Step-by-step explanation:
(x1,y1)(x2,y2)
(2,8) (0,0)
0-8 / 0-2 = -8/-2
simplify -8/-2 = 4
Answer:
4.
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
- that is rise / run.
We use the points (2, 8) and (2,0) ( - the last point is vertically below (2,8) and is on the x axis)
Here y2 = 8, y1 = 0, x2 = 2 and x1 = 0.
So the slope = (8-0)/(2-0)
= 4

Answer:
TanQ=20/21
Step-by-step explanation:
since we know that
TanQ= opposite/Adjacent
so we are going to calculate for the adjacent using Pythagoras theorem
a^2+b^2=c^2
20^2+b^2=29^2
400 + b^2=841
b^2=841-400
√b^2=√441
b=21
so our tanQ= opp/adj
tanQ=20/21

The measures of three sides of a triangle are 14 inches, 5 inches, and 12 inches. Determine whether the triangle is a right triangle. Show work to support your reasoning.
Answer:
we have the sides of the triangle, which are 14, 5, and 12 inches.
in a right angled triangle, the longest side is the hypotenuse
and pythagoras’s theorem is used/ can be used.
a^b + b^2 = c^2 where c is the hypotenuse
so we know a = 12, b = 5, and c = 14
now check whether the statement is true
we should get c = 14 if it’s a right triangle
12^2 + 5^2 = c^2
144 + 25 = c^2
169 = c^2
√169 = 13 = c
so since we got 13 for c and it’s not 14
we know that this isn’t a right angled triangle

Step-by-step explanation:
[tex] = \lim \limits_{x \to - 4} \frac{ \sqrt{x + 20} - \sqrt{12 - x} }{ {x}^{2} + 3x - 4 } [/tex]
[tex] = \lim \limits_{x \to - 4} \frac{ \sqrt{x + 20} - \sqrt{12 - x} }{(x + 4)(x - 1)} \times \frac{ \sqrt{x + 20} + \sqrt{12 - x} }{ \sqrt{x + 20} + \sqrt{12 - x } } [/tex]
[tex] = \lim \limits_{x \to - 4} \frac{ {( \sqrt{x + 20} )}^{2} - {( \sqrt{12 - x} )}^{2} }{(x + 4)(x - 1)( \sqrt{x + 20} + \sqrt{12 - x} )} [/tex]

[tex] = \lim \limits_{x \to - 4} \frac{2x + 8}{(x + 4)(x - 1)( \sqrt{x + 20} + \sqrt{12 - x} )} [/tex]
[tex] = \lim \limits_{x \to - 4} \frac{2 \cancel{(x + 4)}}{ \cancel{(x + 4)}(x - 1)( \sqrt{x + 20} + \sqrt{12 - x} )} [/tex]
[tex] = \lim \limits_{x \to - 4} \frac{2}{(x + 1)( \sqrt{x + 20} + \sqrt{12 - x} )} [/tex]
[tex] = \frac{2}{( - 4 + 1)( \sqrt{ - 4 + 20} + \sqrt{12 + 4} ) } [/tex]
[tex] = \frac{2}{( - 3)( \sqrt{16} + \sqrt{16}) } [/tex]
[tex] = \frac{2}{( - 3)(4 + 4)} [/tex]

Damaris cut three strips of paper to use as the three sides of a triangle. The first two strips are 6 inches and 9 inches long, respectively. Which length could be the length of the third side of Damaris’s triangle?
Using triangle concepts, it is found that the length of the third side of Damaris’s triangle could be any value greater than 3 inches and less than 15 inches.
In a triangle, the sum of the lengths of the two smaller sides has to be greater than the length of the greater side.
Considering 6 inches and 9 inches the smallest sides:
[tex]x < 6 + 9[/tex]
[tex]x < 15[/tex]
Considering 9 inches as the greater side:
[tex]x + 6 > 9[/tex]
[tex]x > 9 - 6[/tex]
[tex]x > 3[/tex]
The length of the third side of Damaris’s triangle could be any value greater than 3 inches and less than 15 inches.

