X^2-9x=-8
x^2-9x+8=-8+8
x^2-9x+8=0
(x-8)(x-1)=0
x-8=0
x-8+8=0+8
x=8
x-1=0
x-1+1=0+1
x=1
There are 2 solutions, which are 1 and 8
F(4)= -4-8=-12
F(-2)=-(-2)-8=2-8= -6
F(2)= -2-8=-10
F(0)=0-8=-8
F(-3)= -(-3)-8=3-8=5
Answer:
6 units
Step-by-step explanation:
We require to calculate the absolute value so as to consider the measure both ways, that is
AB = | 1 - (- 5) | = | 1 + 5 | = 6
BA = | - 5 - 1 | = | - 6 | = 6
Keeping in mind the formula for circumference is Pi x Diameter, you simply multiply 45 by pi.
This gives you 141.3716694
