What's the length of side ab in δabc shown?

a. √15
b. 6
c. 5
d. √313

don't put wrong answer!

THE CORRECT CHOICE IS C

Now in this problem we aren't finding for the hypotenuse, we're actually finding for one side.

The hypotenuse is 13 and the other side is 12.

Using Pythagoras' theorem

side² = hyp²–side²

AB² = 13² – 12²

AB² = 169 – 144

AB² = 25

AB = √25

AB = 5

THEREFORE IT'S C

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
