Consider the graph of the sixth-degree polynomial function f.
vekshin1

Answer:

b = 1, c = -1 and d = 4

Step-by-step explanation:

To solve this question the rule of multiplicity of a polynomial is to be followed.

If the multiplicity of a polynomial is even at a point, graph of the polynomial will touch the x-axis.

If the multiplicity of the polynomial is odd, graph will cross the x-axis at that point.

From the graph of function 'f',

f(x) = (x - b)(x - c)²(x - d)³

Since, graph of the function 'f' crosses x-axis at x = 1 and x = 4, multiplicity will be odd and touches the x-axis at x = -1 multiplicity will be even.

So the function will be,

f(x) = (x - 1)[x - (-1)]²(x - 4)³

Therefore, b = 1, c = -1 and d = 4 will be the answer.

A tennis club has 560 members.
enyata [817]

Answer:

see explanation

Step-by-step explanation:

sum the parts of the ratio, 5 + 6 + 3 = 14 parts

Divide number of members by 14 to find the value of one part of the ratio.

560 ÷ 14 = 40 ← value of 1 part of the ratio

(i)

number of women = 6 × 40 = 240

(ii)

number of children = 3 × 40 = 120

The monthly revenue of a certain company is given by R 820p-7p, where p is the price in dollars of the product the company manuf
lora16 [44]

The revenue will be 12,000 when the price of the product  is $100

Given :

The monthly revenue of a certain company

R=820p-7p^2

We need to find out p when <u>Revenue R is 12000</u>

Lets replace R with 12000 and solve for p

12000=820p-7p^2\\820p-7p^2=12000\\-7p^2+820p-12000=0

Apply <em>quadratic formula </em>

p=\frac{-820\pm \sqrt{820^2-4\left(-7\right)\left(-12000\right)}}{2\left(-7\right)}\\p=\frac{-820\pm \:580}{2\left(-7\right)}\\p=\frac{-820+580}{2\left(-7\right)},\:p=\frac{-820-580}{2\left(-7\right)}\\p=\frac{120}{7},\:p=100

Given that price must be greater than 50

So the revenue will be 12000 when the price of the product  is $100

Basic Power Rule:

  • f(x) = cxⁿ
  • f’(x) = c·nxⁿ⁻¹

Derivative Rule [Chain Rule]:                                                                                    \displaystyle \frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em />\displaystyle y = (x + \sqrt{x})^2<em />

<em />

<u>Step 2: Differentiate</u>

  1. Chain Rule:                                                                                                        \displaystyle y' = 2(x + \sqrt{x})^{2 - 1} \cdot \frac{d}{dx}[x + \sqrt{x}]
  2. Rewrite [Exponential Rule - Root Rewrite]:                                                     \displaystyle y' = 2(x + x^{\frac{1}{2}})^{2 - 1} \cdot \frac{d}{dx}[x + x^{\frac{1}{2}}]

  6. Rewrite [Exponential Rule - Rewrite]:                                                              \displaystyle y' = 2(x + x^{\frac{1}{2}}) \cdot (1 + \frac{1}{2x^{\frac{1}{2}}})
