Find a so that the point (-1, 2) is on the graph of f(x)=ax^2+5.
Gnesinka [82]
We are asked to determine the value of a such that the function f(x) = ax^2 + 5 is fit for the point given (-1,2). In this case, we substitute 2 to y and -1 to x. The result is then 2 = a*(-1)^2 + 5 ; 2 = a + 5; a is then equal to -3

Evaluate the function f (x)  4 • 7x for x  1 and x = 2. Show your work
SashulF [63]
The function and the first value stated for x are confusing.

Doing some research, I found that the problem is to evaluate the function   f(x)=4.7^x    for x = - 1 and x  2.

The solution is:

1) For x = - 1

f(-1)=4. 7^{-1} =4. (1/7)=4/7

2) For x = 2

f(2)=4.7^2=4(49)=196

Find the length of the arc of the circular helix with vector equation r(t) = 2 cos t i + 2 sin t j + tk from the point (2, 0, 0)
USPshnik [31]

\vec r(t)=2\cos t\,\vec\imath+2\sin t\,\vec\jmath+t\,\vec k

\implies\vec r'(t)=-2\sin t\,\vec\imath+2\cos t\,\vec\jmath+\vec k

\implies\|\vec r'(t)\|=\sqrt{(-2\sin t)^2+(2\cos t)^2+1^2}=\sqrt5

Then the length of the arc is

\displaystyle\int_0^{2\pi}\|\vec r'(t)\|\,\mathrm dt=\sqrt5\int_0^{2\pi}\mathrm dt=2\sqrt5\,\pi
