Answer:

5P3*6C4=60*15=900

Step-by-step explanation:

5P3 refers to the permutations of 5 items taken 3 at a time. To evaluate this, we use factorials as follows;

5P3=\frac{5!}{(5-3)!}

The factorial of an integer n is evaluated as;

n!=n*(n-1)*(n-2)*(n-3).......3*2*1

Using this concept, the above expression can now be simplified as follows;

5P3=\frac{5!}{2!}=\frac{5*4*3*2!}{2!}=5*4*3=60

Therefore, the permutations of 5 items taken 3 at a time is 60.

The next expression, 6C4 refers to the combinations of 6 items taken 4 at a time. The simplification utilizes similar concepts of permutations since we shall be involving factorials;

6C4=\frac{6!}{4!(6-4)!}=\frac{6!}{4!*2!}=\frac{6*5*4!}{4!*2*1}=\frac{6*5}{2*1}=15

Therefore, the combinations of 6 items taken 4 at a time is 15.

The final step is to evaluate the product;

5P3*6C4=60*15=900

EastWind [94]

Answer:

See below and attachment

Step-by-step explanation:

<u>Given function:</u>

  • y = -2(x - 3)² + 4

<em>The graph is attached and the axis of symmetry and all the required points plotted </em>

a) Axis of symmetry:

  • x = 3

b) It has no minimum as the leading coefficient is negative.

  • Maximum value is at vertex- the point (3, 4).
  • Maximum value is y = 4

c) and d) x - and y - intercepts already given in the question

e) Domain is all real numbers. x = ( -∞, +∞ )

Range is y = ( - ∞, 4]
