The first three terms of an arithmetic sequence are as follows.3, -1, -5

Answers

We will take a look at how we go about with arithmatic progressions.

Arithmmetic sequences are caetgorized by the following two parameters:

[tex]\begin{gathered} a\text{ = First term} \\ d\text{ = common difference} \end{gathered}[/tex]

Where,

[tex]\begin{gathered} \text{The value of the first term is called ( a )} \\ \text{The common difference between each and every successive value in a sequence is called ( d )} \end{gathered}[/tex]

We are given the following arithmetic sequence:

[tex]3\text{ , -1 , -5 , }\ldots[/tex]

Now we will try to determine the values of the two parameters ( a and d ) from the given sequence as follows:

[tex]\begin{gathered} a\text{ = 3 }(\text{ first term value )} \\ d\text{ = (-1 ) - ( 3 ) = (-5 ) - ( -1 ) = -4 ( common difference )} \end{gathered}[/tex]

Now to determine the value of any term number ( n ) in an arithmetic sequence we use the following formula:

[tex]a_n\text{ = a + ( n - 1 )}\cdot d[/tex]

Where,

[tex]n\text{ is the term number}[/tex]

So if we plug in the values of arithmetic sequence parameters into the general equation above we get:

[tex]\textcolor{#FF7968}{a_n}\text{\textcolor{#FF7968}{ = 3 + ( n - 1 ) }}\textcolor{#FF7968}{\cdot}\text{\textcolor{#FF7968}{ ( -4 )}}[/tex]

Now we are to determine the values of term numbers ( n = 4 ) and ( n = 5 ). We will evaluate the ( an ) for each term number as follows:

[tex]\begin{gathered} \text{\textcolor{#FF7968}{For n = 4}} \\ a_4\text{ = 3 + ( 4 - 1 )}\cdot(-4\text{ )} \\ a_4\text{ = 3 - 12} \\ \textcolor{#FF7968}{a_4}\text{\textcolor{#FF7968}{ = -9}} \\ \\ \text{\textcolor{#FF7968}{For n = 5}} \\ a_5\text{ = 3 + ( 5 - 1 )}\cdot(-4\text{ )} \\ a_5\text{ = 3 - 1}6 \\ \textcolor{#FF7968}{a_5}\text{\textcolor{#FF7968}{ = -}}\textcolor{#FF7968}{13} \end{gathered}[/tex]

Hence, the next two consecutive numbers in the arithmetic sequence would be:

[tex]3\text{ , -1 , -5 ,}\text{\textcolor{#FF7968}{ -9}}\text{ , }\text{\textcolor{#FF7968}{-13}}[/tex]

A bridge AB is to be built across a river. The point C is located 62m from B, and angle A is 80 degrees, angle C is 60 degrees. How long is the bridge

Answers

The points A, B, and C form a triangle.

From the given information in the question, the triangle ABC can be drawn to have the following parameters:

Recall the Sine Rule. Applied to the triangle above, the rule is stated as follows:

[tex]\frac{BC}{\sin A}=\frac{AC}{\sin B}=\frac{AB}{\sin C}[/tex]

The length of the bridge is AB. Given that the measures of angles A and C, and side BC are known, the following ratio is used to solve:

[tex]\frac{BC}{\sin A}=\frac{AB}{\sin C}[/tex]

Substituting known values, the length of AB is calculated as follows:

[tex]\begin{gathered} \frac{62}{\sin80}=\frac{AB}{\sin60} \\ AB=\frac{62\times\sin60}{\sin80} \\ AB=54.52 \end{gathered}[/tex]

The bridge is 54.52 m long.

2. Write the formula for the circumference of a circle.



a. Calculate the circumference of circle B if the diameter is 8 inches.


b. Calculate the radius of circle B if the circumference is 94.2 square centimeters.

Answers

Step-by-step explanation:

2. C = [tex] 2 \pi r [/tex]

a. to find radius from diameter in order to calculate the value of the circumference we have to divide the diameter by 2

d/2 = 8/2 = 4

Next, Find the circumference

C = [tex] 2 \pi r [/tex]

C = [tex] 2 \cdot 3.142 \cdot 4 [/tex]

C = 25.13

b. Rearrange formula for circumference to find the value of the radius

Where, C = [tex] 2 \pi r [/tex]

Make r the subject of formula

C/[tex] 2 \pi [/tex] = [tex] 2 \pi r [/tex] /[tex] 2 \pi [/tex]

94.2/2 × 3.142 = r

94.2/6.3 = r

r = 14.95 ≈ 15

2.circumference= pi×diameter

a)25.136 inches

b)14.99 cm

Step-by-step explanation:

a) pi × 8

3.142× 8= 25.136

b) diameter = radius × 2

circumference = pi × diameter OR pi × radius×2

because we are trying to find the radius we will use the pi × 2 radius.

94.2= 3.142 × 2 radius

94.2 ÷ 3.142= 2 radius

29.981 = 2 radius

29.981 ÷ 2 = radius

14.99 = radius

7. Find the slope of a line which passes through the origin and point (2,4).A 0.5B -0.5C 2D 4

Answers

Answer:

C

Step-by-step explanation:

the slope of a line is the ratio (y coordinate change / x coordinate change) when going from one point on the line to another.

in our case here we are going e.g. from the origin (0, 0) to (2, 4).

so, x changes by +2 (from 0 to 2).

y changes by +4 (from 0 to 4).

therefore, the slope is

+4/+2 = 2

FYI - the direction is not important. it works the same way in the other direction. but what is important : once you pick a direction for one coordinate, you have to use the same direction for the second one. you cannot go e.g. for x in one direction and for y in the other.
