Answer:
y=4x + 7
Step-by-step explanation:
Line=y=ax+b
b = where the line crosses the y-axis (where x=0). Here, it's 7.
a= vertical distance ÷ horizontal distance.
You can take any pair of distances to a point on the line, for example (4,1) is easy to read in the graph.
x=0 to 1 (horizontal distance=1-0=1)
and
y= 0 to 4 (vertical distance= 4-0=4)
a=4÷1=4.
So, the answer is y=4x + 7 as a= 4 and b=7.
I would put 9 and 1/2 because there boots they have about 1 size differnce
Answer:
A. 54₁₀
B. 81₁₀
Step-by-step explanation:
To convert from base 4 to base 10, we simply do the following:
A. 312₄ to base 10
312₄ = (3×4²) + (1×4¹) + (2×4⁰)
312₄ = (3×16) + (1×4) + (2×1)
312₄ = 48 + 4 + 2
312₄ = 54₁₀
Therefore, 312₄ is equivalent to 54₁₀.
B. 1101₄ to base 10
1101₄ = (1×4³) + (1×4²) + (0×4¹) + (1×4⁰)
1101₄ = (1×64) + (1×16) + (0×4) + (1×1)
1101₄ = 64 + 16 + 0 + 1
1101₄ = 81₁₀
Therefore, 1101₄ is equivalent to 81₁₀.
Answer: p = X/(1-X)X + Y/(1-Y)Y

Answer:
Step-by-step explanation:
<em>Refer to picture.</em>
Let the distance to men are x and y and the distance between them is d.
The angle of depreciation is 27° and 30°, hence top angle of the triangle is 63° or 60°.
<u>Find the distance from the tower to men:</u>
- x = 20 tan 63° = 39.25 m
- y = 20 tan 60° = 34.64 m
<u>The distance between men is:</u>
- d =
