Answer: The area of yellow band is 24x+144 sq. inches.

Step-by-step explanation:

Let the side length of the red square be 'x' inches

Width of the yellow band surrounds the red square = 6 inches

So, Length of  band would be

6+x+6=x+12

Width of  band would be

6+x+6=x+12

So, Area of the yellow band would be

\text{Area of whole band}-\text{Area of red square}\\\\=(x+12)\times (x+12)-x^2\\\\=(x+12)^2-x^2\\\\=x^2+144+24x-x^2\\\\=24x+144

Hence, the area of yellow band is 24x+144 sq. inches.

What is the equation of the line that passes through the points given in the table
Zepler [3.9K]

Answer:

B: y = -2x + 5

Step-by-step explanation:

-2 - 1 = -3

9 - 3 = 6

\frac{6}{-3} = -2

gradient = -2

3 = 1 x -2 + c

3 = -2 + c

5 = c

y intercept = 5

equation = y = -2x + 5

so the answer is option b

Cuatro meses después que se detuviera la publicidad, una compañia fabricante notifica que sus ventas han cai­do de 100.000 unida
Volgvan

Answer:

51,200 unidades

Step-by-step explanation:

Paso 1

Calculamos el porcentaje de disminución

= 100000 - 80000/100000 × 100

= 20000/100000 × 100

= 20%

Por lo tanto, el porcentaje de disminución cada mes = 20%

Paso 2

La fórmula de la disminución exponencial

y = a (1 - r) ^ t

a = 80.000

r = 20% = 0,2

t = tiempo en meses = 2

y = 80000 (1 - 0,2) ^ 2

y = 51.200 unidades

Answer:

Future amount (A) = $1,258.77 (Approx)

Step-by-step explanation:

Given:

Amount deposit (p) = $693

Rate of interest monthly (r) = 4.9% / 12 = 0.003833

Number of month (n) = 13 × 12 = 156

Find:

Future amount (A)

Computation:

A = p [1+r]^n \\\\ A = 693 [1+0.003833]^{156}\\\\ A= 693[1.8163]\\\\ A = 1258.77

Future amount (A) = $1,258.77 (Approx)
