Answer:
57
Step-by-step explanation:
since angle 3 is 57 (180-123=57) and 3 and 7 are corresponding, and corresponding angles are congruent,angle 7=57
Answer:
angle 1 and angle 7=180°[co exterior angle]
123°+ <7=180°
<7=180°-123°
<7=57°

Given y = alog(x + c) + d. What would happen to the graph if you changed the value of d? Describe both positive and negative
values.
A)
B)
Changing the value of d would cause a vertical stretch or shrink. A negative
value would also cause a reflection over the x-axis.
Changing the value of d would cause a horizontal stretch or shrink. A
negative value would also cause a reflection over the y-axis.
Changing the value of d would move the graph up and down (vertically). A
positive d value would move the graph up and a negative d value would
move the graph down.
Changing the value of d would move the graph left and right (horizontally).
A positive d value would move the graph right, and a negative d value
would move the graph left.
C)
D)
Answers
Answer: A
Step-by-step explanation:
I just took the USATESTPREP quiz and that is the answer.
Option (C) will define the changes in the graph of the function with the values of 'd'.
Given function in the question → y = alog(x + c) + d
Rules for the translation of a function,
If a function y = f(x) is shifted 'h' units upwards on y-axis, rule for the translation will be → y = f(x) + hIf the function y = f(x) is shifted 'h' units downwards, rule for the translation → y = f(x) - hHence, in the given function y = alog(x + c) + d, positive value of 'd' will define the shifting of the parent function upwards.
And for the negative value of 'd' will define the shift of the function downwards.
Option (C) will be the correct option.

Area = 150.5*sqrt(3)Perimeter = 57+7*sqrt(3)Approximate Answers:
Area = 260.673646539Perimeter = 69.12435565======================================
Explanation:
Your diagram is 100% correct. Nice work.
To get the area of the trapezoid, we could use the area of a trapezoid formula below:
A = h*(b1+b2)/2
In this case, we have,
h = 7*sqrt(3) = heightb1 = 18 = base1b2 = 25 = base2the bases are parallel to each other. The height is always perpendicular to the base. We won't use the "14" at all.
So,
A = h*(b1+b2)/2
A = 7*sqrt(3)*(18+25)/2
A = 7*sqrt(3)*21.5
A = (7*21.5)*sqrt(3)
A = 150.5*sqrt(3)
This is the exact area.
The approximate area is roughly
150.5*sqrt(3) = 260.673646539
The units for the area are in square km, or km^2. Though your teacher said for you not to include the units.
Another way to get the area of the trapezoid is to break the diagram into a rectangle and triangle as you have done so, and then find the area of each sub-piece. Adding the two smaller areas should lead to the result shown above.
-----------------------------------
To get the perimeter, we add up all of the exterior sides. We do not include the right-most vertical line that is 7*sqrt(3) km long because it is inside the figure. The horizontal segment that is 7 km long is part of the "25 km" segment, so we'll ignore that 7.
Adding the four exterior sides leads to:
7*sqrt(3)+18+14+25 = 57+7*sqrt(3)
This value is exact. It approximates to
57+7*sqrt(3) = 69.12435565
The units for the perimeter are in kilometers, and you won't have any exponent over the "km". While your teacher doesn't want the units, it's still handy to know what the units would be.
Step-by-step explanation:
solution given:
for rectangle
length [l]=18km
breadth [b]=7√3 km
for triangle
base[b1]=25-18=7km
height [h]=b=7√3km
for area :area of. (rectangle +triangle}=
l×b+1/2 b1×h=18×7√3+1/2 ×7×7√3=260.67km²
now
perimeter=sum of all sides
=18+14+25+7√3=69.12km

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,

Line of reflection → x = 1
Step-by-step explanation:
Coordinates of B → (3, 2)
Coordinates of B' → (-1, 2)
If point B is reflected across a vertical line x = a, both the points B and B' will be equidistant from the line of reflection.
Coordinates of the midpoint of the segment joining B and B'
= [tex](\frac{x_+x_2}{2},\frac{y_1+y_2}{2})[/tex]
= [tex](\frac{3-1}{2},\frac{2+2}{2})[/tex]
= (1, 2)
Line of reflection will pass through this midpoint (1, 2)
Therefore, equation of the line of reflection will be,
x = 1

On one street in Samtredia, where the houses are numbered one after the other, live Yuza, Glonti and Ramin. There are three times as many houses between Yuza and Glonti as there are between Glonti and Ramin. Ramin's house number is three times Yuza's house number. What a house the Glonts live in
If there are exactly 13 houses between Yuza and Ramin's houses. A) 12; 8) 13; a) 14; D) 15; a) 16; 3) 17.
Answers
Answer:
17Explanation:
if ramin's house number = 3 yuza's
then choices are: n×3
1 , 3 | 2 , 6 | 3 , 9 | 4 , 12 | 5 , 13 | 6 , 18 | 7 , 21
since there are 13 house between yuza and ramin
thus it's 7 , 21 (because there's 13 numbers between 7 and 21)
yuza lives in house 7
ramin live in house 21
and since houses between yuza and glonti = 3 times houses between glonti and ramin, with a ratio of 3:1
13 - 1 = 12 (we subtracted 1 for glonti's house)
3:1 , 3+1=4
12/4=3
3×3=9
hence
9 and 3 are the numbers of houses in each side with glonti in the middle
9 houses - glonti's house - 3 houses
7 + 9 = 16 (yuza's house number 7 plus 9 houses ahead)
glonti lives in the house: 16 + 1 = 17
