Answer:
Therefore, Option 1 is correct.
Step-by-step explanation:
We have been given the quadratic equation:
If we compare it will general quadratic equation which is: 
Here, a=5,b=3 and c= -4.
Now, we will use the formula:
And then 
Where,
Therefore, Option 1 is correct.
Easy
(g o f)(-5)=g(f(-5))
first evaluate f(-5), then input the result into g(x)
f(-5)=-2(-5)-7
f(-5)=10-7
f(-5)=3
g(3)=-4(3)+6
g(3)=-12+6
g(3)=-6
(g o f)(-5)=-6
Multiply the numerator and denominator by √2
10√2/2
Simplify
5√2
The z-score tells you
the value is 0.02 standard deviations above the mean.
Answer: Mary makes $1160, Steven makes $142.50
Step-by-step explanation:
Facts
MARY
8% commision on everything she sells
She sells a car for $14,500
The first question about Mary asks how much commision she makes. To find that, lets find 8% of 14,500
8% of 14,500= 0.08x14,500= 1160
Therefore, Mary makes $1,160 in commision.
STEVEN
Facts
He makes 15% in commision for the supplies he sells
He sells $950 in supplies
Money made =?
15% of 950=0.15x950=$142.50
