Find the limit of the function by using direct substitution. limit as x approaches three of quantity x squared plus three x minu
Inessa [10]

Answer:

17

Step-by-step explanation:

Given the limit of a function expressed as;

\lim_{x \to 3} x^2 + 3x - 1

Substitute x = 3 into the function to have;

= 3^2  + 3(3) - 1\\= 9 + 9 -1 \\= 18 - 1\\= 17

Hence the limit of the function as x tends to 3 is 17

What is the inverse of the function f(x) = x 3? h(x) = one-thirdx 3 h(x) = one-thirdx – 3 h(x) = x – 3 h(x) = x 3
riadik2000 [5.3K]

The inverse of the function f(x) = x^{3} is : \sqrt[3]{x}

<h3 /><h3>What is the inverse of a function?</h3>

The inverse of a function is that function that acts to undo a given function.

Analysis:

if f(x) = x^{3}, then let y = x^{3}

\sqrt[3]{y} = \sqrt[3]{x^{3} }

x = \sqrt[3]{y}

Replace y with x

h(x) = \sqrt[3]{x}

in conclusion, the inverse of h(x) = \sqrt[3]{x}

bulgar [2K]

<u>Answer:</u>

  • The numerator '9's share is 450 and the denominator '7's share is 350.

<u>Step-by-step explanation:</u>

<u>Step-1: Add the ratios:</u>

  • 9 + 7
  • 16

<u>Step-2: Divide 800 by the sum of the ratios:</u>

  • 800 ÷ 16
  • => 50

<u>Step-3: Multiply 50 with each ratio:</u>

  • 9 x 50 = 450
  • 7 x 50 = 350

Hence, <u>the numerator '9's share is 450 and the denominator '7's share is 350.</u>

Hoped this helped.

The volume of a sphere is approximately 44.6022 cubic centimeters. What is the radius of the sphere to the nearest tenth of a ce
Mumz [18]
The formula for the volume of a sphere is (4/3)*pi*r^3. Using this formula, we have 44.6022 cm^3 = (4/3)*pi*r^3. Solving for r, we get 2.2 cm. Thus, the radius of the sphere with an approximate volume of 44.6022 cubic centimeters is 2.2 cm. To add, the volume of a sphere is also exactly two-thirds the volume of its circumscribed cylinder.
