What is the y-coordinate of point C?
OA A
OB. -5
Oc. -6
OD. -7
Answer:
[tex]y = -5[/tex]
Step-by-step explanation:
Given
[tex]B = (7,-3)[/tex]
[tex]C = (6,y)[/tex]
[tex]A = (4,-9)[/tex]
Required
The y coordinate of C
Since A, B and C are on the same line, the slope of AB and the slope of AC will be the same.
Slope (m) is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
For AC
[tex]A = (4,-9)[/tex] [tex]C = (6,y)[/tex]
[tex]m = \frac{y - -9}{6 - 4}[/tex]
[tex]m = \frac{y +9}{2}[/tex]
For AB
[tex]A = (4,-9)[/tex] [tex]B = (7,-3)[/tex]
[tex]m = \frac{-3 --9}{7-4}[/tex]
[tex]m = \frac{-3 +9}{3}[/tex]
[tex]m = \frac{6}{3}[/tex]
[tex]m = 2[/tex]
So, we have:
[tex]m = \frac{y +9}{2}[/tex] and [tex]m = 2[/tex]
[tex]m = m[/tex]
[tex]\frac{y +9}{2} = 2[/tex]
Multiply both sides by 2
[tex]y +9 = 4[/tex]
Solve for y
[tex]y = 4-9[/tex]
[tex]y = -5[/tex]
Hence, the y coordinate of C is -5
Tiya earns $7 an hour mowing her neighbor's lawn.
Part A: Create two variables and determine which is dependent and which is independent for this situation. (4 points)
Part B: List three ordered pairs to show the values of the two variables. (3 points)
Part C: Write an equation to represent the relationship between the two variables. (3 points)
Part A) The independent variable is the hours that Tiya mows her neighbor's lawn, and we can denote that with x. It's the variable that isn't affected by other factors. The dependent variable is the amount of money Tiya earns, which we can denote with y. The dependent variable is the variable that is affected by other factors. The amount of money Tiya makes depends on how many hours she works.
Part B) As stated in part A, x is the hours and y is the money earned. The ordered pairs are in (x, y) form, with x being the hours and y being the money earned. For example, if Tiya worked one hour, x would be 1. As she earns 7 dollars per hour, she would earn 7 dollars (1*7), which is y. Therefore, one ordered pair could be (1, 7). Two hours would give Tiya 14 dollars, so we have another pair of (2, 14). Three hours would give Tiya 21 dollars, so we have (3, 21). We can do that for any numbers.
Part C) With every hour, Tiya earns 7 dollars. In order to find y, which is the amount of money totally earned, we multiply x by 7 (7 dollars per hour). Therefore, y = 7x.
The variables are:
x = number of hours that she worksy = how much she gets paid.And the proportional relation that relates them is:
y = $7*X
How to define variables?
The only information that we know is that Tiya earns $7 per hour, so the only variables that we can use are money and time.
The independent variable will be time, because she can decide how much time can she work. The dependent variable is money, because how much she earns depends on how many hours she works.
How to get ordered pairs?The ordered pairs are of the form (number of hours, money).
Some examples for this case are:
(0 hours, $0)(1 hour, $7)(2 hours, $14).How to get the equation?We define the variables.
x = number of hours that she worksy = how much she gets paid.Because she wins $7 per hour, the proportional equation will be:
y = $7*x

Answer:
517.2
Step-by-step explanation:
It has sides you're not seeing so don't forget those.
You need to find the area of the front, back, two sides, and bottom
Front & back:
6*5.2* 1/2
31.2/2 = 15.6 for each
Sides:
27*6 = 162 each
Bottom:
6*27 = 162
162+162+162+15.6+15.6= final answer
Answer: B
Step-by-step explanation:
First, you do 5.2 times 6 divided by two which is 15.6. Now you do 15.6 times two since there are two triangles and get 31.2. Now you do 27 times 6 times two and get 324 + 31.2 = 355.2. Lastly, you do 27 times 6 to get 162. 162+355.2 = 517.2

What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
18x−6y=12
Writing the above equation in slope- intercept form
6y = 18x - 12
y= 18x /6 - 12/ 6
y= 3x - 2.
So, the slope of perpendicular line is -1/3 and passes through (6, 1)
y= mx+ c
1 = -1/3 (6) + c
1 = -2 + c
c= 3
Hence, the y- intercept is 3.

Answer:
u = 143º
Step-by-step explanation:
Sum of angles in a triangle is 180

x + 143 = 180
x = 37º
x and u are supplementary angle which total 180
u + 37 = 180
u = 143º

line f has a slope of -3. what is the slope of the line that is parallel to line f
Answer:
A line parallel has the same slope, so -3
The slope of the line that is parallel to line f is -3.
The given line f has a slope of -3.
We need to find the slope of the line that is parallel to line f.
What are parallel lines slope?The slope of parallel lines. The slope of parallel lines is equal. The parallel lines are equally inclined with the positive x-axis and hence the slope of parallel lines is equal. If the slopes of two parallel lines are represented as [tex]m_{1}[/tex], [tex]m_{2}[/tex] then we have [tex]m_{1}=m_{2}[/tex].
So, the slope of the parallel line=-3

1a. [1 mark] The price per kilogram of tomatoes, in euros, sold in various markets in a city is found to be normally distributed with a mean of 3.22 and a standard deviation of 0.84. Find the price that is two standard deviations above the mean price.
Answer:
The price that is two standard deviations above the mean price is 4.90.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
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 p-value, we get the probability that the value of the measure is greater than X.
Mean of 3.22 and a standard deviation of 0.84.
This means that [tex]\mu = 3.22, \sigma = 0.84[/tex]
Find the price that is two standard deviations above the mean price.
This is X when Z = 2. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2 = \frac{X - 3.22}{0.84}[/tex]
[tex]X - 3.22 = 2*0.84[/tex]
[tex]X = 4.9[/tex]
The price that is two standard deviations above the mean price is 4.90.
