Answer:
Step-by-step explanation:
b:g:c:r = 20:60:15:25 = 4:12:3:5
b:c = 4:3
Let us try A
If we put x = -3 , then y= 27-36+3+1=-5 , thus it us not the polynomial of given points
Now moving onto B
If x = -3, then y =-81-27+36-3-1=76
If x= -1 , then y=-1-1+4-1-1=0
If x =0, then y=-0-0+0-0-1=-1
If x =1, then y= -1+1+4+1-1=4
Thus it is also not the polynomial with given point.
Now onto c
x= -3 , y=81+27-36+3+1=76
x=0, y = 0+0+0+0+1=1
x= -1 , y = 1+1-4+1+1=0
x=1 , y= 1-1-4-1+1=-4
x=2, y=16-8-16-2+1=-9
Hence C is the polynomial of given points
Answer: the club will receive $1500 interest for the year
Step-by-step explanation:
Simple interest is calculated by principal ×rate× time
=$50,000× 3%×1year
50,000×0.03×1
=$1,500
Answer:
n= 85/12
Step-by-step explanation:
Solve by distributing then simplify the arithmetic
it will be 12n - 75 = 13
Add 75 to both sides then Simplify the arithmetic
It will be 12n = 13 + 72 which is 12n = 85
Divide both sides by 12 then Simplify the fraction
it will be like that
12n/12 = 85 / 12
which will equal n = 85/12
Hope it helps! ^w^
