A cheerleading squad consists of ten cheerleaders of ten different heights. How many ways are there for the cheerleaders to line

Sindrei [870]

Answer:

11340

Step-by-step explanation:

We have 10 cheerleaders of ten different heights. There are two rows each having 5 positions so that five cheerleaders occupy the first row that have height less than the five cheerleaders who occupied the second row.

Therefore, Out of ten cheerleaders, two cheerleaders will be selected out of which the tallest one will occupy the position in the upper row and the second one will occupy in the lower row, therefore these two positions will be occupied in $10C_{2}$ ways. Now, we are left with 8 cheerleaders and following the same path, the next two positions will also be occupied in $8C_{2}$ ways, similarly, following the same path, the number of ways the cheerleaders will occupy the position will be: $10C_{2}$ × $8C_{2}$ × $6C_{2}$ × $4C_{2}$ × $2C_{2}$

Which function represents a reflection of f(x) = Three-sevenths(2)x over the x-axis?

uranmaximum [27]

<u>Given:</u>

The given function is $f(x)=\frac{3}{7}(2)^{x}$

We need to determine the reflection of f(x) over the x - axis

<u>Reflection over x - axis:</u>

The translation rule to reflect over the x - axis is given by

$(x, y) \rightarrow(x,-y)$

Thus, applying the rule, the function becomes

$-y=\frac{3}{7}(2)^{x}$

Multiplying both sides of the equation by -1, we have;

$y=-\frac{3}{7}(2)^{x}$

This can be written as

$g(x)=-\frac{3}{7}(2)^{x}$

Hence, the reflection of the function over the x - axis is $g(x)=-\frac{3}{7}(2)^{x}$

Thus, Option A is the correct answer.

solve 3x+2y=16 and y=x+3 using substitution. Find the ordered pair. Please show all the steps taken to find the answer.

Nat2105 [25]

Answer:

(2,5)

or x=2, y=5

Step-by-step explanation:

3x+2y=16

substitute y =x+3 every place you see a y

3x + 2(x+3) = 16

distribute

3x + 2x +6 = 16

combine like terms

5x+6 = 16

subtract 6 from each side

5x+6 -6 =16-6

5x =10

divide by 5

5x/5 = 10/5

x = 2

now we need to find y

y = x+3

y = 2+3

y=5

(2,5)

or x=2, y=5
