The dollar value v(t) of a certain car model that is t years old is given by the following exponential function. v(t)=27500(0.88

klemol [59]

Answer: Initial value of car = $ 27500

And, the value of car after 13 years is $5219.242

Step-by-step explanation:

Here, the given function that models the price of car after t years,

$v(t) = 27500(0.88)^t$

Since, initially, t = 0

Thus, the initial value of the car,

$v(0) = 27500(0.88)^0=27500$

Now, after 13 years, t = 13

Thus, the value of car after 13 years,

$v(13)=27500(0.88)^{13}$

= $27500\times 0.189790617123$

= $5219.24197088\approx 5219.242$

The required value is $2\times10^9$

Step-by-step explanation:

Weight of ants = $4\times10^{-3}$

Weight of elephant= $8\times10^6$

We need to find, the total weight of about how many ants equals to the weight of an oversized elephant.

The equation given is:

$4\times10^{-3} \times a = 8\times10^6$

We need to find a:

Solving:

$4\times10^{-3} \times a = 8\times10^6\\a=\frac{8\times10^6}{4\times10^{-3}}\\if \,\,10^a/10^-b \,\,then\,\, 10^{a+b}\\a=2\times10^{6+3} \\a=2\times10^9$

So, the required value is $2\times10^9$

Help me plz I don't understand this

KiRa [710]

Answer:

C) 6:1

Step-by-step explanation:

The second number must be a one. To do that, it would have to be multiplied by 4. That means we have to multiply the first number by 4 also:

3/2*4=6

So it’s 6:1

Which values represent the first two terms of the sequence a1=2 and an=-4(an-1)^2?

cricket20 [7]

<span>a1= (which is the first term.)
to find the 2nd term you plug in 2 for (an) in the formula given to you. =-4(2-1)^2 *remember an represents the term u are looking for *
now you start to solve it
-4(2-1)^2
-4 (1)^2 .
-4^2 = 16
so your first two terms are 2 and 16 .</span>
