Answer:
$95.38
Step-by-step explanation:
step 1
Find the area of one button
The area is equal to
we have
---> the radius is half the diameter
Convert to meters
assume
substitute
step 2
Find the area of 1,00 buttons
Multiply by 1,000
step 3
Find the cost
Multiply $15 per square meter by the total area of 1,000 buttons
Step-by-step explanation:
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
Answer:
434.9
Step-by-step explanation:
× π (4.7)²
434.893
The answer would be C. because you have to multiply all of the numbers and then divide by the 90 degree angle.
X² +18x = 0
To complete the square we are going to use formula a² +2ab +b² = (a+b)²
x² +2*9*x = 0
x² +2*9x+9² = 9²
(x+9)² = 9²
√(x+9)² = +/-√9²
x+9 = 9, or x+9 = -9
x=0, or x= - 18
The equation could be solved different way
x² +18x = 0
x(x+18) = 0
x=0 or x+18=0
x=0 or x=-18
