Remark

Draw a line  across the east and west farthest points. If you count the lower left point as 0,0, I am talking about 1,6 and 7,6 What that does is divide the figure into a triangle and a trapezoid.

Triangle

The base goes from x = 1 to x = 7 when that new line is introduced which is 6 units parallel to the x axis.

The height goes from 4,4 to 4,6 which is 2 units in the y direction.

So the area = 1/2 (2)*(6) = 6 units.

Trapezoid.

h = 3       derived from 4,3 to 4,6 which is 3 points  6 - 3 = 3

b1 = 6     That's the line you just drew in.

b2 = 4     That comes from 2,3 to 6,3   6-2 = 4

Area = 1/2 (b1 + b2) * h

Area = 1/2 (6 + 4)* 3

Area = 5 * 3 = 15

Total Area = 15 + 6 = 21

Answer:

113.04

π×6^2 is the solution of this

Answer:

area = 113.1 m²

Step-by-step explanation:

area = PiR²

area = (Pi)(6²) = 113.1 m²

Answer:

no it is not able to be factored

Answer:

when there are no parentheses around the base, this being -2 we put parentheses around the the 2 and the exponent so it will look like -(2^6) making whatever answer you get negative.

when you put parentheses around the base (-2)^6 you will get 64

Step-by-step explanation:

One hundred and twenty-two AFLP markers were mapped using an IR64 x Azucena rice doubled-haploid (DH) population. The distribution of these mapped markers was monitored across a set of 48 diverse landraces of rice. Strong statistical associations were observed between 960 of the 7381 possible pairs of markers across the diverse material.

Givens

r = 5

h = 30

Formula

SA = 2*pi*r^2 + 2pi*r*h

Solution

SA = 2*3.14 *5^2 + 2*3.14 * 5* 30

SA = 50*3.14 + 300*3.14

SA = 157 + 942

SA = 1099 square inches.

Answer:

Average rate of change = 1

Step-by-step explanation:

Average rate of change of a function between x = a and x = b is defined by,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

We have to find the average rate of change of the function in the interval 2 ≤ x ≤ 4

Therefore, average rate of change of the function = [tex]\frac{f(4) - f(2)}{4-2}[/tex]

From the graph attached,

f(4) = 4

f(2) = 2

Average rate of change = [tex]\frac{4-2}{4-2}[/tex]

                                        = 1

Therefore, average rate of change of the function in the given interval is 1.

Answer:

1/4

Step-by-step explanation:

If there are two pies and eight friends, then 4 friends split each pie. I know this because if you divide eight by two (because there are 8 friends and 2 pies) then you get 4, which means then 4 friends split each pie. You would then figure out how many slices you need to split each pie into. Since there are 4 people per pie, you would split each pie into 4 sections. Each friend would get 1/4 of a pie.

I hope this makes sense to you. If you need any more help, please let me know. I'm always happy to help! :]

Answer: the vertex is 1,7/2

Step-by-step explanation: this is the answer because first you label the first one a the second one b and the last one c then if you find the axis of symmetry by doing [tex]\frac{-b}{2(a)\\}[/tex] you will have your x for the vertex then plug in your x into the equation where ever there is a x tat where you plug it in then you will have the right answer...

Answer:

$80+18%= $94.4

Answer: 6 cm^2

Step-by-step explanation:

The area base when the trapezoid-based right prism has a volume of [tex]30\ cm^3[/tex], 6cm ,5 cm, 1 cm should be 6.

Here we assume

a = 6

b = 5

c = 1

Now we know that

area

[tex]= (a + b)\div 2 \times c\\\\= (6 + 5)\div 2 \times 1\\\\= 5.5\times 1[/tex]

= 6

Hence, The area base when the trapezoid-based right prism has a volume of [tex]30\ cm^3[/tex], 6cm ,5 cm, 1 cm should be 6.

The unit rate of demonstrated in the graph will be 4.5 miles per hour. Then the correct option is B.

The rate is the proportion of how much something is to the unit. For instance - Assuming that the speed of the vehicle is 20 km/h it implies the vehicle voyages 20 km in 60 minutes.

The incline is the proportion of rising or falling and running. The contrast between the ordinate is called rise or fall and the distinction between the abscissa is called run.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

From the graph, take two points from the graph which are (0, 0) and (27, 6).

Then the unit rate demonstrated in the graph will be given as,

Rate = (27 - 0) / (6 - 0)

Rate = 27 / 6

Rate = 4.5 miles per hour

The unit rate of demonstrated in the graph will be 4.5 miles per hour. Then the correct option is B.

Answer:

2 x 7

Step-by-step explanation:

a * b = 14

2a + 2b = 18

(a * b)/b  = 14/b Dividing both sides by b

a = 14/b

Substitute a in the perimeter equation

2(14/b) + 2b = 18

28/b + 2b = 18

2b - 18 + 28/b = 0

Multiply both sides by b

2b^2 - 18b + 28 = 0

Divide both sides by two

b^2 - 9b + 14 = 0

The Factors of 14 include -2 and -7 which add up to -9

(b - 2) * (b - 7) = 0

This has two answers because b can be either the side that is 2 long or 7 long, so there's no need to go back and solve for a.

Answer:

x = 51

Step-by-step explanation:

It looks like alt int. angles (correct me if im wrong)

3x - 40 = 2x + 11

x = 51

Answer:

x = sqrt 5x - 2/2

Step-by-step explanation:

2(x-1)(x+1) = 5x

2(x^2 - 1) = 5x

2x^2 - 2 = 5x

2x^2 = 5x - 2

2x = sqrt 5x - 2

x = sqrt 5x - 2/2
