Answer:

m = 3/2

b = 0

y = 3/2x

Step-by-step explanation:

M is the slope, which is the rise/run of a line.

Using this, we know m is 3/2.

B is the y-intercept, which is where the line crosses the y-axis. In this case, B equals 0.

We use this information to put together our final equation of y= 3/2x (since B equals 0, there is no + or - after the slope)

Chris buys p pairs of parts and 4 more shirts than pairs of pants.Shirts cost $18 each and pair of pants cost $25 each.What does

Flauer [41]

The entire expression represents the total cost of the pants and shirts that Chris bought.

25p + 18(p + 4) ....let me break this down for u...

p = number of pants bought
25p is telling us the pants cost $ 25 a piece
p + 4 is telling us the number of shirts bought...4 more shirts then pants
18(p + 4) is telling us that each shirt bought costs $ 18

Maria took a taxicab from her home to the theater

Artist 52 [7]

Answer:

The answer is the third option, C = 5 + 0.25m

Step-by-step explanation:

We already know that the official price for the taxi is 5 dollars, so we aren't multiplying that value by anything.

However, the text mentions that for each mile, Maria is taxed an extra .25 cents. Therefore, you have to add the base amount, 5, plus the 25cent with the m next to it to symbolize that however many miles she goes, the 25 cents will be multiplied by that value.

The diameter of a circleis 170inches. The circle has two chords of length 26 inches. What is the distance from each chord to the

vivado [14]

Answer:

Hence the Distance from each other chord to center is 84 inches.

Step-by-step explanation:

Given:

Diameter =170 inches

2 chords with each length =26 inches.

To Find:

Distance of each chord from the circle.

Solution:

Consider a circle with center as O ,

And OA as Radius

(Refer the attachment)

So as chord be BC and DE respectively with each of 26 length

They have both same length so they should located at same distance from center but as mirror images of each other opposite side of the diameter as shown in fig.

Hence we can calculate for one chord as follows:

Radius =diameter/2=170/2=85

r=85 inches.

Let distance from center t o chord be 'x'

Now draw perpendicular to chord BC with F as midpoint for chord and join endpoints of chord to the center which forms triangle OFC as right angled triangle,

By using pythagorus Theorem

$OC^2=FC^2+OF^2$

Here OC=85 inches , FC=26/2=13 inches.

$85^2=13^2+OF^2$

$OF^2=85^2 -13^2$

$OF^2=7225-169$

$OF^2=$ 7056

$OF=84$ inches

Hence the Distance from each other chord to center is 84 inches.

15.

boyakko [2]

Explanation:

${3 \choose 2} = \frac{3!}{2!(3-2)!} = \frac{6}{2*1} = 3$

${3 \choose 1} = \frac{3!}{1!(3-1)!} = \frac{6}{1*2} = 3$

b) First, we have that

${n \choose k} = \frac{n!}{k!(n-k)!}$

On the other hand,

${n \choose n-k} = \frac{n!}{(n-k)!(n(n-k))!} = \frac{n!}{(n-k)!k!}$

Therefore, both expressions are equal. This makes sense, because selecting k elements from a group of n is the same than specify which elements you will not select. In order to specify those elements you need to select the n-k elements that will not be selected. Hence, each time you are selecting k from n, you are also selecting n-k from n, and from that reason both combinatorial numbers are equal.
