Answer:
a) OA = 1 unit
b) BC = 3 units
c) OD = 2 units
d) AC = 3√2 units
Step-by-step explanation:
Given function:
<h3><u>Part (a)</u></h3>
Point A is the x-intercept of the curve.
To find the <u>x-intercept</u> of the curve (when y = 0), set the function to zero and solve for x:
Therefore, A (1, 0) and so OA = 1 unit.
<h3><u>Part (b)</u></h3>
If OB = 2 units then B (-2, 0). Therefore, the x-value of Point C is x = -2.
To find the y-value of Point C, substitute x = -2 into the function:
Therefore, C (-2, -3) and so BC = 3 units.
<h3><u>Part (c)</u></h3>
<u>Asymptote</u>: a line that the curve gets infinitely close to, but never touches.
The y-value of Point D is the horizontal asymptote of the function.
The function is undefined when x = 0 and therefore when y = -2.
Therefore, D (0, -2) and so OD = 2 units.
<h3><u>Part (d)</u></h3>
From parts (a) and (c):
To find the length of AC, use the distance between two points formula:
Therefore:
For 15 you divide 6 by 12 which is two so she takes 2 quizzezs a week so 2 x 3 is 6 so the other three weeks she took 6 quizzes add 12 and 6 and you get 18 :)
Answer:
The volume of the sphere is 972π mm³
Step-by-step explanation:
To calculate the volume of a sphere we have to use the following formula:
V = volume
r = radius = 9mm
π = pi
V = ⁴⁄₃πr³
we replace with the known values
V = ⁴⁄₃ * π * (9mm)³
V = π * ⁴⁄₃ *729mm³
V = π * 972mm³
V = 972π mm³
The volume of the sphere is 972π mm³
