Answer:
10.53
Step-by-step explanation:
Given :
Height of building = 17m
John's eye level = 2 m
Total height (including eye level) = 17+2 = 19m
Angle of depression, θ = 61°
Let distance between John's friend and building = d
Using trigonometry :
Tan θ = opposite / Adjacent
Tan 61° = 19 / d
1.8040477 = 19 / d
d = 19 / 1.8040477
d = 10.53
4,500 mass. if you multiply 0.45 and 10,000 you'll get 4,500
Let the length of the first piece be x inches. Then:-
x + 2x + 4x + 3 = 38
7x = 38 - 3
x = 35/7 = 5 inches
Answer: the 3 pieces have lengths 5, 10 and 23 inches.
Answer:
2/x + 3/y = 5
Step-by-step explanation:
A linear equation refers to any equation that can be written in the form;
ax+b=0 or y - mx -c = 0
The graph of a linear equation will always be a straight line; Vertical, horizontal or with a given degree of steepness (slope).
All the equations given are linear, except the last equation;
2/x + 3/y = 5. The exponents of the variables x and y is not 1 hence the equation is non-linear. Find the graph attached;
