segment EH and segment E prime H prime both pass through the center of dilation.
The slope of segment EF is the same as the slope of segment E prime H prime.
segment E prime G prime will overlap segment EG.
segment EH ≅ segment E prime H prime.
Answers
Answer:
See below and the attachedStep-by-step explanation:
Given triangle EFG:
E(0, 5), F(1, 1), G(-2, 1)Center of dilation is H(0, 1)Scale factor is k = 3The rule for this dilation is:
(x, y) → (k(x - a) + a, k(y - b) + b) (x, y) → (3x, 3(y - 1) + 1) = (3x, 3y - 2)The coordinates of E'F'G' are:
E → E' = (0, 5) → (0, 13)F → F' = (1, 1) → (3, 1)G → G' = (-2, 1) → (-6, 1)Points H and H' overlap as center of dilation at (0, 1)Options (verified with the graph):
Segment EH and segment E prime H prime both pass through the center of dilation.

How many 4 digit multiples can not be divided by 5
Answers
Answer:
1800
Step-by-step explanation:
Let us solve this question by Modular Airthmatic.
Let the lowest 4 digit number be X.
X= 1 (mod 5)
X =2 (mod 5)
X=3 (mod 5)
X =4 (mod 5)
X=1+5 t where t is any integer.
1+5 t=2 (mod 5)
5 t=1 (mod 5 )
5 is the Modular Inverse of modulo 5
t=1 (mod 5)
t =1+5 u : u= any integer.
X becomes 1+ 5 (1+5u )=6+25 u
6+25u =3 (mod 5)
25 u= -3 (mod 5)=2 (mod 5)
25 is Modular Inverse of Modulo 5
u=2 (mod 5)
u =2+5 v : v= any integer.
X becomes 6 +25 (2+5 v)=56+125 v .
56 +125 v=4 (mod 5)
125 v=-52 (mod 5)=3 (mod 5)
125 is Modular Inverse of modulo 5
v = 3 (mod 5)
v =3 +5 w where w is any integer.
For lowest 4 digit number, take
w=200
X=1003 : Lowest 4 digit number.
Take w=201
X=208 : Next number.
For 4 digit largest number, take
w=1995
X= 9978 : Largest number.

Fx + Gy = H
R are nonzero real numbers.
Select all the systems that are also guaranteed to have the solution (3,-1)
a.) (P + F)x + (Q + G)Y = R + H
Fx + Gy = H
b.) (P + F)x + Qy = R + H
Fx + (G + Q)y = H
c.) Px + Qy = R
(3P + F)x + (3Q + G)y = 3H + R
d.) Px + Qy = R

e.) Px + Qy = R

*Please explain how you got your answer because I really don't understand this!
Answers
Answer:
The systems that are guaranteed have the solution (3, -1) are;
a.) (P + F)·x + (Q + G)·y = R + H
F·x + G·y = H
d.) P·x + Q·y = R
(F - 2·P)·x + (G - 2·Q)·y = H - 2·R
e) P·x + Q·y = R
5·F·x + 5·G·y = 5·H
Step-by-step explanation:
The given system of equation are;
a) P·x + Q·y = R...(1)
F·x + G·y = H...(2)
The solution of the system of equation = (3, -1)
Adding equation (1) to equation (2) gives;
P·x + Q·y + F·x + G·y = R + H
(P + F)·x + (Q + G)·y = R + H...(3)
Therefore, given that equation (3) is obtained from equation (1) and (2) by addition, equation (3), (P + F)·x + (Q + G)·y = R + H, we have;
The system of equation;
(P + F)·x + (Q + G)·y = R + H
F·x + G·y = H, derived from the given system of equation Is bound to have the same same solution (3, -1) as the given system of equation
d.) By multiplying equation (1) by 2, we have;
2 × (P·x + Q·y) = 2 × R
2·P·x + 2·Q·y = 2·R...(4)
Subtracting equation (4) from equation (2) gives;
F·x + G·y - (2·P·x + 2·Q·y) = H - 2·R
F·x - 2·P·x + G·y - 2·Q·y = H - 2·R
(F - 2·P)·x + (G - 2·Q)·y = H - 2·R
Therefore, for the following system, obtained from the original system, we have that the solution is (3, -1);
P·x + Q·y = R
(F - 2·P)·x + (G - 2·Q)·y = H - 2·R
e) For the system of equation, we have;
P·x + Q·y = R
5·F·x + 5·G·y = 5·H
The above system of equation is obtained from the original system by multiplying equation (2) by 5, therefore the solution of the system P·x + Q·y = R, 5·F·x + 5·G·y = 5·H is the same as the solution for the original system of equations (3, -1).

