If there isn't a base, the base is 10 :)

Answer:

10

Step-by-step explanation:

By convention we denote log of any number to base e as ln.

In mathematics and Calculus, whatever we do for log functions mean log to base e only.

But for practical uses, since we are using decimal system for numbers and numbers have place values in powers of 10, common logrithm is used.

Common logs have base 10 and used for calculation especially in Physics and Maths experiments

Hence a common logrithm written as log without any base means it implies that the base is 10

The slope intercept form of the equation of a line that passes through (-2,13) is y =5x-3what is the point slope form of the equ
Zigmanuir [339]

Answer:

y - 13 = 5(x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Given y = 5x - 3 in  slope- intercept form

with slope m = 5, then

m = 5 and (a, b) = (- 2, 13)

y - 13 = 5(x - (- 2)), that is

y - 13 = 5(x + 2) ← in point- slope form

An exponential function f(x) = ab^xpasses through the points (0, 2) and (3, 54). What are the values of a and
Vsevolod [243]

Answers:

a = 2

b = 3

=======================================================

Explanation:

Plug in x = 0 and y = 2 to find that

y = a*b^x

2 = a*b^0

2 = a*1

2 = a

a = 2

Then plug in x = 3 and y = 54 to determine the value of b

y = a*b^x

y = 2*b^x

54 = 2*b^3

2b^3 = 54

b^3 = 54/2

b^3 = 27

b = (27)^(1/3)

b = 3

So we have y = a*b^x update to y = 2*3^x

Which weighs more, a pound of feathers or a pound of bricks?
myrzilka [38]

Answer:

They both weigh the same amount.

Step-by-step explanation:

A pound of feathers would land and wouldn't hurt, but a pound of bricks would hurt.

Since they both are exactly one pound, if that is the only question and it's a one-part question then there's your answer.
