Answer:
21x^2-2x+1
Step-by-step explanation:
The area of shaded region= The area of the floor - area of the identical islands
The area of shaded region=(5x+1)^2-2*(2x)(x+3)=25x^2+1+10x-4x^2-12x=21x^2-2x+1
1. the total of an area under the curve must be equal to one. 2. Every point of the curve must have an vertical height that is 0 or greater.
Answer:
12.53 miles
Step-by-step explanation:
6² + 11² = x²
36 + 121 = x²
157 = x²
x = 12.53 miles
They throw out the records they no longer need or seen unnecessary because they no longer see the importance of having it.
It's the second choice. We have the parent graph of the absolute value function moved down only, not side to side. So there is no x movement to be indicated inside the absolute value symbols along with the x. When a function moves down, it is indicated by a negative in front of the number. Our parent graph [absolute value of x] is moved down by 2.5 so we have [abs.value x] - 2.5
