(x-h)²+(y-k)²=r² is the equation of a circle with radius of r
so if x-h=4 and y-k=3 then
4²+3²=r²
16+9=r²
25=r²
sqrt both sides
5=r
radius is 5 units
1a=3.04
2a=30.4
3a=304
4a=3040
Answer:
x⁴ + 6x² + 9
Explanation:
To answer this question, we will multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final expression.
This can be done as follows:
(x² + 3)(x² + 3)
x²(x²) + x²(3) + 3(x²) + 3(3)
x⁴ + 3x² + 3x² + 9
x⁴ + 6x² + 9
Hope this helps :)
I believe the answer is 3/8, if i'm wrong then i really sorry
Answer:
Step-by-step explanation:
Let X be the initial price and P be the final price.
#Given a discount of 15% then 10% of that amount:
![P_1=(1-o)[X(1-d)}\\\\=(1-0.15)[X(1-0.10)]\\\\=0.765X](https://tex.z-dn.net/?f=P_1%3D%281-o%29%5BX%281-d%29%7D%5C%5C%5C%5C%3D%281-0.15%29%5BX%281-0.10%29%5D%5C%5C%5C%5C%3D0.765X)
Hence, the finial price is 76.5% of the initial price.
#Given a discount of 10% then 15% of that amount:
![P_1=(1-o)[X(1-d)}\\\\=(1-0.15)[X(1-0.1)]\\\\=0.765X](https://tex.z-dn.net/?f=P_1%3D%281-o%29%5BX%281-d%29%7D%5C%5C%5C%5C%3D%281-0.15%29%5BX%281-0.1%29%5D%5C%5C%5C%5C%3D0.765X)
Hence, the finial price is 76.5% of the initial price.
#Given a discount of 25%

Hence, the finial price is 75.0% of the initial price. It therefore give's the best price due to it's 25% price reduction.
