Answer:

x=104

Step-by-step explanation:

Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)

10.5 = 1/2( x-83)

Multiply each side by 2

2* 10.5 = 2*1/2( x-83)

21 = x-83

Add 83 to each side

21+83 = x-83+83

104 =x

Hope this help!!!

Answer:

a4 = 123

Step-by-step explanation:

Here, we want to find the value of the 4th term

we simply have n as 4

substituting this, we have;

a4 = (a3)^2 + 2

But a^3 = (a2)^2 + 2 and

so we have ;

a4 = [(a2)^2 + 2]^2 + 2

But a2 = (a1)^2 + 2

a4 = {[(a1)^2 + 2)]^2 + 2}^2 + 2

Now, substitute the value of a1

a4 = (1)^2 + 2)^2 + 2)^2 + 2

a4 = (1 + 2)^2 + 2)^2 + 2

a4 = (3^2 + 2)^2 + 2

a4 = 11^2 + 2

a4 = 121 + 2

a4 = 123

Answer:

$2.20 per kilogram

Step-by-step explanation:

Take the total cost and divide by the number of kilograms

15.40/ 7

2.20

$2.20 per kilogram

Answer:

Step-by-step explanation:

I am not sure if this is corect but you need to devide 7 by 15.40

and that is my best estimate

Answer:

3

Step-by-step explanation:

fractions are division, so if you divide the numerator by the denominator you'll always get the mixed number / whole number

so 3/4 is equal to 3 divided by 4

15 divided by 5 is 3, because 3 x 5 = 15

Answer:

C, n < –3 or n > –2

Step-by-step explanation:

Answers:

b)  92100 decimeters

c)   6650 decaliters

=====================================================

Work Shown for part b)

1 decameter = 10 meters

1 decimeter = 1/10 of a meter

10 decimeters = 1 meter .... multiply both sides by 10

100 decimeters = 10 meters ... multiply both sides by 10

100 decimeter = 1 decameter

921*(100 decimeter) = 921*(1 decameter)

92100 decimeters = 921 decameters

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

Work Shown for part c)

We could follow the same idea as part b). I'm going to use another approach as shown in the diagram below. This conversion method is known as the railroad tracks method in some math textbooks.

Each column represents two things that are equivalent to one another. For example, 1 kiloliter is the same as 1000 liters. So each column, when you divide top over bottom, represents the value 1.

Notice the unit cancelations as shown by the color coding. The goal is to have every unit cancel except for the decaliters unit which is what we want to end up with ultimately.

Once you have the railroad tracks set up, you multiply straight across.

Along the top, we have 66.5*1000*1 = 66500

Along the bottom we have 1*10 = 10

Divide those results: 66500/10 = 6650

So 66.5 kiloliters converts to 6650 decaliters

Answer:

13 and -6      or     6 and -13

Step-by-step explanation:

Use systems of equations

The undefined term is point.

In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle. Let us read about the different parts of an angle.

Parts of an Angle

There are two main parts related to an angle - the arms and the vertex.

Arms of the Angle

The two rays which join at a common point to form the angle are called the arms of the angle. Observe the figure given below which shows that OA and OB are the arms of the angle AOB.

[tex]vertex[/tex]of the angle

[tex]vertex[/tex] is a common endpoint that is shared by the two rays. Observe the figure in which the [tex]vertex[/tex] O is marked as the joining point of the two arms.

Measure of an angle

An angle is measured in degrees. One full rotation around a point forms a complete angle of 360°.

As, the is defined on the basis of arms , vertices, measurement.

They all related to point and point doesn't have a particular definition.

Answer:

y-value is direct variation

Step-by-step explanation:

Solve the equation for inverse and cross multiply.

Answer:

x^2

Step-by-step explanation:

all the numbers are square roots so n square is the nth term.

2^2= 4

3^2=9

4^2=16

5^2=25

6^2=36

Answer:

[tex] {n}^{2} [/tex]

Step-by-step explanation:

Drawing number into triangular dot pattern and making a square (with same numbers of dots in rows and columns) will give a square number. Similarly, 16 = 42 = 32 + (3 + 3 + 1), 25 = 52 = 42 + (4 + 4 + 1) and so on.

Answer:

279 feet

Step-by-step explanation:

To find x, we solve using the Trigonometric function of Tangent

tan θ = Opposite/ Adjacent

θ = 64°

Length of the shadow = Adjacent = 136 feet

Height of the building = Opposite = h

Hence,

tan 64 = h/136 feet

Cross Multiply

h = tan 64 × 136 feet

h = 278.84132245 feet

Approximately, h to the nearest foot ≈ 279 feet

Therefore, the height of the building = 279 feet

Explanation:

Draw a vertical line through 5 on the x axis. This represents the equation x = 5. Notice that we intersect the blue line at (5,-1) which tells us that f(5) = -1. There's a closed point here, meaning that the point is included. This is in contrast to the open hole at (5,3) which is not part of the function. So be careful not to say that f(5) = 3 because that's not the case.

Answer:

i think it's f(5) - a wild guess

Step-by-step explanation:
