Original price $45 mark down 22% ?

Mathematics
1 answer:
aleksklad [387]3 years ago
8 0

An item that costs $45, when discounted 22 percent, will cost $35.1. The easiest way of calculating discount is, in this case, to multiply the normal price $45 by 22 then divide it by one hundred. So, the discount is equal to $9.9. To calculate the sales price, simply deduct the discount of $9.9 from the original price $45 then get $35.1 as the sales price.

Write a polynomial function in standard form with given zero x=2,-1,-5
LekaFEV [45]

Answer:

Done below!

Step-by-step explanation:

(x - root)

(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)

(x^{2} +x-2x-2)(x+5)=(x^{2} -x-2)(x+5)=x^{3}+5x^{2}-x^{2}   -5x-2x-10\\\\=x^{3}+4x^{2} -7x-10

the pressure exerted on the floor by the heel of someone's shoe is inversely proportional to the square of the width of the heel
Katen [24]
P = k/w^2 

<span>first of all you need to find k </span>
<span>But I kind of don't like the units of each value so let say </span>
<span>400KPa = 4 * 10^5 Pa = 4 * 10^5 N/m^2 </span>
<span>2 cm = 2 * 10^-2 m </span>

<span>input values in the equation </span>

<span>4*10^5 = k/(4*10^-4) >>> k = 160 N </span>

<span>P = 160/w^2 </span>
<span>it said if she wears a heel with a width of .5 cm </span>

<span>P = 160(0.5 * 10^-2)^2 >>> P = 6400 KPa</span>
