Suppose a man’s scalp hair grows at a rate of 0.35 mm per day. What

iVinArrow [24]

<span>1cm = 10mm
1 inch = 2.54 cm
1ft = 12 inch
(0.35 mm / day) * (1 cm / 10 mm) * (1 in / 2.54 cm) * (1 ft / 12 in) =
0.001148... ft/day
</span>Now converting days into centuries:
1 year = 365 days
1 century = 100 year
(0.001148 ft / day) * (365 day / 1 yr) * (100 yr / 1 cent)
= <span>41.9 ft/century</span>

Write a quadratic function for each graph described.

user100 [1]

Answer:

$y=2x^2-\frac{4}{3}x-\frac{10}{3}$

Step-by-step explanation:

we know that

The roots of the quadratic function (x-intercepts) are

x=-1 and x=5/3

so

we can write the equation of the parabola as

$y=a(x+1)(x-\frac{5}{3})$

where

a is a coefficient

Remember that

The parabola pass through the point (5,40)

substitute the value of x and the value of y of the ordered pair in the quadratic equation and solve for a

x=5, y=40

$40=a(5+1)(5-\frac{5}{3})$

$40=a(6)(\frac{10}{3})$

$40=20a\\a=2$

substitute

$y=2(x+1)(x-\frac{5}{3})$

apply distributive property

$y=2(x^2-\frac{5}{3}x+x-\frac{5}{3})\\\\y=2(x^2-\frac{2}{3}x-\frac{5}{3})\\\\y=2x^2-\frac{4}{3}x-\frac{10}{3}$
