Answer:
Step-by-step explanation:
Given that:
At point (5,3)
To find an equation of the tangent to the curve at the given point,
By without eliminating the parameter
t² + 5 = 4
t² = 4 - 5
t² = - 1
Then;
The equation of the tangent is:
y - 3 = -2x +10
y = -2x + 7
y = 2x - 7
By eliminating the parameter
x = 5 + In(t)
In(t) = 5 - x
The equation of the tangent is:
y - 3 = -2x +10
y = -2x + 7
y = 2x - 7
Answer:
21 is A and 23 is D
Step-by-step explanation:
Answer:
Number of extra boxes= 120
Step-by-step explanation:
Giving the following information:
Batteries per box= 50
Number of batteries= 18,000
Number of batteries in ecxess= 6,000
<u>We need to calculate the number of boxes required to cover the 6,000 extra batteries:</u>
Number of extra boxes= number of batteries / batteries per box
Number of extra boxes= 6,000 / 50
Number of extra boxes= 120
Answer:
V= 904.896cm^3
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of a cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
h - 18cm
d - 8cm
d = 2 * radius
r = d/2
r = 8/2
r = 4cm
π - 3.142
Insert the values into the formula of volume of a cylinder
V = πr^2h
V = 3.142 * 4^2 * 18
= 3.142 * 16 * 18
= 904.896cm^3
