Answer =124
4+8+16+32+64=124
I hope this helped! :)
Answer:
a = 3
b = -9
c = -3
d = 22
e = 49 - 9
f = a^2 -3
Step-by-step explanation:
Please no more questions :(
It is decreasing at B. (ln9/3,∞)
The mode is the score that she scored most frequently. All the scores where attained once except 80, thus 80 is the mode.
Answer:
1. There will be two roots not only one
2.a( +16) =0
Step-by-step explanation:
Simply assume a quadratic equation
Here a,b,c are real independent variables.
As given by student -4i is one of it's root it must satisfy the equation.
-16a +4ib+c=0
b must be zero otherwise either a or c must be imaginary number which is not possible.
So b =0
then, c= 16a
a+c=a+16a
Quadratic is a( +16) =0 here a is any real number.
