The distance between two points with the given coordinates in space is;

Distance = 17 units

We are given the coordinates;

(32, 12, 5)

(20, 3, 13)

d = √((x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²)

From the equation given to us, we can see that;

x₁ = 32

x₂ = 20

y₁ = 12

y₂ = 3

z₁ = 5

z₂ = 13

d = √((20 - 32)² + (3 - 12)² + (13 - 5)²)

d = √(144 + 81 + 64)

d = √289

d = 17

Thus, the distance between the two points is 17 units

Answer:

140% is 140/100 = 7/5 is fraction

Answer:

The answer is 5

Step-by-step explanation:

Since we already know what x we can just substitute it.

5(8)-2y=30

5 times 8 is 40

40-2y=30

Subtract 40 on both sides:

-2y=-10

Divide -2 on both sides:

y=5

Answer:

g=11

Step-by-step explanation:

What I did was Isolate the variable by dividing each side by factors that don't contain the variable.

Set the equation equal to zero and factor the left side.

intercept is (0,7)

use formula y=mx+b to plug in numbers

(slope is m and y intercept is b)

y=mx+b

y=2x+7

Answer:

(1-sin(x))/(1+cos(x)) = (csc(x) - 1)(csc(x) - cot(x))

Step-by-step explanation:

(1 - sin(x)) / (1+cos(x)) =

[ (1-sin(x))/ (1+cos(x)) ] * (1-cos(x))/(1-cos(x)) =

(1-sin(x))(1-cos(x)) / (1 - cos^2(x)) =  

(1-sin(x))(1-cos(x)) / (sin^2(x)) =

[ (1-sin(x)) / sin(x) ] * [ (1 - cos(x)) / sin(x) ] =

(csc(x) - 1)(csc(x) - cot(x))

Step-by-step explanation:

Answer: 15

Step-by-step explanation:

you would have to find the square root of 225 and this is 15 so if you do 15x15 you will get 225

and if you need to find the perimeter you add up all the sides

15x4=60

The perimeter of a square is 60

Answer:

[tex]15.2~mph[/tex]

Step-by-step explanation:

Let the time flown by the flying carpet be [tex]t[/tex]. Then, we have that [tex](2.4)/t=(1.4)/t+2*4[/tex].

We multiply both sides of the equation by [tex]t[/tex] to get [tex]2.4=1.4+8t[/tex].

We subtract [tex]1.4[/tex] from both sides to get [tex]1=8t[/tex].

We divide both sides of the equation by [tex]t=1/8[/tex].

We know that the speed of the flying carpet in still wind is the average of the rates of the speed of the flying carpet with the wind and against the wind.

The speed with wind is [tex](2.4)/(1/8)=19.2[/tex]mph.

The speed against wind is [tex](1.4)/(1/8)=11.2[/tex]mph.

The speed in still wind is [tex](19.2+11.2)/2=(30.4)/2=15.2[/tex].

Therefore, the answer is [tex]\boxed{15.2~mph}[/tex] and we're done!

The speed of the flying carpet in still air is 15.2 mph

Let x represent the speed of the flying carpet in still air, and t represent the time.

Speed = distance/time

Since the wind speed is 4 mph, hence:

When flying with the wind:

x + 4 mph = 2.4/t     (1)

When flying against the wind:

x - 4 mph = 1.4/t     (2)

Dividing equation 1 by 2 gives:

(x + 4) / (x - 4) = 2.4/1.4

1.4x + 5.6 = 2.4x - 9.6

x = 15.2 mph

The speed of the flying carpet in still air is 15.2 mph

Answer:

-1

Step-by-step explanation:

F(x - 1) = 2x + 3.

 Rewrite the right side (2x + 3)

F(x - 1) = 2[ x ] + 3

F(x - 1) = 2[ x - 1 + 1 ] + 3  =  2 [ (x - 1) + 1 ]   + 3

=  2 (x - 1) + 2 + 3

=  2(x - 1) + 5

replace "x - 1" with "-3" :

F(-3)   =     2(-3) + 5  =  -1
