<span>Circumference of a circle = 2 π r
(where r is the radius)
Area of a circle = π r^2
(where r is the radius)
you have to find the radius
C = 2π unit
r = 1 unit
Area = π square units

Answer:
A quadratic Trinomial
Step-by-step explanation:
hope this helps
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
Answer:
y = 3
Step-by-step explanation:
2y - 3 = 
square both sides to remove sqrt bracket
(2y - 3)^2 = ( )^2
simplify both sides
(2y - 3)(2y - 3) = 
- 10y + 12
- 12y + 9 = - 10y + 12
bring all value to left side
- 2y - 3 = 0
factor
(y - 3)(y + 1)
solve for y
y = 3, y = -1
When plugged back into the equation, only y = 3 is true
<span>The dimension of the rectangle would be length=#4/sqrt3# and width =4-#4/3= 8/3#
Explanation:
Let one vertex on the x axis be x, then the other vertex would be -x. Length of the rectangle would be thus 2x and width would be #4-x^2#
Area of the rectangle would be A=#2x(4-x^2)= 8x-2x^3#
For maximum area #(dA)/dx=0=8-6x^2#, which gives x=#2/sqrt3#
The dimension of the rectangle would be length=#4/sqrt3# and width =4-#4/3= 8/3#
