Find the exponential function that satisfies the given conditions: Initial value = 37, increasing at a rate of 5% per year
beks73 [17]

The required function is:

Option 3: f(t) = 37. (1.05)^t

Step-by-step explanation:

The initial value and rate is used to write exponential function

Here

Given

Initial value = 37

Rate = r = 5%

When the rate is 5%, the next year the quantity will be 1+0.05 = 1.05 time of the current quantity.

So,

The function can be written as:

f(t) = 37. (1.05)^t

For initial value, put t=0

f(t) = 37. (1.05)^0\\f(t) = 37 * 1\\f(t) = 37

Hence,

The required function is:

Option 3: f(t) = 37. (1.05)^t

3x-4y;x=4andy=3 evaluate the expression for the indicated values of the variables
neonofarm [45]

Step-by-step explanation:

In this problem, all we have to do is replace x and y with the values we've been given.

It can be helpful to think of 3x as 3 * x (which is the same exact thing), so I'll write it out that way.

3*x - 4*y

(replace)

3*4 - 4*3

(multiply (doing this step first because of PEMDAS))

12 - 12

(subtract)

Anvisha [2.4K]
6.5 because you instantly take $9.50 away from $55. After you get that answer, you will have 45.5. Then divide 45.5 by 7 which will give you 6 and a half hours.

While hovering near the top of Ribbon Falls in Yosemite National Park at 1600 feet, a
ella [17]

Answer:

a)The sunglasses hit the ground at t=0 seconds

b)The maximum height  h(t) = 1600feet

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the polynomial function

                     h(t) = -16 t² + 1600 ...(i)

Differentiating equation (i) with respective to 't' , we get

              \frac{dh}{dt} = -16(2t)+0

Equating zero

             \frac{dh}{dt} = 0

       ⇒ -32t =0

      ⇒   t =0

The sunglasses hit the ground at t=0 seconds

<u><em>Step(ii):-</em></u>

Again differentiating with respective to 't', we get

\frac{d^{2} h}{dt^{2} } = -32(1) = -32

The maximum height at t=0

 h(t) = -16 t² + 1600

 h(t) = 1600feet
