First we need to find delta for function ax2+bx+c = 0
DELTA = b2-4ac
DELTA = 25 -( 4*1*5)= 25 - 20 = 5
x1 = (-b-√DELTA)/2a = (-5 - √5)/2
x2 = (-b+√DELTA)/2a (-5+√5)/2
x1 and x2 are zeros of this function
Answer:
45
Step-by-step explanation:
Um, If we say that all the numbers are 44, and now we add 50, then we will get 270. Find the mean of 270. We get 45.
Answer:
Options 1 and 2
Step-by-step explanation:
- Correct. The range of all linear functions without a restricted domain is the set of all real numbers.
- Correct. The range of all linear functions without a restricted domain is the set of all real numbers.
- Wrong. The exponential cannot take negative values.
- Wrong. Quadratics do not have a range that is the set of real numbers.
- Wrong. Quadratics do not have a range that is the set of real numbers.
Answer:
SI=P ×R × T
Step-by-step explanation:
P=$500
R=6%
T=3 years
SI=500×3×6 ÷100
=$90
A) first choice because for x=0 the y= 5 and for x=2 the y=3
