Answer:
35 cm
Step-by-step explanation:
You can use the Cosine Rule to find the length of a side when two sides and the included angle are given.
a² = b² + c² - 2bc cos A
a² = (36²) + (52²) - 2(36)(52) cos 42°
a² = (1296) + (2704) - (3744)(0.7431448255)
a² = (4000) - (2782)
a² = 1218
a = ✓1218
a = 34.9 cm
Answer:
-39
Step-by-step explanation:
||u|| = sqrt(5² + (-12)²)
= sqrt(25 + 144)
= sqrt(169)
= 13
||cu|| = c ||u||
c = -3
c ||u|| = -3 × 13 = -39

Total cost of 1 hour of parking is $2.
Explanation:
Given graph represents parking fees at a mall parking lot.
x-axis represents the hour of parking.
y-axis represents the cost of parking.
In the coordinate (1, 2),
1 represents hour of parking and 2 represents cost of parking
Hence, the coordinate (1, 2) represents the total cost of 1 hour of parking is $2.
The image of the graph is attached below.
