Answer:
Any projectile that is under the rules of gravity can be modeled by a parabola!
Picture a football player kicking the ball up: it will follow a parabolic orbit, <u>and the vertex is the highest point it will reach.</u>
Picture a roller coaster: it will most likely follow a parabolic orbit, with the vertex being that scary moment on the top of the roller coaster track.:)
Answer is A because √9 is 3
The general form of the equation of a straight line is ax+by+c=0
slope = -a/b
so the slope in your equation = 3
to get the y-intercept put x = 0
y = -11
the equation is y = 3x -11
you can also get it by isolating the y , it will give you the same equation
Answer:
diagram of truss with some angles missing
What are the measures of the angles located at positions a, b, & c? Note: the figure is symmetrical on the vertical through angle b.
The large triangle is an isosceles triangle. The two angles on the base are equal. Angle a = 35°
We now know two angles in the largest triangle. The third angle, angle b must add to these to make 180°.
35° + 35° + b = 180°
b = 180° - 70°
b = 110°
We now know two angles in a quadrilateral. The two unknown angles, including angle c are equal. All four angles add up to 360°.
2c + 110° + 120° = 360°
2c = 360° - 230°
2c = 130°
c = 65°
