1 answer:
Darina [25.2K]4 years ago
4 0

Answer:

y = 400(1.01)^t

Step-by-step explanation:

Firstly find the rate

(Take any balance for two years, e. g 400 and 404,412.12 and 416.24,etc to get simple interest)

408.04-404= 4.04

I=(P*R*T)/100

From which R=(100*I)/PT

R= 100*4.04/404*1

R=1%

Using compound interest formula

A =P(1+r/100)^n

where n is time

substituting each value

y = 400(1+1/100)^t

y= 400(1.01)^t

SOMEONE HELP! PLEASE! read the attached files
Trava [24]

Answer: 43 squared units

Explanation:

So the area is the total amount of the inside of the polygon (I’m not good at explaining) and you get your area from using measurements on the sides of the shape for example for a square let’s say the side is 4 and another side is 4 so you multiply that and you get 16 which is the area

So basically since this one is a open polygon you can just count the inside of the poly using the squares

Find the slope of the line that passes through the given points.<br> (-5,6) and (2,6)
CaHeK987 [17]

Answer:

0

Step-by-step explanation:

Your slope would be 0. To find the slope of a line given two points, you find the change in y over the change in x.

In this case, the change in y was 6 - 6 which equals 0.

The change in x was -5 - 2 which was -7.

Since your numerator is 0, 0 divided by anything is automatically equal to 0 no matter what the denominator is.

Therefore, your answer would be 0.

I hope this helped :)

I need to find X but I don't know how to do it
klio [65]
I think i am doing this right i am not sure. First you need to add up all the sides (100+38+22+15) it would equal 175 then you need to subtract it from 360 and get the missing value (x) then the answer would be 185

The total cost of Anfä's trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup:
daser333 [38]

Answer:

The cost of each cavity filling was $ 134.60.

Step-by-step explanation:

Given that the total cost of Anfa's trip to the dentist was $ 628.35, and she paid a flat fee of $ 89.95 which included the checkup: cleaning and then had 4 cavities filled, each of which cost the same amount, to determine which shows the correct equation and value of x, the cost of each cavity filling, the following calculation must be performed:

(628.35 - 89.95) / 4 = X

538.4 / 4 = X

134.6 = X

Therefore, the cost of each cavity filling was $ 134.60.

The exponential function g, whose graph is given below, can be written as g(x)=a*b^x
sveticcg [70]

Answer:

g(x) = 9(\frac{1}{3})^x

Step-by-step explanation:

Exponential function 'g' that can be written as g(x) = a.bˣ

From the graph attached,

Graph of the function passes through two points (0, 9) and (1, 3)

g(0) = a.b⁰

9 = a

Similarly, g(1) = a.b¹

3 = a.b

3 = 9(b)

b = \frac{3}{9}=\frac{1}{3}

Therefore function will be,

g(x) = 9(\frac{1}{3})^x
