The answer is B. When you cross multiply it, it doesn't make sense like the rest of them;
A. 1x24= 24
4x6=24
24=24
B. 4x10=40
7x7=49
40 ≠ 49
C. 16x3=48
24x2=48
48=48
D. 36x5=180
10x18=180
180=180
39 whatevers is how far it flys in a hour
<em>Substitute x = 2 as we get</em>
<em>f(2) = -4(2)+4 = -8+4 = -4</em>
<em>Therefore, f(2) = -4</em>
Answer:
x ≈ 10.7 ft.
Step-by-step explanation:
Given triangle in the picture is a right triangle.
By applying Pythagoras Theorem in this triangle.
(Hypotenuse)² = (Leg 1)² + (Leg2)²
(14)² = x² + 9²
x² = (14)² - 9²


x = 10.72
x ≈ 10.7 ft.
