Number is no because there is more than 12 in. (Only 12in in a foot). And 2 is yes because half of 85 is 42.5 and there’s more room than that.

Answer:

1. 8/4+ 3= 5

2. 5/(10/2)= 1

3. 5+10/2=10

4. 8/2+5x5= 29

5. 5+3/15+2= 10.15

6. 30+6x11-11= 25.11

7. 12 + (19+2) / 3 =19

In another state, all license plates consist of 6 symbols chosen from the 26 letters of the alphabet and the digits 0-9. How man

Amiraneli [1.4K]

Answer:

11,232,000 license plates are possible.

Step-by-step explanation:

The order in which the symbols are chosen is important(ABC is a different plate than BAC), which means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this question:

3 letters from a set of 26.

3 digits from a set of 10. So

$T = P_{26,3}P_{10,3} = \frac{26!}{23!} \times \frac{10!}{7!} = 11232000$

11,232,000 license plates are possible.

Find the vertex of the given quadratic function.

ki77a [65]

given f(x) in factored form, equate to zero for x-intercepts

(x - 8)(x - 4) = 0, hence

x = 4, x = 8 ← x- intercepts

The vertex lies on the axis of symmetry which is situated at the midpoint of the x- intercepts

x- coordinate of vertex = $\frac{4+8}{2}$ = 6

f(6) = (6 - 8 )(6 - 4 ) = -2 × 2 = - 4 ← y-coordinate

vertex = (6, - 4 ) → B
