The balance of an investment account is $308.32

Nady [450]

The balance was $4400.25 before 4 years.

<h3>What is an Equation?</h3>

An equation is a mathematical statement formed when two expressions are equated using an equal sign.

The equations are useful in the determination of unknown parameters.

The equations are of various types, such as Trigonometric equations, and quadratic equations.

The balance of an investment account is $308.32

Let the balance 4 years ago was $x

Then the balance today is represented by x + 308.32

The current balance is $4708.57

The expressions can be equated to get the value of the balance 4 years ago.

x + 308.32 = 4708.57

x = 4708.57 - 308.32

x = $4400.25

The balance 4 years ago was $4400.25

Sinea thinks that the fully factored form of the expression (x^4-1) is (x^2-1)(x^2+1). Is she correct? Explain.

iVinArrow [24]

Answer:

No. See below.

Step-by-step explanation:

$( {x}^{4} - 1)$

Use the following formula (Difference of Two Squares)

${x}^{2} - {y}^{2} = (x + y)(x - y)$

$( {x}^{4} - 1) = ( {x}^{2} + 1)( {x}^{2} - 1)$

We are not done yet. As we can still factor the expression which is x²-1 by using the same formula.

$( {x}^{2} + 1)(x + 1)(x - 1)$

This is the fully factored form.

Find the volume , including units of a square pyramid with base length 5 cm and height 6cm

VARVARA [1.3K]

Answer:

50 cm^2

Step-by-step explanation:

The volume of a square pyramid can be found using:

v= 1/3 bh

Where b is the area of the base, and h is the height

First, we have to find the area of the base

a=l*w

In a square, all sides are equal, so we know the length and the width are both 5

a=5*5

a=25

Now, we can substitute 25 in for b, and 6 in for h

v=1/3bh

v=1/3(25*6)

v=1/3(150)

v=50

Volume uses units cubed, and in this case our units are centimeters

The volume is 50 cm^3

The equation that could be used to determine the total number of people is given as y is equal to 3^x.

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent y = a^x

where a is a constant and a>1

Let y be the total number of people that will be tagged.

And let x be a number of the round.

We are assuming the first is when Kyla posted a photo challenge on social media and tagged 3 friends.

So from the problem the equation becomes:

$\rm y = 3^x$

At first round x = 1, y =3

At second round x = 2, y = 9

At third round x = 3, y = 27

Thus, the equation that could be used to determine the total number of people is given as y is equal to 3^x.
