Answer:
(-9, 10)
Step-by-step explanation:
The location of the midpoint of a line with endpoint at (
) and (
) is given as (x, y). The location of x and y are:
Given the endpoint (9,8) and Midpoint (0,9), the location of the other endpoint can be gotten from:
Hence the endpoint is at (x2, y2) which is at (-9, 10)
The point-slope form of the equation for a line can be written as
... y = m(x -h) +k . . . . . . . for a line with slope m through point (h, k)
Your function gives
... f'(h) = m
... f(h) = k
a) The tangent line is then
... y = 5(x -2) +3
b) The normal line will have a slope that is the negative reciprocal of that of the tangent line.
... y = (-1/5)(x -2) +3
_____
You asked for "an equation." That's what is provided above. Each can be rearranged to whatever form you like.
In standard form, the tangent line's equation is 5x -y = 7. The normal line's equation is x +5y = 17.
<h2>First Question:</h2><h3>Given: </h3>
2 km = 1 cm
<h3>To Find:</h3>
The length of the road of 15 km.
<h3>Solution:</h3>
2 km = 1 cm
1 km = 1/2 = 0.5 cm
15 km = 0.5 × 15 = 7.5
<h2>Answer: </h2>
The length of the road is <u>7.5 cm</u>.
Therefore, <u>Option D. 7.5 cm</u> is correct.
