = 2

[2.9] = 3

[4.8] = 4

Thus, the equivalent pair is [4.8] and [3.2]

Find the area of the shaded region of circle II below. Round your answer to the nearest tenth if necessary.
gulaghasi [49]

Answer:

63.0

Step-by-step explanation:

area of circle = πr²

area of quarter circle = πr²/4

area of triangle = bh/2

area of shaded quarter circle:

πr²/4 = (3.14159)(7²)/4 = 38.4845 units²

area of shaded triangle:

bh/2 = (7)(7)/2 = 24.5 units²

total shaded area = 38.4845 units² + 24.5 units² = 62.9845 units²

Answer: 63.0 units²

Consider the quadratic function f(x) = –2x2 + 4x – 2. Find the y-intercept and the equation of the axis of symmetry.
Charra [1.4K]

Answer:

see explanation

Step-by-step explanation:

Given

f(x) = - 2x² + 4x - 2

To find the y- intercept set x = 0

f(0) = 0 + 0 - 2 = - 2 ← y- intercept

The equation of the axis of symmetry is of the form x = c

where c is the value of the x- coordinate the line goes through.

Given the equation in standard form

with a = - 2, b = 4 then the axis of symmetry is

x = - \frac{b}{2a} = - \frac{4}{-4} = 1

Equation of axis of symmetry is x = 1
