3. Quincy deposits $400 in a new bank account that earns 4% simple interest per year. What

Illusion [34]

Answer:

$448

Step-by-step explanation:

We can use the simple interest formula for this:

$A = P (1 + rt)$

<em>P = initial balance</em>

<em>r = annual interest rate</em>

<em>t = time</em>

<em />

First, change 4% into its decimal form:

4% -> $\frac{4}{100}$ -> 0.04

Now, lets plug in the values:

$A=400(1+(0.04)(3))$

$A=448$

The total amount in the account after 3 years will be $448

Does anyone know the answer?

Answer:

We conclude that the area of the right triangle is:

$A\:=p^2-2p-3$

Hence, option A is correct.

Step-by-step explanation:

From the given right-angled triangle,

Base = p+1

Perpendicular = 2p-6

Using the formula to determine the area of the right-angled triangle

Area of the right triangle A = 1/2 × Base × Perpendicular

$=\frac{1}{2}\left(p+1\right)\left(2p-6\right)$

Factor 2p-6: 2(p-3)

$=\frac{\left(p+1\right)\times \:2\left(p-3\right)}{2}$

Divide the number: 2/2 = 1

$=\left(p+1\right)\left(p-3\right)$

$\mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$

$=pp+p\left(-3\right)+1\cdot \:p+1\cdot \left(-3\right)$

$=pp-3p+1\cdot \:p-1\cdot \:3$

$=p^2-2p-3$

Therefore, we conclude that the area of the right triangle is:

$A\:=p^2-2p-3$

Hence, option A is correct.

About how accurately must the tank's exterior diameter be measured to calculate the amount of paint it will take to paint the si

kondaur [170]

Answer: The error of the diameter would be 5% .

Step-by-step explanation:

Since we have given that

$S=2\pi rh$

Here, r is the radius

h is the height

So, it becomes,

$S=2\pi (\dfrac{D}{2})h\\\\S=\pi Dh\\\\S=\pi D\times 10\\\\S=10\pi D$

So, we will derivate S wrt D, we get that

$\dfrac{dS}{dD}=10\pi\\\\dS=10\pi dD$ ---------------------(1)

As we have given that

it will take to paint the side of the tank to within 5% of the true amount.

So, it becomes,

$dS=0.5\pi D$ ---------------(2)

So, from (1) and (2) , we get that

$0.5\pi D=10\pi dD\\\\\dfrac{0.5\pi}{10\pi}=\dfrac{dD}{D}\\\\0.05=\dfrac{dD}{D}=5\%$

Hence, the error of the diameter would be 5% .
