Answer: Hey I looked on a graphing calculator on Desmos, and its seems that this is increasing.
Step-by-step explanation:
30%*470=141 (So the number of students in 8 grade is 141)
9x² + bx + 64
\/(9x²) = 3x
\/84 = 8
2*3x*8 = 48x
b = 48
Answer:
Perpendicular(p)=21
base(b)=20
hypotenuse(h)=29
Step-by-step explanation:
Now by using the formula:
cos A=b/h
i.e 20 by 29
