1,7
Step-by-step explanation:
x1 y1 x2 y2
5 , 11 -3 , 4
,
, = 1,7
Answer:
Dividing both sides of 5x = 4 by 5 yields x = 4 _. 5 . The value of x can now be ... tuting −1 for a into the equation b = –a + 3 gives b = −(−1) + 3, or b = 4. ... ___. 82 − (2i)2 . Since i2 = −1, this can be simplified to 24 − 6i − 40i − 10. __.

Answer:
c =1/2
Step-by-step explanation:
2(3–5c) = 4(1–c) -1
Distribute
6 - 10c = 4 -4c -1
Combine like terms
6 - 10c =3 -4c
Add 10c to each side
6-10c+10c = 3 -4c+10c
6 = 3+6c
Subtract 3 from each side
6-3 = 3-3+6c
3 = 6c
Divide by 6
3/6 =6c/6
1/2 =c
Answer:
value of gold is $33.17
Step-by-step explanation:
given data
depth d = 3800 m = 3.8 km
area A = 3.63 × 10^8 km²
average concentration = 5.8 × 10^−9 g/L
price of gold = $129.00 / troy oz
to find out
value of gold
solution
first we find volume that is
volume v = A× d
put here value
volume = 3.8 × 3.63 × 10^8
volume = 13.794 × km³
volume = 137.94 × L
so mass = 5.8 × × 137.94 ×
mass = 8 × g
mass = 0.2572 troy oz
here we know 1 troy oz = 31.1 g
and we know 1 troy oz = $129
so 0.2572 troy oz = 129 × 0.2572
0.2572 troy oz value is $33.17
value of gold is $33.17
