What is the slope of the tangent line through (3,2) and (x,y) for x=-2 and y=x3

1 answer:

3 0

First you must derive the equation to find the slope:
y = x ^ 3
y '= 3x ^ 2
Then, for x = -2 we have the slope is:
y '(- 2) = 3 (-2) ^ 2 = 12
Then the equation of the line with slope equal to 12 and passing through point (3,2) is:
y = 12 (x-3) +2

Please simplify n-2/n^2-4

Doss [256]

Answer:

$\frac{1}{ {n} + {2}}$

Step-by-step explanation:

$\frac{n - 2}{ {n}^{2} - 4} \\ \\ = \frac{n - 2}{ {n}^{2} - {2}^{2} } \\ \\ = \frac{n - 2}{ ({n} + {2})({n} - {2})} \\ \\ = \frac{1}{ {n} + {2}} \\$

Clara scored a 79 on her history test what grade does she have to get on her next test so she will have a average of a 83

Airida [17]

79 is 4 below 83 so her next grade needs to be 4 above in order to get an average of 83. The answer is 87.

The altitude drawn to the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 4 and 12. Find the leng

fomenos

The altitude will be the geometric mean of the lengths, so
$h=\sqrt{4 \cdot 12}=4\sqrt{3}$ . The smaller leg is the hypotenuse of a right triangle sides 4 and $4 \sqrt{3},$ so the usual trig cliche, hypotenuse 8.

Answer: 8
