Differentiating Exponential functions In Exercise,find the derivative of the function. See Example 2 and 3.
Lilit [14]

Answer:

5e⁵ˣ

Step-by-step explanation:

Use the implicit differentiation method

let 5x = a

da/dx = 5, da=5dx

y=eᵃ, dy/da=eᵃ

dy/dx=dy/da . da/dx

hence, dy/dx = 5e⁵ˣ

Two types of memberships are available for a theme park:
sergiy2304 [10]

The equation 2v-41=0 can be used to find the number of visits that would make two memberships cost the same amount.

Step-by-step explanation:

Given,

Per month charges of type 1 = $86

Per visit charge = $3

Let,

v be the number of visits.

T(v) = 3v+86    

Per month charges of type 2 = $45

Per visit charge = $5

P(v) = 5v+45

For same amount to be charged;

T(v) = P(v)

3v+86=5v+45\\86-45=5v-3v\\41=2v\\2v-41=0

The equation 2v-41=0 can be used to find the number of visits that would make two memberships cost the same amount.

Use the quadratic formula to solve x2+7x+3. Show all of your work. Then describe the solution.
Mariana [72]

Answer:

Step-by-step explanation:

The coefficients of the quadratic x^2 + 7x + 3 are a = 1, b = 7 and c = 3.

The discriminant is b^2 - 4ac, or 49 - 4(1)(3), or 49-12, or 37.

Because the discriminant is positive, we know that this quadratic equation has two real, different solutions.

      -7 ± √37

x = ---------------   =>   x = (-7 + √37)/2  and  x = (-7 - √37)/2

             2

In words:  This quadratic equation has two real, unequal solutions involving the radicand 37.
