3) WILL MARK BRAINLIEST + 10 POINTS!!!!!! :)

Charra [1.4K]

This is really a long way to go to make something complicated
out of something simple. The last choice does the job.

cos(180) = -1
sin(180) = 0

So 4 [cos(180) + i sin(180) ]

= 4 [ -1 + i (0) ]

= -4 yay!

PLEASE I need help on these 4 problems you don’t have to do them all but if you can at least do one of them TYSM

Answer:

For right angle triangle,

we use Pythagoras theorem that is:

$c^{2} =a^{2} +b^{2}$

c = $\sqrt{a^{2} +b^{2} }$

For question 1:

c = ?

a = 40

b = 9

putting them in formula,

c = $\sqrt{40^{2} + 9^{2} }$

c = 41

For question 2:

c = ?

a = 12

b = 13

putting them in formula,

c = $\sqrt{12^{2} + 13^{2} }$

c = approximately 17.69181

For question 3:

c = 35

a = 20

b = ?

putting them in formula,

$c^{2} =a^{2} +b^{2}$

$35^{2} = 20^{2} + b^{2}$

1225 = 400 + $b^{2}$

$b^{2}$ = 1225 - 400

$b^{2}$ = 825

$\sqrt{b^{2} } = \sqrt{825}$

b = 5 $\sqrt{33}$

For question 4:

c = 37

a = 20

b = ?

putting them in formula,

$c^{2} =a^{2} +b^{2}$

$37^{2} = 20^{2} + b^{2}$

1369 = 400 + $b^{2}$

$b^{2}$ = 1369 - 400

$b^{2}$ = 969

Taking square root on both sides

b = 31.12

Hope it helps.

if the equation y equals 1/5 x + 2 is changed to y equals 1/5 x - 4 how will the graph of the line change

Taya2010 [7]

Answer:

if the equation y equals 1/5 x + 2 is changed to y equals 1/5 x - 4, then the graph of the line will translate 6 units downwards.
