Answer:
5√2 is as simple as it gets
5√2 ≈ 7.071068
Step-by-step explanation:
One simplifies radical expressions by removing from under the radical any squares that might be there. 2 is a prime number, so has no square factors. The simplest form of this radical expression is the one given:
5√2
Your calculator can tell you the value of this irrational number is about ...
5√2 ≈ 7.071068
Answer:
The oranges cost $2.00 apiece, and the apples cost $0.50 apiece. Your equation would be 0.5x+2y= price.
Step-by-step explanation:
17] The distance, x, between the farmhouse and water tower will be given by:
Tan θ=opposite/adjacent
adjacent=opposite/tan θ
thus:
x=500/tan 12-500/tan 16
x=500/0.2126-500/0.2868
x=608.61 yd
~609 yd
Answer: D] about 609 yd
18] The angle of depression will be:
tan θ=opposite/adjacent
thus
tan θ=0.5/13
tan θ=0.0385
θ=arctan 0.0385
θ=2.2°
19] This will be evaluated like #17 above.
Tan θ=opposite/adjacent
adjacent=opposite/tan θ
thus
x=95/tan 31-95/tan42
x=95/0.6009-95/0.9004
x=52.598
~53
answer: A] about 53
20] The horizontal length will be calculated as follows:
sin θ=opposite/hypotenuse
opposite=73 m
hypotenuse=177 m
thus
sinθ=73/177
sinθ=0.4124
θ=arcsin 0.4124
θ=24.357~24.4°
Answer: D]24.4°
The answer is B. A reflection across the x-axis.
The missing angle is 50. 40 + 90 = 130. 180 - 130 = 50.
