Answer:
- C. negative linear association
Step-by-step explanation:
<u>We have ordered pairs:</u>
- (1, 32), (2, 26), (3, 20), (4, 14), (5, 8)
<u>Looking at the sequence of y-values:</u>
We see it is the arithmetic progression with common difference of -6.
It means the function representing this relationship is linear.
Correct option is C.
Answer:
8.7°
Step-by-step explanation:
The above problem can be represented by a right angled triangle with height of 7 m, hypotenuse = AB.
The base of the triangle is gotten by finding the diagonal of the road. That is using Pythagoras theorem:
base² = 43² + 15²
base² = 2074
base = 45.54 m
Using trigonometric function to find angle A:
tan(A) = base / height
tan(A) = 45.54 / 7
tan(A) = 6.506
A = tan⁻¹ (6.506)
A = 81.3°
Angle of depression = 90° - A = 90 - 81.3
Angle of depression = = 8.7°
The angels in a triangle should be 180° all
85+64+30=179<180
so we should add 1° to the first one
the angels would be 86 64 30
