The domain of exponential function is equal the set of all real numbers.
Volume = area of triangular end * length
= 1/2 * 3 * 4 * 20
= 120 units^3 (answer).
Its B
Answer:
The surface area is about 408.47
Step-by-step explanation:
We must use Pythagorean Theorem in order to find the the height of the cone in order to use the surface area of a cone formula. The formula that you use would be A=πr(r+h2+r2). You already have the radius which is 5.
Pythagorean Theorem
You have two leg measurements of the triangle, one of which is the hypotenuse. The hypotenuse is 21.
- a^2 + (5)^2 = (21)^2
- a^2 +25 = 441
Subtract 25
Take the square root of 416 and you get about 20.4. So the height of the cone would be about 20.4.
πr(r+h2+r2) ----> π(5)(5+(20.4)2+(5)2) and you get about 408.47
Answer:
Step-by-step explanation:
Given
(0, 1, 0)
The vector equation is given as:
Substitute values for x, y and z
Differentiate:
The parametric value that corresponds to (0, 1, 0) is:
Substitute 0 for t in r'(t)
The tangent line passes through (0, 1, 0) and the tangent line is parallel to r'(0)
It should be noted that:
The equation of a line through position vector a and parallel to vector v is given as:
Such that:
and
The equation becomes:
By comparison:
and
The parametric equations for the tangent line are:
Answer:
B
Step-by-step explanation:
(x,y)
(0,2)
the 2 lands on the y so therefor 2 is the y-intercept
i hope this helps :)
