. y=-3x2 + bx + c; (1, 0) <br> find the unknown coefficients

aleksley [76]

Answer:

$y = - 3 {x}^{2} + bx + c \\ when \: (1,0) \\ 0 = - 3( {1})^{2} + b(1) + c \\ 0 = - 3 + b + c \\ b + c = 3 - - - (.) \\ at \: (0,0) \\ 0 = c \\ c = 0 \\ hence \: b = 3$

Find T, N, and B for the curve at the indicated point. [HINT: After finding T', plug in the specific value for t before computin

lyudmila [28]

Answer:

Step-by-step explanation:

Given that

$r(t) = (t,t,e^t)$

To find tangent, normal and binormal vectors at (0,0,1)

i) Tangent vector

$r'(t) = (1,1,e^t)\\$

At the particular point, r'(t) = (1,1,e)

Tangent vector = $\frac{r'(t)}{||r'(t)||} \\=\frac{(1,1,e)}{\sqrt{1+1+e^2} } \\=\frac{(1,1,e)}{\sqrt{2+e^2} }$

ii) Normal vector

T'(t) = $(0,0,e^t)\\$

At that point T'(t) = (0,0,e)/e = (0,0,1)

iii) Binormal

B(t) = TX N

= $\left[\begin{array}{ccc}i&j&k\\1&1&e^t\\0&0&e^t\end{array}\right] \\= e^t(i-j)$

Evaluate 11 C4 and 1 P4

Svet_ta [14]

Answer:

Step-by-step explanation:

11C4 = 11! / (7!*4!) = 11 * 10 * 9 * 8 * 7!/ 7! * 4!

11C4 = 11*10 * 9 * 8 / 24

11C4 = 11*10 * 3

11C4 = 330

========

You can't do the second one. Permutations and Combinations always give an answer greater than 1 and integers.
