Answer: it is less then 5
Step-by-step explanation:
Because 10 lies between two consecutive perfect squares (in increasing order) 10 is located between the square roots of these two numbers. This means that 10 is located between 10 is less than 5.
If the dimensions are tripled then the surface area will increase by a factor of 3^2
That is by 9.
The volume will increase by a factor 3*3 (= 27).
21x³-42x²+12x-1
[area of rectangle =length ×breadth
=(3x2 + 5x - 1)(-7x+1)
=3x²(-7x+1)+5x(-7x+1)-1(-7x+1)
=-21x³+3x²-45x²+5x+7x-1
=-21x³-42x²+12x-1
Answer:
A function assigns only output to each input. A mapping diagram can be used to represent a relationship between input values and output values. ... A mapping diagram represents a function if each input value is paired with only one output value.
