9. Which of the following is an equilateral triangle?
Answer:
d
Step-by-step explanation:
The dashes on the sides of the triangles mean that they are equal in length.
Isosceles triangle: 2 sides of equal length
Equilateral triangle: 3 sides of equal length
Triangle a doesn't have any dashes, so all the sides are different length.
Triangle b has 2 sides that each have the same number of dashes, so these sides are equal in length → Isosceles triangle
Triangle c has 2 sides that each have the same number of dashes, so these sides are equal in length → Isosceles triangle
Triangle d has 3 sides that each have the same number of dashes, so these sides are equal in length → Equilateral triangle

Graph the following function: y=−sec(x+π/4)+2
Choose the number equal to: -9 • (-1/3) A) -27 B) -3 C) 3 D) 27
integral of x/(x + 1)²(x+2)²
I suppose you mean the integral
[tex]\displaystyle \int \frac{x}{(x+1)^2 (x+2)^2} \, dx[/tex]
Break up the integrand into partial fractions:
[tex]\dfrac{x}{(x+1)^2 (x+2)^2} = \dfrac{a}{x+1} + \dfrac{b}{(x+1)^2} + \dfrac{c}{x+2} + \dfrac{d}{(x+2)^2}[/tex]
[tex]\dfrac{x}{(x+1)^2 (x+2)^2} \\ = \dfrac{a(x+1)(x+2)^2 + b(x+2)^2 + c(x+1)^2(x+2) + d(x+1)^2}{(x+1)^2 (x+2)^2}[/tex]
[tex]\dfrac{x}{(x+1)^2 (x+2)^2} \\ = \dfrac{(a+c)x^3+(5a+b+4c+d)x^2+(8a+4b+5c+2d)x + 4a+4b+2c+d}{(x+1)^2(x+2)^2}[/tex]
[tex]x = (a+c)x^3+(5a+b+4c+d)x^2+(8a+4b+5c+2d)x + 4a+4b+2c+d[/tex]
Solve for the coefficients:
[tex]\begin{cases}a+c=0 \\ 5a+b+4c+d=0 \\ 8a+4b+5c+2d=1 \\ 4a+4b+2c+d=0\end{cases} \implies a=3,b=-1,c=-3,d=-2[/tex]
So we have
[tex]\displaystyle \int \frac{x}{(x+1)^2 (x+2)^2} \, dx= \int \left(\frac3{x+1} - \frac1{(x+1)^2} - \frac3{x+2} - \frac2{(x+2)^2}\right) \, dx[/tex]
[tex]\displaystyle \int \frac{x}{(x+1)^2 (x+2)^2} \, dx= 3\ln|x+1| + \frac1{x+1} - 3\ln|x+2| + \frac2{x+2} + C[/tex]
[tex]\displaystyle \int \frac{x}{(x+1)^2 (x+2)^2} \, dx= \ln|x+1|^3 - \ln|x+2|^3 + \frac{3x+4}{(x+1)(x+2)} + C[/tex]
[tex]\displaystyle \int \frac{x}{(x+1)^2 (x+2)^2} \, dx= \boxed{\ln\left|\frac{x+1}{x+2}\right|^3 + \frac{3x+4}{(x+1)(x+2)} + C}[/tex]

Use the Pythagorean Theorem to find the distance between (-3, 4) and (6, 1). Show all calculations.
Answer:
9.48683
Step-by-step explanation:
using the formula:
d = √((x2-x1)2 + (y2-y1)2)Find the difference between coordinates:
(x2-x1) = (6 - -3) = 9
(y2-y1) = (1 - 4) = -3
Square the results and sum them up:
(9)2 + (-3)2 = 81 + 9 = 90
Now Find the square root and that's your result:
Exact solution: √90 = 3√10
Approximate solution: 9.4868

