An arrowhead or point is the usually sharpened and hardened tip of an arrow, which contributes a majority of the projectile mass and is responsible for impacting and penetrating a target, as well as to fulfill some special purposes such as signaling.
<h3>Answer:</h3>
x = -2
<h3>Explanation:</h3>
The line represents the output value (y) for a given input value (x). Where the lines cross, the output values are equal. These lines cross at x=-2.
Answer:
you also have to translate 3 units to the right
Step-by-step explanation:
when you finished your reflections the coordinate of the point is (1, -1) while it should be (4, -4), that means you not only need to move it by 3 down but also to the right.
Answer:
12.5 inches
Step-by-step explanation:
Given the equation for the cross section of a parabolic satellite TV dish:
y=1/50x^2
Equation of a parabola :
(y - k) = 1/4p * (x - h)^2
Distance of the focus from the Vertex = p
Comparing both equations :
1/4p * (x - h)^2 = 1/50 * x^2
4p = 50
Divide both sides by 4
4p/4 = 50/4
p = 12.5 inches
Notice the lines and angles are in parallel.
(x + 10) and 40 are corresponding angles.
And corresponding angles are always equal
Therefore:
x + 10 = 40
x = 30 degrees
