Answer:
y=sqrt(1/2x-25/2), -sqrt(1/2x-25/2).
Step-by-step explanation:
y=2x^2+25
x=2y^2+25
2y^2=x-25
y^2=1/2x-25/2
y=sqrt(1/2x-25/2), -sqrt(1/2x-25/2)
Answer:
9-2b should be your answer.
Answer:
6^3
Step-by-step explanation:
This Problem Is Actually Quite Simple If You Look. There Are 60 Minutes In One Hour. A Proportional Relationship Will Help.
10 60
---- = ---
1 X
10X = 60.
-------------
10 10
X = 6.
Since X = 6, That Means Richard Can Walk 6 kilometers In One Hour. :D

Answer: the distance of the base of the house to the foot of the ladder is 6.84 feet
Step-by-step explanation:
The scenario is shown in the attached photo.
Right angle triangle ABC is formed when the ladder leans against the wall of the house.
AC = the height of the ladder
AB = x feet = distance of the base of the house to the foot of the ladder
BC is the wall of the building.
To determine x, we will apply trigonometric ratio
Cos # = adjacent/hypotenuse
Where
# = 70 degrees
Hypotenuse = 20
Adjacent = x
Cos 70 = x/20
x = 20cos70
x = 20 × 0.3420
x = 6.84 feets
