2010 7 607
2011 8 846
A quadratic regression model can be obtained using a quadratic regression calculator ; The quadratic regression modeled obtained is in the form :
y = Ax² + Bx + C
y = 26.3x² - 116.9x + 109.6

Answer:
80
Step-by-step explanation:
Since the three angles of a triangle add to give 180°
The the size of the largest angle 4 = 180° ×
= 180° ×
∴ the size of the largest angle = 80°
Answer:
18
Step-by-step explanation:
Evaluate (2 x^2)/y + 16 x^0 where x = 2 and y = 4:
16 x^0 + (2 x^2)/y = 16×2^0 + (2×2^2)/4
2/4 = 2/(2×2) = 1/2:
16×2^0 + 2^2/2
Combine powers. 2^2/2 = 2^(2 - 1):
16×2^0 + 2^(2 - 1)
2 - 1 = 1:
16×2^0 + 2
2^0 = 1:
16×1 + 2
16 + 2 = 18:
Answer: 18
Answer:
no
Step-by-step explanation:
plug them in
-4=3(-2)+2 find if its true
-4=-6+2
-4=-4
do the next one
-4=-3(-2)-4
-4=6-4
-4≠2
