Let a line in three dimensions be specified by two points and lying on it, so a vector along the line is given by

(1)The squared distance between a point on the line with parameter and a point is therefore(2)

To minimize the distance, set and solve for to obtain

(3)

where denotes the dot product. The minimum distance can then be found by plugging back into (2) to obtain

(4)(5)

Answer:

a) The minimum y-value of f(x) is -3

d) The minimum y-value of g(x) is -3

Step-by-step explanation:

Given in the question that,

f(x) = 3 $^{x}$ -3

g(x) = 7x² - 3

At large negative exponents, the value approaches to zero

y = $3^{-100}-3=-3$

y = $3^{-1000}-3=-3$

y = $3^{-10000}-3=-3$

Minimum y-value of g(x) will be when x = 0

y = 7x² - 3

y = 7(0) - 3

y = -3

Anastasy [175]

Hey!!!

here's your answer

X+128=180( sum of angle in straight line)

or,X=180-128

X=52 degree.

So the value of X is 52 degree.

Hope it helps...

Good luck on your assignment

Answer: 31) d 32) c

Step-by-step explanation:

31)

A = {1, 3, 5, 15}

B = {2, 3, 5, 7}

A ∪ B = {1, 2, 3, 5, 7, 15}

C = {2, 4, 6, 8}

(A ∪ B) ∩ C = {1, 2, 3, 5, 7, 15} ∩ {2, 4, 6, 8} = {2}

2 is the only number in both sets

32)

The pattern is: reflection, add symbol, ..., reflection, add symbol.

The last image shown is: add symbol

So the next image will be: reflection (flipped to the left)