The area of a rectangle is its length times its width .
The area of a rectangle is 60 square centimeters.
its length is 7 cm longer than its width .find its width .
what is its length write an equation and solve it
Answer:
The length is 5cm.
Step-by-step explanation:
(x)(x+7) = 60
x^2 +7x = 60
x^2 +7x - 60 = 0
x^2 + 12x - 5x = 0
Answer:
[tex]lenght = 12cm \\ width = 5cm[/tex]
Step-by-step explanation:
[tex]area \: = lenght \times width \\ area = 60cm { }^{2} \\ let \: width = xcm \\ let \: lenght = (x + 7)cm \\ 60 = \: (x)(x + 7) \\ 60 = x ^{2} + 7x \\ x {}^{2} + 7x = 60 \\ x {}^{2} + 12x - 5x - 60 = 0\\ x(x + 12) - 5(x + 12) \\ (x + 5)(x + 12) \\ x = 5 \: or \: x =- 12 \\ since \: width \: cant \: be \: negative \\ width = 5cm \\ lenht = 5 + 7 = 12cm[/tex]
Zoe walks 13of a mile every 25of an hour.
How many miles does Zoey walk per hour?
Answer:
25/13 miles in an hour

So she walks 1/13 mile per 1/25 hour.
To find the miles in an hour, just multiply the 1/25 hour by 25/
1/25 hour * 25 = 1 hour.
1/13 mile * 25 = 25/13 miles in an hour

Which statement describes the basis for the proof that vertical angles are congruent?
А
Two adjacent angles are always supplementary
B.
Two adjacent angles that form a linear pair are congruent.
с
Two angles that are each supplementary to a third angle are congruent.
D
Two angles that are each complementary to a third angle are congruent.
Answer:
C
Step-by-step explanation:
On each linear pair, there is one of the Vertical angles and an angle shared between the two angles. This means we can use the fact that supplements of the same angle are congruent.
The basis for the proof vertical angles are congruent is " two angles that are each supplementary to a third angle are congruent".
What are vertical angles?Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight lines.
In the provided figure.
∠1 + ∠2 = 180 degrees ( linear pair of angles)...(i)
∠ 1 + ∠4 = 180 degrees ( linear pair of angles)...(ii)
According to transitive property, if a = b and b = c then a = c
Therefore,
∠1 + ∠2 = ∠1 + ∠4...(iii)
⇒∠2 = ∠4
Similarly, we can prove that
∠1 = ∠3
Therefore, we conclude that vertically opposite angles are always equal.
Hence, the basis for the proof vertical angles are congruent is " two angles that are each supplementary to a third angle are congruent".
Thus, statement c is correct.

two number cubes are rolled. what is the probability of getting a 1 and a 4 in either order
Answer:
1/18
Step-by-step explanation:
Each cube can have 6 outcomes, from 1 to 6.
6 × 6 = 36
The total number of outcomes is 36.
The desired outcomes are only 1, 4 and 4, 1.
There are only 2 desired outcomes.
p(1, 4 or 4, 1) = 2/36 = 1/18

How many ninth does it take to make the same amount as one third
Answer:
3
Step-by-step explanation:
you have 1/3, to find out how many ninths you have, you must multiply the denominator by three (because 3*3=9). whatever you multiply on the bottom you must multiply on the top (if you don't do that then it's not the same as 1/3 anymore)
therefore 1/3 == (1*3)/(3*3) == 3/9
if you want to know how many twelves it was then you multiply by 4 to get 12 on the bottom:
1/3 == (1*4)/(3*4) == 4/12
therefore 1/3 == 3/9 == 4/12. they are all the same fraction

A ball is placed in a machine that throws the ball up in the air. The table represents some points on the graph of a function that models the ball’s distance from the ground with respect to the time since the ball has been thrown. What is the range for this situation? A. All real numbers less than or equal to 7.66 B. All real numbers less than or equal to 1.25 C. All real numbers greater than or equal to 0 and less than or equal to 7.66 D. All real numbers greater than or equal to 0 and less than or equal to 1.25
Using it's concept, it is found that the range for this situation is given by:
C. All real numbers greater than or equal to 0 and less than or equal to 7.66.
What is the range of a function?
The range of a function is the set that contains all possible output values.
In this problem, the output values are the height of the ball, which researching the problem on the internet, is represented by a table in which the minimum height is of 0(when it hits the ground) and the maximum height is of 7.66 feet, hence the correct option is:
C. All real numbers greater than or equal to 0 and less than or equal to 7.66.
