<u>Answer</u>:

x = 70 ; 

y = 50  .
_____________________________________________________
Explanation:
_____________________________________________________
y = 50 ; since vertical angles are congruent.


180 – (50 + 60) = x ;  since all angles in any triangle add up to 180 degrees. 

↔  x = 180 – (50 + 60) = 180 – (110) = 70.

F(x) = ( - 3x² + 2 – 2)e". Find f'(x) and f''(x).<br> f'(2) =<br> f''(c)<br> =
prisoha [69]

Answer:

-3x²-5xeˣ-eˣ

-3eˣx²-11eˣx-6eˣ

Step-by-step explanation:

I'm going to go by the picture and not what you wrote in your title.

To find the derivative of this we have to apply the product rule

(a*b)'=

a'*b+a*b'

We plug in our numbers and get

(-3x²+x-2)'*eˣ+(-3x²+x-2)*eˣ'

Now we can evaluate the derivatives and simplify

(-3x²+x-2)'= -6x+1

eˣ'=eˣ

which means we have

(-6x+1)*eˣ+(-3x²+x-2)*eˣ

Simplify

-6xeˣ+eˣ-3x²eˣ+xeˣ-2eˣ

Combine like terms

-3x²eˣ-5xeˣ-eˣ

Now we just need to find the derivative of this

We can apply the same product rule as we did before

(-3x²eˣ)'

Let's start by factoring out the -3 to get

-3(x²eˣ)'

which is equal to

-3(x²eˣ'+x²'eˣ)

Compute this and get

-3(x²eˣ+2xeˣ)= -3x²eˣ-6xeˣ

Now let's find the derivative of the second part

(-5xeˣ)'

-5(x'eˣ+xeˣ')

-5(eˣ+xeˣ)

-5eˣ-5xeˣ

Which means we have

(-3x²eˣ-6xeˣ)+(-5eˣ-5xeˣ)-eˣ

Combine like terms and get

-3eˣx²-11eˣx-6eˣ

Lisa drove 819 miles 13 hours. At the same rate, how long would it take her to drive 504 miles?
Damm [24]

Answer:

The answer is

<h2>8 hours</h2>

Step-by-step explanation:

To solve this question we use ratio and proportion

From the question

Lisa drove 819 miles for 13 hours

If for Lisa drove 819 miles for 13 hours

Then for 504 miles she will drive

<h2>\frac{504  \times  13}{819}  =  \frac{6552}{819}</h2>

We have the final answer as

<h3>8 hours</h3>

Hope this helps you

Write a linear equation in standard form that crosses (4,-3) and (-2,9)
Goryan [66]
Y = -2x + 5 
That's the answer and you find it by finding the slope by using (4,-3) and (-2,9). You subtract -3 from 9 over 4 from -2. After you find the slope which would be -2 you use the equation y-y1 = slope(x - x1). You plug in any coordinates and find the answer.
