270÷60=4.5
Answer:
The polynomial will be
.
Step-by-step explanation:
The three degree polynomial function f(x) has zeros at x = 0 and at x = 4 having multiplicity 2.
Therefore, (x - 0) and (x - 4)² will be factors of the polynomial f(x).
Hence, the polynomial will be f(x) = Ax(x - 4)² .............. (1), where A is any constant that we have to evaluate.
Now, given that f(5) = 20
So, from the equation (1) we have
20 = A(5)(5 - 2)²
⇒ 
Therefore, the polynomial will be

Answer:
3. 
2. 
1. 
Step-by-step explanation:
3. Every 25 is worth 4, and since 3 by 4 is 12, 3⁄25 gets set to ",12", then attach the <em>whole number</em> [4] to it, giving you 4,12.
2. Every 15 is worth 6⅔, and since 7 by 6⅔ is 46⅔, moving the decimal mark twice to the <em>left</em> will give you the above answer, in <em>bar</em><em> </em><em>notation</em>, since it is a repeated decimal.
1. Every 8 is worth 12½, and since 7 by 12½ is 87½ [87,5], moving the decimal mark twice to the <em>left</em><em> </em>will give you 0,875.

Answer:
1) 
2) 
3) 
Step-by-step explanation:
To write logs of the form
in their exponential form, you take the base b and put it to the power of x and then set that equal to a:
.
1. Here, b = 5, a = 25, and x = 2, so: 
2. In this problem, b = 5, x = 2, and a = x, so: 
3. Finally, here, b = b, a = 64, and x = 3, so:
