Hey Luckycharms1233, 

Lets find the product of your equation together, 
<span>
          Lets simplify this step by step, shall we. 

</span>We want to find the derivative\:of\:F\left(x\right)=-x^2-x+2. 

\dfrac{d}{dx}\left(-x^2-x+2\right) 

Now we have to \mathrm{Apply\:the\:Sum/Difference\:Rule}:\quad \left(f\pm g\right)^'=f^'\pm g^'. 

This leads to : -\frac{d}{dx}\left(x^2\right)-\frac{d}{dx}\left(x\right)+\frac{d}{dx}\left(2\right). 

        Now we simplify. 

\dfrac{d}{dx}\left(x^2\right)=2x 

\dfrac{d}{dx}\left(x\right)=1 

\dfrac{d}{dx}\left(2\right)=0 

     Finally we arrive at : -2x-1+0 

This can be simplified to -2x-1 

          Our graph should look like the one below 

Hope this helps,

Find the nth term of this quadratic sequence<br>4,9, 16, 25, 36,​
hoa [83]

Answer:

a_{n} = (n + 1)²

Step-by-step explanation:

The terms are square numbers with each term shifted to the right by 1

That is 1, 4, 9, 16, 25, 36, .....

Thus to obtain 4 in the first position, then

n = 1 → (1 + 1)² = 2² = 4

To obtain any term add 1 to its position in the sequence, that is

a_{n} = (n + 1)²

georgia drew a scale model of one of the stepping stones in her garden. the two shapes are similar, and the ratio of the lengths
Maslowich

The length of the UT is 3 inches if the ratio of the lengths of the sides is 4:1. if the length of side DC equals 12 inches,

<h3>What is a scale factor?</h3>

The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

We have:

Georgia drew a scale model of one of the stepping stones in her garden. the two shapes are similar, and the ratio of the lengths of the sides is 4:1.

The length DC = 12 inches

DC/UT = 4/1

12/UT = 4/1

UT = 12/4 = 3 inches

Thus, the length of the UT is 3 inches if the ratio of the lengths of the sides is 4:1. if the length of side DC equals 12 inches,

Find a formula for the inverse of the function. f(x) = e^6x − 9
STatiana [176]

Answer:

f^{-1}(x)=\frac{1}{6}\ln(x+9)

Step-by-step explanation:

So we have the function:

f(x)=e^{6x}-9

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

x=e^{6f^{-1}(x)}-9

Add 9 to both sides:

x+9=e^{6f^{-1}(x)}

Take the natural log of both sides:

\ln(x+9)=\ln(e^{6f^{-1}(x)})

The right side cancels:

\ln(x+9)=6f^{-1}(x)

Divide both sides by 6:

f^{-1}(x)=\frac{1}{6}\ln(x+9)

And we're done!
