Answer:
A) Diameter = 9.03 ft
B) Circumference = 28.35 ft
Step-by-step explanation:
64 = πR²
R² = 64/3.14 = 20.38
Radius = 4.51 ft
Diameter = 2(4.51) = 9.03 ft
Circumference = 9.03 x 3.14 = 28.35 ft

f(x)=[tex]\sqrt{x^2-4}[/tex], x[tex]\leq \}[/tex]0
find [tex](f^-^1)'(1)[/tex]
I keep getting the wrong answer. The correct answer is[tex]\frac{1}{\sqrt{5} }[/tex]
Solve for x when √(x ² - 4) = 1 :
√(x ² - 4) = 1
x ² - 4 = 1
x ² = 5
x = ±√5
We're looking at x ≤ 0, so we take the negative square root, x = -√5.
This means f (-√5) = 1, or in terms of the inverse of f, we have f ⁻¹(1) = -√5.
Now apply the inverse function theorem:
If f(a) = b, then (f ⁻¹)'(b) = 1 / f '(a).
We have
f(x) = √(x ² - 4) → f '(x) = x / √(x ² - 4)
So if a = -√5 and b = 1, we get
(f ⁻¹)'(1) = 1 / f ' (-√5)
(f ⁻¹)'(1) = √((-√5)² - 4) / (-√5) = -1/√5
The sign must be negative; see the attached plot, and take note of the negatively-sloped tangent line to the inverse of f at x = 1.

Answer:
a = 3b = 4c = 2d = 1Step-by-step explanation:
There are zeros at x=-1 and x=4, so numerator factors of (x +1) and (x -4).
There are vertical asymptotes at x=1 and x = -2, so denominator factors of (x-1) and (x+2).
There is a hole at x=-3, so another numerator factor of (x+3) to cancel the one in the denominator.
Comparing the above to the given expression for f(x) we see that ...

[tex]\frac{\sqrt{24}- \sqrt{54} }{\sqrt{6}}[/tex] = -1 [tex]\sqrt{\frac{9}{20}[/tex]*[tex]\frac{10\sqrt{2} }{3\sqrt{5} }[/tex] = 1.4142[tex]\frac{10\pi\sqrt{2}-8\pi\sqrt{2}}{2\sqrt{2}}[/tex] = π =3.14159[tex]\pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}}[/tex] = π² = 9.8696Explanation:
1.) Rewrite √24 = [tex]\sqrt{4*6} = 2\sqrt{6}[/tex] Rewrite √54 =[tex]\sqrt{9*6}= 3\sqrt{6}[/tex]
Divide both terms by the denominator; √6 cancels. 2-3 = -1
2.) Rewrite as [tex]\frac{3}{2\sqrt{5}}[/tex] ×[tex]\frac{10\sqrt{2}}{3\sqrt{5}}[/tex] The 3's cancel. 10/2 = 5√2 in the numerator.
√5 × √5 = 5 in the denominator. The 5's cancel.
That leaves √2 ≈1.4142
3.) Divide the terms in the numerator by the term in the denominator.
√2's cancel. 10π/2 = 5π 8π/2 = 4π
Subtract and we are left with π = 3.14159
4.) [tex]\pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}}[/tex] The square roots are reciprocals. They multiply to 1
We are left with π × π = π² ≈ 9.8696

Convert the equation from vertex form to standard form.
Answer: pink one
Step-by-step explanation:
The convert form of vertex equation y = -3(x+5)² - 4 in standard equation is y = -3x² - 30x - 79.
What is vertex form of equation?The standard form of the equation is ax²+bx+c=y and the vertex form of the equation is y= a(x-h)²+k,
Where k is a constant.
The given equation is,
y = -3(x+5)² - 4
To convert this vertex form of equation is standard form,
Simplify,
y = -3(x²+ 25 + 10x) - 4
y = -3x² -75 - 30x - 4
y = -3x² - 30x - 79
The required standard form of equation is y = -3x² - 30x - 79.

Rewrite each subtraction equation as an addition equation.
p - 20 = - 30
Answer:
p + 30 = 20
Step-by-step explanation:
we can add 30 to both sides to make this an addition equation:
p - 20 = -30 (now add 30 to both sides)
p - 20 + 30 = 0 (then, add 20 to both sides)
p + 30 = 20 (this would be the addition equation)

xmin = 7.86
with cross multiplication;
xmin = 7.86*5min/2.90
