Eliza bought a meal that cost $12.00. She tipped the waiter 25%of that amount . How much was the tip ?

nignag [31]

You want to find 25% of $12. 25% also equals 1/4. 1/4 of 12 (or 12 divided by 4) is $3.

If AABC = ADEC, ZB = x + 15 and ZE = 6x - 65 B С x = [?] Enter Answer

miv72 [106K]

Answer:

x = 16

Step-by-step explanation:

Since the triangles are congruent then corresponding angles are congruent, that is

∠ B = ∠ E , substitute values

x + 15 = 6x - 65 ( subtract 6x from both sides )

- 5x + 15 = - 65 ( subtract 15 from both sides )

- 5x = - 80 ( divide both sides by - 5 )

x = 16

Use the polar representation to write the following in the form a + bi (a) (-1+ i)^7 (b) (1+v3i)^10

ira [324]

Answer with Step-by-step explanation:

For any complex number x+iy the polar form is represented as

$z=re^{i\theta }$

where

$r^{2}=x^2+y^2\\\\tan(\theta )=\frac{y}{x}$

Part a) x+iy = -1+i

Thus $r=\sqrt{-1^2+1^2}=\sqrt{2}\\\\ \theta _{1}=tan^{-1}(\frac{-1}{1})=\frac{-\pi }{4}$

Thus using De-Morvier's theorem

$(-1+i)^7=(\sqrt{2}e^{i\frac{-\pi }{4}})^7\\\\\therefore (-1+i)^7=2^{7/2}\cdot e^{\frac{i-\pi }{28}}$

Part 2) x+iy = 1+3i

Thus $r=\sqrt{1^2+3^2}=\sqrt{10}\\\\ \theta _{1}=tan^{-1}(\frac{3}{1})=1.25$

Thus using De-Morvier's theorem

$(1+3i)^{10}=(\sqrt{10}e^{1.25i})^{10}\\\\\therefore (1+3i)^{10}=10^{5}\cdot e^{12.5i}$
