Answer:
x^2+2xh+h^2+2
Step-by-step explanation:
F(x+h)=(x+h)^2+2 = x^2+2xh+h^2+2.
Answer:
The area of the circle with a radius of 5 cm is 78.5
π·5^2=78.5
Answer:
We can treat it like a triangle. The line from home plate bisects the 1st base
and 3rd base angle; so it's 45 degrees; call it angle B. The side opposite, b is
the side we want to find, (from 1st to dead center)
:
Let angle A be at 1st base then side a = 401
Let angle C is at center field, then side c = 90
:
Use the law of cosines:
b^2 = a^2 + c^2 - 2(a*c)Cos(B)
:
b^2 = 401^2 + 90^2 - 2(401*90)Cos(45)
:
b^2 = 16080 + 8100 - 2(36090)*.7071
:
b^2 = 168901 - 51038.5
:
b = √117863
b = 343.3 ft from 1st to straight-a-away center
Answer:
x=-0.5, y=3.5
Step-by-step explanation:
The system consists of two functions equations.
Plot graph of each function (see attached diagram for details).
These graphs intersect at one common point. Its coordinates approximately are (-0.454,3.546).
This common point represents the solution of given system. The answer rounded to the nearest tenth is x=-0.5, y=3.5.
