Find the principal which amounts to $918 in 1 year at a simple interest<br> of 2% per annum

Fantom [35]

Answer:

P = $900

Step-by-step explanation:

Simple Interest Formula: $A = P(1+rt)$

Where A is the final amount,

P = Principal

r = Interest Rate in Percent or $\frac{r}{100}$ per annum

t = time in years

From the information given in the question,

A = $918

r = 2% per annum or $\frac{2}{100}$

t = 1 year

Lets substitute these values to find P, the principal.

$P(1+(\frac{2}{100} )(1))=918\\P(1+0.02)=918\\1.02P=918\\P = \frac{918}{1.02} \\=$900$

Therefore, P = $900

A rock falls off a balcony. It’s height(in feet)is given by the formula f(x)= -16t^2+12.5t+150, where t is measured in seconds.

ELEN [110]

Answer: $3.47\ seconds$

Step-by-step explanation:

Given the following function:

$f(x)= -16t^2+12.5t+150$

You need to follow these steps in order to solve the exercise:

1. Substitute $f(x)=0$ :

$0= -16t^2+12.5t+150$

2. Now you need to apply the Quadratic formula. This is:

$x=t=\frac{-b\±\sqrt{b^2-4ac} }{2a}$

In this case, you can identify that:

$a=-16\\b=12.5\\c=150$

Then, you can substitute these values into the formula:

$t=\frac{-12.5\±\sqrt{(12.5)^2-4(-16)(150)}}{2(-16)}$

3. Evaluating, you get:

$t_1=3.47\\\\t_2=-2.69$

4. You must choose the positive value. Then:

$t=3.47\ seconds$

Which number round to 38,800 when rounded to the nearest hundred

V125BC [204]

There can be so many of such.

Eg. 38 750 38 835

38 795

38 820

Any of the numbers above when rounded to the nearest hundred would result in 38 800.

The idea is such that to make sure the 100 digit is 7 and the 10 digit is 5 or more.

Or if the 100 digit is already 8, then the 10 digit must be less than 5
