Ava deposited $14 in a savings account that earns 2.7% simple interest. What would the graph look like?
katen-ka-za [31]

Deposited amount = $14.

Rate of interest =  2.7%

In decimals 2.7 could be written by dividing 2.7 by 100, we get

0.027.

Interest earned each year = 2.7% of $14 = 0.027*14 = $0.378.

We can make a table to balance by after each year.

First year balance: First year interest + Deposited amount = 0.378 +14 = $14.378.

Second year balance: Second year interest + Deposited amount = 2*0.378 +14 = 0.756+ 14 = $14.756.

Third year balance: Third year interest + Deposited amount = 3*0.378 +14 = 1.134+ 14 = $15.134.

We get four coordinates to graph A(0,14), B(1, 14.378) , C(2, 14.756) and D(3, 15.134).

Plotting those coordinates of the points A, B, C and D on the graph.

Find the value of x when 6 - 4x = 6x - 8x + 12
seraphim [82]

Answer:

x = -3

Step-by-step explanation:

Step 1: Write out equation

6 - 4x = 6x - 8x + 12

Step 2: Combine like terms (x)

6 - 4x = -2x + 12

Step 3: Add 4x on both sides

6 = 2x + 12

Step 4: Subtract 12 on both sides

-6 = 2x

Step 5: Divide both sides by 2

-3 = x

Step 6: Rewrite

x = -3

The side s of a square carpet is measured at 5 ft. Estimate using the Linear Approximation the maximum error in the area A of th
KonstantinChe [14]

Answer:

0.333 ft^2

Step-by-step explanation:

We are given that

Side of square carpet,s=5 ft

\Delta s=0.4 in=\frac{0.4}{12}ft

1 foot=12 in

We have to find the maximum error in the area of the carpet by using the linear approximation .

Area of square,A=(side)^2=s^2

dA=2sds

Substitute the values

dA=2\times 5\times \frac{0.4}{12}

dA=0.333ft^2

Hence, the maximum error in the area of the carpet=0.333 ft^2
