Your diagram implies x = 150 & r = √ ( x² + y² )
Answer:
6z + 9
Step-by-step explanation:
distribute 3/4 by 8z to get 6z
distribute 3/4 by 12 to get 9
Answer:
Approximately , there are 233 animals in the forest.
Step-by-step explanation:
There was a capture program of animals to get a count of the animals in that region.There were two rounds for that program. In the first round 70 animals were captured and all of them were tagged . In the second round , there were more animals caught but only 30% of those newly caught animals had tags.
Here we have to assume that no animal loses tag.
Let the total population be x .
Then 30% of the total population is 70.
Writing equation ,
x =233 animals
Approximately , there are 233 animals in the forest.
Answer:
103.65 mph
Step-by-step explanation:
A bearing of 250 deg is 200 deg on the coordinate plane.
Find the x- and y-components of the speed vectors. Add them. Then find the magnitude of the resultant.
Hx = 110 cos 200° = -103.366
Hy = 110 sin 200° = -37.622
Ax = 0
Ay = 30
Hx + Ax = -103.366
Hy + Ay = -37.622 + 30 = -7.622
sqrt(-103.366^2 + -7.622^2) = 103.65
Answer: 103.65 mph
Answer:
f^-1 (x) = 1/5 x +2
Step-by-step explanation:
To find the inverse exchange x and y and solve for y
y = 5x-10
Exchange x and y
x =5y-10
Solve for y
Add 10 to each side
x+10 = 5y-10+10
x+10 = 5y
Divide by 5
(x+10)/5 = 5y/5
(x+10)/5 = y
The inverse
f^-1 (x) = (x+10)/5
f^-1 (x) = 1/5 x +2
