The first time Lori played a game, she scored 100 points. She doubled her previous score each of the next 3 times she played the game. What was Lori's scored the first 4 times she played the game

Answers

Answer 1

Answer:

1500 points

Step-by-step explanation:

Given

[tex]Initial\ Score = 100[/tex]

[tex]Rate = 2[/tex]

Required

Determine the total score in first 4 games

This question illustrates a geometry progression and will be solved as follows:

[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]

Where

[tex]a = First\ Term = 100[/tex]

[tex]r = common\ ratio = 2[/tex]

[tex]n = 4[/tex]

[tex]S_4 = \frac{100(2^4 - 1)}{2 - 1}[/tex]

[tex]S_4 = \frac{100(16 - 1)}{1}[/tex]

[tex]S_4 = \frac{100(15)}{1}[/tex]

[tex]S_4 = 1500[/tex]

Hence, the score in first four games total 1500 points

Find the equation of OP.

Answers

The required equation of a circle P is x² + (y −3)² = 4. The correct answer is option (F).

As per the shown figure, the circle P with a center at (0, 3) and a radius is 2 units.

The center of the circle is given as (h,k) = (0, 3)

So the equation of the circle is:

⇒ r² = (x − h)² + (y − k)²

Substitute the values of r, h, and k in the above equation,

⇒ 2² = (x − 0)² + (y −3)²

⇒ 4 = x² + (y −3)²

⇒ x² + (y −3)² = 4

Hence, the equation of a circle P is x² + (y −3)² = 4.

x^7/y^7 (top right)

Step-by-step explanation:

Exponents are added together when multiplied, so it would equal x^7y^-7, but to get rid of the negative, the y would become the denominator in a fraction.

Answer:

x^7/y^3

Step-by-step explanation:

x^3+y^2+x^4+y^-5

re-arrange

x^4+x^3+y^-5+y^2

x^4+3+y^2-5

x^7+y^-3

let the minus(-)with the 3 be taken away

hence;

x^7/y^3

hence 3 is then possitive

The function w=30-3/4n represents the weight w in pounds of the papers in tyrones newspaper delivery bag after he delivers n newspapers. Find the zero and explain what it means in the context of this situation. Find the domain and range

Answers

Answer:

domain (−∞,∞)

range (−∞,∞)

n = 40 and it refers to the fact that after delivering 40 newspapers, there will be no paper left in the bag

Step-by-step explanation:

To find the zero, we equate the linear equation to zero

w = 30 - 3n/4

3n/4 = 30

3n = 120

n = 120/3

n = 40

What this mean in this context is that the the bag becomes empty after he has delivered 40 newspapers or we can say that the maximum number of papers the bag can take is 40

The range refers to the number on the y-axis

Here the range is (−∞,∞)

The domain refers to the x axis values

We have (−∞,∞)

Carlo and Helen spend the same amount of money on art supplies. Carlo buys 4 glue sticks and spends $3 on glitter. Helen buys 2 glue sticks, and she spends $3.75 on tape and $2.75 on paint. What is the cost, x, of each glue stick

Answers

Answer:

1.75

Step-by-step explanation:

The cost of each glue stick is $1.75 if Carlo and Helen spend the same amount of money on art supplies.  

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Carlo and Helen spend the same amount of money on art supplies.

Let the cost of each glue stick is x

Carlo spent:  4x + 3

Helen spent: 2x + 3.75 + 2.75

4x + 3 = 2x + 3.75 + 2.75

2x = 6.5 - 3

2x = 3.5

x = 3.5/2

x = $1.75

Thus, the cost of each glue stick is $1.75 if Carlo and Helen spend the same amount of money on art supplies.

Answers

Answer:

The coordinates of Q are (1.5,3)

Step-by-step explanation:

Here, we simply want to divide the line segment in the given ratio

We can use the internal division formula here;

The coordinates of Q will be;

(x,y) = (nx1 + mx2)/(n + m) , (ny1 + my2)/(n + m)

m = 5, n = 3

(x,y) = (3(-1) + 5(3))/(5 + 3) , (3(-2) + 5(6)/(5 + 3))

(x,y) = (-3 + 15)/8 , (-6 + 30)/8

(x,y) = 12/8, 24/8

Teri invested $2500 in an account with an interest rate of 2.75% compounded continuously. How
long will it take for Teri's account to earn $6000?

Answers

The time it will take for Teri's account to earn $6000 = 87 years

The total amount of money invested by Teri ( p) = $2500

The interest rate of the investment (r) = 2.75%

The simple interest is ( I) = $6000

Therefore the time to generate the interest of $6000

[tex] \frac{i \times 100}{p \times r \: } = t[/tex]

Therefore, time =

[tex] \frac{6000 \times 100}{2500 \times 2.75} [/tex]

[tex] \frac{600000}{6875} [/tex]

=87 years.

Therefore, the time it will take for Teri's account to earn $6000 = 87 years
