b) Definition of angle
c) Definition of bisect
d) Angle Addition Postulate
Answers
We have been given that PQ bisects [tex]\angle RPS[/tex]. In the second statement of the given two-column proof, the statement is [tex]\angle RPQ\cong\angle QPS[/tex].
This implies that the two angles formed by bisection of angle [tex]\angle RPS[/tex] by the line PQ are equal. We know that the reason for this is simple. It is the definition of bisection of an angle that the two smaller angles formed will be equal to each other.
Therefore, the reason for statement 2 of the given two column proof is c) Definition of bisect

y = 8x
sub in (2,16)...x = 2 and y = 16
16 = 8(2)
16 = 16 (correct)...so (2,16) is a solution
y = 8x
subbing in (1,8)...x = 1 and y = 8

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 108.7-cm and a standard deviation of 0.6-cm. For shipment, 22 steel rods are bundled together.
Find the probability that the average length of rods in a randomly selected bundle of steel rods is less than 109.1-cm.
Round to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 2 decimal places are accepted.
Answers
Let x be the lengths of the steel rods and X ~ N (108.7, 0.6)
To get the probability of less than 109.1 cm, the solution is computed by:
z (109.1) = (X-mean)/standard dev
= 109.1 – 108/ 0.6
= 1.1/0.6
=1.83333, look this up in the z table.
P(x < 109.1) = P(z < 1.8333) = 0.97 or 97%

where "n" is how many sides are there in the polygon, now, notice, this polygon has 7 sides, so is a heptagon, so the sum of its interior angles will be 18(7 - 2) or 900.
now, subtract all other angles from 900, and what's leftover is "x".
Answer:
Measure of angle x is:
119°
Step-by-step explanation:
The sum of all interior angles in a polygon having n sides is:
180°(n - 2)
Now, this polygon has 7 sides.
So the sum of its interior angles will be= 180°(7 - 2)
= 900°
i.e. 129°+129°+123°+122°+x+141°+137°=900°
or 781°+x=900°
or x=900°-781°
or x=119°
Hence, Measure of angle x is:

In the year 2016, the estimated population of Canadian geese in a city was 750. The Canadian geese population is expected to grow at a rate of 12% each year. What is the Canadian geese population in 2022? Round the answer to the nearest whole number.
Answers
Keywords:
population, Canadian geese, growth rate
For this case, we must find the population of Canadian geese for the year 2022, taking into account that in 2016 the estimated population of geese was 750 and as additional data, the population of geese has a growth rate of 12% each year.
Then, we started finding the Canadian geese population for 2017, for this we make a rule of three:
750 -----------> 100%
x --------------> 12%
DOnde "x" represents the number of geese that is added to the base population of 2016.
[tex]x = \frac {12 * 750} {100}\\x = 90[/tex]
Thus, the geese population for 2017 is: [tex]750 + 90 = 840[/tex]
We find the population of Canadian geese for the year 2018, following the previous steps since the annual growth rate is constant:
840 -----------> 100%
x --------------> 12%
where "x" represents the number of geese that is added to the base population of the year 2017.
[tex]x = \frac {12 * 840} {100}\\x = 100.8[/tex]
Thus, the geese population for 2018 is: [tex]840 + 100.8 = 940.8[/tex]
We found the population of Canadian geese for the year 2019, following the previous steps since the annual growth rate is constant:
940.8 -----------> 100%
x --------------> 12%
Where "x" represents the number of geese that is added to the base population of the year 2018.
[tex]x = \frac {12 * 940.8} {100}\\x = 112.896[/tex]
Thus, the geese population for 2019 is: [tex]940.8 + 112.896 = 1053.696[/tex]
We find the population of Canadian geese for the year 2020, following the previous steps since the annual growth rate is constant:
1053.696 -----------> 100%
x --------------> 12%
Where "x" represents the number of geese that adds to the base population of the year 2019.
[tex]x = \frac {12 * 1053.696} {100}\\x = 126.44[/tex]
Thus, the geese population for 2020 is: [tex]1053.696 + 126.44 = 1180.12[/tex]
We found the population of Canadian geese for the year 2021, following the previous steps since the annual growth rate is constant:
1180.12 -----------> 100%
x --------------> 12%
Where "x" represents the number of geese that is added to the base population of the year 2020.
[tex]x = \frac {12 * 1180.12} {100}\\x = 141.6[/tex]
Thus, the population of geese for 2021 is:[tex]1180.12 + 141.6 = 1321.7[/tex]
We found the population of Canadian geese for the year 2022, following the previous steps since the annual growth rate is constant:
1321.7 -----------> 100%
x --------------> 12%
[tex]x = \frac {12 * 1321.7} {100}\\x = 158.6[/tex]
Where "x" represents the number of geese that adds to the base population of the year 2021.
Thus, the population of geese for 2022 is: [tex]1321.7 + 158.6= 1480.3[/tex]
ANswer:
The population of Canadian geese by 2022 will be approximately 1480 geese

