Answer:
The statement represents the IDENTITY PROPERTY OF ADDITION.
Step-by-step explanation:
Here, the given expression is 8 + 0 = 8
IDENTITY ELEMENT : Identity element is a special type of element in a given set of system, such that any number remains UNALTERED if operated with the identity element.
⇒ a + X = X for, a ≡ IDENTITY ELEMENT
Now, 8 + 0 = 8
Comparing it with the above equation , we get
0 ≡ IDENTITY ELEMENT in the given Binary operation of Addition.
Hence, the statement represent the IDENTITY PROPERTY OF ADDITION.
Easy
set to zero
those are the roots or xintersepts
(x+1)(x+4)(x-7)=0
x+1=0
x=-1
x+4=0
x=-4
x-7=0
x=7
xints are (-4,0) (-1,0) (7,0)
Answer:
The perimeter is 43.6 cm
Step-by-step explanation:
In this question, we are tasked with calculating the perimeter of the sector.
Firstly, we define what a sector is. A sector is part of a circle which is is blinded by two radii and an arc. Hence we say a sector contains two radii.
Thus, to calculate the perimeter of the sector, we need the length of the arc added to 2 * length of the radius
Let’s calculate the length of the arc.
Mathematically, this is theta/360 * 2 * pi * r
where theta is the angle subtended at the middle of the circle which is 135 according to the question, and our radius is 10cm
Thus, we have
135/360 * 2 * 22/7 * 10 = 23.57 cm
Adding two radii to this, we have;
23.57 + 2(10)
= 23.57 + 20 = 43.57 = 43.6 cm to 1 decimal place
