Find the distance CD rounded to the nearest tenth

Mathematics
1 answer:
motikmotik2 years ago
3 0

Answer:

CD ≈ 15.0

Step-by-step explanation:

calculate CD using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = C (7, - 4) and (x₂, y₂ ) = D (- 8, - 5)

CD = \sqrt{(-8-7)^2+(-5-(-4))^2}

     = \sqrt{-15)^2+(-5+4)^2}

     = \sqrt{225+(-1)^2}

     = \sqrt{225+1}

     = \sqrt{226}

     ≈ 15.0 ( to the nearest tenth )

6x+4=4x-2 WILL GIVE BRAINLIEST 60 POINTS
vesna_86 [32]

Answer:

0.200

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    6*x-4-(-4*x-2)=0

Step by step solution :

STEP 1

1.1     Pull out like factors :

  10x - 2  =   2 • (5x - 1)

STEP 2

2.1      Solve :    2   =  0

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    5x-1 = 0

Add  1  to both sides of the equation :

                     5x = 1

Divide both sides of the equation by 5:

                    x = 1/5 = 0.200

solution:

x = 1/5 = 0.200

If every day I make 2 dollars and every time I reach 50 dollars it adds 25 cents to my daily income how many days will it take f
Vsevolod [243]

9514 1404 393

Answer:

  659

Step-by-step explanation:

We assume the daily rate increases at each multiple of $50. When the balance reaches $50 on day 25, the pay on day 26 is $2.25.

Similarly, when the balance reaches 9628.75 on day 658, the pay will be $50 on day 659.

I found this easiest to solve using a computer program. A spreadsheet can do it by computing the number of days between raises. This is shown in the attachment.
