Answer:

8820 ways

Step-by-step explanation:

Given that :

Selecting 4 pairs of pant from 8 available and selecting 5 shirts from 9 available

Using combination :

4 pants from 8 = 8C4

5 shirts from 9 = 9C5

Recall:

nCr = n! / (n-r)! r!

8C4 * 9C5 = [8! /(8-4)!4!] * [9! /(9-5)!5!]

8C4 * 9C5 = (8! /4!4!) * (9! /4!5!)

8C4 * 9C5 = 70 * 126

8C4 * 9C5 = 8820 ways

Simplify the following expression 9v^2(v^2+3v-4)
Anvisha [2.4K]

The answer would be 9v ^4 + 27v ^3 - 36v^2

Step-by-step explanation:

You first would multiply each term in the parenthesis by 9v^2

9v^2 (v^2) + 9v^2 (3v) - 9v^2 (4)

After this you combine the like terms

9v^2 * v^2 is 9v^4

9v^2  * 3v is 27v^3

-9v^2 * 4 is -36v^2

Because you can not simplify it any smaller, this is your final answer

A Ferris wheel travels in a circular motion and measures 40 meters from the top car to the bottom car. What is the length of the
Romashka-Z-Leto [24]

Answer:

20 m

Step-by-step explanation:

the distance from the top car to the bottom car is equal to the diameter of the wheel. The diameter is 40 m, and that is twice the radius. The radius of the Ferris wheel is (40 m)/2 = 20 m.

Let G denote the centroid of triangle ABC. If triangle ABG is equilateral with side length 2, then determine the perimeter of tr
zhannawk [14.2K]
We know from Euclidean Geometry and the properties of a centroid that GC=2GM. Now GM=sin60*GA=\sqrt{3}. Hence CM=GC+GM=3*\sqrt{3} /. Now, since GM is normal to AB, we have by the pythagoeran theorem that:
AC^2=AM^2+GM^2=BM^2+GM^2=BC^2
Hence, we calculate from this that AC^2= 28, hence AC=2*\sqrt{7}=BC. Thus, the perimeter of the triangle is 2+4*\sqrt{7}.

Evaluate f(x)=e2x−1+2 when x=3. Give an approximate answer rounded to three decimal places.
olganol [36]

Answer:

f(3) ≈ 17.310

Step-by-step explanation:

e = 2.71828

Step 1: Define

f(x) = e2x - 1 + 2

x = 3

Step 2: Substitute and evaluate

f(3) = e2(3) - 1 + 2

f(3) = 6e + 1

f(3) = 16.3097 + 1

f(3) = 17.3097

f(3) ≈ 17.310