Multiply the outer -2 with the inner x to get -2 times x = -2x
Multiply the outer -2 with the inner term 10 to get -2 times 10 = -20
So overall, -2(x+10) = -2x-20
--------------------------------------------
So that's how we're able to go from this [tex]-2(x+10) \ge 75[/tex] to this [tex]-2x-20 \ge 75[/tex]
The only thing that changes is the left side. The inequality sign will not flip. It only flips if we multiply both sides by a negative number.

A long distance phone company charges $1.01 for the first 25 minutes of a call, then $0.09 for each additional minute. A call cost $9.56 how long did it last?
Answers
1.01+.09x=9.56 Solve for x. Start buy subtracting 1.01 from both sides.
.09x=8.55 Divide both sides by .09
x=95 The call was 95 additional minutes. So...
25+95=120 120 minutes in total. Check your answer by substituting x...
1.01+.09(95)=9.56
1.01+8.55=9.56
9.56=9.56
I hope this helps!
Final answer:
Subtracting the initial charge from the total cost and then dividing the remainder by the cost per additional minute, we find that the call lasted for 120 minutes.
Explanation:
The student is asking how long a phone call lasted based on the cost of the call with a given rate structure. We know that the first 25 minutes cost $1.01 and each additional minute costs $0.09. The total cost of the call was $9.56. To determine the duration of the call, we need to calculate the cost of the additional minutes beyond the first 25, and then find out how many of those minutes were used.
Subtract the initial charge from the total cost: $9.56 - $1.01 = $8.55.
Divide the remaining cost by the cost per additional minute: $8.55 / $0.09 = 95 minutes.
Add the initial 25 minutes to the additional minutes: 25 + 95 = 120 minutes.
Therefore, the call lasted for 120 minutes.

$10,000 is compounded semiannually at 12% interest for t years. what expression represents the amount of money after t years?
Answers
0.12t=10,000(2)
The expression that represents the amount of money after t years when $10,000 is compounded semiannually at 12% interest is [tex]10000(1.06)^{(2t)}[/tex].
The amount of money after t years can be represented by the following expression:
[tex]A = P(1 + \frac{r}{n})^{(n*t)}[/tex]
Where:
A is the amount of money after t years
P is the principal amount (initial investment), which is $10,000 in this case
r is the interest rate, which is 12% expressed as a decimal (0.12)
n is the number of times interest is compounded per year, which is semiannually (2 times per year)
Substituting the values into the expression, we have:
[tex]A = 10,000(1 + \frac{0.12}{2})^{(2*t)}[/tex]
Simplifying further, we get:
[tex]A = 10000(1.06)^{(2t)}[/tex]
Therefore, the expression that represents the amount of money after t years when $10,000 is compounded semiannually at 12% interest is [tex]10000(1.06)^{(2t)}[/tex].

which inequality best represents the situation of you must be at least 52 inches tall to ride the water ride
Answers
Answer:
Option C is the correct choice.
Step-by-step explanation:
We have been given a graph and we are asked to find the correct option which represents the inequality for the situation of one must be at least 52 inches tall to ride the water ride.
At least 52 inches means one should not be less than 52 inches. This means the length of one should be 52 inches or any number greater than 52 inches.
Let us see our given inequalities one by one.
A) Our first inequality represents height less than or equal to 52, which means that one should be at-most 52 inches, therefore, 1st inequality is not true for our given situation.
B) Our 2nd inequality represents height less than 52, therefore, 2nd inequality is not true for our given situation.
C) We can see from our inequality represented in option C that height is greater than or equal to 52 inches. It is including 52 (at least) and greater heights than 52, therefore, option C is the correct choice.
D) Option D shows an inequality that represents heights greater than 52 as it is not including 52, therefore, option D in not a correct choice.
Suppose an isosceles triangle ABC has A = 45° and b = c = 4. What is the length of a^2?

180 - 45 = 135
135/2 = =67.5
A = 45
B = 67.5
C = 67.5
a = ?
b = 4
c = 4
Since we know two sides and all three angles, we can use the law of sines to find a.
b/sin B = a/sin A
4/(sin 67.5) = a/(sin 45)
a = 4(sin 45)/(sin 67.5)
a^2 = (4(sin 45)/(sin 67.5))^2
a^2 = 9.37
