Answer:

Step 1

Formulate a recursive sequence modeling the number of grams after n  minutes.

we have that

100%-17.1%-------------- > 82.9%------------> 0.829

a(n) = 780*[0.829^n]

for n=19 minutes

a(19)=780*[0.829^(19)]=22.1121 g---------------> 22.1 g

the answer is 22.1 g

Step-by-step explanation:

m-n = 3 becomes m=3+n

Substitute 3+n to m in m+n = 5

Therefore;

3+n+n = 5

3 + 2n = 5

2n = 2

n = 1

m - n = 3, n is 1

therefore;

m - 1 = 3

m = 4

The cash price of her purchase would be $5262.79

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]

The Present value = C [1 - (1+i)^(-n)]/i

C = the amount of payment per period

i = interest rate

n=number of payments

In this problem we have;

C = $174.80

i = 12% per year compounded monthly

 = 12/(12 x 100)

 = 0.01

n = 3 x 12 = 36 months

Present Value = 174.80[1  - (1+0.01)^(-36)]/0.01

Cash price = $5262.79

Hence, the cash price of her purchase would be $5262.79

x = -5, y = 8

Explanation:

we're gonna start by subtracting

3x + 2y = 1  x+y=3

Rewrite the equation:

x + y = 3 , 3 x + 2 = 1

Step: Solve x + y = 3 for x:

x + y = 3

x + y + −y = 3 + −y (Add -y to both sides)

x = −y + 3

Step: Substitute −y + 3 for x in 3x + 2y = 1:

3x + 2y = 1

3 (−y + 3) + 2y = 1

−y + 9 = 1 (Simplify both sides of the equation)

−y + 9 + −9 = 1 + −9 (Add -9 to both sides)

−y = −8

−y/−1 = −8/−1 (Divide both sides by -1)

y=8

Step: Substitute 8 for y in x=−y+3:

x = −y + 3

x = −8 + 3

x = −5 (Simplify both sides of the equation)

Answer:

x = √17

Step-by-step explanation:

x² = 4² + 1²

x² = 17

x = √17

x² = y² + z²

x² = 4² + 1²

x² = 16 + 1

x² = 17

x = √17✅

The function that describes the car's distance from Austin is

y = -60x + 500.

A function is a relationship between a number of inputs and outputs. A function is an association of inputs where each input is coupled with exactly one output. There is a range, codomain, and domain for every function.

Let x be the time period in hour.

And y is the distance from Austin.

We substitute the value of x =5 to the functions and see if it gives the output 200.

In A:

y = 60x -500

y = 60(5) - 500

y = -200

Distance is not negative. So, this is not a required function.

In B:

y = -60x +500

y = 200 miles.

This is a required function.

In C:

y = -40x + 500

y = -200 + 500

y = 300 miles.

This is not a required function.

In D:

y = 60x + 200

y = 300 + 200

y = 500 miles.

This is not a required function.

Therefore, y = -60x +500 is a required function.
