Answer:7 2/35
Step-by-step explanation:
This is because of pemdas parenthesis exponents multiplication division addition and subtraction
Gcf refers to a digit which can divide both numbers without a remainder
20|50 is divisible by 2 to become 10|25 and then divisible by 5 to become 2|5
=2×5
Gcf= 10

.Find
(i) the height of the tree.
(ii)the width of the river,correct to 2d.p
Answer:
It is not a function.
Step-by-step explanation:
x^2 + y^2 = 4.
Let x = 1:
(1)^2 + y^2 = 4
y^2 = 4 - 1 = 3
So y = √3, -√3.
So we see that for one value of x we get 2 values of y.
So the relation is a one-to-many relation which is not a function.
Functions are either one-to-one or many to-one.
Answer:
(I am assuming that you don't need the answer, but just an explanation of what to do.) Let's take the first problem for an example the first thing you are going to do is subtract 12 on both sides and you will get n> -1 so then you will put a open circle on -1 going to the right.
Hope this helps :)
