6 0

Complete the square
isolate x terms
y=(x^2-14x)+53
take 1/2 of -14 and square it ((-7)^2=49
add plus and minus of that inside the parntehasees

y=(x^2-14x+49-49)+53
factor perfect suqrae
y=((x-7)^2-49)+53
get rid of parnthasees
y=(x-7)^2-49+53
y=(x-7)^2+4

Refer to attached

34.

h(x) = 8 ⇒
x = 4 as per diagram

35.

g(8) = 4 as per table

36.

f(x) = 2 ⇒
x = -0.8 as per graph (approx.)

37.

f(2) = -2 as per graph

38.

h(-1) = -8 as per diagram

39.

g(x) = 4 ⇒
x = 9 or x = 8 as per table

There are 6 people in a raffle drawing, Two raffle winners each win gift cards,

Tju [1.3M]

Answer:

B. Combination: Number of ways = 15

Step-by-step explanation:

2 winners are to be chosen out of 6 people participating in the raffle drawing. In this case the order of selection does not matter, therefore, this situation involves combinations

So, we have to find combinations of 6 people taken 2 at a time. This can be represented by 6C2. The general formula for combinations is:

$^{n}C_{r}=\frac{n!}{r!(n-r)!}$

In this case n = 6 and r = 2. Using these values, we get:

$^{6}C_{2}=\frac{6!}{2! \times (6-2)!} \\\\ ^{6}C_{2}= \frac{6!}{2! \times 4!}\\\\ ^{6}C_{2}=\frac{6 \times 5 \times 4!}{2 \times 4!}\\\\ ^{6}C_{2}= \frac{30}{2}\\\\ ^{6}C_{2}= 15$

Thus, there are 15 ways to chose the winners. So, option B gives the correct answer.
