Answer for A: a = -x4 + px - 2 x 2 - b + 3x x 3
Answer for B: b = -ax3 - x4 + px - 2x2 + 3x
Answer: 49
to find g^-1 switch the x and y and solve for y
y = 1/7x - 1
x = 1/7y - 1
x + 1 = 1/7y
7(x+1) = y
g^-1 = 7(x+1)
g^-1 (6) = 7(6+1) = 7(7) = 49

Answer:
The approximate area of the circle is <u>2462 centimeters²</u>.
Step-by-step explanation:
Given:
John and Becky measured the circle-shaped part of a sun they drew on the sidewalk. The diameter of the circle is 56 centimeters.
Now, to get the area of the circle approximately.
Diameter of the circle = 56 centimeters.
<em>So, the radius </em><em>(r)</em><em> of the circle</em> =
Using 3.14 for π.
Now, to get the area of circle by putting formula:
<u><em>Approximately the area of the circle = 2462 centimeters².</em></u>
Therefore, the approximate area of the circle is 2462 centimeters².
Answer:
Step-by-step explanation:
Radius r = 15
Circumference = 2πr = 30π cm
Circumference of cone = arc length of sector
= 30π × 216°/360°
= 18π cm
Radius of base of cone = 18π/(2π) = 9 cm
Slant height of cone = radius of circle = 15 cm
Height of cone = √(15² - 9²) = 12 cm
