Here hope this help the solution is X= -2 and y=9
Answer:
1/3
Step-by-step explanation:
60-90 is 30 numbers, right? So it is 30/90, or 1/3
c = 2(3.14)(radius)
c = 2(3.14)(3)
<em>multiply all those numbers together to get your circumference.</em>
c = 18.84.
Yo sup??
by Pythagoras theorem we can say that
DE²=3²+2²
=9+4
DE=√13
=3.60 units
angle D=tan-1(2/3)
=33.7
angle E=tan-1(3/2)
=56.3
Hope this helps

Answer:
D. y = -0.32x² -1.26x +15.81
Step-by-step explanation:
This is one of those multiple-choice questions where you only need a vague idea of what the answer is supposed to look like.
In this case the answer must be a quadratic equation with a negative leading coefficient. (The parabola opens downward.)
The only answer choice that is a 2nd degree polynomial with a negative leading coefficient is choice D.
__
A: linear equation
B: exponential equation
C: quadratic that opens upward (positive leading coefficient)
D: quadratic that opens downward -- the answer you're looking for
