Answer: 5 Explanation- 1: 2x^3; 2: -x^4; 3: 3; 4: -3x^2; 5: 3x
Answer:
Correct answer is 54.82 ft.
Step-by-step explanation:
First of all, let us label the diagram and do the construction as per the attached answer image.
Let us consider
:

Let side AB = d ft and let side BC = x ft
We need to find AB to find the shortest distance across the river.
Using trigonometric identity of tangent:


Now, let us have a look at another right angled triangle ABD:
Let us consider
:

side AB = d ft and side BD = x+75 ft
Using trigonometric identity of tangent:


Correct answer is 54.82 ft.
Answer:
D) y = -2 + 3
Step-by-step explanation:
4x + 2y = 6
<u>Subtrack the x to each side of the equation</u>
2y = -4x + 6
<u>And then you can by 2 on each side of the equation and you can get your answer</u>
y = -2x + 3
Linear, decrease by 2 for every decrease of x.
