The acceleration of the car three seconds before it comes to a stop is 0m/s²

Given the velocity function expressed as v(t) = -3t^2 + 18t + 9

Acceleration is the change in velocity of a body with respect to time.

a(t) = dv/dt

Differentiating the velocity with respect to time will give;

dv/dt = -6t + 18

a = -6t + 18

a = -3(6) + 18

a = -18 + 18

a = 0m/s²

Hence the acceleration of the car three seconds before it comes to a stop is 0m/s²

Answer:

  x = -3

Step-by-step explanation:

One always uses inverse operations to solve an equation.

  1/4x^3 = -27/4

  x^3 = -27 . . . . . . . . . multiply by the inverse of 1/4

  x = -3 . . . . . . . . . . raise each side to the inverse of the power of 3 (in English: take the cube root)

Check

  (1/4)(-3)^3 = 1/4(-27) = -27/4 . . . . as required

Mark me as brainlist

Step-by-step explanation:

P = Perimeter            

L = Length          

W = Width

Perimeter of rectangle = L + L + W + W        

or P = 2L + 2W

You know:

P = 36 inches

L = 2W          [length is(=) 2 times it's width]

W = ?

P = 2L + 2W    

Substitute/plug in what you know, plug in 2W for L since L = 2W

36 = 2(2W) + 2W         Simplify

36 = 4W + 2W

36 = 6W        Divide 6 on both sides

6 = W              Now that you know the width, you can find the length:

L = 2W

L = 2(6)

L = 12

L = 12 in

W = 6 in

PROOF

P = 2(12) + 2(6)

P = 24 + 12

P = 36

Answer:

  20 ≤ x ≤ 30

Step-by-step explanation:

The profit function is ...

  profit = revenue - cost

  = (-x^2 +80x) -(30x +600)

  = -x^2 +50x -600

  = -(x -20)(x -30)

The profit function will be positive where the signs of the factors are different: for x-values between 20 and 30. The profit function will be zero for x=20 and x=30.

The company will break even or make a profit for values of x that satisfy ...

  20 ≤ x ≤ 30

Answer:

7/21

Step-by-step explanation:

14/42

Divide the top and bottom by 7

14/7 =2

42/7 = 6

2/6 = 1/3

We need a ratio that is 1/3

7/21

Divide by 7

1/3

[a] See attached

  - Her chance of making it is 1/3, 1 - 1/3 = 2/3, so her chance of missing is 2/3

[b] 1/2 or one half

First chances (hit and hit): 1/4 * 1/3 = 1/12

Second changes (hit and miss): 1/4 * 2/3 = 2/12

Third chances (miss and hit): 3/4 * 1/3 = 3/12

(when multiplying fractions you multiply across)

Adding all chances together: 1/12 + 2/12 + 3/12 = 6/12 = 1/2

Step-by-step explanation:

first one: 2

second: 5

third: 8

fourth: 11

PATTERN NOTICED: +3 every sequence

therefore,

fifth: 14

sixth: 17

seventh: 20

eighth: 23

The number of tiles in the eighth figure will be 23.

The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmatic progression.

In the given sequence for the first figure, there are 2 tiles, for the second figure, there are 5 tiles, for the third figure, there are 8 tiles, and for the fourth figure, there are 11 tiles.

The pattern of the series can be seen below,

2, (2 + 3),( 2 + 3 +3), (2 + 3 + 3+3 ),( 2 +3+3+3+3),( 2+3+3+3+3+3) ,( 2+3+3+3+3+3+3) ,( 2+3+3+3+3+3+3+3) .........

2,5,8,11...........

The sequence will become,

2, 5,8,11,14,17,20,23........

Therefore, the number of tiles in the eighth figure will be 23.

Answer:

  15 cm

Step-by-step explanation:

All of the triangles in this figure are similar 30°-60°-90° triangles.

The ratio of shortest to longest sides in a 30°-60°-90° triangle is 1 : 2. This means the longest side of the largest triangle has length ...

  2 × (10 cm) = 20 cm

It also means the shortest side of the smallest triangle is (10 cm)/2 = 5 cm.

The length shown as 'x' is the difference of these measures:

  x = 20 cm -5 cm

  x = 15 cm

__

Additional comment

There are several "geometric mean" relations that apply to this sort of right-triangle geometry. One of them is that the side marked as 10 cm is the geometric mean of the short segment and the whole segment of the bottom edge. This will confirm that x = 15 cm.

  (10 cm)² = (5 cm)(5 +15) cm = 100 cm²
