Answer:
f(x) = - 4x + 4
Step-by-step explanation:
Step-by-step explanation:
A linear function has the form
f(x) = ax + b, thus
f(0) = a(0) + b = 4, that is
0 + b = 4 , hence b = 4
f(3) = 3a + b = - 8 ← substitute b = 4
3a + 4 = - 8 ( subtract 4 from both sides )
3a = - 12 ( divide both sides by 3 )
a = - 4, thus
f(x) = - 4x + 4
Answer:
-4400
Step-by-step explanation:
at start of the round I was at -400 so if I answer 8 question of 500 point the points total will be 4000
but as they were incorrect so I get -4000
<em>now</em><em> </em><em>total</em><em> </em><em>points</em><em>=</em><em> </em><em>-</em><em>4</em><em>0</em><em>0</em><em>0</em><em> </em><em>+</em><em> </em><em>(</em><em>-</em><em>4</em><em>0</em><em>0</em><em>)</em><em>=</em><em> </em><em>-</em><em>4</em><em>4</em><em>0</em><em>0</em>

The bird is at a height of 405 feet above the school.

Trigonometric ratio</h3>
Trigonometric ratio is used to show the relationship between the sides and the angles of a right angled triangle.
Let h represent the height of the bird over the school. Hence, using trigonometric ratios:
tan(39) = h / 500
h = 500 * tan(39)
h = 405 feet
The bird is at a height of 405 feet above the school.
