What is 3,989.23655 rounded to the nearest one thousandth?

1 answer:

8 0

The 6 is in the thousandth place so you round with that being the last number
since we have a 55 after the 6, we round up
so we get
3,989.237

The length of a rectangle is increasing at a rate of 6 cm/s and its width is increasing at a rate of 5 cm/s. When the length is

Rudiy27

Answer:

Area of the rectangle is increasing with the rate of 84 cm/s.

Step-by-step explanation:

Let l represents the length, w represents width, t represents time ( in seconds ) and A represents the area of the triangle,

Given,

$\frac{dl}{dt}=6\text{ cm per second}$

$\frac{dw}{dt}=5\text{ cm per second}$

Also, l = 12 cm and w = 4 cm,

We know that,

A = l × w,

Differentiating with respect to t,

$\frac{dA}{dt}=\frac{d}{dt}(l\times w)$

$=l\times \frac{dw}{dt}+w\times \frac{dl}{dt}$

By substituting the values,

$\frac{dA}{dt}=12\times 5+4\times 6$

$=60+24$

$=84$

Hence, the area of the rectangle is increasing with the rate of 84 cm/s.

Write a polynomial function of least degree with integral coefficients that have the given zeros. 4,-1,6 f(x)=x^3-9x^2+14x+24

AlladinOne [14]

Answer:

see explanation

Step-by-step explanation:

Given the zeros of a polynomial, say x = a, x = b, x = c

Then (x - a), (x - b), (x - c) are it's factors

and the polynomial is the product of the factors

here x = 4, x = - 1, x = 6, hence

(x - 4), (x + 1) and (x - 6) are the factors

f(x) = a(x - 4)(x + 1)(x - 6) ← a is a multiplier

let a = 1, then expanding the first pair of factors

f(x) = (x² - 3x - 4)(x - 6) ← expand out the factors

= x³ - 3x² - 4x - 6x² + 18x + 24 ← collect like terms

= x³ - 9x² + 14x + 24
