Answer:
a.) because one month isn't very long
Step-by-step explanation:
let L = length and let W = width.
Use the equations 2L + 2W = 2750
and L = 5W + 15
Then do the steps as follows -
1. Plug the equation for what L equals into the first equation
2(5W+15) + 2W = 2750
2. Then distribute the 2
10W + 30 + 2W = 2750
3. Then add like terms
12W + 30 = 2750
4. Then subtract 30 from both sides
12W = 2720
5. Divide by 12 on both sides
W = 226.67
6. Then plug that into the second equation
L = 5(226.67) + 15
L = 1148.35 should be the answer
Answer:
4x4 - x3 + 7x2 + 13x - 10
Step-by-step explanation:
(((4•(x4))+7x2)+6x)-(x3-7x+10)
((22x4 + 7x2) + 6x) - (x3 - 7x + 10)
3.1 Find roots (zeroes) of : F(x) = 4x4-x3+7x2+13x-10
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 4 and the Trailing Constant is -10.
of the Leading Coefficient : 1,2 ,4
of the Trailing Constant : 1 ,2 ,5 ,10
Final result :
4x4 - x3 + 7x2 + 13x - 10
hope this helps:)sorry if it doesnt
1. I think is 4/5
2. Is 152
and
3. Is 1/12 (im not sure about this one)
Hope this helped!
Answer:
16= (x-4)^2 +(y+9)^2
Step-by-step explanation:
hey! The formula for the equation of a circle is r^2= (x-h)^2 + (y-k)^2
r= the radius (in your case you have the diameter so you do not need to square it)
(h,k)= is the center coordinates, so your center coordinate would be (4, -9). You now have your h (h=4) and your k (k=-9) so you can plug it in the formula! :)
a nice rating would help out
