Scientific notation is always between 1-10 times 10 to the power of how many decimal points it needs to be moved over

So the first number would be 9.25*10^-4. You can figure out the power by just moving the decimal over and count until the number is between 1 and 10

If (x - h) = 4 and (y - k) = 3, what is the radius of the circle above?
I am Lyosha [343]
(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

AnnZ [28]
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 :)

Explain which situation will give you the best price: a discount of 15% and then 10% off that amount, a discount of 10% and then
Katarina [22]

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

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

Hence, the finial price is 76.5% of the initial price.

#Given a discount of 25%

P_1=(1-d)X\\\\=(1-0.25)X\\\\=0.75X

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.
