atroni [7]

Answer:

I believe the question says "5j + 16 - 12(-9j - 4) - 12j"  I hope I'm correct because I have almost no idea what you typed.

If you did type "5j + 16 - 12(-9j - 4) - 12j" then your answer would be 133j + 52 I believe. You never put how you would like your problem to be solved, so I simplified.

Step-by-step explanation:

Hope this helps.

Rewrite y = -(x + 2)2 – 5 in standard form.
xenn [34]

Answer:

y = - x² - 4x - 9

Step-by-step explanation:

Given

y = - (x + 2)² - 5 ← expand (x + 2)² using FOIL

  = - (x² + 4x + 4) - 5 ← distribute parenthesis by - 1

  = - x² - 4x - 4 - 5 ← collect like terms

   = - x² - 4x - 9 ← in standard form

Suppose P varies directly with q and that P=36 when q=9 . <br> What is the value of P when q=3?
Yuri [45]

Answer:

P=12

Step-by-step explanation:

Since P=36 and q=9, this looks like a ratio of 4:1. So if q=3, multiply that value by 4 to get your answer

If line AD is a tangent to circle B at point C, and m∠ABC = 40º, what is the measure of ∠BAC? 90º  180º   50º   40º
zhenek [66]
We have a line tangent to the circle with center B at point C. We know that the angle formed between the tangent line at the point of intersection to the line extended from that point to the center of the circle is equal to 90°. In the problem, the 90° is for ∠BCA. We also know that the summation of all angles in a triangle is 180°. We have the solution below for the ∠BAC
180°=∠BAC + ∠BCA + ∠ABC
180°=∠BAC + 90° + 40°
∠BAC =50°
The answer is 50°.