The length of a rectangle is 3 ft longer than its width.
If the perimeter of the rectangle is 70 ft, find its length and width.
Answer:
The length is 16 and the width is 19.
Step-by-step explanation:
We'll represent width with the letter w, and length with l.
w = l + 3
The perimeter is all four sides, so perimeter = 70ft = (2w) + (2l)
We will replace w with l + 3.
70 = 2(l + 3) + (2l)
2 (l + 3) = (l + 3) + (l + 3)
and 2l = l + l, so
70 = l + 3 + l + 3 + l + l = 4l + 6
We subtract 6 from both sides.
64 = 4l
then we divide both sides by 4
16 = l
Remember width = length + 3, so
16 + 3 = w
19 = w
Just to check:
2(length) + 2(width) = perimeter
2(16) + 2(19) = 70
32 + 38 = 70
Trayvon enters a competition to guess how many balls are in a barrel. Trayvon’s guess is 63 balls. The actual number of balls is 60. What is the percent error of Trayvon’s guess?
Answer:
+5%
Step-by-step explanation:
Trayvon's guess, 63, is 3 higher than the actual number of balls. We compare 3 to 60: 3/60, or 1/20. Multiplying this result by 100%, we get 5%. The percent error is 5%.
What is the radius of a sphere with a volume of 28526^3 to the nearest tenth of an inch?
graph f(x)=3x+5 and g(x)=3x-2
Answer:
Two parallel lines
Step-by-step explanation:
the slopes are the same: slope = 3
f(x) 3x + 5 g(x) = 3x - 2
Pick at least three x values and find their corresponding values for y. Remember the f(x) and g(x) represent y
f(x) = 3x + 5 g(x) = 3x - 2
y = 3x + 5 y = 3x - 2
let x = 0 y = 3(0) + 5 y = 3(0) - 2
y = 5 y = -2
Ordered pair (0, 5) (0, -2)
Let x = 1 y = 3(1) +5 y = 3(1) - 2
y = 8 y = 1
ordered pair (1, 8) (1, 1)
Let x = -1 y = 3(-1) + 5 y = 3(-1) - 2
y = 2 y = -5
ordered pair (-1, 2) ( -1, -5)
Locate the ordered pairs and draw the graph on the lines.
you will graph two parallel lines

Which choice shows the product of 23 and 39?
(23)(39) = 897
23 · 39 = 777
23 + 39 = 62
23 x 39 = 677
Answer:
(23)(39)
Step-by-step explanation:
When you have to look for the "product" of two numbers, it implies multiplication.
With this, get rid of 23 + 39 = 62 as an answer.
Now simply enough, multiply 23 by 39,
23 * 39 = 897
Meaning that A. (23)(39) = 897 is the answer.
Prouvez par récurrence que quel que soit n EN\{0}, on a
1/1.2 + 1/2.3 + …. + 1/ n.(n+1) v= 1- 1/n+1
The left side is equivalent to
[tex]\displaystyle \sum_{k=1}^n \frac1{k(k+1)}[/tex]
When n = 1, we have on the left side
[tex]\displaystyle \sum_{k=1}^1 \frac1{k(k+1)} = \frac1{1\cdot2} = \frac12[/tex]
and on the right side,
[tex]1 - \dfrac1{1+1} = 1 - \dfrac12 = \dfrac12[/tex]
so this case holds.
Assume the equality holds for n = N, so that
[tex]\displaystyle \sum_{k=1}^N \frac1{k(k+1)} =1 - \frac1{N+1}[/tex]
We want to use this to establish equality for n = N + 1, so that
[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = 1 - \frac1{N+2}[/tex]
We have
[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = \sum_{k=1}^N \frac1{k(k+1)} + \frac1{(N+1)(N+2)}[/tex]
[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = 1 - \frac1{N+1} + \frac1{(N+1)(N+2)}[/tex]
[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = 1 - \frac{N+2}{(N+1)(N+2)} + \frac1{(N+1)(N+2)}[/tex]
[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = 1 - \frac{N+1}{(N+1)(N+2)}[/tex]
[tex]\displaystyle \sum_{k=1}^{N+1} \frac1{k(k+1)} = 1 - \frac1{N+2}[/tex]
and this proves the claim.
