How can exponential and logarithmic functions be combined?

1 answer:

4 0

It really depends on the question and what you want to solve. An exponential function can be written as y = x^2 and if you are solving for y then it will be log(base x) y = 2.

More Examples:
3x = 15
(log both sides with base of 3)
log(3)3x = log(3)15
since log(3)3 = 1 then,
(1)x = log(3)15
x = log 15 / log 3
= 2.465

Let m,n,p, and q represent nonzero positive integers. find a number in terms of m,n,p, and q that is halfway between m/n and p/q

alukav5142 [94]

This is the same as averaging. You add them and divide by 2.

((m/n) + (p/q))/2 would be a number in between m/n and p/q.

Do note that n and q must be nonzero, but luckily that is a given.

Y’all give me dis answer to

Answer:

The solution is: (1,-3)

Step-by-step explanation:

Given equations are:

x-y=4 Eqn 1

4x+y = 1 Eqn 2

Substitution involves finding value of a variable from one equation and putting in other equation

From equation 1

x = y + 4

Putting in equation 2

$4(y+4) + y = 1\\4y+16+y = 1\\5y = 1-16\\5y = -15\\\frac{5y}{5} = \frac{-15}{5}\\y = -3$

Putting y = -3 in equation 1

$x- (-3) = 4\\x + 3 = 4\\x = 4-3\\x = 1$

Hence,

The solution is: (1,-3)

(7x^3y^2)(4x^3y^2)<br><br><br>^=exponents<br>solve in scientific Notation

Hitman42 [59]

<h3>Answer:</h3>

(2.8×10¹)x⁶y⁴

<h3>Step-by-step explanation:</h3>

Multiplication can be done in the usual way, then the number converted to scientific notation. Scientific notation does not apply to the variables.

$(7x^3y^2)(4x^3y^2)=(7\cdot 4)x^{3+3}y^{2+2}=28x^6y^4\\\\=2.8\cdot 10^1x^6y^4$

_____

If you write the numbers in scientific notation to start, then do the multiplication, the effect is virtually the same: an adjustment is needed in the product to get it back to scientific notation.

(7)(4) = (7×10⁰)(4×10⁰) = 7·4×10⁰⁺⁰ = 28×10⁰ = 2.8×10¹
