It will take the inattentive driver 5.22 seconds to come to a complete stop, assuming the car's deceleration remains constant.

An inattentive driver traveling 16.0 m/s when he notices a red light ahead and his car is capable of decelerating at a rate of [tex]3.06 m/s^2[/tex]. To determine how much time it will take for the car to come to a complete stop, we can use the following equation of motion:

v = v0 + at

where v is the final velocity (in this case, 0 m/s), v0 is the initial velocity (16.0 m/s), a is the acceleration (negative, because the car is slowing down), and t is the time.

Rearranging and solving for t, we get:

t = -v0 / a

t = -16.0 / (-3.06)

t = 5.22 seconds

So, it will take the inattentive driver 5.22 seconds to come to a complete stop, assuming the car's deceleration remains constant. This time can be used to determine the minimum distance the driver needs to maintain between himself and the vehicle in front of him to avoid a collision.

Answer:

Step-by-step explanation:

You want the slope-intercept form equation for the tangent line at point (π/6, 1) on the curve y = 2·sin(x).

The slope of the line at the point of tangency is the derivative of the curve at that point:

  y' = 2cos(x) = 2·cos(π/6) = 2(√3/2)

  m = √3 . . . . . approximately 1.7321

Solving the line's equation for b, we have ...

  y = mx +b

  b = y -mx = 1 -(√3)(π/6)

  b = 1 -π√3/6 . . . . . approximately 0.0931

The equation of the line is ...

  y = mx +b

  y = (√3)x +1 -(π√3)/6

Answer: The actual area of the living room floor is 11 feet * 18.9 feet = 208.9 square feet. The estimated area of the living room floor is 12 feet * 20 feet = 240 square feet.

The difference in cost between the flooring to cover the actual area and the flooring to cover the estimated area of the living room floor is 240 square feet - 208.9 square feet = 31.1 square feet.

Therefore, the approximate difference in cost is 31.1 square feet * $8 per square foot = $248.80, which is closest to option (D) $250.

Check the picture below.

The length and width of the rectangle are 11 and 78 respectively.

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

Given, the length of a rectangle is 4 inches more than its width.

let x be the width of a rectangle.

thus, length = 4 + width

From the general formula of area and perimeter:

Area of rectangle = length*width

Perimeter of rectangle = 2(length + width)

In our case,

Area = x * (4 + x)

Area = x² + 4x

Perimeter = 2( 4 +x+ x)

Perimeter = 8 + 4x

Since the area of the rectangle is equal 5 inches more than 2 times the perimeter.

Thus,

x² + 4x = 5 + 2(8 + 4x)

x² + 4x = 5 + 16 + 8x

x² + 4x = 21 + 8x

x² + 4x -8x -21 = 0

x² - 4x -21 = 0

x = 7 and -3

Thus,

the width of the rectangle = 7

and the length of the rectangle = 11

Maddie wrote six different equations based on the triangle below.Four of the six equations that Maddie wrote are correct which are options A, D , E and F.

This is referred to as a polygon with three edges and three vertices.

Triangle ABC was given in the picture.

∠A = 60° and ∠B = 90° which is given in the figure

sin 60° = perpendiculer /hypotenuse

√3/2 = BC/10

BC = √3/2 × 10

BC = 5√3

tan 60° = perpendiculer /base

√3 =  5√3/AB

AB = 5√3/√3

AB = 5

sin 60° = 5√3/10 = √3/2

cos 60° = base / hypotenuse

cos 60° = 5/10 = 1/2

tan 60° = perpendicular /base

tan 60° = 5√3/5 = √3

cot 60° = 1 /√3

Therefore the equations which are correct are sin 60° =√3/2, cos 60° = 1/2, tan 60° = √3, and cot 60° = 1 /√3.

Answer: To project the population in 2020, we can use the linear trend line equation.

First, we need to find the equation of the line. Let's use the two given points, (2000, 220,000) and (2010, 252,000), to find the slope of the line:

slope = (252,000 - 220,000) / (2010 - 2000) = 32,000

Next, we can use the slope-intercept form of the line equation: y = mx + b, where m is the slope and b is the y-intercept.

Plug in the first point: 220,000 = 32,000 * 2000 + b

Solve for b: b = 220,000 - 32,000 * 2000 = -44,000,000

The equation of the line is: y = 32,000x - 44,000,000

Finally, we can use the equation of the line to project the population in 2020:

y = 32,000 * 2020 - 44,000,000 = 264,000

So, the projected population in 2020 is 264,000.

Answer:

2,810 feet

Step-by-step explanation:

Take a look at the diagram

There are two triangles formed with a common side AB

AB represents the vertical height of the plane = 5150 feet

AC represents the distance of car 1 from O

In ΔABC, m∠A = 90°, m∠ABC = 38°

Since the three angles of triangle must add up to 180°
90 + 38 +m∠C = 180

128 + m∠C = 180°

m∠C = 180 - 128 = 52°

In a right angle triangle where one side is the angle ∅, the ratio of the side opposite this angle to the side adjacent to the angle is tan∅

Using the values provided we get
tan(52°) = 5150/AC

AC= 5150/tan(52) = 4,023.62 feet ≈ 4024 feet

This is the horizontal distance of the first  car from the plane

Similarly for ΔABD

m∠D = 180 - (90 + 53) = 37°
tan(37) = 5150/AD

AD= 5150/tan(53) = 6,834.28 feet ≈ 6834 feet

This is the horizontal distance of the second car from the plane

The distance between the two cars = 6,834 - 4,024

= 2,810 feet
