Use function notation to represent the area of a circle whose circumference is 103 cm

Mathematics
1 answer:
Nataly_w [17]3 years ago
4 0

Circumference of the circle =103 cm

i.e., C = 2 \pi r = 103

i.e., r = \frac{103}{2 \pi}


Area of the circle is given by

A = \pi r^2

A = \pi (\frac{103}{2 \pi})^2

A = \pi (\frac{10609}{4 \pi^2})

A =\frac{10609}{4 \pi}

Therefore, the area of the circle is: A =\frac{10609}{4 \pi}  cm^2

Factor the expression 49b²-36​
Travka [436]

Answer:

49b² - 36

Step-by-step explanation:

Find the factors of 49 & 36:

49 = 1, 7, 49

36 = 1, 2, 6, 18, 36

As you can tell, there are no common factors (1 does not count), therefore, the expression given is already in most factored form.

49b² - 36 is your answer.

How do I describe the real zeroes of this function using Descartes's Rule of Signs?
Serhud [2]
The number of positive roots is the number of changes of signs there are, then decrease by 2 each time and stop when you get to 1 or 0

negative roots, sub every x with -x and reevaluate, count change of signs
decrease by 2 each time and stop when you get to 1 or 0

y=+2x⁵-x⁴-2x³+4x²+x-2
+,-,-,+,+,-
 1    2  3

3 or 1 positive roots

replace x with -x ( baically flip all signs of odd powerd numbers)

y=-2x⁵-x⁴+2x³+4x²-x-2
   -,-,+,+,-,-
     1    2

2 or 0 negative roots



3 or 1 positive roots
2 or 0 negative roots
