Step-by-step explanation:
y = 2kx², where k is a real constant.
We have:
2k(1)² - 2k(3)² = 32 or 2k(3)² - 2k(1)² = 32.
=> 2k - 18k = 32 or 18k - 2k = 32
=> -16k = 32 or 16k = 32
=> k = -2 or k = 2.
When x = -2,
y = 2(-2)(-2)² or y = 2(2)(-2)².
=> y = -16 or y = 16.
Answer:
It would be 15 inches.
Step-by-step explanation:
Because the windows have to have the same area, you would have to make the base x height equal to 90. 90 divided by 6 is 15
Bike to work: d=16*t
ride home: d = 27*.4 =10.8
solve for t
10.8 = 16*t
t = 10.8/16
0.7 of an hour
Answer:
C. FE and ED
Step-by-step explanation:
The question is asking what are the sides of angle E. I've marked angle E along with its sides in the attached picture.
One side of the angle E has to be ED.
However we have multiple options for the other side. It can be called FE, CE or BE.
So the answers could be any of:
- ED and FE
- ED and CE
- ED and BE
The option that has one of the possible answers is option C: FE and ED.
