Answer:
Area of regular pentagon is 238.95 square inches.
Step-by-step explanation:
Given a regular pentagon with side length of 11.8 inches and dotted line from center to middle of side of 8.1 inches.
we know a regular polygon divides into 5 congruent triangles.
Side of pentagon i.e base of one triangle is 11.8 inches.
Also, distance from center to middle of side which is height of triangle is 8.1 inches.
Area of 1 triangle= 
= 
= 47.79 sq inches.
Area of regular pentagon=area of 5 congruent triangles= 
=238.95 sq inches.
Answer:
$7,440.
Step-by-step explanation:
$0-$11,000 = no tax.
$11,000-$43,000 = 20%.
$43,000-$150,000 = 40%.
The earnings over $150,000 = 45%. etc....
$45,600, = Revenue
Tax is 11000-43000 is = 0.20 * (32000)
= 11000-43000 = 6400
Tax is 43000-45,600 is = 0.40 *(2600)
= 45,600-43000 = 1040
=6400+1040 =7440
Answer:
Inequality Form:
x
>
7
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
x can be anything bigger then 7 to make this true.
Quadratic equations are also used when gravity is involved, such as the path of a ball or the shape of cables in a suspension bridge. A very common and easy-to-understand application of a quadratic function is the trajectory followed by objects thrown upward at an angle.
