El precio de cada acción de una empresa de tecnología ha presentado a través del tiempo un comportamiento dado por la siguiente

función:
Donde t es el tiempo dado en días y A es el precio de la acción inicial cuando t = 0. Un inversionista desea conocer el número de días para el cual el valor de la acción se duplica. Para conocer este resultado, el proceso que se debe realizar es reemplazar f(t) por


A.
A/2, luego, expresar la ecuación en forma de logaritmo natural y ahora despejar t.

B.
2A, luego, expresar la ecuación en forma de logaritmo natural y ahora despejar t.

C.
2A, luego, dividir ambos lados de la ecuación por e y ahora despejar t.

Can someone please help me with this question ?

Answer:

  1350 square inches

Step-by-step explanation:

The area of the end trapezoid is ...

  A = (1/2)(b1 +b2)h = (1/2)(12 +36)(5) = 120 . . . . . square inches

The perimeter of the end trapezoid is ...

  P = 13 +12 +13 + 3×12 = 74 . . . . inches

so the total area of the rectangular surfaces (including the bottom) is ...

  (74 in)(15 in) = 1110 in²

The total area of the ramp is this rectangular area plus the two trapezoidal ends:

  total area = rectangle area + 2×trapezoid area

  = 1110 in² +2×120 in²

  total area = 1350 square inches

Can you help me solve for y ?? Please show your work !! Thank you.
Nadusha1986 [10]

Answer:

y = -3x - 4

Step-by-step explanation:

x - y - 2 = 4x + 2

x - y - 2 + y = 4x + 2 + y

x - 2 = 4x + 2 + y

x - 2 - 4x - 2 = 4x + 2 + y - 4x - 2

-3x - 4 = y

so y = -3x - 4

Infinite over E n=1 4(0.5)^n-1
yan [13]

Answer:

S = 8

Step-by-step explanation:

An infinite geometric series is defined as limit of partial sum of geometric sequences. Therefore, to find the infinite sum, we have to find the partial sum first then input limit approaches infinity.

However, fortunately, the infinite geometric series has already set up for you. It’s got the formula for itself which is:

\displaystyle \large{\lim_{n\to \infty} S_n = \dfrac{a_1}{1-r}}

We can also write in summation notation rather S-term as:

\displaystyle \large{\sum_{n=1}^\infty a_1r^{n-1} = \dfrac{a_1}{1-r}}

Keep in mind that these only work for when |r| < 1 or else it will diverge.

Also, how fortunately, the given summation fits the formula pattern so we do not have to do anything but simply apply the formula in.

\displaystyle \large{\sum_{n=1}^\infty 4(0.5)^{n-1} = \dfrac{4}{1-0.5}}\\\\\displaystyle \large{\sum_{n=1}^\infty 4(0.5)^{n-1} = \dfrac{4}{0.5}}\\\\\displaystyle \large{\sum_{n=1}^\infty 4(0.5)^{n-1} = 8}

Therefore, the sum will converge to 8.

Please let me know if you have any questions!

Please help, will mark brainliest<br><br>50 points
liraira [26]

Answer:

(-6,8)

Step-by-step explanation:

2x + 9y = 60

-9x + y = 62 --> y = 9x + 62 --> 2x + 9(9x + 62) = 60 -->

2x+ 81x + 558 = 60 -->

83x + 558 = 60 -->

83x = -498 -->

x = -6 -->

y = 9(-6) + 62 -->

y = 8
