Answer:

The explicit equation is [tex]\mathbf{a_n=5n+3}[/tex]

Option A is correct option.

Step-by-step explanation:

Third term of sequence is 18

Sixth term of sequence is 33

We need to find the explicit equation for the sequence.

The explicit sequence is [tex]a_n=a_1+(n-1)d[/tex]

We need to find a_1 the first term and common difference d

We have a₃=18

We can write it as: [tex]a_3=a_1+(3-1)d\\[/tex]

[tex]18=a_1+2d[/tex]

a₆=33

We can write it as: [tex]a_6=a_1+(6-1)d\\33=a_1+5d[/tex]

Now, solving these equation s we can find value of d

[tex]18=a_1+2d[/tex]

[tex]33=a_1+5d[/tex]

Subtract both equations

[tex]18=a_1+2d[/tex]

[tex]33=a_1+5d[/tex]

[tex]--------\\-15=-3d\\d=\frac{-15}{-3}\\d=5[/tex]

So, we get common difference d = 5

Now finding a_1

Put value of d in equation [tex]18=a_1+2d[/tex]

[tex]18=a_1+2(5)\\18=a_1+10\\a_1=18-10\\a_1=8[/tex]

So, we get a₁ = 12

Now, the explicit equation is:

[tex]a_n=a_1+(n-1)d\\a_n=8+(n-1)5\\a_n=8+5n-5\\a_n=5n+3[/tex]

So, the explicit equation is [tex]\mathbf{a_n=5n+3}[/tex]

Option A is correct option.

Answer:

9

Step-by-step explanation:

k  = 6

3k - 9  = 3*6 - 9

           = 18 - 9

            = 9

Answer:

They are the same slope

Step-by-step explanation:

When you convert both equations you get y=-[tex]\frac{1}{2\\}[/tex]x-[tex]\frac{5}{2}[/tex]

Applying the distance formula, the distance between the the Math building to the History building is: 5 units.

To find the distance between two given points on a coordinate grid, the distance formula which is used is: [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Given the following:

Plug in the values into the distance formula:

d = √[(4−1)² + (9 − 5)²]

d = √[(3)² + (4)²]

d = √(9 + 16)

d = √25

d = 5

Distance between the the Math building to the History building is: 5 units.

Answer:

It is D ................

Answer:

The  [tex]\mathbf{Slope=\frac{1}{4}}[/tex]

The y-intercept is (0,3)

Option D is correct.

Step-by-step explanation:

A linear function given has following points:

x      y

-8     1

0      3

We need to find slope and y-intercept

To find slope, we can use formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have x_1=-8, y_1=1, x_2=0, y_2=3

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{3-1}{0-(-8)}\\Slope=\frac{3-1}{0+8}\\Slope=\frac{2}{8}\\Slope=\frac{1}{4}[/tex]

So, we get [tex]\mathbf{Slope=\frac{1}{4}}[/tex]

We need to find y-intercept.

y-intercept can be found by putting x =0.

Looking at the table, when x =0, y=3

So, y-intercept is (0,3)

The required answer is:

The  [tex]\mathbf{Slope=\frac{1}{4}}[/tex]

The y-intercept is (0,3)

Option D is correct.

Answer:

Move all terms not containing d

to the right side of the inequality.

Inequality Form:

d<7

Step-by-step explanation:

Sorry no graph

Answer:

d < 7

Step-by-step explanation:

d + 12 < 19

1. Subtract 12 from both sides

d + 12 - 12 < 19 - 12

d < 7

Answer: 50 calories

Step-by-step explanation:

One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. The fraction that comes from fat:

= 90/150 = 3/5

One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. The fraction that comes from fat here:

= 12/120 = 1/10

The fat that are provided by a 100 calorie serving of the microwave popcorn would be:

= 3/5 × 100

= 60

The fat that are provided by a 100-calorie serving of the pretzels would be:

= 1/10 × 100 = 10

The difference from fat that are provided by a 100 calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels would be:

= 60 - 10

= 50 calories

Answer:

im in 9th and i still cant do this :(

Answer:

19 weeks

Step-by-step explanation:

Harley has an initial amount in his account = $500

He spends the amount each week = $20

He wants to have more than $100 in his account at the end of summer to purchase some new shoes.

We assume that he can withdraw the money from his account for 'w' weeks,

Inequality representing this situation will be,

(500 - 20w) > 100

Further solving this inequality,

-20w > 100 - 500

-20w > -400

w < 20

Therefore, Harley can withdraw the money for less than 20 weeks or 19 weeks.

Answer:

372.5 miles

Step-by-step explanation:

First, find how many miles she traveled at 65 mph:

65(2.5)

= 162.5

Then, find how many she traveled at 60 mph:

60(3.5)

= 210

Add these together:

162.5 + 210

= 372.5

So, Ella traveled 372.5 miles in total

Answer:

Translated 2 units Right

and Translated 4 units left and Across the y - axis

Now the new function is

h(x) = -( x + 2 )³ - 4

Step-by-step explanation:

Step(i):-

Type of transformation                                change of function

a)   The translated left 'c' units                           x - c

b)  The translated Right 'c' units                        x + c

Step(ii)

The given function  f(x) = x³

The given function is translated '2' units right side then the new function

  h(x) = ( x + 2 )³

and next  the translated '4 ' units left sides and reflected across the y-axis

Now the new function is

h(x) = -( x + 2 )³ - 4

Answer: left, down,x-axis

Answer:

v = [tex]\frac{4t-1}{3}[/tex]

Step-by-step explanation:

Given

t = [tex]\frac{3v+1}{4}[/tex] ( multiply both sides by 4 to clear the fraction )

4t = 3v + 1 ( subtract 1 from both sides )

4t - 1 = 3v ( divide both sides by 3 )

[tex]\frac{4t-1}{3}[/tex] = v

Answer: (d)

Step-by-step explanation:

Given

No of tickets sold can be given by the equation

[tex]35x-260>1000[/tex]

Solving inequality

adding 260 on both sides

[tex]35x-260+260>1000+260\\35x>1260[/tex]

Now, divide the inequality by 35

[tex]x>\frac{1260}{35}\\x>36[/tex]

Thus artist need to sell a minimum of 37 tickets to earn more than $1000

Answer: 18.0%

Step-by-step explanation:

Given: Cost of plane ticket =  £610  = $ 610 x 1.34      [ £1 = $1.34 ]

= $ 817.4

Airport tax = $180

Total cost = $(817.4+180)= $997.4

The percentage of the total cost does Edward spend on airport tax = [tex]\dfrac{180}{997.4}\times100\approx18.0\%[/tex]

Hence, the required answer = 18.0%
