Ask Your Teacher Write out the form of the partial fraction decomposition of the function (See Example). Do not determine the nu
exis [7]

Answer:

Step-by-step explanation:

Given to ask the Teacher Write out the form of the partial fraction decomposition of the function

It is not necessary to find the coefficients

For decomposition of partial fractions the necessary condition is that the denominator should be in a position to be factored into atleast two factors.

Then only partial fraction is possible otherwise not.

Here

a) \frac{x}{x^2+x-20}

Denominator = x^2+x-20\\=(x+5)(x-4)

So this can be resolved into partial fractions as

\frac{x}{x^2+x-20}=\frac{A}{x+5}+ \frac{B}{x-4}

b) Here given

\frac{x^2}{x^2+x+2} \\=\frac{x^2+x+2-x-2}{x^2+x+2} \\=1-\frac{x+2}{x^2+x+2}

But denominator cannot be factored

So cannot be decomposed into partial fraction

PLEASE HELPP! The diameter of a decorated plate is 20 centimeters. There is a flower painted every 15.7 centimeters around the e
kirill115 [55]

Answer:

4 flowers

Step-by-step explanation:

First we need to calculate the circumference of the plate.

C = πd

Given

diameter d = 20cm

C = 3.14(20)

C = 62.8 cm

If there is a flower painted every 15.7 centimeters around the edge of the plate, the amount of flower on the plate will be;

Number of flower = Circumference of the plate/length of flower

Amount of flower = 62.8/15.7

Amount of flower = 4

Hence there are 4 flowers painted on the plate
