Which classification best represents a triangle with side lengths 10 in., 12 in., and 15 in.?
acute, because 102+122>152
acute, because 122+152>102
obtuse, because 102+122>152
obtuse, because 122+152>102
Answer:
Option (1)
Step-by-step explanation:
See attached image.
The given measures form a acute angle triangle.
What is an obtuse angle triangle?An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.
Given that, a triangle with side lengths 10 in., 12 in., and 15 in.
We know that,
a²+b²=c² then triangle will be right angled
a²+b²>c² then triangle will be acute angled
a²+b²><c² then triangle will be obtuse angled
Here, a=10 inches, b=12 inches and c=15 inches
10²+12²>15²
100+144>225
244>225
Therefore, the given measures form a acute angle triangle.

Slope = 7/4
Step-by-step explanation:
You are given coordinate values and a formula that tells you what to do with them. All you need to do is put the values in the formula and do the arithmetic.
PointsYou are given points (2, -3) and (6, 4). The slope formula refers to the two points as (x1, y1) and (x2, y2). It does not matter which is which.
If we use the points in the same order they are given, then we can see that ...
x1 = 2y1 = -3x2 = 6y2 = 4FormulaUsing these values in the given formula, we find the slope to be ...
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-(-3)}{6-2}=\dfrac{7}{4}[/tex]
The slope of the line through the given points is 7/4.

A family needs to build fencing around their rectangular home and square swimming pool, depicted below.
A rectangle labeled home has its right side labeled (2 + 5 x) yards and its bottom side labeled (3 + 10 x) yards. The square, labeled pool, is smaller than the rectangle. One of its sides is labeled (2x) yards.
The total amount of fencing they need can be written as x + 10.
If x = 5;
The family needs yards of fencing for their home.
The family needs yards of fencing for their pool.
The total amount of fencing they need = 38x + 10.
Perimeter for the rectangular fencing of the home = 160 yards
Perimeter for the square fencing of the pool = 40 yards
What is the Perimeter of a Rectangle and a Square?Perimeter of a rectangle = 2(length + width)
Perimeter of a square = 4(side length).
Perimeter for the rectangular fencing of the home = 2(3 + 10x + 2 + 5x) = 2(15x + 5) = 30x + 10
Perimeter for the square fencing of the pool = 4(2x) = 8x
The total amount of fencing they need = 30x + 10 + 8x = 38x + 10.
If x = 5, then:
Perimeter for the rectangular fencing of the home = 30x + 10 = 30(5) + 10 = 160 yards
Perimeter for the square fencing of the pool = 4(2x) = 8x = 8(5) = 40 yards.

Given that the growth rate of bacteria at any time t is proportional to the number present at t and triples in 1 week.
We are required to find the number of bacteria present after 10 weeks.
let the number of bacteria present at t is x.
So,
dx/dt∝x
dx/dt=kx
1/x dx=k dt
Now integrate both sides.
[tex]\int\limits {1/x} \, dx[/tex]=[tex]\int\limits{k} \, dt[/tex]
log x=kt+log c----------1
Put t=0
log [tex]x_{0}[/tex]=0 +log c ([tex]x_{0}[/tex] shows the population in beginning)

Write an equation of a line that passes through the point (7,3) and is parallel to the line y =
y=-3x+3.0
x + 3. (5 points)
Answer:
Step-by-step explanation:
Givens
Line: y = 3x + 3
Point: (7,3)
Discussion
The easiest variation on line problems is one like this one. The reason is that all you need do is read the slope of the given line.
m = 3 of the given line. Also the slope of the new line.
What you have so far is
y = 3x + b
The point is used to find b -- the y intercept.
x = 7
y = 3
You are not given this, but what you want to think is that when x = 7, y = 3
Substitute into the new equation
3 = 3*7 + b
3 = 21 + b Subtract 21 from both sides.
3 - 21 = 21-21 + b
- 18 = b
Answer
y = 3x - 18
Answer:
-2/3x+23/3
Step-by-step explanation:
y= mx+c
where
m is the slope c is the y-intercept.
1-getting the slope:
we are given that the line we are looking for is parallel to the line
y=-2/3x+3
this means that the slope of the two lines are equal . comparing the general formula with the given line , we would find that the slope of the given lines -2/3.this means that the slope of the lines we are looking for is also -2/3
The equation of the line now becomes:y=-2/3x+c
2-getting the value of c
to get the value of c, we will use a point that belongs to the line (7,3),substitute in the equation and solve for c as follows:
y=-2/3x+c
3=(-2/3)(7)+c
3=-14/3+c
c=3+14/3
c=23/3
Based on the above, the equation of the line we are looking for is:
y=-2/3x+23/3

Step-by-step explanation:
Question 1)
The formula of a slope is (increase in y)/(increase in x), so in the graph, all we need to do is find two precise points and look at the distance difference.
1. The two points that I've found were (0,3) and (3,5). The change in y is 3 --> 5, which is 2. The change in x is 0 --> 3, which is 3.
2. The slope will be 2/3.
Question 2)
In this question, we can consider n as x and f(n) as y.
1. The two points I chose were (4, -31) and (7,-40). The change in y is -31 --> -40, which is -9. The change in x is 4 --> 7, which is 3.
2. The slope will be -9/3.
3. -9/3 can be simplified to -3 since we can divide both the numerator and the denominator by 3.
4. The final slope will be -3.
