So hmm check the picture below.
let's first convert each mixed to "improper fraction" and do the sum.
The properties that were used
to derive the properties of logarithms are the properties of exponent because
logarithms are exponents. The properties of exponents are: product of powers,
power to a power, quotient of powers, power f a product and power of a
quotient.
As an example, the log
property log(a^k) = k log (a) can be derived from the exponential property
(b^a)^k = b^(ak).
Likewise,
log (ab) = log (a) + log (b) comes from c^(a+b) = c^a*c^b
Proof:
Let x = c^a and y=c^b
Then,
log (x) = a and log (y) =
b (base c)
<span>log (xy) = log (c^a * c^b) =
log (c^(a+b)) = a+b = log(x) + log (y)</span>
If 3 sweaters = 390 $
Then 3 / 390 = 130$ per sweater
130$ * 22 = 2860$
Answer:
The gradient is m=1/3
Step-by-step explanation:
The gradient, known as the slope, is the rate of change, defined as the change in y divided by the change in x. In this case, we will select two points from the line and calculate the slope from there. I selected (0,3) and (3,4) to demonstrate:
Slope=m=(y2-y1)/(x2-x1)=(4-3)/(3-0)=1/3
Therefore, the gradient/slope is 1/3.
