For "downhill" lines, if the rise is negative, the run must be
?
9514 1404 393
Answer:
positive
Step-by-step explanation:
When considering the slope of a line, we usually choose "rise" and "run" so that "run" is positive, and "rise" measures the vertical change as one moves from left to right.
If we assume that "downhill" lines refers to lines that go from upper left to lower right (downhill to the right), then the rise is negative while the run is positive.
__
Additional comment
Here, we assume a line is considered to be "downhill" if it has negative slope. In the real world, "downhill" is the direction the ball rolls under the influence of gravity. That direction might be behind you, or to your left, instead of in front of you or to the right.
Definitions are important in math. "Downhill" is not a term that is widely used to describe lines, so we have to guess the intended meaning here.

Emelyn is comparing the rates of two different gardening companies for her camp site. The table below shows the rates for Log Edge Landscaping. Log Edge Landscaping Hours Worked 1.5 3 3.5 4.5 Total Cost $26 $44 $50 $62 The equation below represents the rates for Gatewood Gardening Services, where x represents the hours worked and y represents the total cost, in dollars. Compare the rates of both companies, and graph the relationship that represents the cost for the company with a greater rate of change.
Answer:
See Explanation
Step-by-step explanation:
Given
Edge Landscaping:
[tex]\begin{array}{cc}{Hours} & {Total} & {1.5} & {\$26} & {3} & {\$44} & {3.5} & {\$50} & {4.5} & {\$62} \ \end{array}[/tex]
The rates (m) of the above table is calculated using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
From the table, we have the following points
[tex](x_1,y_1) = (1.5,26)[/tex]
[tex](x_1,y_1) = (4.5,62)[/tex]
So, the rate is:
[tex]m = \frac{62 - 26}{4.5 - 1.5}[/tex]
[tex]m = \frac{36}{3.0}[/tex]
[tex]m = 12.0[/tex]
This means that the rate of edge landscaping is $12.0 per hour
The equation for Gatewood is not given. Hence, the rate cannot be calculated. However, the general procedure of calculating rates from a linear equation is as follows;
A linear equation is of the form:
[tex]y = mx + b[/tex]
Where:
[tex]m \to slope\ or\ rates[/tex]
In other words, if the equation is:
[tex]y = 20x + 5[/tex]
Then the rate is: 20 ($20/hour)
If the equation is: [tex]y = 10x + 5[/tex]
Then the rate is 10 ($10/hr)
Next, is to compare the rates;
For Edge landscaping, we have:
[tex]m = 12.0[/tex]
For Gatewood, we have:
[tex]m = 10[/tex] ------------ assume the equation is: [tex]y = 10x + 5[/tex]
Compare the rates:
[tex]12 > 10[/tex]
Hence, Edge landscaping has a greater hourly rate

one half plus one third
Answer:
0.83333333333
Step-by-step explanation:
One-half plus one-third equals 5/6 or 0.8333.
Given that:
Expression: 1/2 + 1/3
To add one-half (1/2) and one-third (1/3), to find a common denominator and then add the fractions together.
The least common denominator (LCD) of 2 and 3 is 6. To convert the fractions to have a common denominator of 6, multiply the numerator and denominator of 1/2 by 3, and the numerator and denominator of 1/3 by 2:
1/2 × 3/3 = 3/6
1/3 × 2/2 = 2/6
Now that the fractions have a common denominator of 6, add them:
3/6 + 2/6 = 5/6
3/6 + 2/6 = 0.8333
Therefore, one-half plus one-third equals 5/6 or 0.8333.

Given that ABCD is a rectangle, find the perimeter of the figure below. Round your answer to the nearest tenth. *
Options

19.7 ft
21 ft
24.4 ft
9514 1404 393
Answer:
(b) 19.7 ft
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of the 3 straight sides and half the circumference of a 3-ft circle.
P = 6 + 3 + 6 + (1/2)(π)(3) = 15 +3/2π ≈ 19.712 . . . feet
The perimeter is about 19.7 feet.
Find the dicontinuities of the function.
f(x) =
x2 + 12x + 27
x2 + 4x + 3
.
There is a removable discontinuity at
(
,
).
Answer:
Step-by-step explanation:
I'm assuming you meant to type in
[tex]f(x)=\frac{x^2+12x+27}{x^2+4x+3}[/tex] because you can only have removable discontinuities where there is a rational (fraction) function. Begin by factoring both the numerator and denominator to
[tex]f(x)=\frac{(x+3)(x+9)}{(x+1)(x+3)}[/tex] and cancelling out like terms would have us eliminating the (x + 3). That is where there is a removable discontinuity. It leaves a hole. The other discontinuity, (x + 1) doesn't cancel out so it is a non-removable discontuinity, which is a vertical asymptote.
The removable discontinuity is at -3. There is no y value at x = -3 (remember there's only a hole here), because -3 causes the denominator to go to 0 and we all know that having a 0 in the denominator of a fraction is a big no-no!!!
Two angles are complementary ( the sum of the two angles is 90°). The sum of the first angle plus twice the second angle is 150°. Find the measures of the angles.
Answer:
30 and 60
Step-by-step explanation:
Let x represent the first angle
(x) the sum of the first angle plus twice of the second angle 2(90 - x)
x + 180 - 2x = 150
180 - 150 = 2x - x (we export like terms to the same side of the equation)
30 = x is the measure of the first angle and since the second angle is complementary to this the measure of the second angle is 90 - 30 = 60

What are the domain and range of this function?
===========================================
Explanation:
The domain is the set of allowed x inputs. We can plug in any x value we want as the graph stretches on forever to the left and to the right. There aren't any division by zero errors or any issues like that to worry about, so that's why we don't kick out any x values from the domain.
The domain being all real numbers translates to the interval notation [tex](-\infty, \infty)[/tex] which is basically saying [tex]-\infty < x < \infty[/tex]
-----------------------------------
The range is the set of y outputs possible. The graph shows that y = 1 is the smallest y output, so y = 1 or y can be greater than this.
In short, [tex]y \ge 1[/tex] is the range which converts to the interval notation [tex][1, \infty)[/tex] which is the same as saying [tex]1 \le y < \infty[/tex]

A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the plant f(n), in cm, after n days:
f(n) = 12(1.03)n
What is the average rate of change of the function f(n) from n = 3 to n = 10, and what does it represent? (4 points)
Answer:
The average of rate was of 0.4314 cm/day, which means that on average, during this interval, the plant grew by 0.4314 cm each day.
Step-by-step explanation:
Average rate of change:
The average rate of change of a function f(x), from x = a to x = b, is given by:
[tex]A = \frac{f(b)-f(a)}{b-a}[/tex]
In this question:
[tex]f(x) = 12(1.03)^n[/tex]
From n = 3 to n = 10
[tex]a = 3, b = 10[/tex]
[tex]f(b) = f(10) = 12(1.03)^{10} = 16.13[/tex]
[tex]f(a) = f(3) = 12(1.03)^{3} = 13.11[/tex]
Average rate of change:
[tex]A = \frac{f(b)-f(a)}{b-a} = \frac{16.13-13.11}{10-3} = 0.4314[/tex]
The average of rate was of 0.4314 cm/day, which means that on average, during this interval, the plant grew by 0.4314 cm each day.
