What is the circumference of a circle with the radius of 8.2 (round to the nearest hundredth)?
Answers
C=2piR. C=2(3.14)(8.2). C=6.28(8.2). C= 51.496. But we have to round to the nearest hundredth which is the second place to the right of a decimal. So now C=51.50 (since 49+1=50) :) hope this helps
Which of the following is a solution of 4x2 = − 9x − 4?
Answers
get all on one side add 9x+4 both sides 4x^2+9x+4=0 use quadratic formula in form ax^2+bx+c=0 x=
a=4 b=9 c=4
x= x= x= x= or
aprox x=-1.64039 or -0.6096
4 x 2 = − 9x − 4
Multiply 4 and 2. Add 4 to both sides. 8 + 4 = -9x
Divide both sides by -9. (8 + 4)/-9 = x
Simplify -12/9 = x
