What is the perimeter of triangles a, b, and c? DONT EXPLAIN, JUST ANSWER ROUNDED TO THE NEAREST TENTH.
The perimeter of the triangle passing through the points A, B, C is 27.5 cm.
What is a perimeter?A triangle's perimeter and side lengths are measured in the same unit. If the sides' lengths are measured in a different unit, first convert them to that unit. Example 1: Calculate the triangle's perimeter from the information provided. A perimeter is a closed path that encloses, surrounds, or delimits a one-dimensional length or a two-dimensional shape. The circumference of a circle or an ellipse is its outermost boundary.
There are many uses in real life for perimeter calculations. The length of fence needed to enclose a yard or garden is known as the calculated perimeter.
From the figure,
The triangle is passing through the points A(4, 0), B(-6, 5), C(3, 3)
By using distance formula, we have to calculate the lengths of AB, BC, CA
Length of AB=√(-6-4)²+(5-10)²
=√125
Length of BC=√(3+6)²+(3-5)
=√85
Length of CA=√(3-4)²+(3-10)²
=√50
The perimeter of a triangle=AB+BC+CA
=√125+√85+√50
=11.18+9.22+7.07
=27.47≈27.5
Therefore, the perimeter of the triangle is 27.5 cm.

Use point-slope form to write the equation of a line that passes through the point
(−11,−14) with slope 1.
The equation of the line that passes through the point (−11,−14) is y = x - 3.
What is the slope of the line?
A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).
We have,
The line that passes through the point (−11,−14)
With Slope (m) = 1,
The general equation of a straight line is
y = mx + c,
where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
so here,
y = mx + c,
(-14) = 1(-11) + c
c = -14 + 11
c = -3

The solution of a system of linear inequalities is the intersection of the solutions to each inequality. Every point in the intersection region satisfies all inequalities in the system. Describe how you know which region, if any, represents the solution to a system of linear inequalities
Answer:
To determine which region represents the solution to a system of linear inequalities, you need to graph each inequality on the same coordinate plane and then find the intersection of the regions that satisfy each inequality. This intersection is the solution to the system of linear inequalities, as every point in this region satisfies all of the inequalities in the system.
To graph the solution, you can use a number line for each variable and plot the inequalities as points or lines on the coordinate plane. For example, if the system of linear inequalities is given by the equations y > 2x + 3 and y < -x + 5, you can plot the lines y = 2x + 3 and y = -x + 5 on the coordinate plane and find the intersection of the two lines. This intersection represents the solution to the system of linear inequalities, as every point in this region satisfies both inequalities.
Another way to find the solution to a system of linear inequalities is by using algebra to solve the system. This involves writing the equations in standard form, eliminating variables, and solving for the remaining variable. The solution can then be written as a set of ordered pairs that represent the points on the coordinate plane that satisfy the system of linear inequalities.
In either case, the solution to a system of linear inequalities is the region of the coordinate plane that satisfies all of the inequalities in the system.

The exponential is an example of a mathematical function that is useful in determining if something is increasing or decreasing exponentially is the exponential function. As implied by its name, an exponential function uses exponents. But take note that an exponential function does not have a variable as its exponent and a constant as its base (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
a sample of a radioactive substance decayed to 93% of its original amount after a year.
The half-life is t for which:
exp(-0.067 t) = (0.5)

a) The linear equation is given as follows: 10x + 6y = 240.
b) The graph of the linear function is given by the image shown at the end of the answer.
How to define the linear function?The first step is defining the linear function is identifying the variables, which are given as follows:
Variable x: number of hats purchased.Variable y: number of mittens purchased.You hope to have $240 in sales. Hats cost $10 and mittens cost $6, hence the equation is given as follows:
10x + 6y = 240.
The x-intercept is the point (x,0), hence:
10x = 240
x = 24.
The y-intercept is the point (0,y), hence:
6y = 240
y = 40.

Suppose S is the set of integers that are multiples of 3, and T is the set of integers that are odd. Prove that |S| = |T| by constructing a bijection between S and T.
The bijection could be defined from the set of numbers and it is proved.
We can define a bijection f from S to T as follows: for any integer x in S, let f(x) = x + 1.
To show that f is a bijection, we need to prove that it is both injective and surjective.
To prove that f is injective, suppose f(x) = f(y) for some x, y in S. Then x + 1 = y + 1, which means x = y. Thus, f is injective.
To prove that f is surjective, let y be an arbitrary element of T. Since y is odd, we can write y = 2n + 1 for some integer n. Now consider the element x = 3n in S. We have f(x) = x + 1 = 3n + 1 = y, so f is surjective.
Therefore, f is a bijection from S to T, so |S| = |T|.

A rectangular field is to have an area of and is to be surrounded by a fence. The cost of the fence is dollars per meter of length. What is the minimum cost this can be done for?.
The minimum cost for the area can be fenced is $1920
It is given that the area of the rectangular field is 900 m²
Let the length of one side of the field be x m
Therefore, the length of the other side will be
900/x
The perimeter of the rectangular field
= 2(length + breadth)
= 2(x + 900/x)
= 2x + 1800/x m
Therefore, the cost of fencing will be
$(32x + 28800/x )
Let f(x) = 32x + 28800/x
We need to minimize f(x)
Differentiating with respect to x and equating it to 0 gives us
32 - 28800/x² = 0
or, x² = 28800/32
or, x² = 900
or, x = 30
This is because the length cannot be negative hence -30 cannot be a value
Now
f''(x) = 57600/x³
f''(30) = 2/1333
Since f"(x) is positive, x = 30 is the minimum value of x for which the cost is minimum.
Hence, the minimum cost will be

In this scenario, the sign of the slope of the graph of this plane's equation, with time being represented on the horizontal axis and elevation on the vertical axis are as follows;
The plane is cruising: the slope of the graph would be zero because it is moving at a constant speed.The plane is descending: the slope of the graph would be negative because it is decelerating.The plane is ascending: the slope of the graph would be positive because it is accelerating.In conclusion, the slope of a graph would be positive because there is an increase in the variables on the cartesian coordinate.

The length of one side is 20 ft and the other side of the yard is 33 ft.
Let the length of the side opposite to the house be x ft.
We know that the yard to be fenced is rectangular. Hence the opposite sides of the yard are going to be equal.
It is given that the side opposite to the wall is 13 ft less than the length f the other two sides.
Hence the length of the side adjacent to the house will be
(x + 13) ft
The fencing needs to be done on these three sides. We already know that the length that has been fenced is 86 ft.
Hence, we get
x + x + 13 + x + 13 = 86
or, 3x + 26 = 86
or, 3x = 86 - 26
or, 3x = 60
or, x = 60/3
or, x = 20.
Hence the length of one side is 20 ft and the length of the other side is
