Question 11 is false. isometry is to be geomatrically congruent. question 15 is true.
Vesna [10]3 years ago
4 0

Question 11:

Isometry is a transformation the preserves the distance and there is no change in the distances. It includes rotation, reflection and translation . Hence the figures are congruent. So the statement is false

Question 12:

A reflection is a transformation where every point of the line is of equal distance from a particular line called the line of reflection

Hence this statement is true

Question 13:

The angle of rotation is the turning of every angle of a figure about a specific fixed point in a specific degree. Hence the statement is true

During his shift, Damion filled 8 orders in 30 minutes. If he keeps up that rate, how many orders will he fill in 7 hours?
Veronika [31]
The answer is 28
30 minutes is half of an hour so you have to divide 7 by 2 which is 3.5 and then multiply 3.5 by 8 to get 28

A medical clinic is reducing the number of incoming patients by giving vaccines before flu season. During week 5 of flu season,
8_murik_8 [283]

Answer:

f(x) = -6x +120

Step-by-step explanation:

Let's call y the number of patients treated each week

Let's call x the week number.

If the reduction in the number of patients each week is linear then the equation that models this situation will have the following form:

y = mx + b

Where m is the slope of the equation and b is the intercept with the x-axis.

If we know two points on the line then we can find the values of m and b.

We know that During week 5 of flu season, the clinic saw 90 patients, then we have the point:

(5, 90)

We know that In week 10 of flu season, the clinic saw 60 patients, then we have the point:

(10, 60).

Then we can find m and b using the followings formulas:

m=\frac{y_2-y_1}{x_2-x_1}   and b=y_1-mx_1

In this case: (x_1, y_1) = (5, 90) and (x_2, y_2) = (10, 60)

Then:

m=\frac{60-90}{10-5}

m=-6

And

b=90-(-6)(5)

b=120

Finally the function that shows the number of patients seen each week at the clinic is:

f(x) = -6x +120

First, divide the shape into two figures ( a semicircle and a rectangle)
Then, find the are or the two shapes using the area formula for a semicircle (\frac{ \pi r^{2} }{2}) and the are formula for a rectangle (base x height)
Finally, add the two areas together and you have your answer
