7-11x= -114
Subtract 7 from -114 = -121
Divide -121 by -11 = 11
x=11
Answer: James
Step-by-step explanation:
0.17M is bigger than 0.165.
Since if you subtract
0.170 - 0.165 = 0.005
There is 0.005 difference.
Answer:
the value of both expressions when t = 3 is 33
the value of both expressions when t = 6 is 51
Step-by-step explanation:
33 33
51 51
The foci of an ellipse are (c,0) & (-c,0)
Where c² = a² - b²
The major axis is 34 feet
So 2a = 34
Dividing by 2 on both sides
a = 17
Also minor axis is 16 feet
So 2b = 16
Dividing by 2 on both sides
b = 8
Now we know
c² = a² - b²
c² = 17² - 8² = 289 - 64 = 225
Taking square root on both sides
c = 15 feet
Now the two foci are (15,0) & (-15,0)
Distance between these points is 15 - (-15) = 15 + 15 = 30
The distance between the two foci is 30 feet.
