Answer:

The amount of fencing Madisyn needs is approximately 20.77 m

Step-by-step explanation:

The coordinates of the vertices of the triangular garden are;

A(0, 6), B(6, 5), and C(5, -1)

The length of the sides of the triangle can be found through the given coordinates and the distance between coordinates formula presented as follows;

[tex]Distance \ between \ points \ given \ the \ coordinates = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

Therefore, the length of AB is [tex]\sqrt{\left (5-6 \right )^{2}+\left (6-0 \right )^{2}} = \sqrt{37}[/tex]

The length of BC is [tex]\sqrt{\left (5-(-1) \right )^{2}+\left (6-5 \right )^{2}} = \sqrt{37}[/tex]

The length of AC is [tex]\sqrt{\left (6-(-1) \right )^{2}+\left (0-5 \right )^{2}} = \sqrt{74}[/tex]

Therefore;

The amount of fencing Madisyn needs = The length of the sides of the triangular garden

The length of the sides of the triangular garden =  The length of AB +  The length of BC + The length of AC

The length of the sides of the triangular garden = √37 + √37 + √74 ≈ 20.77 m.

The amount of fencing Madisyn needs ≈ 20.77 m.

Answer:

Step 3.

Step-by-step explanation:

We need to tell the incorrect step in the given problem for the product of        (–2.5)(–8.3)

Step 1. (–2.5)(–8.3) = (–8.3)(–2.5)

Step 2:

We can write -2.5 = -(2+0.5)

(–8.3)(-(2+0.5)) = (–8.3)(-2)+(-8.3)(-0.5)

= 16.6 + 4.15

Step 3.

= 20.75

He has done an error in step 3. It should be 16.6 + 4.15 instead of (–16.6) + (–4.15). As a result, he get incorrect answer.

Step-by-step explanation:

-6.8 = negative six point eight

=====================================================

Explanation:

C is the midpoint of AB. This means AC is half as long as AB

Put another way, AB is twice as long as AC

AB = 2*AC

AB = 2*( AC )

32 = 2*( x/2 + 10 )  .... substitution

32 = 2*(x/2) + 2*10 ... distribute

32 = x + 20

x+20 = 32

x = 32-20 .... subtract 20 from both sides

x = 12

---------

If x = 12, then

AC = x/2 + 10

AC = 12/2 + 10

AC = 6+10

AC = 16

which is half of AB = 32, so it confirms our answer.

Answer:

g(f(x)) = 6x^2 + 8x - 25

Step-by-step explanation:

So, first we have to substitute f(x) into the place of x in the g(x). This will be shown as g(f(x)) (which is what we need to solve). Next, we have to substitute 3x^2 + 4x - 7 into the place of x in 2x - 11. We do this because we had to substitute f(x) into the place of x in g(x).

So this is how your equation should look, and then solve:

g(f(x)) = 2(3x^2 + 4x - 7) - 11

g(f(x)) = 6x^2 + 8x - 14 - 11

g(f(x)) = 6x^2 + 8x - 25   < ---- This is your answer

Answer:

80.24

Step-by-step explanation:

The easiest way to do this is to convert 68% to a decimal and multiply by 188. To convert a percent into a decimal, all you have to do is move the decimal point twice to the left. So...

68%=.68   Now, we can multiply by 118.

.68x118=80.24   68% of 118 is 80.24!

[tex]m = \frac{96-3 }{5-0}[/tex]

remember: slope is Δy/Δx :)

[tex]m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}[/tex]

[tex]m = \frac{96-3 }{5-0}[/tex]

[tex]m = \frac{93 }{5}[/tex]

==================================================

Explanation:

Subtract the y coordinates

y1-y2 = -96-(-86) = -96+86 = -10

Subtract the x coordinates in the same order

x1-x2 = 82-87 = -5

Divide the two differences to get the slope m

m = (y1-y1)/(x1-x2)

m = -10/(-5)

m = 2

You could also use the formula

m = (y2-y1)/(x2-x1)

to get the same result. All that matters is that you subtract in the same order for the x and y coordinates.

Answer:

The integer which represents the change in temperature from morning to afternoon is -11°

Step-by-step explanation:

Since the morning temperature in Erin's apartment was 79°, and the temperature in Erin's apartment that afternoon was 68°. If Erin turned up the temperature and the temperature in the afternoon was 68°. So, the temperature change from 79° down to 68° is thus 68° - 79° = -11°.

So, the integer which represents the change in temperature from morning to afternoon is -11°

1.00         [tex]{}[/tex]                             8

The average rate of change in grams from day 4 to day 7 is given as follows;

[tex]The \ rate \ of \ change \ from \ day \ 4 \ to \ day \ 7 = \dfrac{F(7) - F(4) }{7 - 4} = \dfrac{1.09 - 1.41 }{7 - 4} =-\dfrac{8}{75}[/tex]

The average rate of change in grams from day 4 to day 7 = -8/75 ≈ 0.11 g/day

The average rate of change in grams from day 4 to day 7 ≈ 0.11 grams/day rounded to the tenths place.

The average rate of change in grams per day from day 4 to day 7 is 0.11.

    Radioactivity in iodine-131

Grams                                 Day

1.09                                      7

1.00                                      8

Now the average rate should be

= F(7) - F(4) \ 7  - 4

= 1.09-1.41 \3

= -8\75

= 0.11

hence, The average rate of change in grams per day from day 4 to day 7 is 0.11.

Answer:

options (a), (b), (c), and (e) have the same solution as the solution of  3/5 x + 2/3 + x = 1/2 -1/5x.

Step-by-step explanation:

The given equation is

3/5 x + 2/3 + x = 1/2 -1/5x

First, rearrange the equation to have constant terms and the terms having variable on the separate side.

3/5 x + x +1/5x= 1/2 - 2/3

9/5 x = -1/6

x= -1/6 ÷ 9/5

x= -1/6 x 5/9

x= -5/54 ...(i)

Now, find the solution of all the options in the similar way:

(a) 8/5 x +2/3 = 1/2 -1/5 x

8/5 x + 1/5 x = 1/2 - 2/3

9/5 x = -1/6

x= -1/6 ÷ 9/5

x= -1/6 x 5/9

x= -5/54 which is same as the solution of the mentioned equation. [ from equation (i)]

(b) 18x + 20 + 30x = 15 – 6x

18x+30x+6x = 15 -20

54x=-5

x= -5/54 which is same as the solution of the mentioned equation. [from equation (i)]

(c) 18x + 20 + x = 15 – 6x

18x+x+6x = 15 -20

25x=-5

x= -5/25 which is not the same as the solution of the mentioned equation. [ from equation (i)]

(d) 24x + 30x = –5

54x = -5

54x=-5

x= -5/54 which is same as the solution of the mentioned equation. [ from equation (i)]

(e) 12x + 30x = –5

42x = -5

42x=-5

x= -5/42 which not is same as the solution of the mentioned equation. [ from equation (i)].

Hence, options (a), (b), (c), and (e) have the same solution as the solutions of the given equation.
