By pythagoras theorem,
cb^2 = ac^2 + ab^2
5^2 = ac^2 + 3^2
ac^2 = 5^2 - 3^2 = 16
ac = squareroot 16 = 4cm
Answer:
table a
Step-by-step explanation:
To be a function, every x has to have exactly one y. In table b the x value 5 has an output of 2 and 6 and therefore, since it has more than one y it is not a function. In table D the x value 6 has a y output of 7 and 2. Therefore it is not a function. In table A every x has exactly one y.
Answer:
I think it is the first one
Answer:
(x - 4)
Step-by-step explanation:
Given
x² + 2x - 24
Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (+ 2)
The factors are + 6 and - 4, since
6 × - 4 = - 24 and 6 - 4 = + 2, thus
x² + 2x - 24 = (x + 6)(x - 4) ← in factored form
Thus the other factor is (x - 4)
