Given that P = (2, 9) and Q = (4, 14), find the component form and magnitude of vector PQ.

1 answer:

6 0

We are asked to determine the lengths of the line segment drawn with these points as endpoints. The equation of the distance between points is,
d = sqrt ((y2 - y1)² + (x2 - x1)²)
Substituting the coordinates of the points,
d = sqrt ((14 - 9)² + (4 - 2)²)
The numerical value for d is approximately 5.39.

Answer:

$9*10^{11}$

Step-by-step explanation:

we have

$(3*10^{6})*(3*10^{5})$

we know that

$(a*10^{b})*(a*10^{c})=(a*a)*10^{(b+c)}$ -----> the bases are multiplied and the exponents are added up

in this problem

$(3*10^{6})*(3*10^{5})=(3*3)*10^{(6+5)}$

$=9*10^{11}$

The is answer is definitely D, because he computed the total population of 3,320 in the survey of his targeted people that he specified which was grade school and high school. In order for his computation to work for his market analysis he used the radius of 5m and the 75% he wanted to achieve.

Find the value of X A: 2 B: 4 C: 6 D: 8

11111nata11111 [884]

Using the Pythagorean theorem:

x^2 + (x-2)^2 = (√20)^2

Simplify the right side:

x^2 + (x-2)^2 = 20

Subtract 20 from both sides:

x^2 + (x-2)^2 - 20 = 0

Factor:

(x-4)(x+2) = 0

Solve for each x:

x = 4 and x = -2

The side cant be a negative value, so the answer would be x = 4

The answer is B.
