Is this a polygon or trapezoid?
Answer: No
The reason why is because this is actually a pentagon since it has 5 sides. A trapezoid must have 4 sides (making it a quadrilateral), and exactly one pair of opposite sides are parallel. The other pair of opposite sides are not parallel.
Answer:
polygon
Step-by-step explanation:
A polygon describes any shape, a trapazoid describes a specific shape with 2 parallel sides and 2 non-parallel sides (like the image below)
as we see your image does not look like the image below, so it would just be a normal old polygon

Answer 3x3.4
Step-by-step explanation:
Can some one help me answer all ten questions they are due at 10:00 I will give out brainly. Part 2
Answer:
solve for x
4x-6=26
4x=26+6
x=32/4
x=8
area of rectangle=l*b
=26*14
=364
area of triangle=b*h/2
=18.4*20.4/2
=375.36/2
=187.68 m^2
for another side of a triangle
(18.4)^2+(20.4)^2=c^2
338.56+416.16=c^2
[tex]\sqrt{754.72}[/tex]=c
27.47=c
27.5=c
now, perimeter of triangle=a+b+c
=27.5+18.4+20.4
=66.3 m^2
radius=diameter/2
=26/2
=13 ft
diameter=26 ft
circumference=2πr
=2*3.14*13
=81.64
Area of a circle=π[tex]r^{2}[/tex]
=3.14*(13)^2
=3.14*169
=530.66 ft^2
Step-by-step explanation:
The circumference of a circle is 53.38 centimeters.
What is the area in square centimeters? Use 3.14 for a.

I need help to figure out the slope and y intercept of
3x + y = -2
Answer:
The slope is -3 and the y intercept is -2
Step-by-step explanation:
3x + y = -2
Solve for y
Subtract 3x from each side
3x-3x + y =-3x -2
y = -3x-2
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -3 and the y intercept is -2
Answer:
slope is up 3 over 1, and y int is y =3x + 2
Step-by-step explanation:
y = 3x + 2
9 tickets to a theme park cost £243, how much would 7 tickets cost
Answer:
£189
Step-by-step explanation:
Divide the cost by 9 to find the cost of 1 ticket, then multiply this by 7
cost of 1 ticket = £243 ÷ 9 = £27
cost of 7 tickets = 7 × £27 = £189
A line passes through points (2,5) and (5, 14). What is the slope of this line?
We know that:
Slope of a line = change in y coordinate / change in x coordinate
We are given:
First point = (2,5)
Second point = (5, 14)
Calculating the change in y coordinate:
change in y (also represented by Δy) = second y - first y
Δy = 14 - 5
Δy = 9
Calculating the change in x coordinate:
Δx = second x - first x
Δx = 5 - 2
Δx = 3
Slope of the line:
Slope = (Δy) / (Δx)
Slope = 9 / 3 [replacing the values]
Slope = 3
What is the percent of increase from 4,000 to 10,000?
Answer:
150%
Step-by-step explanation:
Percent change = [tex]\frac{New - Old}{|Old|}[/tex] × 100%
=> [tex]\frac{10000-4000}{4000}[/tex] × 100
=> [tex]\frac{6000}{4000}[/tex] × 100 = 150% (increase)
I HAVE 10 MIN PLS HELP FIND THE VOLUME
Answer:
900

V being the volume
A being the area of the pyramids base
H being the height front he base to the top (20)
Base area is 135 (A)
135 * 20 = 2700

please help with question
Answer:
Step-by-step explanation:
Property of the perpendicular lines,
If the two lines [tex]L_1[/tex] and [tex]L_2[/tex] having slopes [tex]m_1[/tex] and [tex]m_2[/tex] are perpendicular to each other,
Then [tex]m_1\times m_2=-1[/tex]
Equation of line [tex]L_1[/tex] → y = 3x + 5 ------(1)
Equation of line [tex]L_2[/tex] → 6y + 2x = 1 ------- (2)
Slope of line [tex]L_1[/tex],
[tex]m_1=3[/tex]
Slope of line [tex]L_2[/tex],
6y + 2x = 1
6y = -2x + 1
[tex]y=-\frac{2}{6}x+\frac{1}{6}[/tex]
[tex]y=-\frac{1}{3}x+\frac{1}{6}[/tex]
Therefore, [tex]m_2=-\frac{1}{3}[/tex]
By using the property of perpendicular lines,
[tex]m_1\times m_2=3\times (-\frac{1}{3} )[/tex]
[tex]=-1[/tex]
Therefore, both the lines are perpendicular.
What is the length of the dotted line in the diagram below? Round to the nearest tenth.
Answer:
length of dotted diagonal line = 11
Step-by-step explanation:
Using the Pythagorean theorem:
length of rectangle² = 9² + 6² = 81 + 36 = 117
length of rectangle = √117 = 10.82
length of diagonal² = 2² + 10.82² = 4 + 117 = 121
length of diagonal = 11

let f(x) = 1/x-3 and g(x) = the square root of x+5. What is the domain of (f o g) (x)
Answer:
the second one
Step-by-step explanation:
Option B is correct. the required domain of the function will be expressed as [-5, 3) U (3, ∞)
The domain of a function is the input function for which a function exists.
Given the functions
f(x) = 1/x-3
g(x) = √x+5
Get the composite function (f o g) (x)
(f o g) (x) = f(g(x))
f(g(x)) = f( √x+5)
[tex]f(g(x)) =\frac{1}{\sqrt{x+5}-3 }[/tex]
According to the function gotten, we can see that the domain of the fucntion will exist for all values of x except at x = 4. The function tends to infinity at x = 4. Hence the required domain of the function will be expressed as [-5, 3) U (3, ∞)
