Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (5, -2)

Point (-8, -3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute [DF]: $d = \sqrt{(-8-5)^2+(-3+2)^2}$
Subtract/Add: $d = \sqrt{(-13)^2+(-1)^2}$
Exponents: $d = \sqrt{169+1}$
Add: $d = \sqrt{170}$

erastovalidia [21]

Answer: % increase ≈ 3433%

Step-by-step explanation:

Step 1: work out the difference (increase) between the tow numbers you are comparing.

Increase = New Number - Original Number

Step 2: Divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number x 100

Step 3: Plug in known values

Increase = 6.18

Original Number = 0.18

% increase = 6.18 ÷ 0.18 x 100

% increase = 34.333... x 100

% increase ≈ 3433%

A store Is having a sale where movies are 15% off their original price. a movien is on sale for $22.10 what was the orgial price

sergeinik [125]

X= original $

Original $ - % of original $= total $

x - 15%x= $22.10
x- 0.15= 22.10
Combine like terms
0.85x= 22.10
Divide both sides by 0.85
x= $26 original price

Hope this helps! :)

Can someone help me please

Anna [14]

Answer:

${x}^{4} = 2880$

Step-by-step explanation:

${y}^{2} = 20 \: (eq . \: 1)$

${x}^{2} = {(2 \sqrt{3y)} }^{2} = 12y$

Putting value of eq. 1 in the following:

${x}^{4 } = {(12y)}^{2} = 144{y}^{2} = 144 \times 20 = 2880$

krek1111 [17]

Answer:

Step-by-step explanation:

we are given some scenerios and we are to find out the total number of ways after mentioning permutations, combinations, or neither

a. How many ways can a coach choose two co-captains from 16 players in the basketball team?

Combination because both are having same position so order does not matter

16C2 = 120

b. In how many ways can seven questions out of ten be chosen on an examination?

Combinations because order of question does not matter.

10C7 = 10C3 = 120

c. Find the number of ways that 10 women in the finals of the skateboard street competition can finish first, second, and third in the X Games final.

Here order matters. Hence permutation

10P3 = 720

d. A postal zip code contains five digits. How many different zip codes can be made with the digits 0–9? Assume a digit can be repeated.

Here repitition is allowed. So neither permutation nor combination.

No of ways = $10^5$
