Answer:
(12 × 4) = 24 square feet
Step-by-step explanation:
The shaded triangle's area is found using the formula for the area of any triangle, A = 1/2 b*h. The base of the triangle is the longest side 12 ft. The height is 4 ft.
A = 1/2 *12*4 = 6*4 = 24 square feet
This is the solution though the expression is missing the 1/2.
(12 × 4) = 24 square feet
If the equation is x/(x^2-4) then I will solve it here
it's rational
therefor we can't have any impossibles like dividing by zero and square root of -1 an d stuff
f(x)=x/(x^2-4)
we know that the denomenator cannot be equal to zero so the numbers you cannot user are the numbers that will make the bottom number zero
so x^2-4=0
x^2=4
x=-2 or 2
so x cannot be -2 or 2, but it can be all other numbers so
domain=all numbers except -2 and 2
Answer:
2820.36 feet
Step-by-step explanation:
First we need to find the length of the outer corridor, and we do that by finding the length of the circunference with a radius of 25 feet:
C = 2 * pi * r = 2 * pi * 25 = 157.08 feet
Now, as Heather walks the outer corridor 17 times and the length of 6 spoke aisles (the radius of the circunference), we have that the total distance she walks is:
Distance = 17 * 157.08 + 6 * 25 = 2820.36 feet
A=22, 12
Solve for a by simplifying both sides of the equation, then isolating the variable.
