What is the area of trapezoid ABCD?

Mathematics

Determine the measure of bases a and b and height h of the given trapezoid. Given the coordinates of the points, the distance is calculated through the equation,

     d =  sqrt ((x₂ - x₁)² + (y₂ - y₁)²)

Base 1: (-2,2) and (1,-2):
    d= sqrt ((-2 - 1)² + (2 - -2)²) = 5

Base 2: (2,5) and (11, -7)
   d = sqrt ((2 - 11)² + (5 - -7)²) = 15

Height: (-2,2) and (2, 5)
   h = sqrt ((-2 -2)² + (2 - 5)²) = 5

The equation for the area of the trapezoid is,
    A = (1/2)(base1 + base2)h

Substituting the known values,
   A = (1/2)(5 + 15)(5) = 50

ANSWER: 50 square units

If f(y) = e^(9y) + e^(-9y), find f'(y). Use exact values.
Westkost [7]

Given:

f(y)=e^{9y}+e^{-9y}

To find:

The f'(y).

Solution:

Chain rule of differentiation:

[f(g(x))]'=f'(g(x))g'(x)

Differentiation of exponential:

\dfrac{d}{dx}e^x=e^x

We have,

f(y)=e^{9y}+e^{-9y}

Differentiate with respect to y.

f'(y)=e^{9y}\dfrac{d}{dx}(9y)+e^{-9y}\dfrac{d}{dx}(-9y)

f'(y)=e^{9y}\cdot 9(1)+e^{-9y}\cdot (-9)(1)

f'(y)=9e^{9y}-9e^{-9y}

Therefore, the differentiation of the given function is f'(y)=9e^{9y}-9e^{-9y}.

Number one is really confusing
erik [133]

Answer:

7% tax is $1.46

Step-by-step explanation:

When you pay 7% tax, this means that you are adding on 7% of $20.89 to $20.89:

20.89+(0.07)(20.89)

20.89+1.46

22.35

This means that 7% tax is $1.46 and the total price including tax would be $22.35
