Www.mathcentre.ac.uk/resources/uploaded/mc-ty-polynomial-2009-1.pdf<span>f(x)=4x3. − 3x. 2 + 2 is a polynomial of degree 3, as 3 is the highest power of x in the formula. This is called a cubic polynomial, or just a cubic.

Given P equals $11260, T equals six years, and R equals 7.5% compounded weekly. Use the correct compound interest formula to cal
Dmitrij [34]

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

where

A = total amount in the account at the end of t years

r represents the interest rate

n represents the periodic interval at which it was compounded

p represents the principal or initial amount deposited

From the information given,

P = 11260

t = 6

r = 7.5/100 = 0.075

n = 52(Assuming the number of weeks in a year is 52 and it would be compounded 52 times in a year)

Thus, we have

A = 11260(1 + 0.075/52)^52*6

A = 11260(1 + 0.075/52)^312

A = 17653.5

Explain how to use multiplication to find
Sindrei [870]

A fraction x/y is a ratio between two numbers x and y.

The ratio is preserved if both x and y are scaled up or down by the same number n.

This means you can obtain any fraction equivalent to x/y by multiplying both x and y by n, i.e. (n*x)/(n*y).

Then we have 1/4 = (2*1)/(2*4) = 2/8, for example.

How do you find the y-intercept of a line?
pogonyaev

The equation of any straight line, called a linear equation, can be written as: y= mx+b, where my is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the lone crosses the y axis.
