Answer:
Step-by-step explanation:
x² - 12x + a = (x + b)²
x² - 12x + a = x² + 2xb + b²
-12 = 2b and a = b²
b = -6
a = b² = 36
It is 2i I standing for imaginary since it is a negative
square root of -1×4
4 square rooted is 2
and a negative number square rooted is i
Answer:
Formula of the slope of the line
m=(y2-y1)/(x2-x1)
y2= -1, y1 = 4
x2=5, x1 = -2
m=(-1-4)/(5-(-2)) = -5/7
Answer is D. slope = -5/7

Respuesta:
28; 33
A (n) = 5n - 2
Explicación paso a paso:
A partir de los datos dados, 3, 8, 13, 18, 23…, podemos ver que cada valor sucesivo de la serie aumenta en 5;
Por lo tanto, los siguientes dos términos de la serie deberían ser:
23 + 5 = 28
28 + 5 = 33
La serie es una progresión aritmética:
Recuerde la fórmula general:
A (norte) = a + (norte - 1) d
Donde, a = Primer término = 3; d = diferencia común = 5
n = enésimo término
A (n) = 3 + (n-1) 5
A (n) = 3 + 5n - 5
A (n) = 5n - 2
Answer:
Step-by-step explanation:
Given problem: C(x,y) = 36x + 48y
constraint: 100x^0.6y^0.4
Using langrange Multiplier,
36 = 0.6(100)x^-0.4y^0.4λ i
48 = 0.4(100)x^0.6y^-0.6λ ii
dividing the equations we have:
x = 2y
substituting into the constraint
p(x,y) = 100 *(2y)^0.6 y^0.4 = 100*2^0.6 *y
5000 = 151.572y
y = 329.876 labor units
x = 659.752 capital units
Minimum cost = 36(659.752) +48(329.876) = $39585.12
