Answer:
The final price of money of t shirt that I own = $ 16.69
Step-by-step explanation:
Given in question as ,
The t shirt cost to the owner = $12
The markup percentage = 30%
So, now the cost price of t shirt = 30% of 12 + 12
= 3.6 + 12 = $15.6
Tax which is added now = 7%
So, new cost of t shirt = 7% of 15.6 + 15.6
= 1.092 + 15.6 =$ 16.69
Hence , the final price of money of t shirt that I own = $ 16.69 Answer
First you need to divide the area by pi. Then take that answer and square-root it. Your answer should come out to about 3.2 is the radius.
Answer:
yea only ofc
Step-by-step explanation:
Answer:
Two complex roots.
Step-by-step explanation:
F(x)=2x^4 +5x^3 - x^2 +6x-1
is a polynomial in x of degree 4.
Hence F(x) has 4 roots. There can be 0 or 2 or 4 complex roots to this polynomial since complex roots occur in conjugate pairs.
Use remainder theorem to find the roots of the polynomial.
F(0) = -1 and F(1) = 2+5-1+6-1 = 11>0
There is a change of sign in F from 0 to 1
Thus there is a real root between 0 and 1.
Similarly by trial and error let us find other real root.
F(-3) = -1 and F(-4) = 94
SInce there is a change of sign, from -4 to -3 there exists a real root between -3 and -4.
Other two roots are complex roots since no other place F changes its sign
