Answer:

Slope (m) = -⁵/4

y-intercept (b) = 1.5

The graph is non-proportional

Step-by-step explanation:

The slope of a graph using the points, (-2, 4) and (2, -1) is calculated as:

m = \frac{y_2 - y_1}{x_2 -x_1} = \frac{-1 - 4}{2 -(-2)} = \frac{-5}{4}

✅Slope (m) = -⁵/4

✅y-intercept (y) is the point at which the line intercepts the y-axis = 1.5

✅A proportional graph usually has a line that runs through the point of origin (0, 0). Therefore, the graph is non-proportional.

the volume of hemisphere is 1527.4cm^3.find the radius of the hemisphere to the nearest whole whole number.(take π to be 22/7)​
skelet666 [1.2K]

Answer:

radius of the hemisphere = 9 cm approx

Step-by-step explanation:

Volume of hemisphere = \frac{2}{3} \pi r^{3}

1527.4 = \frac{2}{3} * \frac{22}{7} * r^{3}

\frac{7*15274*3}{2*22*10} = r^{3}

\frac{320754}{440} = r^{3}

r^{3} = 729

r = \sqrt[3]{729}

r = 9 cm approx.

Answer:

\displaystyle f'(x) = \frac{4}{x^2}

General Formulas and Concepts:

<u>Calculus</u>

Limits

  • Limit Rule [Variable Direct Substitution]:                                                    \displaystyle \lim_{x \to c} x = c

Differentiation

  • Derivatives
  • Derivative Notation

The definition of a derivative is the slope of the tangent line:                             \displaystyle f'(x) = \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify.</em>

<em />\displaystyle f(x) = -\frac{4}{x}

<u>Step 2: Differentiate</u>

  1. [Function] Substitute in <em>x</em>:                                                                            \displaystyle f(x + h) = -\frac{4}{x + h}
  2. Substitute in functions [Definition of a Derivative]:                                   \displaystyle f'(x) = \lim_{h \to 0} \frac{-\frac{4}{x + h} - \big( -\frac{4}{x} \big)}{h}
  3. Simplify:                                                                                                        \displaystyle f'(x) = \lim_{h \to 0} \frac{4}{x(x+ h)}
  4. Evaluate limit [Limit Rule - Variable Direct Substitution]:                          \displaystyle f'(x) = \frac{4}{x(x+ 0)}
  5. Simplify:                                                                                                        \displaystyle f'(x) = \frac{4}{x^2}

∴ the derivative of the given function will be equal to 4 divided by x².

A video club charges $3 per movie rented. The total cost to rent 4 videos was $22. Write an equation in slope
Klio2033 [76]

Answer:

$3 to buy one movie and $22 to buy 4 movies well the fact is that they raise the price tag because it's either getting more popular or there doubling the price just because they can. So there is no right or wrong answer to this question.
