2100 + 809 equals to 2909.
Expression: f(x) = [x - 4] / [x^2 + 13x + 36].
The vertical asympotes is f(a) when the denominator of f(x) is zero and at least one side limit when you approach to a is infinite or negative infinite.
The we have to factor the polynomial in the denominator to identify the roots and the limit of the function when x approachs to the roots.
x^2 + 13x + 36 = (x + 9)(x +4) => roots are x = -9 and x = -4
Now you can write the expresion as: f(x) = [x - 4] / [ (x +4)(x+9) ]
Find the limits when x approachs to each root.
Limit of f(x) when x approachs to - 4 by the right is negative infinite and limit when x approach - 4 by the left is infinite, then x = - 4 is a vertical asymptote.
Limit of f(x) when x approachs to - 9 by the left is negative infinite and limit when x approach - 9 by the right is infinite, then x = - 9 is a vertical asymptote.
Answer: x = -9 and x = -4 are the two asymptotes.
Answer:
939
Step-by-step explanation:
4695 divided by 5 =939
Answer:
A = 16π cm²
Step-by-step explanation:
We require to find the radius r
Given circumference C = 8π , then
2πr = 8π ( divide both sides by 2π )
r = 4 , then
A = πr² = π × 4² = 16π cm²
The area of your rectangle will vary depending on the dimensions. The area of any rectangle can be found with a simple equation...
Area = Length x Width or A = l x w
The answer to the area question will ALWAYS be in square units because when you multiply, you also multiply the units so, for example 2 inches x 2 inches = 4 inches^2.
Let's take a look at an example... You have a rectangle with a length of 8 feet and a width of 4 feet. What's the area?
Well... Area = Length x Width, so
Area = 8 ft x 4 ft
Area = 32 ft^2
Easy as that!
