Answer:
50M
Step-by-step explanation:
The area of a trapezium = 1/2 x ( a + b) x h
a and b are the parallel sides
h = height
300sqm = 0.5 x (10 + b) x 10
divide both sides by 10
30 = 0.5 x (10 + b)
Divide both sides by 0.5
60 = (10 + b)
b = 60 - 10 = 50
The answer is c) 0 because if the line is horizontal it has no slope which makes it zero
Answer:
Therefore,
Step-by-step explanation:
Given:
Addition in Column form is as follow
m² + 2mn + n² + 0m + 5
+ 2m² + 0mn - 3n² + 0m - 2
+ 0m² - 3mn + 2n² + m - 3
<u> </u>
3m² - mn + 0n² + m+ 0
<u> </u>
Therefore,
The answer:
the vertex formula is V( -b/2a, f((-b/2a) )
so if The graph of y=ax^2+bx+c is a parabola that opens up and has a vertex at (0,5), then -b/2a = 0, implies b = 0, and when b =0 f((-b/2a = 0/2a=0))=f(0)
in our case, f(x)=<span>ax^2+bx+c, and it implies f(0) = c </span>≠ 5
so there is no value of a, b and c which verifies the equation of vertex, the set solution is {∅} (the empty set)
