Step-by-step explanation:
<u>The Polynomial Remainder Theorem</u>
It states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).
We have the polynomial:
And we need to determine if x=1 and/or x=-1 are zeros of the polynomial.
Considering the polynomial remainder theorem, if we try any value for x, and the remainder is zero, then that value of x is a root or zero of the polynomial.
Find:
f(1)=4
Thus, x=1 is not a zero of f(x)
Now, find:
Thus, x=-1 is a zero of f(x)
Answer: -1
Answer:
The trigonometric ratios can be found by looking at the ratios of a right triangles sides. Sin is opposite:hypotenuse, cos is adjacent:hypotenuse, and tan is opposite

Step-by-step explanation:
4 = Red
3 = Blue
2 = White
1 = Yellow
What is probability that it is not yellow ?
Because only 1 marble is yellow and they are 9 other colours apart from yellow it must be
A) 0.3413 . . . . the area from -1 to 0 is the same as the area from 0 to 1. The normal curve is symmetrical about x=0.
b) 0.3413 . . . . A(1) on the chart
c) 0.4772 . . . . A(2) on the chart
d) 0.4987 . . . . A(3) on the chart
e) 0.3413 + 0.4772 = 0.8185 . . . . A(1)+A(2) on the chart
Answer:
After 12 years the investment will be worth $5145.
Step-by-step explanation:
The formula used for compounded interest is:
A = P(1+r/n)^nt
where,
A = future value
P = Principal Amount
r = interest rate
n = no of times interest is compounded
t = time
In the question given:
A=?
P = $2100
r = 7.75% or 0.0775
n = 1
t= 12
A= 2100*(1+0.0775/1)^1*12
A= 2100 *(1+0.0775)^12
A= 2100 *(1.0775)^12
A= 2100 * 2.45
A= 5145
So, after 12 years the investment will be worth $5145.
