The dimensions for the block can be 3 x 4 x 5.

Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder.

For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.

Given:

We have wire of length 60 m.

Now, to find the length, width and height of block we have to factorize 60.

60 = 3 x 4 x 5

So, the measurement of the block can be length x width x height can be

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.

The common ratio is approximately -0.6.

Let the first term in the geometric series be "a" and the common ratio be "r". Then, the formula for the sum to infinity of a geometric series is:

S = a / (1 - r)

And the formula for the sum of the first n terms of a geometric series is:

Sn = a * (1 - r^n) / (1 - r)

So, using the information given:

18 = a / (1 - r)

And:

130/9 = a * (1 - r^4) / (1 - r)

Solving for "r" using these two equations:

18 = a / (1 - r) ==> a = 18 * (1 - r)

130/9 = a * (1 - r^4) / (1 - r) ==> 130/9 = 18 * (1 - r) * (1 - r^4) / (1 - r) ==> 130/9 = 18 * (1 - r^4)

Dividing both sides by 18:

7/5 = (1 - r^4)

So:

r^4 = 1 - 7/5 = -2/5

Taking the fourth root of both sides:

r = (-2/5)^(1/4)

So, the common ratio is approximately -0.6.

The mean is 14.7, the median is 16, and the mode is 16.

To find the mean, we need to calculate the sum of all the data values and divide it by the total number of observations.

The sum of the data values is:

14 x 14 + 15 x 11 + 16 x 23 + 17 x 10 + 18 x 13 = 196 + 165 + 368 + 170 + 234 = 1043

The number of observations is:

14 + 11 + 23 + 10 + 13 = 71

The mean is calculated as follows,

1043 / 71 = 14.7 (rounded to one decimal place)

The median is the central value in the data collection. To find the median, we need to arrange the data values in ascending order and find the middle value. In this case, we have an odd number of observations, so the median is simply the middle value.

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

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:

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

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

Answer:

x = 11

Step-by-step explanation:

both the petagons are similar so the sum of their sides will be same

i.e.

sum of ABCDE = sum of JKLMN

ABCDE = sum of all the five sides = 6+2+2+3+3 = 16
