Triangle ABC has coordinates A(-4,1), B(0,-2),and C(4,1).
The perimeter of ∆ABC is ___ units.
9514 1404 393
Answer:
18 units
Step-by-step explanation:
The distance formula is used to find the distance between two points:
d = √((x2 -x1)² +(y2 -y1)²)
For AB, the distance is ...
d = √((0 -(-4))² +(-2 -1)²) = √(16 +9) = √25 = 5
The distances between the other pairs of points can be found the same way. We have elected to let a spreadsheet do the math. It tells us the perimeter of triangle ABC is 18 units.
Answer: 18 units

What is the equation of the line
Answer:
y=-6/7x-3
Step-by-step explanation:
On a graph, I plotted (7,-9) and the used the slope given but it was very off. On the slope -6/7x one of the plots is (7,-6). From the two lines, just go down 3 times and you would reach your plot again. What I mean is, do -6- 3=-9 so the answer is '- 6/7x-3. I used demos graphing calculator & calculator to make sure that my answer was 100% correct. You can use it too if you don't wan to use graph paper.

I need these answers
Answer:
You are correct with all of your answers so far,...
Step-by-step explanation:
5) = 0 (-17 + 20 = 3,... 3 + -3 = 0)
6) = -34 (-34 + 25 = -9,... -9 + -25 = -34)
9) = -4 (7 + -11 = -4)
Chow,...!
Answer:
for question 5 the answer is 0.
for question 6 the answer is -34.
for question 9 the answer is -4.
Step-by-step explanation:
question 5: -17+20 can also be written as 20-17 which is equal to 3. Next, we have to add 3 with -3. 3+(-3) is the same as 3-3 which equals 0.
question 6: 25-25 = 0, and the remainder is -34.
question 9: 7-11 can also be written as -11+7, which is equal to -4.
Express (16^3)^1/2
in simplest radical form.
Answer:
I assume you mean 16^(1/3) i.e. the cube root of 16
I am also assuming you mean the real cube root because, as you may know, every non-zero real number has three cube root - one real and two complex conjugates.
Since 16 = 8 x 2 and 8 = 2³ then (2³ x 2)^1/3 = (2³)^1/3 x 2^1/3 = 2 x 2^1/3
You might check that the cube root of 16 is about 2.52 which is twice the cube root of 2

the larger lf ferret food is on sale at the super pet mart 89. Ferroza made the following table. Explain to ferroza why the cost of food at super pet mart is not a proportional relationship
Proportional relationships are relationships that can be represented using a uniform or constant rate. The cost of food is not a proportional relationship because it does not use a uniform rate.
The missing table is as follows:
[tex]\begin{array}{cc}Bag&Cost\\0&0\\5&17.5&30&89\end{array}[/tex]
Let:
[tex]x \to[/tex] Bag
[tex]y \to[/tex] Cost
First, we calculate the slope (m) of the table using:
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (5,17.5)[/tex]
The slope (m) is as follows:
[tex]m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m=\frac{17.5 - 0}{5-0}[/tex]
[tex]m=\frac{17.5}{5}[/tex]
[tex]m=3.5[/tex]
Also, calculate the slope (m) using the following points
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (30,89)[/tex]
The slope (m) is as follows:
[tex]m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{89 - 0}{30 - 0}[/tex]
[tex]m = \frac{89}{30}[/tex]
[tex]m = 2.97[/tex]
The calculated slopes are not the same. i.e.
[tex]3.5 \ne 2.97[/tex]
Hence, the cost of food is not a proportional relationship because it does not use a uniform rate.
