Step-by-step explanation:
Add all amount of teachers together
14+26 = 40
14:40
Simplified: 7/20 or 7:20
Ratios are just like fractions and can usually be put in this format
Equation in vertex form, y= (-1/4) x² + 4
<u>Step-by-step explanation:</u>
we have the equation,
y = ax² + 4 ( we need to find "a")
Now we have,
2 = a(4)2 + 4
2 = a (8)+ 4
2-4 = 8a
-2= 8a
a= -1/4
Substituting the value of "a" in the equation, we have
y = (-1/4)(x- 0)² + 4 (or) y= (-1/4) x² + 4
The parabola is opens downward. Therefore the vertex is above the x-axis and then the parabola passes through a point below the x-axis.
Equation in vertex form= y= (-1/4) x² + 4
Answer:
x2 - 2x + 4 (remainder 2).
or we could write it as
x2 - 2x + 4 + 2/(x+3)
Step-by-step explanation:
x2 - 2x + 4 <------ quotient.
x + 3 ) x3 + x2 - 2x + 14
x3 + 3x2
-2x^2 - 2x
-2x2 - 6x
4x + 14
4x + 12
2 <--------- remainder

Answer:
Step-by-step explanation:
We would apply the formula for determining simple interest which is
expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 5 years
P = $15,575
R = 21%
Therefore
I = (15575 × 21 × 5)/100
I = 16353.75
Interest paid is $16353.75
Total amount that Sam would have paid for the car would be
16353.75 + 15575. = $31928.75
