Allison is playing a video game in which the number of jewels that can be collected doubles every level. On level 1, there are 3 jewels that can be collected. Which recursive formula gives the number of jewels Allison can collect on level n?

Step-by-step explanation:

Given

(x1 , y1) = ( 0 , 3)

(x2 , y2) = ( 1 , 8)

Now

Gradient =

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

[tex] = \frac{8 - 3}{1 - 0} \\ = \frac{5}{1} \\ = 5[/tex]

Hope it will help :)

Answer:

25

Step-by-step explanation:

[tex]5x^{2} - 2 ( y + 1)+9 = 5*2^{2} - 2(1 + 1) + 9 = 5 *4 - 4 +9 = 20 - 4 + 9 = 20 + 5 =25[/tex]

The four numbers whose sum equals 0, none of which are opposites are

-2,  4, -9, 7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Four numbers:

-2,  4, -9, 7

We see that,

The sum of the four numbers is 0.

-2 + 4 + (-9) + 7

= -11 + 11

= 0

None of the numbers are opposite.

Thus,

The four numbers are -2, 4, -9, and 7.

Answer:

if we carefully observe, left-bottom model contains 4 units on each side of the cube.

Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].

The correct model is attached below.

Step-by-step explanation:

Given the expression

[tex]\sqrt[3]{64}=4[/tex]

Cubing both sides

64 = 4³

Thus, the cube will have 4 units on each side.

Now, if we carefully observe, left-bottom model contains 4 units on each side of the cube.

Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].

The correct model is attached below.

Answer:

7.04× 10^5

Step-by-step explanation:

6.72 x 10^5= 6.72 x 10^(4+1)= 6.72 x 10^1 ×10^4

= 67.2 x 10^4

(67.2 x 10^4)+ (3.2 x 10^4)

(67.2+3.2) × 10^4 = 70.4 × 10^4

Answer:

20.25 lbs

Step-by-step explanation:

Multiply 27 by 3/4 or .75 to equal 20.25.

Answer:

36 pounds.

Step-by-step explanation:

Suppose Seher's dog weigh x pounds, here is an equation:

27=[tex]\frac{3}{4}[/tex]x

multiply 4 on both sides and dividing 3 on both sides, we get:

36=x

we flip this around:

x=36

So, Seher's dog weighs 36 pounds.

Answer:

[tex]J = 370g[/tex]

Step-by-step explanation:

Given

Represent the weight of the Jar with J and the sugar with S

Initially, we have:

[tex]J + S = 850g[/tex]

After 2/3 of sugar is removed we have:

[tex]J + S -\frac{2}{3}S= 530g[/tex]

Required

Determine the weight of the jar

[tex]J + S = 850g[/tex] --- (1)

[tex]J + S -\frac{2}{3}S= 530g[/tex] --- (2)

Simplify (2)

[tex]J + S -\frac{2S}{3}= 530g[/tex]

Take LCM

[tex]J + \frac{3S - 2S}{3}= 530g[/tex]

[tex]J + \frac{S}{3}= 530g[/tex]

Make S the subject in (1)

[tex]J + S = 850g[/tex]

[tex]S = 850g - J[/tex]

Substitute 850g - J for S in [tex]J + \frac{S}{3}= 530g[/tex]

[tex]J + \frac{850g - J}{3}= 530g[/tex]

Multiply through by 3

[tex]3 * J + 3*\frac{850g - J}{3}= 530g * 3[/tex]

[tex]3J + 850g - J= 1590g[/tex]

Collect Like Terms

[tex]3J - J= 1590g-850g[/tex]

[tex]2J= 740g[/tex]

Make J the subject

[tex]J = \frac{1}{2} * 740g[/tex]

[tex]J = 370g[/tex]

The jar weighs 370g

Answer:

one regular ticket costs $30

Step-by-step explanation:

The total number of people = 4

Without  the $20 coupon, the total cost would have been =100+20 = $120

Assume the price of one regular ticket is x;

4x = 120

Divide both sides by 4 to solve for x

x = 120/4

x = 30

Therefore, one regular ticket costs $30

Answer:

$30

Step-by-step explanation:

Since you pay 100 after discount, you add the 20 dollar discount to the 100 ($120)

Then since there are 4 of you in total, (you+ 3 friends), you divide by 4.

And Voila, your answer is $30 per person.
