Calculate the compound amount on rs 2000 for 3 years at the rate of 13% p.a

IrinaVladis [17]

A=P(1+r%)ⁿ , where P is the initial capital, r, the interest rate and n, the # years

A = 2000(1+0.13)³
A = 2000(1.13)³
A = 2,885.79

What is the discriminant of the quadratic equation 0 = –x2 4x – 2?

lyudmila [28]

The answer is down the page under ANSWER. here is a quick explanation first.

okay, i assume your equation is actually like this:

minus x squared plus 4 x minus

note: the proper way to type this electronically is: -x^2 + 4x - 2.

The equation you gave is known as a quadratic equation.

if you think about it, the generic (general) way of writing this quadratic equation is:

ax^2 + bx + c

a, b and c are just numbers

eg.

2x^2 + 7x + 4

looking at the general equation above

a is 2
b is 7
c is 4

you can put negatives in as well, to find out a, b and c

eg

-2x^2 - 6x - 12

so, what is a b and c?

a is -2 (must say its negative)
b is - 6 (must say negative)
c is - 12 ( again, remember its a negative number)

ANSWER

IF YOU JUST WANT THE ANSWER.

THE DISCRIMINANT IS:

4 squared minus (4 times -1 times -2)
this is 16 - 8
solution of discriminant is 8

explanation:

so, now we cleared that up.
in any quadratic equation ( like the equation you gave), the discriminant is (in general)

b2 - 4ac

use this to solve it for any quadratic equation for the discriminant

The data show the chest size and weight of several bears. Find the regression equation, letting chest size be the independent

Ipatiy [6.2K]

Answer:

y = 16.3216X - 330.3904

322 pounds;

Result is significant

Step-by-step explanation:

Given the data:

Chest size, x : 41,54,44,55,39,51

Weight, Y : 328,528,418,580,296,503

Using technology, the prediction model obtained by fitting the data is :

y = 16.3216X - 330.3904

Where, x = chest size ; y = weight

The best predicted weight of a bear with chest size of 40 is

Put x = 40 in the equation :

y = 16.3216(40) - 330.3904

Y = 322.4736

Y = 322 pounds

At α = 0.05

The regression Coefficient, R value obtained is 0.986 ; using this to obtain the Pvalue ;

df = n - 1

Pvalue(0.986, 5) = 0.00198

Since, Pvalue < α ; result is significant at α = 0.05

jim is reading a 303 page book hes already read 87 pages if he can read 12 pages in an hour how many more hours will it take him

Ne4ueva [31]

You would do 303 subtract 87. you get 216. 216/12 = 18 therefore it takes him 18 hours
