a car is stopped at a red light when the light turns green the car accelerates at 20 ft/sec/sec how long does it take for the car to go 1000 ft

Answers

Step-by-step explanation:

d = do + vo t + 1/2 at^2

when the car starts at zero velocity, this becomes

d = 1/2 a t^2

1000 = 1/2 (20) t^2

t^2 = 1000/ ( 1/2 * 20) shows t = 10 s

Find the maximum value of x+y given thatx>=-3
y>=5x-9
3x+y<=15

Answers

x ≥ -3
y ≥ 5x - 9
3x + y ≤ 15

3(-3) + (5x - 9) ≤ 15
    -9 + (5x - 9) ≤ 15
    (-9 - 9) + 5x ≤ 15
   -18 + 5x ≤ 15
   + 18    + 18
   5x ≤ 33
      5 5
   x ≤ 6.6
     y ≤ 5(6.6) - 9
   y ≤ 33 - 9
   y ≤ 24
   (x, y) ≤ (6.6, 24)

Y=2x-5
3x+8y+32=56
What does y and x equal?

Answers

y = 2x - 5
3x + 8y + 32 = 56
3x + 8(2x - 5) + 32 = 56
3x + 8(2x) - 8(5) + 32 = 56
3x + 16x - 40 + 32 = 56
19x - 8 = 56
      + 8   + 8
   19x = 64
      19    19
   x = 3.4
y = 2(3.4) - 5
y = 6.8 - 5
y = 1.8
(x, y) = (3.4, 1.8)

_________ is the quality a design has if it maintains all characterics when it is rotated about a point lying in its plane.A.Translation symmetry
B.Rotational symmetry
C.Two-fold symmetry

Answers

Rotational symmetry is the quality a design has if it maintains all characteristics when it is rotated about a point lying in its plane.

What is rotational symmetry?

Rotational symmetry is the property of a shape that looks the same after some rotation by a partial or full turn around a point.

The Rotational symmetry is the quality a design has if it maintains all characteristics when it is rotated about a point lying in its plane. A shape is said to possess rotational symmetry when it still looks the same after we rotate it.

Hence, the Rotational symmetry is the quality a design has if it maintains all characteristics when it is rotated about a point lying in its plane.
