The correct answer would be C., I believe, because you take the opposite of the coordinate and subtract one. Hope this was helpful! (:

Answer:
v = 23
Step-by-step explanation:
Formatting the question gives;
a = mg - kv² / m
Make v subject of the formula as follows;
(i) Multiply both sides by m
ma = m²g - kv²
(ii) Collect like terms
kv² = m²g - ma
(iii) Divide through by k
v² = (m²g - ma) / k
(iv) Take the square root of both sides
v = √ [(m²g - ma) / k] --------------(ii)
From the question:
a = 2.8
m = 12
g = 9.8
k = 8/3
Substitute these values into equation (i) as follows;
v = √ [(12²(9.8) - 12(2.8)) / (8/3)]
v = √ [(1411.2 - 33.6) / (8/3)]
v = √ [1377.6 / (8/3)]
v = √ [1377.6 x (3/8)]
v = √ [1377.6 x 3 / 8)]
v = √ [516.6]
v = 22.73
v = 23 [to the nearest whole number]
Therefore v = 23 to the nearest whole number
Answer:
x=26
Step-by-step explanation:
The sum of all angles in a triangle is equal to 180
x + 55 + (4x-5) = 180
Combine like terms
5x +50 = 180
Subtract 50 from each side
5x +50-50 = 180-50
5x = 130
Divide each side by 5
5x/5 =130/5
x =26