Answer:

VW = 9 ft
Step-by-step explanation:
Since the tangent lines connect both circles, we know that the line VU and VX are congruent (equal). Thus, we can set them equal to each other and solve for a:
a + 4 = a² + 0.25 Set equal
a² - a = 3.75 Isolate a values
a² - a + 0.25 = 3.75 + 0.25 Complete the square
(a + 0.5)² = 4 Factor
a + 0.5 = 2 Simplify
a = 1.5
Now we need to calculate VW, but thats easy because its equal to TV, and since we know a, we can just plug it in:
((1.5) + 7.5) ft
9 ft

An object is placed at a certain distance on the principal axis of a concave mirror. The image is formed at a distance of 30cm from the mirror. Find the object distance if radius of curvature R=15cm.
Answers
Answer:
Object distance, u = -6 cm
Step-by-step explanation:
Given that,
The radius of curvature, R = 15 cm
The radius of the mirror, f = -7.5 cm
We need to find the object's distance from the mirror. The mirror's formula is used to find the object distance such that,
[tex]\dfrac{1}{f}=\dfrac{1}{u}+\dfrac{1}{v}\\\\\dfrac{1}{u}=\dfrac{1}{f}-\dfrac{1}{v}\\\\\dfrac{1}{u}=\dfrac{1}{(-7.5)}-\dfrac{1}{30}\\\\u=-6\ cm[/tex]
So, the object distance is 6 cm.
Suppose the diameter of a circle is 4units. What is its circumference?
Answers
Answer:
C = 12.6 (rounded to the nearest tenth)
Step-by-step explanation:
The formula for the circumference of a circle is C = 2πr
R = radius
The radius is the half of a diameter, so 4/2 is 2.
C = 2π(2)
C = 12.56637061

Find the equation of the line that passes through (1,3) and is perpendicular to y=1−2x. Leave your answer in the form y=mx+c
Answers
Answer:
The equation of the line that passes through (1,3) and is perpendicular to y=1−2x is y=1/2x+5/2
Step-by-step explanation:
We can rewrite the original equation as y=-2x+1
To find an equation's perpendicular slope, you take the reciprocal of it and negate it, therefore the perpendicular slope is -2 -> 1/-2 -> 1/2
So far, we have y=1/2x+b, but to find the y-intercept, b, we would need to plug in (1,3) and solve for b:
y=1/2x+b
3=1/2(1)+b
3=1/2+b
5/2=b
Therefore, your final equation is y=1/2x+5/2

Suppose the strategy of the pet food company is to increase the proportion of ... Do you think additional field training is necessary for all of the sales representatives?
Step-by-step explanation:
Yes sales representatives in Midwest and Northeast require more training
Although your question is incomplete attached below is the missing data related to your question
Given that the percentage of new stores in the Midwest and Northeast is below the 25% there will be need for an additional training for the sales representatives in these regions. while the percentage of new stores in the south is above 25% hence there won't be the need for additional sales representative training.
Percentage of new stores for after 1 month
Midwest = ( 66 / 362 ) * 100 = 18.2%
South = ( 115 / 197 ) * 100 = 58.3%
North east = ( 60 / 250 ) * 100 = 24%
Hence we can conclude that to meet up the 25% sales orders from new stores in each region additional training is required for sales representative s in Midwest and North east only.
