Answer:
A
Step-by-step explanation:
By the Law of Sines,
- (sin A)/(11)=(sin 30°)/18
- sin A = (11 sin 30°)/18
- A = arcsin((11 sin 30°)/18), which is about 17.8 degrees.
F '(x<span>) = </span>2(3x2<span> + 5) + 6x(</span>2x<span> - </span>1<span>) ... + </span>3), s(x<span>) = </span>x<span> - 4. Use the </span>product<span> rule table. below to get: r'(</span>x) = 20x + 11. s'(x<span>) = </span>1<span> ... f'(</span>x) = (x<span> - 4</span>)(20x + 11) - (5x<span> - </span>2)(2x<span> + </span>3)/(x<span> - 4)</span>2<span>.</span>First, we will distribute 2x<span> to (</span>x<span> + 5), then we will distribute </span>3<span>. ... </span>5x<span>. That is,. multiplying binomials. 6x − </span>x<span>= </span>5x<span>. Example </span>2<span>. Multiply (3x − </span>1)(x<span> + </span>2). Answer. 3x2<span> + </span>5x<span>

Hello!
The answer for A is:
The answer for B is: The rocket will hit the lake surface in 5 seconds.
<h2>Why?</h2>
Defining the terms:
So, replacing it in the quadratic equation (it's given to you in the exercise)\\
We are working with a quadratic equation, so we will have two possible results,
Now, we are asked to find the time, time can not be a negative value, we have to discard X1 (-1) since it's a negative value, knowing that, the rocket will hit the lake after 5 seconds.
Have a nice day!
D. his loan application will be denied. ( and he probably does have a high credit score.) Hope this helps (=^-^=)
