Answer:
A.quadratic
Step-by-step explanation:
3x+x^2+4
Put in order from largest to smallest power of x
x^2 +3x+4
The highest power is 2
A.quadratic highest power 2
B. quartic highest power 4
C. linear highest power 1
D. cubic highest power 3
Let's eliminate x. To achieve this, mult. the 2nd equation by 2, obtaining
-8x + 2y = 10. Now add this result to the first equation:
8x-2y= -10
-8x + 2y = 10
---------------------
0
The two equations actually represent the same line. Without an x- or a y-value, we cannot solve for the value of the other variable. There are infinitely many solutions.
--------------------
Volume = pi r^2 (h/3)
100 = 3.14 (25) (h/3)
100 = 78.5 (h/3)
h= 3.82
or
h= 4
Thus,
Best answer is option a) 4.

Tangent = Opposite / Adjacent
sin(49) = 8/x
x = 8/sin(49)
x = 10.6
