How do i find the shorted distance between the point and the line

Mathematics
1 answer:
m_a_m_a [10]2 years ago
3 0

Answer:

5 units

Step-by-step explanation:

3x + 4y = 8

4y = -3x+8

y = -3/4+2

The shortest distance between a point and a line is the perpendicular line.

Slope of the perpendicular line: 4/3 and point (-3,-2)

b = -2-(4/3)(-3) = 2

Equation of the perpendicular line: y=4/3x+2

y is equal y

4/3x+2= -3/4x+2

4/3x +3/4x = 2-2

x = 0

Plug x=0 into one of the equations to find y

y = 4/3(0) + 2

y = 2

(0,2) and (-3,-2)

Distance = sqrt [(-3-0)^2 + (-2-2)^2]

Sqrt (-3)^2+ (-4)^2

Sqrt 25 = 5

qaws [65]

Answer:

D. The population of California was approximately two times the population of Florida.

Step-by-step explanation:

California's population was 4 x 10^7= 40,000,000

Florida's population was 2 x 10^7= 20,000,000

So therefore Califirnia's population was approximately two times the population of Florida.

olga_2 [115]

Answer: 33.3%

Step-by-step explanation:

First find the difference between the players in try-outs over the years.

= 90 - 75

= 25

Then use this difference to find the percent increase:

= Difference / Players last years * 100%

= 25 / 75 * 100%

= 33.3%

For what values of the numbers a and b does the function below have maximum value f(1) = 4? (Round the answers to three decimal
Georgia [21]
F (x) = a x  e^{b x^{2} }
f ` (x) = a( e^{b x^{2} } +x e ^{b x^{2} } *2 b x )=a e ^{b x^{2} } (1+2b x^{2} )
f ( 1 ) = 4
f ` ( 1 ) = 0
4 = a e ^{b}  \\ a e ^{b} (1 + 2 b ) = 0 \\ 4 ( 1 + 2 b )= 0

b = -1/2
4=a e ^{-1/2} =  \frac{a}{ \sqrt{e} }  \\ a = 4 \sqrt{e}
Answer:  a = 4√e, b = -1/2
