Y - y1 = m(x - x1)
slope(m) = 3
(4,7)....x1 = 4 and y1 = 7
now we sub
y - 7 = 3(x - 4) <==
Part A:
The circumference of the circle is 197.92.
Explanation:
The formula for circumference of a circle is C=2 πr. If you insert the numbers, it would be C=2 x 3.14 x 31.5. Hence, the answer is 197.92.
Part B:
The area is 3117.25 square cm.
Explanation:
The formula for area of a circle is A= πr ². Inserting the numbers, it is A=3.14 x 31.5 ². Therefore the answer is 3117.25 cm ².
14 and 22 are the two numbers in question
Answer:
Step-by-step explanation:
Let the expression representing a situation is,
y = 6a + 2(c - b)
Where, a, b and c are the constants
If a = 2, b = 1 and c = 9
By substituting these values in the expression,
y = 6(2) + 2(9 - 1)
y = 12 + 16
y = 28
Therefore, for all given values of the constants value of y is 28.
The first thing you have to take into account is the definition of the axis in the complex plane.
We have then:
The vertical axis represents the imaginary part.
The horizontal axis represents the real part.
We then have the following number:
-14 - 5i
Since the real part and the imaginary part are negative, then the number is located in the third quadrant of the complex plane.
Answer:
Quadrant III.
