Answer:
equilateral triangle
Step-by-step explanation:
EQUILATERAL ... all three sides are equal length
ISOSCELES ... two sides are equal length
SCALENE ... none of the three sides are equal length
RIGHT ... one of the angles measures 90 degrees
OBTUSE ... one of the angles measures greater than 90 degrees
ACUTE ... all three angles measure less than 90 degrees
1) We can determine by the table of values whether a function is a quadratic one by considering this example:
x | y 1st difference 2nd difference
0 0 3 -0 = 3 7-3 = 4
1 3 10 -3 = 7 11 -7 = 4
2 10 21 -10 =11 15 -11 = 4
3 21 36-21 = 15 19-5 = 4
4 36 55-36= 19
5 55
2) Let's subtract the values of y this way:
3 -0 = 3
10 -3 = 7
21 -10 = 11
36 -21 = 15
55 -36 = 19
Now let's subtract the differences we've just found:
7 -3 = 4
11-7 = 4
15-11 = 4
19-15 = 4
So, if the "second difference" is constant (same result) then it means we have a quadratic function just by analyzing the table.
3) Hence, we can determine if this is a quadratic relation calculating the second difference of the y-values if the second difference yields the same value. The graph must be a parabola and the highest coefficient must be 2
Answer:
15
Step-by-step explanation:
because 35 divided by 5 is 7 and 15 divided by 15 is 3 making 7:3
