Answer:

Here you go :)

Step-by-step explanation:

The area covered by the signal is 181.37 m²

Here we can see that the area covered by the signal is the fourth of a circle of radius R = 15.2m

The area of a circle of radius R is given by:

A = 3.14*R²

Then the area of a fourth of a circle is:

A = (3.14/4)*R²

Replacing the value of the radius in the formula we will get:

A =  (3.14/4)*(15.2m)² = 181.37 m²

When x = 13, the equation that is true is option D) 5(x - 9) = 20.

To determine which equation is true when x = 13, we can substitute the value of x into each equation and see which equation holds true. Let's go through each option:

A) 3(18 - x) = 67

Substituting x = 13:

3(18 - 13) = 67

3(5) = 67

15 = 67

The equation is not true when x = 13. Therefore, option A is false.

B) 4(9x) = 23

Substituting x = 13:

4(9*13) = 23

4(117) = 23

468 = 23

Again, the equation is not true when x = 13. Therefore, option B is also false.

C) 2(x - 3) = 7

Substituting x = 13:

2(13 - 3) = 7

2(10) = 7

20 = 7

Once again, the equation is not true when x = 13. Therefore, option C is false as well.

D) 5(x - 9) = 20

Substituting x = 13:

5(13 - 9) = 20

5(4) = 20

20 = 20

Finally, the equation is true when x = 13. Therefore, option D is true.

Note: the translated questions is

X = 13, which equation is true?

Answer: D) The graph of y = f(x) will shift down 13 units.​

Step-by-step explanation:

Let's define the transformations of translations.

If we start with a function f(x):

For A > 0.

An horizontal translation of A units to the right is written as g(x) = f(x - A)

An horizontal translation of A units to the right is written as g(x) = f(x + A).

A vertical translation of A units up is written as g(x) = f(x) + A

A vertical translation of A units down is written as g(x) = f(x) - A.

In this question we have the transformation:

y = f(x) - 13

This is a translation of 13 units down, then the correct option is:

D) The graph of y = f(x) will shift down 13 units.​

If Natalie puts 4 pears in each bag, she will be able to sell a total of 12 bags of pears at the Saturday market.

To represent the number of bags of pears, b, that Natalie sells at the Saturday market, we can use the following equation:

b = total_number_of_pears / pears_per_bag

In this equation, "total_number_of_pears" represents the total quantity of pears Natalie has, and "pears_per_bag" represents the number of pears she puts in each bag.

Given that Natalie has a total of 48 pears, we can substitute the value into the equation:

b = 48 / pears_per_bag

Now, we need to determine the number of pears she puts in each bag. The information provided states that Natalie sells bags of pears, and each bag is sold for $5. However, the specific number of pears per bag is not given. To proceed, we need this information.

Let's assume that Natalie puts 4 pears in each bag. We can substitute this value into the equation:

b = 48 / 4

Simplifying the equation gives:

b = 12

So, if Natalie puts 4 pears in each bag, she will be able to sell a total of 12 bags of pears at the Saturday market.

It's important to note that the specific value of "pears_per_bag" will affect the final result. If Natalie puts a different number of pears in each bag, the equation will yield a different number of bags sold.

The rate of change of this simple index over 1 week is - 8.81%

The rate of change is the ratio of the difference in the value of the simple index to the original value of simple index.

Total value of the simple index at day 1 = (8000 x $4.25) + (5000 x $2.90) + (2000 x $6.40) = $61,300

Total value of the simple index at day 8 = (8000 x $3.90) + (5000 x $2.50)+(2000*6.10)  = 55900

the rate of change of this simple index over 1 week

= (55900-61300)/ 61300          * 100 %

Thus, the answer is 5/6.

The greater unit rate of the two functions is 2. The greater y-intercept of two functions is 6.

