Answer:

Step-by-step explanation:

a) x = 1.786 & -1.120

Explanation:

Turning points are points where the derivative equals zero. Solving the derivative for the values of X will give the answer to part a.

The derivative of this equation $x^3 =x^2-6x[/t[tex] is [tex]3x^2+2x-6$ .

Solving the equation $3x^2+2x-6=0$ using the quadratic formula we get 1.786 & -1.120

b) x = -3, x=0 and x=2

Explanation:

The solution to this equation are the points where the graph intersects with the x axis. Looking at the graph we can see that these points are -3 , 0 and 2

Hi there
The formula of the future value of annuity ordinary is
Fv=pmt [(1+r/k)^(kn)-1)÷(r/k)]
Fv future value?
PMT monthly payment 608
R interest rate 0.06
K compounded monthly 12
N time 6years
So
Fv=608×(((1+0.06÷12)^(12×6)
−1)÷(0.06÷12))

PLEASE HELP SOLVE FOR Y

alexgriva [62]

Hello!

$\large\boxed{y = 5(\frac{1}{2})^{x} }$

Recall that the equation of an exponential graph is:

$y = a(b)^{x}$

We can see from the graph there is a y-intercept at y = 5. Plugging in 0 for x results in:

$5 = a(b)^{0}\\\\5 = a(1)\\\\a = 5$

Solve for b by plugging in another point on the graph:

$10 = 5(b)^{-1}\\\\2 = b^{-1}\\\\b = 1/2$

Write the final equation:

$y = 5(\frac{1}{2})^{x}$

Pumpkin patch: Suppose we plant pumpkins in a garden where half of the plants are shaded. Then, to test a new fertilizer, we fer

VladimirAG [237]

Answer:

B. Fertilizer.

Step-by-step explanation:

In this experiment, you actually failed to include the fertilizer. This is because you are only fertilizing the pumpkins in the sun and not the shade. Therefore, you really do not know if the pumpkins that grew larger and prettier did so because of the fertilizer or the sun. What you should have done was either fertilized all pumpkins, none of the pumpkins, or half of the ones in the sun and half of the ones in the shade. That way you can correctly isolate the effect of the fertilizer on the pumpkins growth.
