solong [7]

Step-by-step explanation:

Initial velocity(u) = 60 km/hr = 50/3 m/s

final velocity(v)= 0 (stops at rest)

acceleration(a) = -0.05 m/s²

display (s)=?

v²-u²=2as

0²- (50/3)= 2(-0.05)s

2500/9= 0.1s

s= 25000/9 m

GaryK [48]

Answer:

Step-by-step explanation:

(7,6) (-3,-1)

(x1,y1) (x2,y2)

$Distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\=\sqrt{(-3-7)^{2}+(-1-6)^{2}}\\\\=\sqrt{(-10)^{2}+(-7)^{2}}\\\\=\sqrt{100+49}=\sqrt{149}\\\\=12.21$

For the given equation, find the values of a, b, and c, determine the direction in which the parabola opens, and determine the y

mariarad [96]

Answer:

Table A

Step-by-step explanation:

y = 3x^2 +2x -8

The quadratic is in the form

y = a x^2 +bx+c

a = 3 b = 2 c = -8

Since a > 0 it opens up

The y intercept is c so the y intercept is -8
