Answer:
D. CircumcenterStep-by-step explanation:
Those cities are located on the vertices of the triangle.
The circumcenter of a triangle is the point equidistant from the three vertices of the triangle.
Correct option is D.
Answer:
Incenter
Step-by-step explanation:
1) Since the newest location must be at the same distance from that Triangle's verticles.
2) Then, according to that, the point that it's central and equidistant is the incenter, Because the incenter is at the center of an inscribled circle.
3) Hence, the answer is Incenter.

A sample of a radioactive isotope had an initial mass of 360 mg in the year 1998 and
decays exponentially over time. A measurement in the year 2004 found that the
sample's mass had decayed to 270 mg. What would be the expected mass of the
sample in the year 2011, to the nearest whole number?
Answers
Answer:
193 mg
Step-by-step explanation:
Exponential decay formula:
[tex]A_t = A_0e^r^t[/tex]where Aₜ = mass at time t, A₀ = mass at time 0, r = decay constant (rate), t = timeOur known variables are:
1998 to the year 2004 is a total of t = 6 years.The sample of radioactive isotope has an initial mass of A₀ = 360 mg at time 0 and a mass of Aₜ = 270 mg at time t.Let's solve for the decay constant of this sample.
[tex]270=360e^-^r^(^6^)[/tex][tex]270=360e^-^6^r[/tex] [tex]\frac{3}{4} =e^-^6^r[/tex][tex]\text{ln} (\frac{3}{4} )= \text{ln}(e^-^6^r)[/tex] [tex]\text{ln} (\frac{3}{4} )=-6r[/tex] [tex]r=-\frac{\text{ln}\frac{3}{4} }{6}[/tex] [tex]r=0.04794701[/tex]Using our new variables, we can now solve for Aₜ at t = 7 years, since we go from 2004 to 2011.
Our new initial mass is A₀ = 270 mg. We solved for the decay constant, r = 0.04794701.
[tex]A_t=270e^-^(^0^.^0^4^7^9^4^8^0^1^)^(^7^)[/tex] [tex]A_t=270e^-^0^.^3^3^5^6^2^9^0^7[/tex][tex]A_t=193.01982213[/tex]The expected mass of the sample in the year 2011 would be 193 mg.

∠ XNM and ∠ XKL are alternate angles and are congruent, then
∠ XNM = 35°
The sum of the 3 angles in a triangle = 180° , so
∠ XMN = 180° - (95 + 35)° = 180° - 130° = 50°

Answers
Answer:
20°
Step-by-step explanation:
Look at the attached photo.
∠a and ∠e are equal because they are vertical angles.
So, m∠a = 110°
Then, ∠f is an exterior angle to angles a and c. So,
m∠f = m∠a + m∠c
Substitute and solve.
130 = 110 + m∠c
m∠c = 20°
Then, ∠c and ∠d are vertical angles so they are equal.
m∠c = m∠d
m∠d = 20°

A store sells 24 greeting cards for $12. Select the three unit rates that describe this sale. CLEAR CHECK 2 cards per dollar $0.50 per card 10 cards per $5 $6 per dozen cards
Answers
Answer:
2 cards per dollar
$0.50 per card
$6 per dozen cards
Step-by-step explanation:
The unit rate of greeting if a store sells 24 greeting cards for $12 is $0.5, so option $0.50 per card is correct.
What is Unit rate?
Unit rate means the amount of rate for the unit quantity of some things, for example, if you buy 1 kg apple for $2 then the unit rate of apple is $2.
Given:
The selling price of 24 greetings =$12,
The unit rate, of a greeting, is = The selling price of 24 greetings / no of greetings
The unit rate = 12 / 24
The unit rate = $0.5
Therefore, the unit rate of greeting if a store sells 24 greeting cards for $12 is $0.5.

m∠ACB = 49.88°
Step-by-step explanation:
From the figure attached,
Measure of wire AC attached to the top 'C' of the building BC = 340 m
Horizontal distance between the base 'B' of the building and point A = 260 m
Angle of depression = ∠ACB
By applying sine rule in the given triangle,
sin(∠ACB) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AB}{BC}[/tex]
= [tex]\frac{260}{340}[/tex]
m∠ACB = [tex]\text{sin}^{-1}(764706)[/tex]

Production shows that only 3 of the first 10 phones are working which is 30% of the phones describe how the percentage other working phones changes if the 11th and 12th phone won't work correctly
Answers
Answer:
If you have 10 phones, this is the 100%
then:
10 = 100%
Now we know that only 3 of them work correctly, then the percentage of pones that works correctly can be related to:
3 = X%
To find the value of X%, we can take the quotient of the equations:
3 = X%
and
10 = 100%
We ge:
(3/10) = (X%/100%)
We solve this for X and we get:
(3/10)*100% = X% = 30%
As we already know.
Now let's see how this percentage changes if we add more phones that do not work correctly.
Now we add another phone that does not work, so we have a total of 11 phones and 3 of them work.
then:
3 = X%
11 = 100%
The quotient is:
(3/11) = (X%/100%)
(3/11)*100% = X% = 27.3%
If we add another phone, now we have 12 phones and only 3 of them works, then 12 is the 100%, and we have the equations:
3 = X%
12 = 100%
Then we get:
(3/12) = X%/100&
(3/12)*100% = X% = 25%

Determine whether each given pair of endpoints lies on the same horizontal or vertical line.
If so, find the length of the line segment that joins the pair of points.
If not, explain how you know the points are not on the same horizontal or vertical line.
(3,-8) and (3,-1)
Answers
Given:
The pair of end points: (3,-8) and (3,-1).
To find:
Whether the given pair of endpoints lies on the same horizontal or vertical line.
Solution:
If the x-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same vertical.
If the y-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same horizontal.
The given endpoints are (3,-8) and (3,-1).
From the given endpoints, it is clear that the x-coordinates of the endpoints are same. So, the given endpoints lies on the same vertical line.
The length of the line segment that joins the pair of points is
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]D=\sqrt{(3-3)^2+(-1-(-8))^2}[/tex]
[tex]D=\sqrt{(0)^2+(-1+8)^2}[/tex]
[tex]D=\sqrt{(7)^2}[/tex]
[tex]D=7[/tex]
Therefore, the given endpoints lies on the same vertical line and the length of the line segment is 7 units.

Answer:
f(n) = 2 × [tex]3^{n-1}[/tex]
Step-by-step explanation:
In order to write an explicit rule for a geometric function, you need to know the common ratio; you can find the common ratio by dividing two consecutive terms:
6 ÷ 2 = 3, 18 ÷ 6 = 3, 54 ÷ 18 = 3, etc..
Now you know the common ratio is 3. At this point you can write your explicit function following the rule f(n) = [1st term] × [common ratio]^(n-1):
f(n) = 2 × 3^(n-1)
