A bicycle has tires with a diameter of 26 inches. Find the radius and circumference of a tire. Round to the nearest hundredth, if necessary.

The sequence of the angles from least to biggest is ∠WXY < ∠YXZ < ∠WYX < ∠XZY < ∠XYZ.

A triangular is a geometry with 3 sides and three angles. The triangle has angles that sum up to 180 °.

In a triangle, the opposing side will be short if the angle is small, while the other side will be longer if the angle is larger.

The sides of the triangle are in ascending order, then we have

WY < YZ < WX < XY < XZ

Then the sequence of the angles is given as,

∠WXY < ∠YXZ < ∠WYX < ∠XZY < ∠XYZ

The sequence of the angles from least to biggest is ∠WXY < ∠YXZ < ∠WYX < ∠XZY < ∠XYZ.

Step-by-step explanation:

you don't know the Pythagoras formula yet ?

this is something you need to remember for life. this you will encounter everywhere (not just in school) :

c² = a² + b²

in a right-angled triangle c is the Hypotenuse (the side opposite of the 90° angle). a and b are the legs of the triangle.

4.

the legs of this right-angled triangle are the pole and the ground distance to the cable fixture on the ground.

the cable itself is the Hypotenuse (as the right angle is the angle between the pole and the ground distance).

so,

cable² = 8² + 6² = 64 + 36 = 100

cable = sqrt(100) = 10 m

5.

here we have a right-angled triangle with the direct distance between the points being the Hypotenuse, and the x and y coordinate differences are the legs.

so, we have

distance² = (3 - -3)² + (0 - -1)² = 6² + 1² = 36 + 1 = 37

distance = sqrt(37)

please note that since we are squaring, the direction of the differences and their signs do not matter. the square will turn positive and negative distances into positive numbers.

The simplification of the expression 3(x + 3y) - 5(x -y) is  -2x + 14y.

According to the given question.

We have an expression

3(x + 3y) -5(x -y)

As we know that, the simplification of an expression means to write an equivalent expression which contains no similar terms.

Therefore, the simplificantion of the expression  3(x + 3y) - 5(x -y) is given by

3(x + 3y) - 5(x -y)

= 3x + 9y - 5x + 5y     (by distributive rule)

= 3x - 5x + 9y + 5y

= -2x + 14y                    (adding and subtracting the like terms)

Hence, the simplification of the expression 3(x + 3y) - 5(x -y) is  -2x + 14y.

The distance the slower and faster car travelled are 360 km and 432 km respectively.

Two cars start at the same time from two towns 792 kilometres apart and meet in 9 hours.

One car can travel 8 km faster than the other car.

let

x = speed of the slower car

x + 8 = speed of the faster car

The cars meet in 9 hours and both cover a distance of 792 km.

Therefore,

speed = distance / time

distance = time × speed

Hence,

9x + 9(x + 8) = 792

9x + 9x + 72 = 792

18x = 792 - 72

18x = 720

divide both sides by 18

x = 720 / 18

x = 40

Therefore,

speed of the slower car = 40 km per hour

speed of the faster car = 48 km per hour

Hence,

how far the slower car go(distance) = 40 × 9 = 360 km

how far the faster car go(distance) = 48 × 9 = 432 km

The points on each axis where the function crosses will be the intercepts. Therefore, the p-intercept will be at the point where r = 0, and the r-intercepts will be at the point where C = 0.

We have been given the function as

C(r) = (r-6)(r+6)(r-5)

We have to determine the C-intercept and r- intercepts.

We should plug in 0 for r and solve.

Solving for the C-intercept

Plug in 0 for r.

C(0) = (0-6)(0+6)(0-5)

C(0) = 180

The C-intercept is (0, 180)

Solving for the r-intercepts, we get

Set the function equal to 0.

0 = (r-6)(r+6)(r-5)

Solve for the zeros.

(r-6) = 0 ⇒ r = 6

Explanation:

Refer to the diagram below.

Let's define these two point labels

A = (-9, -10)

B = (-5, -2)

which are the two given endpoints of the segment. Let's add in point C such that

C = (-5, -10)

Notice triangle ABC is a right triangle. The 90 degree angle is at point C.

--------------------

The x coordinates of points A and C are -9 and -5 respectively. This is a gap of 4 units. Split this into 8 pieces to find each is 4/8 = 0.5 units wide. Why 8? Because the "ratio 5 to 3" has a total of 5+3 = 8 parts.

Since the first number of that ratio is 5, we'll move 5 parts to the right of point A. So we'll move 5*0.5 = 2.5 units to the right of A.

We go from A(-9,-10) to D(-6.5, -10)

Take note how the segments AD and DC are in ratio 5:3

--------------------

The y coordinates of B and C are -2 and -10 in that order. This is a gap of 8 units. Split this into 8 equal parts, and each part is 1 unit tall.

Start at point C and move upward 5 of those parts, ie 5*1 = 5 units up. You should arrive at point E(-5, -5) shown in the diagram below.

Then draw a vertical line upward from point D until arriving at segment AB. At the same time, draw a horizontal line from point E until arriving at segment AB. Both approaches should get to point (-6.5, -5) which is the final answer. This is denoted as point F in the diagram below (marked in red).
