Part 2 - ∠EGF = 105° Part 3 - ∠D = 65________________________________________________Step-by-step explanation for Part-2:
We know that:
∠EFG = 32°∠AEG = 137°∠EFG + ∠FGE + ∠GEF = 180°Work:
∠EFG + ∠FGE + ∠GEF = 180°32 + ∠FGE + (180 - 137) = 180°=> 32 + ∠FGE + 43 = 180°=> 75 + ∠FGE = 180°=> ∠FGE = 180 - 75=> ∠FGE = ∠EGF = 105°Hence, the measure of ∠EGF is 105°.

________________________________________________There were 25 runners competing in a race. The number of runners who finished ahead of Paula was one-third the number of runners who finished after her. In what place did Paula finish?
Answer:
7th Place
Step-by-step explanation:
Seeing as how the number of runners in front of Paula is [tex]\frac{1}{3}[/tex] the number of runners behind her,
Assign the number of people behind Paula to a variable:
# of people behind Paula = b, which means
# of people ahead of Paula = [tex]\frac{1}{3}[/tex] b
Use the variable to make an equation:
b (people behind Paula) + [tex]\frac{1}{3}[/tex] b (people ahead of Paula) + 1 (Paula) = 25
b + [tex]\frac{1}{3}[/tex] b + 1 = 25
Solve for b:
b + [tex]\frac{1}{3}[/tex] b + 1 = 25
b + [tex]\frac{1}{3}[/tex] b = 24
[tex]\frac{4}{3}[/tex] b = 24
b = 18
If there are 18 people behind Paula, there are [tex]\frac{1}{3}[/tex] * 18 people in front of her, which is 6; This puts Paula in 7th place.

Which numbers represent the first 5 members selected?
24000 75983 62200 91518 11198 88936
A 24, 07, 59, 62, 20

C 24, 75, 36, 22, 51
D 24, 75, 98, 36, 22
Answer:a
Step-by-step explanation:
The numbers representing the first 5 members selected is option A. 24, 07, 59, 62, 20.
What does a Random Number Table define?A random number table is a table of digits which are used to select random samples.
The random number table can be used as described below.
Given population size is 78 out of which 10 members has to be selected.
Each member has been numbered from 01 to 78.
The given line from a random number table is,
24000 75983 62200 91518 11198 88936
We have to select the first 5 members.
Select consecutive two digits in order since the number we assigned consists of two digits.
Select two digits from the first. It is 24.
First member selected is one with number 24 assigned.
Next two digits are 00. Since there are no member with 00 as the number assigned, skip it.
Next two digits are 07. Select it.
Next two digits are 59. Select it
Next two digits are 83, which is not included in the set 01 to 78. Skip it.
Next two digits are 62. Select it.
Next two digits are 20. Select it.
So the selected members are 24, 07, 59, 62, 20.
Hence the selected members using the random number table are 24, 07, 59, 62, 20.

