find a formula for the nth term in this arithmetic sequence. a1=0, a2=0.5, a3=1, a4=1.5

Answers

Answer 1

Answer:

nth term is;

0.5n-0.5

Step-by-step explanation:

As we can see, the first term is 0

The common difference is 0.5-0= 1-0.5 = 1.5-1 = 0.5

Formula for nth term of an arithmetic sequence is;

a + (n-1)d

So we have

0 + (n-1) 0.5

= 0.5n-0.5

12x – 10y = -8
;
multiplication

Answers

Answer:

Step-by-step explanation: (Equation 2) = 12(-12+9y/4) - 10y = -8

-144+108y/4 - 10y = -8

-144 + 108y - 40y/4 = -8

-144 + 108y - 40y = -32

108y - 40y = -32+144

68y = 112

Y= 1.64

2-4x+9y=14

12x-10y= -8

2-14+9y = 4x

-12 + 9y = 4x ( equation 3)

(Put in equation 2)

Answer:

-4x + 9y = 14 answer is x = [tex]\frac{9}{4}y+ \frac{-7}{2}[/tex]

12x - 10y = -8 answer is x = [tex]\frac{5}{6}y +\frac{-2}{3}[/tex]

Step-by-step explanation:

solve for x

-4x + 9y = 14

add -9y to both sides

-4x + 9y + -9y = 14 + -9y

-4x = -9y + 14

divide both sides by -4

-4x/-4 = -9y + 14/-4

Anwser

x = [tex]\frac{9}{4}y + \frac{-7}{2}[/tex]

solve for x

12x - 10y = -8

add 10y to both sides

12x - 10y + 10y = -8 + 10y

12x = 10y -8

Divide both sides by 12

12x/12 = 10y - 8/12

Anwser

x = [tex]\frac{5}{6}y +\frac{-2}{3}[/tex]

one month jane rented 9 movies and 7 video games for a total of $56 the next month she rented 3 movies and 5 video games for a total of $34 find the rental cost for each movie and each video game

Answers

You are trying to find the values of two quantities, so you will need to set up a system of two equations in two variables. We'll call M the price of a move and V the price of a video game.

The first month: 9 movies, 7 video games, $56. Let's translate this into algebra:

9M + 7V = 56

The second month: 3 movies, 5 video games, $72. Translated:

3M + 5V = 34

Solve that system of equations.

how many sides does a polygon have if the measure of each exterior angle is 18? what is the sum of the measures of the interior angles?​

Answers

Answer:

20 sides3240°

Step-by-step explanation:

The sum of measures of exterior angles is 360°, so the number of sides (n) can be found from ...

  18° × n = 360°

  n = 360/18 = 20

The polygon has 20 sides.

The radius of a circular field is 35m. Calculate the area path 3.5m wide running inside the field.

Answers

Answer: Twenty one meeters!!

Answer:  The area of the path running around the inside edge of the field is  731.2 m²

If the path is across the middle of the field, the area of that path is about 245m²

Step-by-step explanation:

The radius of the field is 35m, subtracting 3.5 from that leaves the radius of the inside edge of the path at 31.5 m

The area of the path will be the difference between the two areas.

π × 35² = 3848.45

π × 31.5² = 3117.25

3848.45 - 3117.45 = 731.2

If the path is across the middle of the field, use the diameter, 70m,  times the width of the path, 3.5m,  to find the area of that path: 245m²

I hope this helps.

(see picture below)

thank you!

Answers

Answer:

x = 6

Step-by-step explanation:

If two secants are drawn from a point outside the circle, then the product of the lengths of one secant and its external segment equals the product of the lengths of the other secant and its external segment

Let us solve the question.

∵ There is a circle in the given figure

∵ There are two secants intersected at a point outside the circle

∵ The length of one of them = 8

∵ The length of its external segment = x

∵ The length of the other secant = 4 + 8 = 12

∵ The length of its external segment = 4

→ By using the rule above

8 × x = 12 × 4

∴ 8x = 48

→ Divide both sides by 8

x = 6

A

Step-by-step explanation:

B is wrong because it's saying to multiply the cost by $7.35.

C is wrong because it's telling you to add the amount of grams to $7.35.

A is the correct answer because you have to mutiply the cost by the grams which is what a number by a variable means.

are plotted on the vertical axis.

They are together plotted on the point

(x,y) = (x, f(x))

This is why we usually write the functions as:
