this store have increased at a rate of 3.75% per month. At this rate of growth, which function can

be used to determine the monthly cell phone sales x months after January?

f(x) = 417(1.375)*

f(x) = 417(3.75)

Final answer:

The bag contains 7 pennies, 11 quarters, 21 dimes, and 11 nickels. The value of the bag is $5.47.

Explanation:

Let's denote the number of pennies as P, nickels as N, dimes as D, and quarters as Q.

From the given information, we can form the following equations:

Substituting the values of P and D into the first equation, we can solve for Q:

7 (pennies) + (P + 4) (nickels) + 21 (dimes) + Q (quarters) = 50

11 + 7 + 21 + Q = 50

39 + Q = 50

Q = 50 - 39 = 11

Now, we can calculate the value of the coins:

Value of pennies: 7 * 0.01 = $0.07

Value of nickels: (7 + 4) * 0.05 = $0.55

Value of dimes: 21 * 0.10 = $2.10

Value of quarters: 11 * 0.25 = $2.75

The total value of the coins in the bag is $0.07 + $0.55 + $2.10 + $2.75 = $5.47.

Step-by-step explanation:

Given

5(2y + 1)² - 4 ← expand the factor using FOIL

= 5(4y² + 4y + 1) - 4 ← distribute parenthesis by 5

= 20y² + 20y + 5 - 4

= 20y² + 20y + 1

Answer:20y2+20y+1

Final answer:

To serve 48 people with the 'Almost No Fat Banana Bread' when the original recipe serves 12, multiply the quantities of each ingredient in the recipe by 4.

Explanation:

To adjust the recipe for 'Almost No Fat Banana Bread' to serve 48 people, where the original recipe makes 12 servings, you need to multiply the quantities of each ingredient in the recipe by 4. Since you are aiming to serve 1 piece each to 48 people and the original recipe serves 12, the calculation is:

Number of servings needed ÷ Original number of servings per recipe = Multiplier

48 servings needed ÷ 12 servings per recipe = 4

Therefore, you will multiply each ingredient by 4 to make enough banana bread for 48 servings.

Step-by-step explanation: store b

Answer:

Dimensions: 75.3778 ft and 66.3325 ft

Minimum price: $1658.31

Step-by-step explanation:

Let's call the length of the parking area 'x', and the width 'y'.

Then, we can write the following equations:

-> Area of the park:

x * y = 5000

-> Price of the fences:

P = 2*x*5.5 + y*5.5 + y*7

P = 11*x + 12.5*y

From the first equation, we have that y = 5000/x

Using this value in the equation for P, we have:

P = 11*x + 12.5*5000/x = 11*x + 62500/x

To find the minimum of this function, we need to take its derivative and then make it equal to zero:

dP/dx = 11 - 62500/x^2 = 0

x^2 = 65000/11

x = 250/sqrt(11) = 75.3778 ft

This is the x value that gives the minimum cost.

Now, finding y and P, we have:

x*y = 5000

y = 5000/75.3778 = 66.3325

P = 11*x + 62500/x = $1658.31

The dimensions that would minimize the total cost are [tex]66.3 \text{ by } 75.4[/tex]

The minimum cost is [tex]\$1658.3[/tex]

Let the sides of the rectangle be [tex]a[/tex] and [tex]b[/tex],

Let the total cost be given by [tex]T=7a+5.5(2b+a)[/tex]

The area, [tex]5000=a\times b \implies a=\frac{5000}{b}[/tex]

Substitute the formula for [tex]a[/tex] into the formula for [tex]T[/tex] to solve for [tex]b[/tex]

[tex]T=\frac{62500}{b}+11b[/tex]

To find the dimensions that would minimize the total cost,

[tex]\frac{dT}{db}=11-\frac{62500}{b^2}=0[/tex]

when

[tex]b=\pm \frac{250}{\sqrt{11}}[/tex]

[tex]\frac{d^2T}{db^2}=\frac{125000}{b^3}[/tex]

For minima, [tex]\frac{125000}{b^3}>0[/tex]

This means, [tex]b=+\frac{250}{\sqrt{11}}\approx 75.4 ft[/tex] is a minima

The corresponding value of [tex]a=\frac{5000}{b}=\frac{5000}{250}\times\sqrt{11}=20\sqrt{11}\approx 66.3 ft[/tex]

To find the minimum cost, substitute the above minimum value for [tex]b[/tex] into the formula for the total cost

[tex]T=500\sqrt{11}=\$1658.3[/tex]

Answer:

50th term is 159

Step-by-step explanation:

nth term=159

a + (n -1)*d = 159

12 + (n-1)*3= 159

(n - 1)*3 = 159 - 12

(n - 1)*3 = 147

n -1 = 147/3

n - 1 = 49

n = 49 + 1

n= 50

Answer: n=50th term

Step-by-step explanation:

An= a1+(n-1)d

An= nth term

A1= first term

N= nth position

D= common difference

An =159

A1= 12

D= 3

N= ?

Substitute the values

An=a1+(n-1)d

159=12+(n-1)3

Collect like terms

159-12=(n-1)3

147=3n-3

147+3=3n

150=3n

N=150/3

N= 50

Therefore 50th term will give 156
