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

Answer:32.5

Step-by-step explanation:

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.

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.

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        

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

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

Answer:

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:

+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%.

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.
