F(x)=1-x² and g(x)=√(11-4x)
(g+f)(2)=>
1-(2)²+√(11-4(2))
=√3-3
(f/g)(-1)
(1-(-1)²)/(√(11-4(-1))
=0
(g-f)(-1)
√(11-4*-1)-(1-(-1)²
=√15
(g×f)(2)
1-(2)²×√(11-4(2))
-3√3
Answer:
58 square units
Step-by-step explanation:
Take the shaded figure as a full larger rectangle minus the rectangular part which is not shaded.
Area of the full larger rectangle:
Area = length × width
Length = |12 - 2| = 10 units
Width = |8 - 1| = 7 units
Area = 10 × 7 = 70 units²
Area of the unshaded small rectangle:
Length = |10 - 4| = 6 units
Width = |3 - 1| = 2 units
Area = 6 × 2 = 12 units²
Area of the shaded figure = 70 - 12 = 58 square units
Answer:
Step-by-step explanation:
x^2=+5X=300
Let
x = the width of the rectangle
y = the length of the rectangle
we know that
the area of the rectangle is equal to
A=xy ___ equation 1
y=x+5 ___equation 2
substitute equation 2 in equation 1
------> given problem
so
the area of the rectangle is equal to
Solve the quadratic equation
we know that
The formula to solve a quadratic equation of the form is equal to
we have
so
substitute in the formula
The solution is
Find the value of y
y=x+5
