point Find the length of segment CD with C(2,3) and D (-3, 15​

Answers

Step-by-step explanation:

so, if the text is correct, the 2 points are

(2, 3) and (-3, 15).

the length of the line segment is the distance between both points.

did this we use Pythagoras for right-angled triangles.

c² = a² + b²

c is the Hypotenuse and the distance between both points. a and b are the legs (enclosing the 90 degree angle), which are simply the differences of the x and the y coordinates.

so,

distance² = (2 - -3)² + (3 - 15)² = 5² + (-12)² = 25 + 144 = 169

distance = sqrt(169) = 13 = length of line segment

Two positive numbers have a difference of 8. The larger number is two more than twice the smaller. Find the two numbers

Answers

Answer:   6 & 14

Step-by-step explanation:

Let the bigger number be 'p' and the smaller number 'p'.

Since the numbers have a difference of 8, then  p - q = 8

& since the larger number is two more than twice the smaller, then

                                                                                                        p = 2q + 2

⇒   (2q + 2) - q = 8                       [by substituting for equation for p]

                     q = 6

Since q = 6,

⇒  p - 6 = 8

          p = 14

∴ the smaller number is 6 and the bigger 14

Show that the equation x^3 + 6x - 5 = 0 has a solution between x = 0 and x=1

Answers

Answer:

Step-by-step explanation:

Solve the equation for 0 and 1:

x^3 + 6x -5

Replace x with 0:

0^3 + 6(0) -5 = -5

Replace x with 1:

1^3 + 6(1) -5 = 1+6 -5 = 2

Because the value of f(0) is negative and the value of f(1) is positive then there is at least one value of x between 0 and 1 that f(x) = 0

This is equal to 12, meaning x = 24.

First we will simplify both equations....#1

#2

How?

When the number is in negative the smaller number is greater than the greater number.

Answer:

2nd answer, and 5 hours

Step-by-step explanation:

Section 1

The answer is the 2nd one down.  The tickets are selling at a rate of

floor tickets: 100/h; stand tickets:  75/h

Since the stand tickets were selling 150 in 2 hours, only 75 were sold per hour.

Section 2

There are only 375 stand tickets left to sell.

Every 2 hours 150 are sold or you can also say 75 per hour.

If you're selling 75 per hour, you would divide 375 by 75 which would give you 5 hours to sell out the stands tickets.

375/75 = 5 hours
