Answer:
radius is 7yd, height is 4 yd, v=3.14 x 7^2 x 4. The last one, I'm not too sure about but it might be V= 615.44^3
Step-by-step explanation:
The sale tax it's $0.07 for every $1 bc 2.94 divided by 42 =0.07 and 0.07•58=4.06 So the sales tax for an item that cost $58.00 is $4.06
Answer:
$420/5
$85 a day is Jesse's daily wage
Step-by-step explanation:
Suppose that the polynomial x^2+y^2-1 is not irreducible.
It means that there exists two fractions such that :

We found that q divide t and q divide s, but s and t are supposed to be prime each other. It is a contradiction.
The polynomial x^2+y^2-1 is then irreducible in q[x,y]
Answer:
No, the pair is not a solution to the equation.
Step-by-step explanation:
For the pair to be a solution to the equation, x = -2 must lead to y = 8, o =r vice versa. This leads to being able to solve it two ways either through x or through y.
I'll solve it through x:
y = -2x - 1
with x = -2
y = -2 * - 2 - 1
y = 4 - 1
y = 3
Since y = 3, when x = -2 the pair (-2,8) is not a pair to the solution of the equation.
PS: You can double check by solving through y and you'll find x = -4.5