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

From the given table, (0, 5) and (5, 15)

Here, slope(m)=(y2-y1)/(x2-x1) =(15-5)/(5-0)

= 10/5

= 2

Substitute m=2, (x, y)=(0, 5) in y=mx+c, we get

5=2(0)+c

c=5

Substitute m=2, c=5 in y=mx+c, we get

y=2x+5 --------(I)

From the graph, (-4, 0) and (0, 6)

Here, slope(m)=(6-0)/(0+4)

= 3/2

= 1.5

Substitute m=1.5, (x, y)=(0, 6) in y=mx+c, we get

6=1.5(0)+c

c=6

Substitute m=1.5, c=6 in y=mx+c, we get

y=1.5x+6 --------(II)

Answer:

f(x) = 3(x − 9)^2 + 4

To find the inverse of f(x), first we denote: y = 3(x - 9)^2 + 4, we then find a way to express x in term of y.

     y = 3(x - 9)^2 + 4

<=> y - 4 = 3(x - 9)^2

<=> (y - 4)/3 = (x - 9)^2

<=> sqrt[(y - 4)/3] = x - 9

<=> x = sqrt[(y - 4)/3] + 9

Denote left side is g(x), and variable y on the right side is x, we have:

g(x) = sqrt[(x - 4)/3] + 9

g(x) is inverse of f(x)

Here, (x - 4)/3 must be not a negative number (because of the definition of square root (sqrt) of a real number)

=> x - 4 >= 0 or x >= 4

=> The restriction domain of g(x), which is the inverse of f(x) is x >= 4

The total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

From the figure, the area of triangles can be calculated using the:

Area = (1/2)height×base length

Area of three triangle = 1/2(4×6) + 1/2(6×4) + 1/2(4×6)

Area of three triangle = 1/2(24×3) = 36 square units

Area of the figure = area of three triangle + area of the rectangle

= 36 + 6×4

= 60 square units

Thus, the total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

Answer:

0.35% of students from this school earn scores that satisfy the admission requirement.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The combined SAT scores for the students at a local high school are normally distributed with a mean of 1479 and a standard deviation of 302.

This means that \(\mu = 1479, \sigma = 302\)

The local college includes a minimum score of 2294 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement?

The proportion is 1 subtracted by the pvalue of Z when X = 2294. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{2294 - 1479}{302}\)

\(Z = 2.7\)

\(Z = 2.7\) has a pvalue of 0.9965

1 - 0.9965 = 0.0035

0.0035*100% = 0.35%

0.35% of students from this school earn scores that satisfy the admission requirement.

ABCD is a kite.

Step-by-step explanation:

Given vertices of quadrilateral ABCD:

To find the exact lengths of the sides of the quadrilateral, use the distance formula.

\(\boxed{\begin{minipage}{7.4 cm}\underline{Distance between two points}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two points.\\\end{minipage}}\)

\(\begin{aligned}AB&=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\&=\sqrt{(-3-4)^2+(3-5)^2}\\&=\sqrt{(-7)^2+(-2)^2}\\&=\sqrt{49+4}\\&=\sqrt{53}\\\end{aligned}\)

\(\begin{aligned}BC&=\sqrt{(x_C-x_B)^2+(y_C-y_B)^2}\\&=\sqrt{(-6-(-3))^2+(-13-3)^2}\\&=\sqrt{(-3)^2+(-16)^2}\\&=\sqrt{9+256}\\&=\sqrt{265}\\\end{aligned}\)

\(\begin{aligned}CD&=\sqrt{(x_D-x_C)^2+(y_D-y_C)^2}\\&=\sqrt{(6-(-6))^2+(-2-(-13))^2}\\&=\sqrt{(12)^2+(11)^2}\\&=\sqrt{144+121}\\&=\sqrt{265}\\\end{aligned}\)

\(\begin{aligned}DA&=\sqrt{(x_A-x_D)^2+(y_A-y_D)^2}\\&=\sqrt{(4-6)^2+(5-(-2))^2}\\&=\sqrt{(-2)^2+(7)^2}\\&=\sqrt{4+49}\\&=\sqrt{53}\\\end{aligned}\)

A kite has two pairs of adjacent equal sides.
