Answer 1

Answer:

Sue travels for 3 hours and a half

Sue stays stationary for 2 hours and a half

Step-by-step explanation:

Everytime the curve climbs, it means Sue is travelling. Everytime the curve stays flat, it means Sue is stays stationary. It remains to count up the total for both categories, with one square being 30 minutes.

Answer 2

Sue spends 3.5 hours on travelling and 2.5 hours stationary.

What is distance-time graph?

It is a graph which shows how far an object has travelled in a given time.

What is a stationary graph?

It is graph of function which represents there is no change in the function value or the function value is constant.

What is change in value?

"subtract old value from new value."

For given example,

Given distance-time graph represents a journey made by Sue.

Let 't' represents the travelling time and 's' represents the stationary time.

If we observe the graph,

from 2 pm to 3 pm Sue travelled 5 miles

⇒ t1 = 3 - 2

⇒ t1 = 1 hour

from 3.5 pm to 4 pm she travelled 10 miles

⇒ t2 = 4 - 3.5

⇒ t2 = 0.5 hour

from 5 pm to 6.5 pm she travelled 15 miles

⇒ t3 = 6.5 - 5

⇒ t3 = 1.5 hours

from 7.5 pm to 8 pm she travelled 5 miles

⇒ t4 = 8 - 7.5

⇒ t4 = 0.5 hour

So, the total travelling time would be,

⇒ t = t1 + t2 + t3 + t4

⇒ t = 1 + 0.5 + 1.5 + 0.5

t = 3.5 hours

Also, Sue spends stationary from 3 pm to 3.5 pm

⇒ s1 = 3.5 - 3

⇒ s1 = 0.5 hour

She spends stationary from 4 pm to 5  pm

⇒ s2 = 5 - 4

⇒ s2 = 1 hour

She spends stationary from 6.5 pm to 7.5 pm

⇒ s3 = 7.5 - 6.5

⇒ s3 = 1 hour

So, the total stationary time would be,

⇒ s = s1 + s2 + s3

⇒ s = 0.5 + 1 + 1

s = 2.5 hours

Therefore, Sue spends 3.5 hours on travelling and 2.5 hours stationary.

Answers

Answer:

The answer is below

Step-by-step explanation:

The question is not complete, a complete question is in the form:

Use a reference angle to find the exact value of the sine, cosine, and tangent of each angle. 260°

Solution:

There are four quadrants which divides into four equal parts. If θ is the angle:

If θ falls in the first quadrant, the reference angle = θ

If θ falls in the second quadrant, the reference angle = 180 - θ

If θ falls in the third quadrant, the reference angle = θ - 180

If θ falls in the fourth quadrant, the reference angle = 360 - θ

Given 260°, this falls in the third quadrant, hence the reference angle = 260 - 180 = 80°.

In the third quadrant, sine and cosine are negative while tangent is positive. Hence:

sin(260) = -sin(80) = -0.985

cos(260) = -cos(80) = -0.174

tan(260) = tan(80) = 5.67

Composite numbers are whole numbers that contain more than two elements.. Examples of composite numbers include 36 and 42. These numbers are divisible by more than just 1 and themselves. 36 is divisible by 1, 2, 3, 4, 6, 9, 12, and 18. 42 is divisible by 1, 2, 3, 6, 7, 14, and 21.

Example 1: To find the factors of 36

Step 1: Start by dividing 36 by 2, which gives us 18.

Step 2: Divide 18 by 2, which gives us 9.

Step 3: Divide 9 by 3, which gives us 3.

Step 4: Divide 3 by 3 which gives us 1.

Step 5: The factors of 36 are 1, 2, 3, 4, 6, 9, 12, and 18.

Example 2: To find the factors of 42

Step 1: Start by dividing 42 by 2, which gives us 21.

Step 2: Divide 21 by 3, which gives us 7.

Step 3: Divide 7 by 7 which gives us 1.

Step 4: The factors of 42 are 1, 2, 3, 6, 7, 14, and 21.

What is the solution of the pair of equations y 0 and y =- 3?

Answers

The solution of the pair of equations y = 0 and y = -3 is y = -3/2.

The given pair of equations is:

y = 0

y = -3

We can solve this pair of equations using elimination. To do this, we first add the two equations together, which gives us:

y + y = 0 + (-3)

2y = -3

We then divide both sides by 2 to get the solution for y:

2y/2 = -3/2

y = -3/2

A thing with both magnitude and direction is called a vector. A vector can be conceptualised geometrically as a directed line segment, the length of which corresponds to the magnitude of the vector, and the direction of which is denoted by an arrow. Size and direction are two independent characteristics of a quantity or phenomena known as a vector. The phrase also describes how these numbers are represented mathematically or geometrically.

