F(x) = 49 − x2 from x = 1 to x = 7; 4 subintervals
Setler [38]

Answe

Given,

f(x) = 49 − x² from x = 1 to x = 7

n = 4

\Delta x = \dfrac{7-1}{4}= 1.5

For x= 1

f(x₀) = 49 - 1^2 = 48

x = 2.5

f(x₁) = 42.75

x = 4

f(x₂) = 49 - 4^2 = 33

x = 5.5

f(x₃) = 49 - 5.5^2 = 18.75

x = 7

f(x₄) = 49 - 7^2 = 0

We have to evaluate the function on therigh hand point

A = \Delta x [f(x_1)+f(x_2)+f(x_3)+f(x_4)]

A = 1.5 [42.75+33+18.75+0]

A = 141.75

For Area for left hand sum

A = \Delta x [f(x_0)+f(x_1)+f(x_2)+f(x_3)]

A = 1.5 [48+42.75+33+18.75]

A =213.75

Convert the following complex number into its polar representation: 2-2sqrt3i
Rufina [12.5K]

Answer:

  C.  4(cos(300°) +i·sin(300°))

Step-by-step explanation:

The magnitude will be ...

  magnitude = √(2^2 +(-2√3)^2) = √(4+12) = 4

The negative imaginary part puts the angle in the 4th quadrant. The answer choice with a magnitude of 4 and a 4th-quadrant angle is ...

  4(cos(300°) +i·sin(300°))

__

If you want to figure the angle, it will be ...

  angle = arctan(Im()/Re()) = arctan(-2√3/2) = arctan(-√3) = -60°

The corresponding 4th-quadrant angle is 300°.

_____

<em>Comment on answer choices</em>

Answer choice A is <em>another representation of the same number</em>. Typically, we want the magnitude to be positive in polar form, so that answer can be avoided on those grounds.
