Answer:
35.7 km and 248.3 °
Step-by-step explanation:
I will attach the diagram to an image to make it easier to understand.
We will use the formula corresponding to the law of cosine
y² = 42² + 28² - (2 * 42 * 25 * cos 58 °)
y² = 2389 - 1112.83 = 1276.17
y = √1276.17
y = 35.72 km
Now, to calculate the surveyor's bearing from her base camp we must use the sine law:
[(Sin 58 °) / y] = [(Sin A) / 42]
Without A = (42 * without 58 °) /35.72
A = sin⁻¹ (0.9971)
A = 85.7 °
Bearing of the surveyor from the base camp = 270 ° - (85.7 ° - 64 °) = 248.3 °
Answer:
(-9, -3) - Interval over which the difference of the numbers of sales is negative.
(4.9, 10 ) - Interval over which the difference of the numbers of sales 15 positive
(-3, 10) - Interval over which the difference of the numbers of tale decreasing
(0, 4.9) - Interval over which the difference of the numbers of sales is increasing
Hope this helps!
Louis is wrong as you do the things in the bracket first there for you would do this (5x3+3)2= (15+3)2= (18)2= 18x2 = 36
