Answer:
Option D. 10,779 feet
Step-by-step explanation:
Given from the figure attached,
PT = OB = 7000 ft
PB = OT = x feet
and angle of elevation (∠POT) = 30°
By applying Tan rule in the triangle POT,
tan33° =
= 
tan33° = 
x = 
x = 10779 feet
Therefore, distance between the bird (B) and plane (P) is 10,779 feet.
Option D. will be the answer.
Answer:
D: k*x=y
Step-by-step explanation:
a proportional relationship is basically a linear equation (y=mx+b)
Answer:

Step-by-step explanation:
cannot be factorised in the form (x+b)(x-b) unless one of the b's is zero, so I wonder if the expression is incomplete?
To factorise
, take out the common factor
:

Therefore, x = 0 and x = 4
- - - - - - - - -
factorised in the form (x+b)(x-b) would be 
but it is not usual to have a zero in a factorised form.
X² + ((1.5x + 3) - 3)² = 16
<span>x² + (1.5x)² = 16 </span>
<span>x² + 2.25x² = 16 </span>
<span>3.25x² = 16 </span>
<span>x = 8√(13)/13 </span>
<span>x ≈ 2.219 </span>
<span>and so </span>
<span>y = 1.5(8√(13)/13)+ 3 </span>
<span> ≈ 6.328 </span>
<span>so </span>
<span>(2.219, 6.328) </span>