Answer:

∠1 = 90° because the figure is a kite and the diagonals form 90° angles

∠2 = 90° - 27° = 63°

∠3 = ∠2 = 63°

Answer:

m<1 = 90 degrees

m<2 = 63 degrees

m<3 = 63 degrees

Step-by-step explanation: Angle 1 is a right angle, which is equal to 90 degrees. To find angle 2, you must know that a triangle's angles all add up to 180 degrees. You must realize that the angle below the 2 is 90 degrees since it is supplementary to angle 1. Now, you have to add the given angle of 27 degrees to 90 degrees and then subtract that sum from 180 degrees to get an answer of 63 degrees (27+90=117 --> 180-117=63). Angles 2 and 3 have the same value because they are basically symetrical to one another since both of their triangle's side lengths are equivalent.

Write an exponential function f so that the slope of a line from the point (0, f(0)) to the point (2, f(2)) is equal to 12.

Answers

The exponential function f so that the slope of a line from the point (0, f(0)) to the point (2, f(2)) is equal to 12 is defined as follows:

f(x) = 5^x.

How to define the exponential function?

The general format of an exponential function is given as follows:

y = ab^x.

In which:

a is the initial value.b is the rate of change.

The slope of a line, given two points, is given by the division of the change in the output by the change in the input of these two points.

Considering that the slope of points (0, f(0)) and (2, f(2)) is equals to 12, we have that:

[f(2) - f(0)]/(2 - 0) = 12

f(2) - f(0) = 24.

One case that satisfies this involves these two following points.

(0,1) -> f(0) = 1.(2,25) -> f(2) = 25.

Hence the parameter a is given as follows:

a = 1.

When x = 2, y = 25, meaning that the parameter b is calculated as follows:

b² = 25

b = 5.

Hence the exponential function is:

f(x) = 5^x.

Step-by-step explanation:

A. Area of the base of the pyramid = length x length

                                               = 3 x 3

                                               = 9 [tex]cm^{2}[/tex]

B. Area of one lateral face of the pyramid = area of a triangle

                                                = [tex]\frac{1}{2}[/tex] x base x height

                                                = [tex]\frac{1}{2}[/tex] x 3 x 6.4

                                                = 9.6 [tex]cm^{2}[/tex]

Area of one lateral face of the pyramid  = 9.6 [tex]cm^{2}[/tex]

C. The lateral surface area of the pyramid =  4 x area of one lateral face

                                                  = 4 x 9.6

                                                  = 38.4

The lateral surface area of the pyramid =  38.4 [tex]cm^{2}[/tex]

D. The total surface area of the pyramid = lateral surface area of the pyramid +  area of the base

                                                  = 38.4 + 9

                                                  = 47.4

The total surface area of the pyramid = 47.4 [tex]cm^{2}[/tex]

Answers

Answer:

y = -3x +20

Equation of line: y =mx + b

Where m is the slope and b is the y-intercept.

3x + y = 17

Write the above equation in y = mx +b form.

      y = -3x + 17

m = -3

Parallel lines have same slope.

So, slope of the required line is (-3).

     y = -3x + b

This line is passing through (4,8). Substitute in the above equation and find the value of 'b'.

Answers

A large rectangular box has a volume of 15. 75 cubic feet the box is 2. 5 feet long and 1. 5 feet wide. So the height of the box is 4.2 feet.

The formula to find the volume of a rectangular box is

V = lwh

where l is the length, w is the width, and h is the height.

Given that the volume of the box is 15.75 cubic feet, the length is 2.5 feet and the width is 1.5 feet, we can use the formula to find the height.

V = lwh

15.75 = 2.5 × 1.5 × h

h = 15.75/ (2.5 × 1.5)

h = 4.2

Therefore, the height of the box is h = 4.2 feet

Are 2 sides of an isosceles triangle?

Answers

Yes, the lengths of the two sides of an isosceles triangle are equal.

An isosceles triangle is a type of triangle that has two sides that are equal in length. The other side of the triangle can be either longer or shorter than the two equal sides. The two equal sides are called the legs, and the other side is called the base. The angles opposite the two equal sides are also equal in measure. Because of this, the two equal sides create an angle bisector that divides the base into two equal parts. This angle bisector forms two angles of equal measure as well. Thus, the two equal sides of an isosceles triangle are a defining feature of the shape.
