Answer:
The first question would likely be y=10.
The second question would likely be x=20.
Answer:
Option (3)
Step-by-step explanation:
By applying cosine rule in the triangle ABC,
BC² = AC² + AB² - 2(AC)(AB)cosA
5² = 3² + 7²- 2(3)(7)cosA
25 = 9 + 49 - 42cos(A)
25 = 58 - 42cos(A)
cos(A) = 
A = 
A = 38.21°
A ≈ 38°
Option (3) will be the correct option.
Answer:
y = -1/4x -2
Step-by-step explanation:
the perpendicular slope would be -1/4
2 = -1/4 (-16) + b
b = -2
the equation should be y = -1/4x -2
None of the answers you typed could be correct.
The answer is 90%. You get this answer by multiplying both the numerator and denominator by 5 so 18x5=90 and 20x5=100 giving you a fraction of 90/100 and a percentage of 90%.
Answer:
Domain) all x
Range) 1
Step-by-step explanation:
The domain is the x values and the range is the y values
In this case anything could be x, and y can only be 1
