Answer 1

Answer: The real answer is either A. Or from what I've been taught, Columbus thought that he could sail around the world to reach to India and did NOT know there were other lands. And he landed in America and he thought it was India.

Burger King calories 320Del Taco calories 280
Mcdonalds calories 280
Jack in the box calories 250
Wendy's calories 270

Find the mean number of calories for the hamburgers.
and the median number of calories for the hamburgers

Answers

arrange them from least to greatest form

250 cal., 270 cal., 280 cal., 280 cal., 320 cal.,

Mean = $(250+270+280+280+320)/(5)$
(5 because there is a total of 5 fast food restaurants' hanburgers)

= $(1400)/(5)$
Mean = 280 calories

Median = The number exactly in between,
In midst of these numbers, 280 is in the mid-way
Median = 280 calories

Answers

y = -1/2x +2 1/2
General equation;
y = mx + c

Calculating the slope;
Change in y/ (change in x) = gradient m

(2-1)/(1-3) = - 1/2

Replacing m gives;
y= -1/2x + c

Calculating the value of c
take point (1,2) above and replace y with 2 and x with 1
2=-1/2 *1 +c
c = 2 1/2
Equation then is
y = -1/2x +2 1/2

Answers

ANSWER

$log_(b)( {a}^(d) ) = d \: log_(b)(a)$

EXPLANATION

This is a straightforward property of logarithm.

It was derived from one of the laws of indices as follows,

Let
$a= {b}^(m) - - (1)$

We can write this as a logarithmic equation to get,

$m = log_(b)( a ) - - (2)$

When we raise both sides of equation (1) to the exponent of d, we get

${a}^(d) = ( {b}^(m) )^(d)$

${a}^(d) = ( {b}^(md) )$

We rewrite this last equation as logarithm

$log_(b)( {a}^(d) ) =md$

$m = log_(b)( a )$

This implies that
$log_(b)( {a}^(d) ) = d log_(b)( a )$
