Answer:

r=3

Step-by-step explanation:

  • The equation of a circumference is (x-a)^2+(y-b)^2=r^2.
  • Then , in this case r^2=9, and then to know the value of r we just simply have to calculate the square root of 9, which is 3.

Solve the formula for x.<br> S=2πzx+7πz2
Lubov Fominskaja [6]

Answer:

<u>Given:</u>

  • S = 2πzx + 7πz²

<u>Isolate x:</u>

  • 2πzx = S - 7πz²

<u>Divide both sides by 2πz:</u>

  • x = (S - 7πz²)/(2πz)
  • x = S/(2πz) - 3.5z

How are the graphs of the functions f(x) = √16^x and g(x) =3√64^x related?
liberstina [14]

Answer:- The functions f(x) and g(x) are equivalent.


Explanation:-

Given functions:- f(x)=\sqrt{16^x} and g(x)=\sqrt[3]{64^x }

Simplify the functions by using law of exponents

(a^n)^m=a^{nm}

Thus f(x)=\sqrt{16^x}=\sqrt{(4^2)^x}=\sqrt{4^{2x}} =\sqrt{(4^x)^2}=4^x

and g(x)=\sqrt[3]{64^x}=\sqrt[3]{(4^3)^x}= \sqrt[3]{4^{3x}}= \sqrt[3]{(4^x)^3}=4^x

⇒f(x)=g(x)

Therefore ,the functions f(x) and g(x) are equivalent.

Very confusing help i dont understand
jasenka [17]

Answer:

12.8 servings

Step-by-step explanation:

1\frac{1}{4} cups of milk is used to make 10 servings of a recipe.

If 1\frac{1}{4} cups or \frac{5}{4} cups of milk is used to to make 1 serving.

Then 1 cup of milk will be required to make servings = \frac{1}{\frac{5}{4}}

                                                                                        = \frac{4}{5}

Since, 1 gallon = 16 cups

Therefore, 16 cups of milk will be required for servings = \frac{4}{5}\times 16

                                                                                            = 12.8 servings
