Which function can be used to find t, the number of money Mellissa will have saved at the end of n weeks of doing chores?

Answer:

Decrease in amount= $578

Year-end amount= $7,922

Step-by-step explanation:

0.068=x/8500

Isolate x to multiply 0.068 by 8500= 578 which is the decrease in dollars.

so, 8500-578= $7,922 is how much money was in his account at the end of last year.

Decrease in amount: $578

Year-end amount: $7922

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Last year, Chang opened an investment account with, $8500.

At the end of the year, the amount in the account had decreased by 6.8%

To find the decrease in amount;

6.8% of $8500

= 8500 x 6.8 / 100

= 57800/100

= $578

At the end of the last year, amount,

$8500 - $578

= $7922

Therefore, the required amounts are $578 and $7922.

Answer:

40.5in

Step-by-step explanation:

Given data

Let the  width be x

L= 3x-15

Perimeter= 178cm

We know that

P=2L+2W

substitute

178= 2(3x-15)+2x

open bracket

178=6x-30+2x

collect like terms

178=8x-30

178-30= 8x

148= 8x

divide both sides by 8

x= 148/8

x=18.5 in

but L= 3x-15

L= 3*18.5-15

L=55.5-15

L=40.5 in

Hence the length is 40.5in

Step-by-step explanation:

The area of the polygon ABCD is 3/2 square units.

"It is two dimensional geometric figure having finite sides and vertices." A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.

here, we have,

we know that,

formula to find the area of the polygon:

"If polygon having vertices (x1, y1), ....(xn,yn) then the area of the polygon is,

A = 1/2 * | (x1y2 - x2y1) + ( x2y3 - x3y2) + .....+ (xny1 - ynx1)

This formula is also known as shoelace formula."

For given example,

the polygon  has vertices T(−3,1), S(−5,−4), A(−8,1), and N(−4,5)

Consider given vertices of polygon as,

(x1, y1) = (−3,1)

(x2, y2)=(−5,−4)

(x3, y3)=(−8,1)

(x4, y4)=(−4,5)

Using the formula of area of the polygon the area of the polygon ABCD would be,

A = 1/2 * | (x1y2 - x2y1) + ( x2y3 - x3y2) + .....+ (x4y1 - y4x1)

so, solving we get,

A = 1/2 | 17 + 27 - 36 -11|

A = 3/2

Therefore, the area of the polygon ABCD is 3/2 square units.

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Decrease rate (d)= 7%

Number of periods (n)= 7 years

Current population (PV)= 48,000

First, to calculate the future value, we need to use the following decrease exponential formula:

FV= PV*[(1+d)^-n]

After 7 years:

FV= 48,000*(1.07^-7)

FV= 29,892

The fish population after 7 years is 38783

An exponential decay is in the form:

y = abˣ;

where y, x are variables, a is the initial value of y and b is < 1

Let y represent the fish population after x years.

Since there is initially 48000 fish, hence a = 48000. Also it decrease at a rate of 3% per year. Hence b = 100% - 3% = 97% = 0.97

Therefore:

y = 48000(0.97)ˣ

After 7 years:

y = 48000(0.97)⁷ = 38783

Therefore the fish population after 7 years is 38783
