Answer:
The area
Step-by-step explanation:
Given
[tex]7 * 7= 49[/tex]
Required
What does 49 represent?
In the context of the question, 49 represents the area
We have:
[tex]L = 7[/tex] --- side length
So:
[tex]Area = L * L[/tex]
[tex]Area = 7 * 7[/tex]
[tex]Area = 49[/tex]
On Marlene's trip to Starved Rock, her average rate of speed for the entire five-hour trip was 62 miles per hour. For the first two hours of her trip, she kept her average speed at 50 miles per hour. Then she realized she was going to be late to meet her friend for dinner, so she started driving faster. What was her average speed for the last three hours of the trip?
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
Which function has a constant rate of change equal to -3?
The given function with a constant rate of change that equals -3 is: 2y = -6x + 10.
What is Constant Rate of Change?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

which three fractions are less than 40%
A. 3/20
B. 23/100
C. 3/5
D. 1/8
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.

If BAC = 320°, what is the measure of BC?
a. 40°
b. 80°
C. 160°
d. 320°
it also asks for the measure of angle BMC using the same photo!
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.

Compare the functions shown below: g(x) f(x) = 4x − 1 tangent function with y intercept at 0, 2 h(x) = cos(x + 2π) Using complete sentences, explain which function has the greatest y-intercept.
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).
How to know which function has the greatest y-intercept?Here we have the two functions:
f(x) = 4x - 1h(x) = cos(x + 2π).g(x) = tangent function with y-intercept at (0, 2)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.

How would you describe the graph of the function in interval 2? Select all that apply.
The graph of the function is missing and so i have attached it alongside the options.
Answer:
B & C are correct.
Step-by-step explanation:
From the attached graph, we can see that at interval 2, the line is falling down and not rising.
This means that the function is decreasing because y is decreasing while x is increasing.
Also, when both x and y are increasing, the slope is positive but when one is increasing and the other is decreasing like we have here, it means the slope is negative.
Thus, the function is decreasing and the slope is negative.

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.
What 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.

Answer:
110°32.5°60.5°63.5°Step-by-step explanation:
1. The measure of angle 1 is half the sum of the intercepted arcs:
∠1 = (1/2)(65° +155°) = 1/2(220°)
∠1 = 110°
__
2. The measure of an inscribed angle is half the measure of the intercepted arc. (This is a degenerate case of the rule in the first problem.)
∠2 = 1/2(65°)
∠2 = 32.5°
__
3. The measure of the angle at a tangent is half the measure of the intercepted arc. (This is a degenerate case of the rule in the second problem.)
∠3 = 1/2(arc QS) = (1/2)(360° -155° -84°) = (1/2)121°
∠3 = 60.5°
__
4. The measure of angle 4 is half the difference of the measures of the intercepted arcs. From problem 3, we know that arc QV is 56°.
∠4 = 1/2((155° +56°) -84°) = (1/2)127°
∠4 = 63.5°