Answer:
The answer is 30.86
Step-by-step explanation:
Answer:
30.86
Step-by-step explanation:
Let f be a twice differentiable function with f(1) = -1, S'(1) = 2, and f"(1)=0. Let gbe a function whose derivative is given by g'(x) = x? [25 (x)+ f'(x)] for all x. a. Write an equation for the line tangent to the graph of fat x=1.
Hi there!
a.
At x = 1 for the function 'f', we are given that:
f'(1) = 2
f(1) = -1 ⇒ (1, -1)
We can use the point-slope formula to make a line with the information:
y - y₁ = m(x - x₁)
Plug in the derivative for 'm' and the coordinates:
y - (-1) = 2(x - 1)
y + 1 = 2x - 2
y = 2x - 3
B.
A point of inflection is where the second derivative changes signs, or f''(a) = 0.
According to the information given, f''(1) = 0, so there IS a point of inflection at this point.
C.
Solve for g'(1) using the given equation:
g'(x) = x²[2f(x) + f'(x)]
Use the given information:
g'(1) = (1²)[2f(1) + f'(1)] = (1)(-2 + 2) = 0
The slope is 0, so the graph is a horizontal line.
We are given that g(1) = 3, so:
y = 3 is our equation for the tangent line.
D.
We can use the power rule to solve.
[tex]\frac{dy}{dx}f(x) * g(x) = f'(x)*g(x) + g'(x)* f(x)[/tex]
Let:
[tex]f(x) = x^2\\g(x) = 2f(x) + f'(x)[/tex]
Solve:
[tex]2x(2f(x) + f'(x)) + x^2(2f'(x) + f''(x)) \\ \\=4xf(x) + 2xf'(x) + 2x^2f'(x) + x^2f''(x)\\\\ = 4xf(x) + (2x + 2x^2)f'(x) + x^2f''(x)\\\\= 4xf(x) + 2x(x + 1)f'(x) + x^2f''(x)[/tex]
We can find this expression's equivalent for x = 1, and use this value to determine whether there is a local min or max at this value.
[tex]g''(1) = 4(1)(-1) + 2(1)(2)(2) + (1^2)(0) = -4 + 6 = 2[/tex]
Thus, since the second derivative is positive at this point, there is a LOCAL MIN at x = 1.

-8-8x^2=-31
how to solve for x
Answer:
x = ± [tex]\sqrt{\frac{23}{2\sqrt{2}}}[/tex]
Step-by-step explanation:
-8 - 8x^2= -31
Since this is a quadratic, it needs to be factored.
First, move the x to the other side:
-8 = 8x^2 - 31
Then, get the x alone by first adding 31:
23 = 8x^2
then dividing by 8:
x^2 = 23/8
Finally, square root both sides and remember the even roots property:
x = ± [tex]\sqrt{\frac{23}{8}}[/tex]
and simplify the root 8:
x = ± [tex]\sqrt{\frac{23}{2\sqrt{2}}}[/tex]

Step-by-step explanation:
1/8=2/5Y
multiplying both side by 5/2
5/2x1/8=2/5Yx5/2
Y=5/16
Y=0.3125
Why is the measure angle of y
Step-by-step explanation:
x + x + x = 90°
3x = 90°
x = 90/3 = 30
x = 30°
now,
apply angle sum property to find the value of y
as, x = 30
so,
30 + 90 + y = 180
120 + y = 180
y = 180 - 120 = 60
y = 60° ans.
therefore, option B is correct

Four adults and three children go to a theatre for $74, whereas two adults and five children are charged $58. Find the price of an adult’s ticket and a child’s ticket.
Answer:
adult’s ticket = $14 || child’s ticket = $6
Step-by-step explanation:
Let adults ticket cost be a , children's ticket cost be c
4a + 3c = $74 ........from theory 1
2a + 5c = $58 ..........from theory 2
Making a the subject for both:
4a + 3c = $74
4a = 74 - 3c
a = ( 74 - 3c )/4 ........equation 1
2a + 5c = $58
2a = 58 - 5c
a = ( 58 - 5c )/2 ........equation 2
Solving simultaneously:
( 58 - 5c )/2 = ( 74 - 3c )/4
4( 58 - 5c ) = 2( 74 - 3c )
232 - 20c = 148 -6c
232 -148 = -6c + 20c
84 = 14c
c = $6
Each children's ticket cost is $6
Then the adults ticket cost: ( 74 - 3c )/4
: ( 74 - 3(6) )/4
: $14

O A
a demand table

a demand schedule
Answer:you would use a demand chart
Step-by-step explanation:
Answer:
C. A demand schedule.
Step-by-step explanation:
The demand curve is a visual representation of how many units of a good or service will be bought at each possible price. It plots the relationship between quantity and price that's been calculated on the demand schedule, which is a table that shows exactly how many units of a good or service will be purchased at various prices.
As you can see in the chart below, the price is on the vertical (y) axis, and the quantity is on the horizontal (x) axis. This chart plots the conventional relationship between price and quantity. The lower the price, the higher the quantity demanded. As the price decreases from p0 to p1, the quantity increases from q0 to q1.
