Ray Of Light [21]

Answer:

0.8

Step-by-step explanation:

Given,

Price of an item = X dollars

Discount = 20%

Amount of discount = 20% of Price of item

Amount of discount = \frac{20}{100}*X=0.2X10020∗X=0.2X

Price of item after discount = Price of item - Amount of discount

Price of item after discount = X-0.2X = 0.8X dollars

The discount price will be 0.8x dollars

A function f has derivatives of all orders for all real numbers, x. Assume f(2) = −3, f ′(2) = 5, f ″(2) = 3 and the third deriv
nadezda [96]

The Taylor polynomial would be

T_3(x)=f(2)+f'(2)(x-2)+\dfrac{f''(2)}2(x-2)^2+\dfrac{f'''(2)}6(x-2)^3

T_3(x)=-3+5(x-2)+\dfrac32(x-2)^2-\dfrac43(x-2)^3

Then

f(1.5)\approx T_3(1.5)=-\dfrac{119}{24}\approx-4.96

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is a leg
  • b is another leg
  • c is the hypotenuse

Step-by-step explanation:

<u>Step 1: Identify</u>

Leg <em>a</em> = 8

Leg <em>b</em> = 6

Hypotenuse <em>c</em> = <em>x</em>

<em />

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                    8² + 6² = x²
  2. Exponents:                          64 + 36 = x²
  3. Add:                                     100 = x²
  4. Isolate <em>x</em>:                              10 = x
  5. Rewrite:                                x = 10
