⁹P₃=9×8×7=504; ¹⁰C₄=10×9×8×7÷(4×3×2×1)=210.
Answer:
1668 feet.
Step-by-step explanation:
We know the opposite side of the right triangle and we need the adjacent side, so we use the tangent function.
If the distance required is x (adj side) we have:
tan 41 = opp/adj
tan 41 = 1450/x
x = 1450 / tan 41
= 1668.03
<span>2In4x= 2In8
ln(16x^2) = ln64
Multiply e by both sides.
16x^2 = 64
Divide both sides by 16
x^2 = 4
Take the square root of both sides.
x = 2</span>
X/2 + 3 > 9
Subtract 3 from both sides
x/2 > 6
Multiply 2 on both sides
Final Answer: x > 12
