find the length and the midpoind of the segment with the given endpointsA(2,3 )and B(5,7)
Answer:
[tex]Suppose,~a~line~segment~has~midpoints~(x_1,y_1)~and~(x_2,y_2). Then,\\Midpoint~of~the~line = (\frac{x_2+x_1}{2},\frac{y_2+y_1}{2})\\Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\According~ to~ the ~question,\\(x_1,y_1) = A(2,3)\\(x_2,y_2) = B(5,7)\\Midpoint~of~AB = (\frac{2+5}{2},\frac{3+7}{2}) = (\frac{7}{2},5)\\AB = \sqrt{(5-2)^2+(7-3)^2} = \sqrt{3^2+4^2} = 5units[/tex]

Step-by-step explanation:
Answer for the first question.
since the triangles are congruent so angles and sides are also congruent I.e. sides and angles are equal then,
3x - 3 = 12
3x = 12 + 3
3x = 15
x = 5
55° = 7x + y
55° = 7 * 5 + y
35° + y = 55°
y = 55° - 35°
y = 20°
Answer for the second question,
x + 70° = 2x - 2° {Exterior angle of a triangle is equal to the sum of two opposite interior angles }
2x - x = 70° + 2°
x = 72°
Now
<WXY = 2x - 2°
= 2 * 72° - 2
= 142 °

(1 point) An innovative rural public health program is reducing infant mortality in a certain West African country. Pretend the program in Senegal has been reducing infant mortality at a rate 7.3 % per year. How long will it take for infant mortality to be reduced by 33 %
Answer:
Infant mortality will reduce to 33% in 1.63 years
Step-by-step explanation:
Let the population be X
Population after 1 year
[tex]X - 7.3[/tex] % of [tex]X[/tex]
[tex]X -0.073 X\\0.927X[/tex]
As we know
[tex]P = P_0 * e^{rt}[/tex]
Substituting the given values we get -
[tex]\frac{P_0 - 0.33P_0}{P_0} = e^{-0.33 * t}\\0.67 = e^{-0.33 * t}\\[/tex]
Taking log on both sides we get -
[tex]-0.20273 = -0.33 * t\\t = 1.627[/tex]
You can form a general expression for resultant reduction percentage after t years. Then equate it with 33% to get the value of t
The time that will be taken by the program to reduce the infant mortality rate by 33% is approx 3.35 years.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
How to find a general expression for resultant reduction percentage after t years?The rate of decrement for infant mortality rate is 7.3% per year.
Let the mortality rate in the start be [tex]r[/tex]
Then after 1 year it becomes
[tex]r - \dfrac{r}{100} \times 7.5 = r(1-\frac{7.5}{100}) = r_1 \text{\: (say)}[/tex]
After 1 more year, we will have:
[tex]r_1 -> r_1(1 - \frac{7.5}{100}) = r(1-\frac{7.5}{100})(1-\frac{7.5}{100}) = r(1-\frac{7.5}{100}) ^2 = r_2 \text{\: (say)}[/tex]
Thus, after t years, we will have:
[tex]r_t = r(1-\frac{7.5}{100})^t[/tex]
Simplifying it, we get:
[tex]r_t = r(1 - 0.075)^t = r(0.925)^t[/tex]
The percent of decrement can be calculated by:
[tex]p = \dfrac{\text{old rate - new rate}}{\text{old rate}} \times 100[/tex]
Thus,
the percent of decrement after t years will be
[tex]p = \dfrac{r - r_t}{r} \times 100 = \dfrac{r(1- (0.925)^t)}{r} \times 100 = 100(1-0.925^t)\\\\p = 100(1-0.925^t)[/tex]
We need the time after which the infant mortality rate would be reduced by 33%, thus, p = 33%
or
[tex]p = 33\\p = 100(1-0.925^t) = 33\\1 -0.925^t = \dfrac{33}{100}\\t = log_{0.925}(1 - \dfrac{33}{100}) \approx 3.3525[/tex]
Thus, after approx 3.35 years, the mortality rate would decrease by 33%
Thus,
The time that will be taken by the program to reduce the infant mortality rate by 33% is approx 3.35 years.

find the sum of the 2 terms of an A P are in the ratio of (2n-1):(2n+1) then find the ratio of their 10th term
Answer:
37/39
Step-by-step explanation:
We know that formula for n terms of an AP is written as;
(n/2)(2a + (n - 1)d)
Let the sum of the first AP be;
(n/2)(2a + (n - 1)d)
Let the sum of the second AP be (n/2)(2A + (n - 1)D)
We are told that they have a ratio of (2n-1):(2n+1)
Thus;
(2n-1)/(2n+1) = [(n/2)(2a + (n - 1)d)]/[ (n/2)(2A + (n - 1)D)]
On RHS, n/2 will cancel out to give;
(2n-1)/(2n+1) = [(2a + (n - 1)d)]/[(2A + (n - 1)D)]
Rewriting this we have;
(2n - 1)/(2n + 1) = [(a + ½(n - 1)d)]/[A + ½(n - 1)D)]
But we want tod find;
(a + (n - 1)d)/(A + (n - 1)D)
Thus,at n = 10, we have;
(a + 9d)/(A + 9D)
Comparing with [(a + ½(n - 1)d)]/[A + ½(n - 1)D)], we can say that;
½(n - 1) = 9
n = 18 + 1
n = 19
Thus;
(a + 9d)/(A + 9D) = (2n-1)/(2n+1)
Putting n = 19 gives;
(a + 9d)/(A + 9D) = (2(19) - 1)/(2(19) + 1)
(a + 9d)/(A + 9D) = 37/39

The ratio of pharmacy technicians on duty at the hospital during for the day vs. night shifts is 32:19. 1. Express as a percentage how many pharmacy technician staff work the night shift. Round your final answer as a percentage rounded to two decimal places. Explain the answer
Answer:
37.38
Step-by-step explanation:
Remark
The ratio tells you how they are divided between night and day.
In other words night/ day = 19/32
That's not what you want.
What you want is night over total.
Total
Total = night + day = 19.1 + 32 = 51.1
Night Percent
Night% = Night * 100 / Total
Night% = 19.1 * 100 / 32
Night% = 37.38 %
Here, we are required to express ratio as a percentage
The percentage of pharmacy technician during the night is 37.25%
pharmacy technician during the day = 32
pharmacy technician during the night = 19
Total ratio = 32 + 19
= 51
percentage of pharmacy technician during the night = pharmacy technician during the night / Total ratio × 100
= [tex] \frac{19}{51} \times 100[/tex]
= 0.3725490196078 × 100
= 37.254901960784%
Approximately
37.25% to two decimal place
This means 37.25% of pharmacy technician work during the night
