Scale Factor:
Answer:
No, the above polynomials aren't similar as they don't have a constant scale factor
The following polygons given in the question are not similar .
What are similar polygons ?Similar polygons are those polygon which have the similar shapes but with different size and dimensions. Similar polygons have also the scaling factor ration equal.
How to identify whether the given polynomials are similar?There are two polygons given in the question LMNO and WXYZ .
For both of the polygons, we are checking the adjacent sides of the polygons.
The value of LM = 35 but for the other polygon , its adjacent side WX = 18.
Similar LO = 63 and WZ = 10 .
Also the adjacent angles are not equal as ∠MNO = 50° and ∠ZWX = 50° .
Therefore, the polygons given have different scaling factor.
Thus, the following polygons given in the question are not similar .

Answer:
Graph B
Step-by-step explanation:
Look at the first part of the function: 2-x , -7 ≤ x ≤ 5
If you put -7 in place of x you'll have:
2 - (-7) = 2 + 7 = 9
In the graph A, the point x = -7 have a y = 8, so cannot be the graph A. and it have to be graph B

Solve for x. Leave your answer in simplest radical form.
Answer:
sqrt 51
Step-by-step explanation:
You should use the pythagorean theorem, which states a^2+b^2=c^2. So the missing side length for the smaller triangle is sqrt{2^2+3^2}=sqrt{4+9}=sqrt{13}. And the side length x is sqrt{8^2-sqrt{13}^2}=sqrt{64-13}=sqrt{51}

Find angle CBA
pls help
Answer:
40
Step-by-step explanation:
u can draw a line at point c parallel to line ab
angle at d and lower part of c is interior angle so u can find the value at lower part of c that is 180-145=35
so point c 75-35=40 is upper part of point c
upper part of c and angle b is alternate angle so both angle are the same
angle cba is 40
Answer:
<CBA = 40°
Step-by-step explanation:
If AB is parallel to DE, you can make an irregular pentagon by continuing AB and drawing a line perpendicular to DE. The sum of the interior angles of a pentagon is 540. You can use this to solve for the supplement of <CBA, then subtract that from 180. (I’m sure there’s an easier way, but I cant think of one right now).
540-90-90-145-75=x
140=x
<CBA=180-140= 40°

what is simplfiled for x^8 y^2 / x^3 y^9
Answer:
x^5/y^7
Step-by-step explanation:
x^8 y^2 / x^3 y^9
We know that a^b/ a^c = a^(b-c)
Simplify the x terms
x^8 / x^3 = x^(8-3) = x^5
Simplify the y terms
y^2 / y^9 = y^(2-9) = y^-7
We know a^-b = 1/a^b
y^-7 = 1/y^7
Put the terms back together

Answer:
length = 48 feet , width = 32 feet
Step-by-step explanation:
Using
2W + 2L = 160 with W = L - 16 , then
2(L - 16) + 2L = 160 ← distribute and simplify left side
2L - 32 + 2L = 160
4L - 32 = 160 ( add 32 to both sides )
4L = 192 ( divide both sides by 4 )
L = 48
Substitute L = 48 into W = L - 16
W = 48 - 16 = 32
Thus length = 48 feet and width = 32 feet
Answer:
l = 48 cm
w = 32 cm
Step-by-step explanation:
length = l
Width w= l - 16
Perimeter = 160 ft
2*(l + w) = 160
2*(l + l -16) = 160
2*(2l - 16) = 160
Use distributive property
2*2l - 2*16 = 160
4l - 32 = 160 {add 32 to both sides}
4l = 160 + 32
4l = 192 {Divide both sides by 4}
l = 192/4
l = 48 cm
W = 48 - 16 = 32 cm

Find the measure of the missing angles.
100°
b =
C=
Answer:
<b = 80
<c = 80
Step-by-step explanation:
<b and 100 form a straight line so they add to 180
<b +100 =180
<b = 180-100
<b = 80
angles b and c are vertical angles and vertical angles are equal
<c = <b = 80

come on ! you can literally see that in the chart.
how many parts of the gray 3/8 are covered by the gray 1/4 ?
2 parts = 2/8 are clearly covered by 1/4.
2/8 is what part of 3/8 ?
it is the same question as "2 is what part of 3" ?
is 2 a quarter (1/4) of 3 ? no, 1/4×3 = 3/4 and not 2.
is 2 one third (1/3) of 3 ? no, 1/3 of 3 = 1/3×3 = 1 and not 2.
is 2 two thirds (2/3) of 3 ? ah, 2/3 × 3 = 2. that is correct !
is 2 three quarters (3/4) of 3 ? no, 3/4×3 = 9/4 and not 2.
once you have the same denominator, you can easily compare the numerators and ignore the denominators for such problems.

(I think I remember your other information correctly.)
Step-by-step explanation:
I think you said you were given
*Integral from x=-5 to x=0 of g was -14
*Integral from x=-5 to x=6 of g was 6
Asked to find integral( g(x) + 2 , from x=0 to x=6)
Yes this can be split into two integrals:
Integral(g(x), x=0 to x=6) + Integral(2, x=0 to x=6)
The last integral is easier... the antiderivative or 2 is 2x. So evaluate 2x as the limits and subtract. Always plug in the top limit first. 2(6)-2(0)=12-0=12
Let's start with the bigger interval from x=-5 to x=6 which was 6... and since we want to get rid of the interval from x=-5 to x=0 to find the integral of g from x=0 to 6, all we must do is do 6-(-14)=20.
Integral( g(x) + 2 , from x=0 to x=6)
=
Integral(g(x), x=0 to x=6) + Integral(2, x=0 to x=6)
=
20+12
=
32
