The equation is:
20,000 * e^(0.15 t) = 28,000
e^( 0.15 t ) = 28,000 : 20,000
e^( 0.15 t ) = 1.4
0.15 t = ln 1.4
0.15 t = 0.3365
t = 0.3365 : 0.15
t = 2.24 ≈ 2

Reil [10]

Refer to the attached image.

Let the width of the border be 'x' inch.

Area of border = Area of rectangle ABCD - Area of rectangle PQRS

Area of rectangle ABCD = length \times width

= AB \times BC

= (13+2x) \times (9+2x) square units.

Area of rectangle PQRS = PQ \times RQ

= 13 \times 9

= 117 square units.

So, area of border = (13+2x)(9+2x)-117 = 48

As it is given that the area of border is 48 square units.

So, 117+26x+18x+4x^2-117 = 48

44x + 4x^2-48=0

4x^2 + 44x = 48

So, the complete equation is 4x^2 + 44x = 48.

Now, we will find 'x' in the equation x^2+11x-12=0,

x^2 + 12x - x -12 =0

x(x+12)-1(x+12)=0

(x-1) (x+12)=0

So, x = 1 or x = -12

Width can'not be negative.

So, x = 1 .

Therefore, the width of the border can'not be 2.5 inch.

Therefore, the width of the border is 1 inch.

Which expression is equivalent to 3^4 x 3^-9?
serious [3.7K]
1/3^5

When multiplying exponents you just add them. X^a x X^b = X^a+b

If you have a negative exponent, you flip it to be the denominator (if originally numerator) or numerator (if originally denominator.

So, 3^-5 = 1/3^5
