Answer:

18 in.²

Step-by-step explanation:

4 + 2 = 6

2 · 6 = 12 in.²

3 · 2 = 6 in.²

12 in.² + 6 in.²

18 in.²

Answer:

BC = 40º

BMC = 40º

Step-by-step explanation: Since the measure the major and minor arcs add up to 360º, just subtract 320 from 360 to find BC which is 40º. <BMC is also 40º because the measure of the arc is equal to its corresponding angle.

Answer:

g(x) has the greatest y-intercept (the graph)

Step-by-step explanation:

The y-intercept for f(x) is -1, we can easily identify it at the end of the function.

The y-intercept for g(x) is 2, we can see that's where it crosses the y-axis.

The y-intercept for h(x) is 1, we can find this by substituting 0 for x in the equation.

h(0) = cos(0+2[tex]\pi[/tex])

h(0) = cos(2[tex]\pi[/tex])

h(0) = cos(360)

h(0) = 1

[tex]\pi[/tex] = 180 when converting degrees to radians, and you can find the cosine of 360 with a calculator.

The function with the greatest y-intercept is g(x).

Here we have the two functions:

The y-intercept is the value of the function when we evaluate in x = 0, so the y-intercepts of the given functions are:

f(0) = 4*0 - 1 = -1

h(0) = cos( 0+ 2π) = 1

And for g(x), we know that the y-intercept is at y = 2.

Then we can see that the function g(x) has the greatest y-intercept.

Answer:

KL = 23

KM = 29

Step-by-step explanation:

By applying cosine rule in the given triangle KLM,

cos(∠M) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(52°) = [tex]\frac{LM}{KM}[/tex]

cos(52°) = [tex]\frac{18}{KM}[/tex]

KM = [tex]\frac{18}{\text{cos}52}[/tex]

KM = 29.24

KM ≈ 29

By applying sine rule,

sin(52°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(52°) = [tex]\frac{KL}{29.24}[/tex]

KL = 29.24[sin(52°)]

    = 23.03

    ≈ 23

KL = 23

Box Graph

Step-by-step explanation:

This is because you can see the median and quadrants, and also the edges of the dataset

The best way to display both the overall shape and individual value of the data is box graph.

"A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum. In a box plot, we draw a box from the first quartile to the third quartile. A vertical line goes through the box at the median."

"A boxplot is a standardized way of displaying the distribution of data based on a five number summary (“minimum”, first quartile (Q1), median, third quartile (Q3), and “maximum”). It can tell you about your outliers and what their values are. It can also tell you if your data is symmetrical, how tightly your data is grouped, and if and how your data is skewed."

From the graph we can conclude that

This is because you can see the median and quadrants, and also the edges of the dataset in the box graph.

Hence B is the correct option.

Answer:

A, B, D

Step-by-step explanation:

Answer:

A, B, D

Step-by-step explanation:

40% is the same as the fraction 4/10.

Compare 4/10 with 3/20 (A):

LCM of 10 and 20 is 20, so make the denominators of all fractions to 20

We now have 8/20 and 3/20

Now you can just simply look at the numerators. 3 is obviously less than 8 so option A is less than 40%

Compare 4/10 with 23/100 (A):

LCM of 10 and 100 is 100, so make all denominators 100

Now compare 40/100 and 23/100

40>23 so 23/100 is less than 40%

Compare 4/10 with 3/5 (C):

We can further reduce 4/10 to 2/5, and conveniently it has the same denoninator as 3/5. 3 is NOT less than 2, so C is ruled out.

Compare 4/10 with 1/8 (D):

LCM of 10 and 8 is 40, so we'll use that as our denominator

We now have 16/40 and 5/40.

5 is less than 16, so we include D in our answer.

Answer:

Step-by-step explanation:

Answer:

70 miles per hour

Step-by-step explanation:

Distance = speed * time

speed = distance / time

------------------------------

Total Distance

speed = 62

time = 5

62 * 5 = 310 miles

Distance travelled in first 2 hours

speed = 50

time = 2

50 * 2 = 100 miles

Remaining distance

310 - 100 = 210 miles

Speed to cover 210 miles in 3 hours

distance = 210

time = 3

210/3 = 70 miles per hour

5(4x^2-9y^2)

Step-by-step explanation:

I assume you want to simplify the expression:

20x^2-45y^2

5(4x^2-9y^2)

The given function with a constant rate of change that equals -3 is: 2y = -6x + 10.

The constant rate of change of a function = change in y / change in x. Given an equation of a function in slope-intercept form, y = mx + b, the constant rate of change is represented as m.

1. Constant rate of change of the function on the table using two pairs of values, (0, 2) and (1, 5) is:

(5 - 2)/(1 - 0) = 3/1

Constant rate of change = 3.

2. Constant rate of change of the function of the set of ordered pairs  using two pairs of values, (4, 4) and (2, 2) is:

(4 - 2)/(4 - 2) = 2/2

Constant rate of change = 1.

3. Constant rate of change of the graphed function using two points on the line, (1, 1) and (0, 3) is:

(3 - 1)/(0 - 1) = 2/-1

Constant rate of change = -2.

4. Constant rate of change of the function 2y = -6x + 10:

Rewrite the equation in slope-intercept form

2y/2 = -6x/2 + 10/2

y = -3x + 5

Constant rate of change = -3.

Therefore, the function with a constant rate of change is: 4. 2y = -6x + 10
