Answer:

[tex]P_1=11.7\\P_2=15.21\\P_n=9\cdot1.3^n\\P_{10}\approx124.07[/tex]

Step-by-step explanation:

An exponential function can be written in the form ...

y = a·b^x

where x is the independent variable, b is the common ratio, and 'a' is the initial value (when x=0). The "common ratio" is the ratio of each term to the one before. For example, b = P₁/P₀.

Here, you are told the initial value (P₀) is a=9, and the common ratio is b=1.3. The independent variable is given as n, so your population formula is ...

P(n) = 9·1.3^n

You are asked for values when n = 1, 2, and 10. Since you know the common ratio, you can simply multiply P₀ by 1.3 to get P₁:

P₁ = 1.3·P₀ = 1.3·9 = 11.7

Similarly, ...

P₂ = 1.3·P₁ = 1.3·11.7 = 15.21

You could continue up to P₁₀, but it is easier to use a calculator to evaluate the exponential function.

P(10) = 9·1.3¹⁰ ≈ 124.07

Maggie Jay owns her own car. Her June monthly interest was $250. The rate is 13 1/2 percent. Jay's principal balance at the beginning of June is: (Use 360 days)

Answers

Answer:

the principal balance at the beginning of June is $22,222.22

Step-by-step explanation:

The computation of the principal balance at the beginning of June is shown below:

Principal balance = Interest paid ÷ (Interest Rate ÷ 12 Months)

= $250 ÷ (13.5% ÷ 12)

= $22,222.22

Hence, the principal balance at the beginning of June is $22,222.22

Hello There!

So if you didn't know an exterior angle of a triangle is equal to the two opposite interior angles of a triangle

So basically

∠XYZ=∠WXY+∠XWY

so to find ∠XWY we subtract the value of ∠WXY (45) from the value of the exterior angle (115)

115-45=70 so ∠XWY=70

Answer:

?+45=115° sum of two interior angle of the triangle is equal to the exterior angle

<XWY=115-45=70

Question 4 ( i-Ready )
The system of equations 2y = 14 - 2x and y = -x + 7 is
graphed. What is the solution to the system of equations?
A. (0,-7)
B. No solution
C. (0,0)
B. Infinitely many solutions

Answers

Answer:

Step-by-step explanation:

Note that the two equations are equivalent.

2y = 14-2x can be rearranged to y = -x+7, which is the same as the second equation. What you're looking is one line on top of the other.

Every shared point is a solution. Since there are infinitely many points on a line, and these lines share every point, there are infinitely many solutions.

Help me as much as you can please :)

Answers

Answer:

Step-by-step explanation:

1). System of equations is,

-2x - y = -22 -------(1)

4x - 8y = 4 -------(2)

By satisfying these equations with the given point (9, 4),

Equation (1)

-2(9) - 4 = -22

-18 - 4 = -22

-22 = -22

True.

Equation (2)

4(9) - 8(4) = 4

36 - 32 = 4

4 = 4

True.

Given point lies on both the equations.

Therefore, the given point is the solution of the system of equations.

2). 3x - 3y = 27 -----(1)

-2x + 9y = -11 ------(2)

Satisfy the equations with the given point (-10, -1)

Equation (1)

3(-10) - 3(-1) = 27

-30 + 3 = 27

-27 = 27

False.

Equation (2)

-2x + 9y = -11

-2(-10) + 9(-1) = -11

20 - 9 = -11

11 = -11

False.

Therefore, the given point is not the solution of the system of equations given.

(Round your answer to two decimal places.) s =

Answers

Answer:

a) x = 1.52

b) s = 1.16

Step-by-step explanation:

We have that:

5 students watched 0 movies.

9 students watched 1 movie.

5 students watched 2 movies.

5 students watched 3 movies.

1 student watched 4 movies.

(a) Find the sample mean x.

Sum divided by the number of students. So

[tex]x = \frac{5*0 + 9*1 + 5*2 + 5*3 + 1*4}{5 + 9 + 5 + 5 + 1} = \frac{38}{25} = 1.52[/tex]

(b) Find the approximate sample standard deviation, s.

Standard deviation of the sample.

Square root of the sum of the squares of the values subtracted from the mean, divided by the sample size subtracted by 1. So

[tex]s = \sqrt{\frac{5*(0-1.52)^2 + 9*(1-1.52)^2 + 5*(2-1.52)^2 + 5*(3-1.52)^2 + 1*(4-1.52)^2}{24}} = \sqrt{\frac{32.24}{24}} = 1.16[/tex]

X + 4 < 6 help.......

Answers

Answer:

x<2

Step-by-step explanation:

Hello There!

Our objective for this problem is to isolate the variables

To do so we use inverse operations

x+4<6

subtract 4 from each side

4-4 cancels out

6-4=2

we're left with

x<2

Step-by-step explanation:

It is just like a normal x equation just with an inequality. So for now, just represent the < as and =

so we have x+4=6

subtract 4 from both sides

x+4-4=6-4

x=2

Now we insert the <

x<6

so all values for x are all less than 6

Hope that helps :)

Answers

Answer:

y = (x - 3.5)^2 - 18.25

Step-by-step explanation:

y = x^2 – 7x - 6

y = (x^2 – 7x) - 6

y = (x^2 – 7x + 3.5^2 - 3.5^2) - 6

y = (x^2 – (2)(3.5)x + 3.5^2) - 3.5^2 - 6

y = (x - 3.5)^2 - 3.5^2 - 6

y = (x - 3.5)^2 - 18.25
