kotegsom [21]

Answer:

$X=12.125\%$

Step-by-step explanation:

From the question we are told that:

Cost Price $CP=734$

Sale Price $SP=823$

Generally the equation for Profit P is mathematically given by

$Profit=SP-CP$

$P=823-734$

$P=89$

Therefore as a percentage

Percentage Profit X is given as

$X=\frac{89}{734}*100$

$X=12.125\%$

Answer:

From top to bottom;

1,1,3,3

Step-by-step explanation:

mathematically, for an even function;

f(x) = f(-x)

what this mean is that;

f(-1) = f(1)

f(-3) = f(3)

f(-5) = f(5)

f(-6) = f(6)

so we have it that;

f(-1) = 1

f(-3) = 1

f(-5) = 3

f(-7) = 3
