B is related to the last term of trinomial
Last term on the left hand side of the equation = Last term on the right hand side of the equation.
The last term on the right hand side is gotten by multiplying all the terms on the right of the two expression.
-32y²= 2*-8y*By
-32y² = -16By² Compare both
32 = 16B
16B = 32
B = 32/16
B = 2.
Answer: first graph is F(x) = 0.5(x-6) (x+2)
Second graph f(x) = (x - 3) ( x + 1 )
Third graph f(x) = -2(x - 1) (x + 3 )
Step-by-step explanation:
Type functions into Desmos graphing calculator and it will plot the points for you.
PLATO
Here,
Time: 4 years
Rate: 5%
Simple interest:500$
So, principal:?
We know,
SI=P*T*R/100
500=P*4*5/100
500=20P/100
20P=50000
P=50000/20
P=2500$
So 2500$ is needed to make atleast 500$ interest in 4 years with 5% rate
