You’re answer would be x=18.28
A recursive formula designates the starting term, a1, and the nth term of the sequence, an , as an expression containing the previous term (the term before it), an-1. ... Find a recursive formula. This example is an arithmetic sequence (the same number, 5, is added to each term to get to the next term).
Answer:
- Discontinuity at (-1,6)
- The zero is at (-7,0)
Step-by-step explanation:
Given the function , you need to factor the numerator. Find two number whose sum be 8 and whose product be 7. These are 1 and 7, then:
Then, the denominator is zero when
Therefore, does not belong to the Domain of the function. Then, (-1,6) is a discontinuity point.
Simplifying, you get:
You can observe that a linear function is obtained.
This function is equal to zero when , therefore the zero of the function is at (-7,0).
Answer: 4cm
Step-by-step explanation:
The area of a parallelogram is calculated by multiplying the height by the length:
Area = Height * length
Assume the length is x, substituting values would make the formula:
16 = 4 * x
4x = 16
x = 16/4
x = 4 cm
I think the ratio would be 5 : 2 : 2 : 3
