After reflection, the x-coordinates remains unchanged while the y-coordinates are negated.

<h3>Reflection of coordinates over the xy axis</h3>

The translation rule for reflecting the coordinate (x, y) over the x-axis is expressed as:

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

Given the following coordinates of the vertices from the figure J(-7, 7), K(-5, -2) and L(-2, 3)

If the coordinates ara reflected over the x-axis, the resulting coordinates will be J(-7, -7), K(-5, 2), and L(-2, -3).

After reflection, the x-coordinates remains unchanged while the y-coordinates are negated.

Given that f(x) = x2 + 6x – 2, g(x) = x – 7, and h(x) = x + 4 find each function. (g − f)(x)

Wewaii [24]

$(g-f)(x) = -x^2-5x-5$

Step-by-step explanation:

Given functions are:

$f(x) = x^2+6x-2\\g(x) = x-7\\h(x) = x+4$

The operations on functions can be performed just as they are performed on polynomials

$(g-f)(x)=g(x)-f(x)\\=(x-7)-(x^2+6x-2)\\=x-7-x^2-6x+2\\$

Combining like terms

$=-x^2+x-6x-7+2\\=-x^2-5x-5$

Hence,

$(g-f)(x) = -x^2-5x-5$

I’m really stuck on this ☹️

fgiga [73]

Answer:

2 adults and 2 senior citizens.

Step-by-step explanation:

There are 8 children, which means we need to take the number that represents the children from the graph which is 4 and multiply it by the 8 children going.

1. 4x8=32

So we have found the total for the 8 children, however there are 4 spots left

We take the total from the #1 and add 2 adults and 2 senior citizens.

32+6+6+3+3=50

We then come to the conclusion of 2 adults and 2 seniors.

Seventy percent of kids who visit a doctor have a fever and 21% of kids have fever and sore throats . what is the probability th

Neko [114]

The probability that a kid who goes to the doctor has a sore throat given that he has a fever is <u>0.30 or 30%</u>. Computed using conditional probability.

The probability of any event A given that event B has already taken place is found using the formula P(A|B) = P(A ∩ B)/P(B). This is known as conditional probability, where P(A ∩ B) is the probability of events A and B, and P(B) is the probability of event B.

In the question, we are given that 70% of kids who visit a doctor have a fever and 21% of kids have a fever and sore throats.

We are asked to find the probability that a kid who goes to the doctor has a sore throat given that he has a fever.

We suppose the event of going to the doctor while having a fever to be B, and going to a doctor while having a sore throat to be A.

We are given that 70% of kids who visit a doctor have a fever, that is, the probability of event B, P(B) = 70% = 0.7.

We are given that 21% of kids who visit a doctor have a fever and sore throats, that is, the probability of event A and event B, P(A ∩ B) = 21% = 0.21.

We are asked to find the probability that a kid who goes to the doctor has a sore throat given that he has a fever, that is, we are asked to find the conditional probability of event A, when event B has already taken place, that is, P(A|B).

By formula, we know that:

P(A|B) = P(A ∩ B)/P(B) = 0.21/0.70 = 0.30.

Thus, the probability that a kid who goes to the doctor has a sore throat given that he has a fever is <u>0.30 or 30%</u>.
