Someone Please Help Me. I don't understand how to do this.
1 answer:
[1] The median to the base passes through the top point (0,b) and the bottom point (0,0) since it is going straight down. The slope formula is
So, the slope of the median is (b-0)/(0-0) = b/0. Technically, this is undefined, but let's leave it this way for now.
[2] The base passes through the left point (-a,0) and the right point (a,0). Its slope must be (0-0)/(a-(-a)) = 0.
[3] We now check if the slopes are negative reciprocals. Flipping b/0 over and putting a negative sign gives:
b/0 -> - 0/b = 0
So the slopes are negative reciprocals, which means the lines are perpendicular.

<em>The question doesn't ask anything in particular, I will show the set of inequalities defined in the problem.</em>
Answer:
<em>System of inequalities:</em>
Step-by-step explanation:
<u>Inequalities </u>
The express relations between expressions with a sign other than the equal sign. Common relationals are 'less than', 'greater than', 'not equal to', and many others.
The gardening club at school has 300 square feet of planting beds to plant cucumber and tomato. Each cucumber plant requires 6 square feet of growing space and each tomato plant requires 4 square feet of growing space. We know the total area cannot exceed 300 square feet, so
Being c and t the number of cucumber and tomato plants respectively.
We also know the students want to plant some of each type of plant and have at least 60 plants. This lead us to more conditions
<em>Note: The set of inequalities shown is not enough to uniquely solve the problem. We need something to maximize or minimize to optimize c and t</em>
You have not provided the options, therefore, I cannot give an exact answer. However, I can help you with the procedures.
We are given that the ratio between the width and the length of the flag is 10 to 19.
This means that:
Therefore, to get the correct choice, all you have to do is divide the width by the length, if the result is 10/19, then the dimensions given are correct.
Examples:
For length = 190 and width = 100,
width / length = 100 / 190 = 10 / 19 .........> correct choice
For length = 1.9 and width = 1,
width / length = 1 / 1.9 = 10 / 19 .......> correct choice
Hope this helps :)

Answer:
Golf ball
Step-by-step explanation:
The formula for the surface area of a sphere is 4r². The variable is the radius. Therefore, the sphere with the smallest radius would have the smallest surface area.
