How many different arrangements can be made using all the letters in the word topic

Mathematics

Goryan [66]3 years ago

The formula to find the permutations is nPr = \frac{n!}{(n-r)!}

Here n represents the total number of objects

r represents the number of objects taken at a time

The word TOPIC has 5 letters.

All the five letters are different.

And we need to take all 5 letters.

Hence n = 5 & r = 5

Number of arrangements = 5P5 = \frac{5!}{(5-5)!} =\frac{5!}{0!}  = 5!=120

120 different arrangements can be made using all the letters in the word TOPIC

Whats -2(4k-7)=22-8k in Algebra
Andrei [34K]

Let's solve your equation step-by-step.

−2(4k−7)=22−8k

Step 1: Simplify both sides of the equation.

−2(4k−7)=22−8k

(−2)(4k)+(−2)(−7)=22+−8k(Distribute)

−8k+14=22+−8k

−8k+14=−8k+22

Step 2: Add 8k to both sides.

−8k+14+8k=−8k+22+8k

14=22

Step 3: Subtract 14 from both sides.

14−14=22−14

0=8

So, the answer is 0=8.

What is the value of x?
Inessa [10]

Answer:

Step-by-step explanation:

There are 180 degrees in a triangle. With that information we can make the equation: 180=(47+85)+x.

When you solve it becomes:

180=132+x --> x=48 degrees

Hope that helped!

Write the equation in standard form for the circle that has a diameter with endpoints (22,0) and (2,0)
vovikov84 [41]

Answer:

(x - 12)² + y² = 100

Step-by-step explanation:

The standard form of the equation of a circle is;

(x - a)² + (y - b)² = r²

where:

a and b are the coordinates of the centre of the circle

r is the radius

We are given the coordinates of the endpoints of the diameter as; (22,0) and (2,0)

Thus, the centre of the circle would be at the mid point of the endpoints of the diameter.

Coordinates of the centre is;

((22 + 2)/2), (0 +0)/2))

This is;

(12, 0)

So, a = 12 and b = 0

Now,to get the radius r, we will use the formula;

r = √[(x2 - x1)² + (y2 - y1)²]

Where;

(x1, y1) and (x2, y2) are 2 points namely (12,0) and (22, 0)

r = √[(12 - 22)² + (0 - 0)²]

r = √(-10)²

r = √100

r = 10

Thus,equation of the circle is;

(x - 12)² + (y - 0)² = 10²

(x - 12)² + y² = 100
