Answers
Solution
For this case we can find the area as the sum of the rectangle and the semicircle so we have this:
A1= 3in * 4in= 12 in^2
A2 = (pi/2) *(2in)^2 = 6.28 in^2
then the total area is:
A= A1+ A2= 12+ 6.28 in^2 = 18.28 in^2
And then the perimeter similarly we have:
P= 2*4 in + 2*3in + 2pi*(4in/2) = 8+ 6+ 12.56 in= 26.56in
Then the final answer is:
Area ~18.28 in^2 and Perimeter ~26.56 in

Given that,
We have to find an arithmetic polynomial that meets the requirements.
Q has zeros of degree 3 is -4 and 1+i.
There is a complex number is i.
When working with complex numbers, the following relationship is the most crucial:
i²=-1
A function's zeros:
This polynomial, given by f(x), has roots of x₁, x₂, x₃..... in which an is the leading coefficient and can be represented as a(x-x₁)(x-x₂)(x-x₃).....
Degree 3 and zeros -4 and i+1 make up Q.
Given that complex roots are always complex-conjugate, 1 - i is also a root if 1 + i is a root.
The leading coefficient, as we will mention, is 1.
Q(x)=(x-(-4))(x-(1-i))(x-(1+i))
Q(x)=x³+4x²-10x+12
Therefore, the polynomial we get is Q(x)=x³+4x²-10x+12.

It is stated in the problem that ΔGEO is congruent with ΔFUN. On the first triangle, the measurement of angle E and angle G is given but the measurement of angle O is not given. Using the congruence relation of the two triangles, it is true that
[tex]m\angle O\cong m\angle N[/tex]The measurement of angle N is provided in the problem, which is equal to 40 degrees. Hence, we can say that angle O has also an angle measurement of 40 degrees base on the statement above.
The sum of the interior angles of the triangle is equal to 180 degrees. This means that if we add up the interior angles of the triangle GEO, we have the following equation
[tex]m\angle G+m\angle E+m\angle O=180[/tex]Substitute the measurement of each angle on the equation above and compute, we get

Determine which set of side measurements could be used to form a triangle.
12, 23, 7
10, 7, 2
8, 3, 11
5, 11, 8
Answers
Answer:
Among the given, the set of side measurements (5, 11, 8) could be used to form a triangle.
Step-by-step explanation:
As we know,
For forming a triangle, "The sum of the length of any two sides of a triangle is greater than the length of the third side."
The side opposite the largest angle of a triangle is the largest side. Any exterior angle of the triangle is equal to the sum of its interior opposite angles.
Now taking the value given in the option:
We have the first set of values: 12, 23, 7
As here, let us assume that, a = 12, b = 23, c = 7
So, for the formation of triangle a + b > c
So, 12 + 7 = 19 < 23
Hence, this set of values can't form a triangle.
We have the second set of values: 10, 7, 2
As here, let us assume that, a = 7, b = 2, c = 10
So, for the formation of triangle a + b > c
So, 7 + 2 = 9 < 10
Hence, this set of values can't form a triangle.
We have the third set of values: 8, 3, 11
As here, let us assume that, a = 8, b = 3, c = 11
So, for the formation of triangle a + b > c
So, 8 + 3 = 11 < 11
Hence, this set of values can't form a triangle.
We have the fourth set of values: 5, 11, 8
As here, let us assume that, a = 5, b = 8, c = 11
So, for the formation of triangle a + b > c
So, 5 + 8 = 13 > 11
Hence, this set of values can form a triangle.

What is probability?The study of random events is the focus of the mathematical field known as probability theory. A random event's outcome can take any of a number of possible forms; it cannot be predicted before it happens. The outcome as it occurs is thought to have been determined by chance.
In everyday language, the word "probability" can mean a number of things. In order to develop and apply the mathematical theory of probability, two of these are particularly crucial. One is the interpretation of probabilities as relative frequencies; simple games involving coins, cards, dice, and roulette wheels serve as examples for this.
Assuming that the outcome of child born as a bopy or girl is 50% then each boy has a probability of 1/2
The odds of having all girls is = 1/2¹² = 1/4096 ≈ 0.000244
The odds of have at least 1 boy = 1 - 1/4096
= 0.999756

______ knots
Answers
The distance is changing at 153 nots at 5 P.M.
According to the Pythagoras Theorem, the square of the hypotenuse of a right angle triangle is equal to the sum of squares of the other two sides of the triangle. A derivative is suppose x and y are two variables, then the rate of change of x with respect to y is called a derivative. Differentiation is a process of finding the derivative of a function.
According to the question,
At noon, ship A is 50 nautical miles due west of ship B. (given)
Ship A is sailing west at 17 knots (given)
ship B is sailing north at 17 knots (given)
using the Pythagorean Theorem,
c^2 = a^2+b^2
Here, c is the distance between them at any point
a is the distance of ship A from initial point
b is the distance of ship B from initial point
Now,
initially ship A is due by 50 nautical miles (given)
and in 5 hours it travels 35*17 miles (given)
So, a = 50+5*17 = 50+85 = 135 nautical miles
Similarly b = 5*17 = 85 nautical miles
c^2 = 135^2+85^2 = 18225+7225
= 25450
c = √25450
c = 159.53 nautical miles
But we need to find how fast (in knots) is the distance between the ships changing
that is we need dC/dt (differentiation)
c^2 = a^2+b^2
Differentiating we get,
2cdc/dt = 2a*da/dt + 2b* db/dt
(the power comes on front during differentiating)
We now have da/dt = 17
db/dt = 17
So, dc/dt = (135*17+85*17)/(159.53) = 153 approx. knots
Therefore, we can conclude that the distance is changing at 153 nots at 5 P.M.

(If you're having trouble figuring out how to calculate time from speed and distance, just look at the units. Time (hr) is required as a result. We have two units: miles and miles per hour. Divided by mi/hr, mi is equal to mi * hr/mi, which equals hr. 28 / (vp + 2) is the time it takes to paddle 28 miles downstream. Also, these ought to be equal: 12 / (vp-2) = 28 / (vp+2) (cross multiplication) (cross-multiplication) 28 * (vp-2) = 12 * (vp+2) 28 vp - 56 = 12 vp + 24 (collect vp terms on one the left side and constants on the right side) (collect vp terms on one the left side and constants on the right side) (28-12) vp = 24 + 56\svp = 80/16
