Answer:
Rate of change is increase of 51 followers per year.
Step-by-step explanation:
Given:
Number of followers in 2012 = 74
Number of followers in 2015 = 227
Therefore, increase in followers = 227 - 74 = 153
Duration for the change = 2015 - 2012 = 3 years
Rate of change of followers is given as:
Therefore, rate of change is increase of 51 followers per year.

Answer:
21 inches
Step-by-step explanation:
In 1 rotation the angle at the centre = 360°
For 120° the fraction turned = = , thus
distance travelled = × 63 = 21 inches
The question is about types and number of soultions so you must use b^2-4ac which is the experssion under the root in the quadratic formula
so
if
b^2-4ac=0 then there is one real soultion
if
b^2-4ac<0 then there are two imaginary soultions that differ in the sign between them
if
b^2-4ac>0 then there are two real soultions
so a polynomial is written in the form
ax^2+bx+c=0
so a=-4
b=-4
c=-1
so b^2-4ac=16-16=0
so one real soultion is the answer you are looking
type:real
number:1
