"first principle" means "use the limit definition of the derivative":
For f(x) = y = ax² + b, the derivative is
Cost of flakes per ounce is $0.1204 ,
a. If a box cost $77.05 then approximately 640 pounds of flakes are in box.
b. Cost of 2-pound flakes is $3.8525.
As given,
Cost of flakes = $0.1204/ounce
a.
Cost of a box =$77.05
1 pound =16 ounces
$0.1204 =1 ounce
⇒$77.05 =77.05 /0.1204
= 639.95
≈ 640 ounces
= 40 pounds
b. Cost of 2 pounds =(77.05 /40)× 2
= $3.8525
Therefore, there are
a. Approximately 640 pounds of flakes are in box.
b. Cost of 2-pound potato flakes is $3.8525.

set them equal to each other
x²+1=x+1
minus 1 from both sides
x²=x
minus x both sides
x²-x=0
factor
x(x-1)=0
set each to 0
x=0
x-1=0
x=1
subsitute back to find y values
y=x+1, y=0+1, y=1, one point is (0,1)
y=x+1, y=1+1, y=2, another point is (1,2)
the 2 points of intersection are (0,1) and (1,2)
Answer:
Option B. m⁷/n² is the correct answer.
Step-by-step explanation:
Identity,
xᵃ * xᵇ = xᵃ⁺ᵇ
xᵃ/xᵇ = xᵃ⁻ᵇ
x⁻ᵃ = 1/xᵃ
It is given that,
m⁻⁶ n⁻³/m⁻¹³ n⁻¹
Using these three identities we can write,
m⁻⁶ n⁻³/m⁻¹³ n⁻¹ = m⁻⁶ m¹³/n⁻¹n³ (since x⁻ᵃ = 1/xᵃ)
m⁻⁶ m¹³/n⁻¹n³ =m⁽⁻⁶⁺¹³⁾/n⁽⁻¹⁺³⁾ = m⁷/n² (since xᵃ * xᵇ = xᵃ⁺ᵇ and xᵃ/xᵇ = xᵃ⁻ᵇ)
Therefore Option B. m⁷/n² is the correct answer
