Answer:

  -625

Step-by-step explanation:

The magnitude gets raised to the power, and the angle gets multiplied by the power:

  5(cis7pi/4)^4 = (5^4)cis(4·7π/4) = 625cis(7π) = 625cis(π) = -625

Find the area of the figure.
shutvik [7]

Answer:

The height is 57.5

Step-by-step explanation:

To find the height, you would use the equation h= 2 a/a+b

So you would insert the numbers and turn the equation into 2(6555/ 123+105)

Then you would solve.

After solving, you will find that H= 57.5

Hope this helped! If it helped please give brainliest!

I will give a brainlist if someone could answer this problem with a explanation:)
egoroff_w [7]

Answer:

Step-by-step explanation:

The two base angles in each triangle are equal. (The triangle is isoceles and the property used is angles opposite equal sides are equal).

Now the tricky part. The peak angles are also equal. That's because both peak angles are made equal by Peak angle + 2*base angle = 180

Peak angle = 180 - 2*base angle

Therefore the triangles are congruent by SAS.  

I suppose you could get them equal by taking one of the base angles (all 4 are equal to each other) and the peak angles and claim equality by ASA, but it seems a little bit tortuous to me.

Pq has a length of 17 units with p(-4,7). If the x and y coordinates of q are both greater than the x and y coordinates of p wha
prisoha [69]

Answer:

Step-by-step explanation:

1²+16²=1+256=257≠289(17²)

2²+16²=4+256=260≠17²

3²+16²=9+256=265≠17²

4²+16²=16+256=272≠17²

5²+16²=25+256=281≠17²

6²+16²=36+256=292>17²

6²+15²=36+225=261≠17²

7²+15²=49+225=274≠17²

8²+15²=64+225=289=17²

9²+14²=81+196=277≠17²

10²+14^2=100+196>289

10²+13²=100+169=269≠17²

11²+13³=121+169=290>17²

11²+12²=121+144=265≠17²

12²+12²=144+144=288≠17²

so only integer values are 8²+15²=17²

(x+4)²+(y-7)²=17²

if x+4=8

x=8-4=4

y-7=15

y=15+7=22

so q is (4,22)

if x+4=15

x=15-4=11

y-7=8

y=8+7=15

point is (11,15)
