Answer:B
Step-by-step explanation:
4x2 =121
4x2-121=0
using the general formula
[-b( +/-) √b2-4ac]/2a
a=4, b= 0, c=-121
x= [0 ( +/-)√02-(4*4*-121)]/2.4
= ( +/-)√1936)/8 = ( +/-)5.5
x =5.5
x = -5.5
C. Because it equals to the degrees to the 3.7 radians
Answer:
y = 1/2x +5
Step-by-step explanation:
change f(x) to y
y = 2x - 10
then switch x and y
x = 2y - 10
then solve for y
add 10 to both sides and divide both sides by 2
Answer:21 members
Step-by-step explanation:
