The range of each amazon box is 1.6035m

According to the question we have been given that

        height of the conveyer belt = 1.4m

        Speed of the belt = 3m/s

We need to find the range of the amazon box, that is we have to find the distance.

Formula for distance is ,  d = speed * time

We have been given the value of speed we need to find the value of time. For that we will use the formula,

                                     h = [tex]\frac{1}{2} g t^{2}[/tex]

where,         h = height

                   g = acceleration due to gravity = 9.8m/s²

                    t = time

Putting the required value for t we get,

        t = [tex]\sqrt{\frac{2h}{g} } \\[/tex]

          = [tex]\sqrt{\frac{2(1.4)}{9.8} } \\[/tex]

          = √0.286

          = 0.5435 s

Putting the value of time in distance formula we get,

                d = 3 * 0.5435 m

The magnitude of vector →RS is 3√2

And the direction of vector →RS is given by an angle 315°

Let R(1,0) = (x1, y1) and

S(-2,3) = (x2, y2)

By distance formula, the magnitude of vector is

[tex]|\vec {RS}| = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\|\vec {RS}| =\sqrt{(-2-1)^2+(3-0)^2} \\\\|\vec {RS}| =\sqrt{(-3)^2+3^2} \\\\|\vec {RS}| =\sqrt{9+9}\\\\ |\vec {RS}| =3\sqrt{2}[/tex]

To find the direction of the vector RS :

[tex]tan(\theta)=\frac{y_2-y_1}{x_2-x_1} \\\\tan(\theta)=\frac{3-0}{-2-1}\\\\tan(\theta)=\frac{3}{-3}\\\\ tan(\theta)=-1\\\\ \theta=tan^{-1}(-1)\\\\\theta=45^{\circ}[/tex]

However, the angle is in the fourth quadrant, so we add  360°  to obtain a positive angle.

Thus,  −45° + 360° = 315° .

Therefore, the magnitude of vector →RS is 3√2

The correct option is F. 25.

The total number of gallons of gas Amanda will use to travel all the distances is 25.

The amount of between two things, or the state of being far apart, is defined as distance. A five-foot distance between two tables is an example of distance. The difference of the two sides of an issue is an example of distance.

Now, as per the given question;

Amanda plans to drive 160 miles, 235 miles, 185 miles, and 220 miles.

Thus, the total distance ravelled by Amanada is;

= 160 miles + 235 miles + 185 miles + 220 miles

= 800 miles

Amanada's car has the average of 32 miles per gallon of gas.

Thus, the car will cover a total of 32 miles for each gallon of gas.

Thus,

The number of gallon of gas requires = Total distance/(distance travelled for one gallon of gas)

The number of gallon of gas requires = 800/32

The number of gallon of gas requires = 25

Therefore, the gas required to travel a total distance of 800 miles is 25 gallons.

Answer:

.67 (See explanation for why)

Step-by-step explanation:

2/3

in order to turn this into a whole number, we are going to multiply the bottom number until it becomes any number starting with 1 and ending with a zero. this isnt possible Because 3 is a number that cannot do that.

So instead, we will multiply the number by 333

2*333 = 666

3*333 = 999

666/999 = 2/3

999 is nearly 1000, so lets write the decimal point 3 spaces inwards

.666

which can become

.66

The longer decimal for this(when using a calculator)

would give you

So the smaller number is 7, and the larger number is 27.

The best friend is the faster runner as his speed is 51.28 m/s while my speed is 48.78 m/s.

Speed is defined as the distance travelled by someone or something in unit time. The SI unit of speed is meters per second. The speed is calculated by dividing the distance travelled by the total time taken to travel said distance.  

Given the distance travelled by both of the friends is 400 meters.

Now The first friend travels this distance in 8.2 seconds:

Therefore speed is calculated by distance ÷ time

or, speed = 400 ÷ 8.2

or , speed = 48.7804... m/s

or, speed ≈ 48.78 meters per second

And the best friend travels this distance in 7.8 seconds:

Therefore speed is calculated by distance ÷ time

or, speed = 400 ÷ 7.8

or , speed =51.2820... m/s

or, speed ≈ 51.28 meters per second

Therefore by comparing both the speeds we can conclude that the best friend is the faster runner.

The base and height of triangle are 25 and 22 feet.

We are given the relation between base and height of triangle. Let us represent height with h and base with b. The equation relating the two quantities is as follows -

h = b - 3

Now, the area of triangle is given  by the formula -

Area = 1/2 × base × height

Keep the values in formula to find the base of triangle

275 = 1/2 × b × (b-3)

550 = b × (b-3)

b² - 3b - 550 = 0

b² + 22b - 25b - 550 = 0

b (b + 22) -25 (b + 22) = 0

(b + 22) (b - 25) = 0

b = -22 and 25

As the value of base can not be negative, so, the base of triangle is 25 feet.

Calculating height of triangle-

Height = Base - 3

Height = 25 - 3

Height = 22 feet

Hence, the base and height of triangle are 25 and 22 feet.

Answer:

the answer is great Britain because

Step-by-step explanation:

it is very good for this subject

The following set of numbers, 8, 15, and 17, can be the measures of the sides of a triangle, specifically a right triangle.

To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.

let a = 8, b = 15, and c = 17

a + b > c     8 + 15 > 17     23 > 17     True

a + c > b     8 + 17 > 15      25 > 15     True

b + c > a     15 + 17 > 8     32 > 8     True

To know what type of triangle based on the length of its side:

1. Take the sum of the squares of the two smaller sides.

8^2 + 15^2 = 289

2. Compare it to the square of the largest side.

17^2 = 289

289 = 289

If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.

if they are equal, it is a right triangle

if they are smaller, then it is an obtuse triangle.

Hence, 8, 15, and 17 can be the measure of the sides of a right triangle.

The common difference d is 6 and the first term a1 is 20.

The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same value.

The formula of Arithmetic progression is

a(n) = a1 + (n - 1)d

given that the two terms of arithmetic sequence,

a3 = 32 and a7 = -8.

now, find the common difference d.

a(n) = a1 + (n - 1)d

Let take a(n) = a7 and a1 = a3.

a7 = a3 + (7 - 3)d

a7 = a3 + 4d

now substitute the values of a6 and a4

-8 = 32 + 4d

-8 + 32 = 4d

d = 24/4

d = 6

so, the common difference d is 6.

then, find the term a1.

take the formula

a(n) = a1 + (n - 1)d

now, substitute a(n) = a3 and d = 6.

32 = a1 + (3-1)d

32 = a1 + 2d

32 = a1 + 2(6)

32 = a1 + 12

a1 = -12+32

11. The correct option is: The slope of f(x) is greater than the slope of g(x).

12. h(-5) = 10.

13. The equation is f(x) = 2x + 5.

14. The graph of y = f(x) will shift right 9 units.

The absolute value function is defined by the following piecewise rule, depending on the input of the function:

It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0, and has vertex(turning point) at (0,0). The range is from the y-coordinate of the vertex to positive infinity.

In item 9, from the table, the turning point is at (2,0), hence:

Vertex (2, 0), Range: {y | 0 ≤ y < ∞}

A linear function is modeled by the following rule:

y = mx + b

In which:

For item 10, we have that:

Then:

The equation is f(x) = -5x + 100.

For item 11, the slope is given by change in y divided by change in x, hence:

Hence:

The correct option is: The slope of f(x) is greater than the slope of g(x).

For item 12, we have that:

h(x) = -4x - 10.

Hence, when x = -5:

h(-5) = -4(-5) - 10 = 20 - 10 = 10.

Hence:

h(-5) = 10.

For item 13, we have that when x changes by 4, y changes by 8, hence the slope is:

m = 8/4 = 2.

When x = 1, y = 7, hence, considering the slope, when x = 0, y = 5, and:

The equation is f(x) = 2x + 5.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.

For this problem, the rule is given by:

y = f(x - 9).

The translation is x -> x - 9, hence:

The arithmetic series 1+5+9+. . . . . +41+45 can be expressed in summation notation as [tex]\sum\limits^{12}_{n=1} {(4n-3)}[/tex]

The given arithmetic series:

    1+5+9+. . . . . +41+45

To write the series in summation notation:

Find the common difference (d) of the series.

d = 5 - 1 = 4

Recall the formula for the nth term in an arithmetic sequence:

a(n) = a(1) + (n-1) . d

Substitute a(1) = 1 and d = 4:

a(n) = 1 + (n-1) . 4

a(n) = 4n - 3

Find n that leads to a(n) = 45

a(n) = 4n - 3

45 = 4n - 3

4n = 48

n = 12

Thus, the lower limit of the summation is n =1, and the upper limit is n = 12

Now write in summation notation as:

[tex]\sum\limits^{12}_{n=1} {a(n)}= \sum\limits^{12}_{n=1} {(4n-3)}[/tex]

This summation notation can be further simplified using the properties of summation operator:

[tex]\sum\limits^{12}_{n=1} {(4n-3)}=\sum\limits^{12}_{n=1} {4n}-\sum\limits^{12}_{n=1} {3}[/tex]
