$(x-h)^2+(y-k)^2=r^2\\
(h,k)-\text{ center}\\\\
x^2+y^2-6x+8y+21=0\\
x^2-6x+9+y^2+8y+16-4=0\\
(x-3)^2+(y+4)^2=4\\
\text{center}=(3,-4)\\
r=\sqrt4=2$

solong [7]

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

I don't know for sure, but there are a bunch of different options. Here they are:

Step-by-step explanation:

1 + 39

2 + 38

3 + 37

4 + 36

5 + 35

6 + 34

7 + 33

8 + 32

9 + 31

10 + 30

11 + 29

12 + 28

13 + 27

14 + 26

15 + 25

16 + 24

17 + 23

18 + 22

19 + 21

20 + 20

Those are the options of how many volcanoes that they could have visited. They could have visited 23 volcanoes in Alaska and 17 in California. Who knows?

California only has 20 volcanoes, and Alaska has 40, so your answer will be one of these options. Hope this helps!

The article on the next page from the San Francisco Chronicle, January 27, 1996, describes very serious problems of subsidence,

Mekhanik [1.2K]

Answer:

246.3%

the complete question is found in the attached document

Step-by-step explanation:

1st step:

using 1936 data,

w1= 356% = 3.56(356/100) , H= 79 feet

specific gravity = 2.65

Sₓ= 100%= 1

initial void ratio(e₀)= (w1 x specific gravity)/Sₓ

=3.56 x 2.65/1 = 9.434

2nd step

using 1996 data

ΔH= 22ft

ΔH/H = Δe/(1 + e₀)

22/79 = Δe/(1+9.434)

0.278=Δe/10.434

Δe= 0.278 x 10.434

Δe= 2.905

Δe= e₀ - eₓ

eₓ= e₀-Δe

eₓ= 9.434 - 2.905

eₓ= 6.529

3rd step

calculating water content in 1996

eₓ =6.529, specific gravity= 2.65, Sₓ= 100%

W2 X 2.65 = 1 x 6.529

w2 = 6.529/2.65 = 2.463 = 246.3%

(sin (x+y)) / sinxcosy = 1+ cot(x) + tan(y)

ivann1987 [24]

Answer:

sin (×+y)/sinx cosy =1+ cotx tany

from trig ratio Sin [x +y] = sinx Cosy + cosx siny

Sinx cosy + cosox siny./Sinx cosy
