Answer:
Step-by-step explanation:
walks 3 miles in=45 min
1 mile in=45/3=15 minutes
26 miles=26×15=390 min.=6hrs 30 minutes
Answer:
5/3 x + 4 = 2/3 x Multiplying both sides by 3
5 x + 12 = 2 x
3x = -12
x = -4
Step-by-step explanation:
Answer:
Y≈4.6
Step-by-step explanation:
Because the hypotenuse is 9rad2 and the angle opposite of it is a 90. You can deduce it is a 90-45-45. From this you can tell the legs are 9. You then do 9 tan 26 to get about 4.4, and after this you subtract it from 9.
Answer:
10 units
Step-by-step explanation:
<u>General equation of an ellipse</u>
<u>Major Axis</u>: longest diameter of an ellipse
<u>Minor Axis</u>: shortest diameter of an ellipse
<u>Major radius</u>: one half of the major axis
<u>Minor radius</u>: one half of the minor axis
If a > b the ellipse is horizontal, a is the major radius, and b is the minor radius.
If b > a the ellipse is vertical and b is the major radius, and a is the minor radius.
Given equation:
Comparing with the general equation:
- h = 0
- a² = 9 ⇒ a = 3
- k = 4
- b² = 25 ⇒ b = 5
As b > a then the ellipse is vertical and b is the major radius.
⇒ Major axis = 2 × Major Radius
= 2b
= 2 × 5
= 10
Also, the vertices are:
- (3, 4) and (-3 ,4)
- (0, 9) and (0, -1)
