Distance and displacement are 45 km
Answer:
Step-by-step explanation:
The shape of this graph is that of a parabola. In this case the parabola opens down. The general form of the equation of such a parabola is
y = a(x - h)^2 + k, where (h, k) is the vertex and a is a coefficient to be determined.
In this particular case we can obtain the coordinates of the vertex (h, k) from the graph. They are (3, 4). Thus, h = 3 and k = 4. The graph goes through (1.5, 0). Use this information to determine the value of the coefficient a:
Then the equation of this parabola must be y = a(x - 3)^2 + 4.
0 = a(1.5 - 3)^2 + 4
Then:
0 = a(-1.5)^2 + 4, or
0 = 2.25a + 4, or
2.25a = -4, or
a = 16/9
Thus, the final result: The equation of this parabola is
y = (16/9)(x - 3)^2 + 4
whose graph is a parabola that opens down and has vertex (3, 4).
I am not 100 percent sure but i think you multiply and the answer is 7.75 if not then try to divid how you get 7.75 is you make 3/4 into a decimal and that becomes 0.75 them multiply by 10 and get 7.75
Answer:
X1 =-10, X2= 4
Step-by-step explanation:
|-3-x|-2=5
|-3-x|=5+2
|-3-x|= 7
-3-x=7
-4-x=-7
Then slove for X
