The value of x = 8 in.
y = 8√2 = 11.31 in.
For the second question,
x = 8.3 units
Explanation
Isoscelles triangles have two of their sides being of the same lengths and those two sides are the ones whose base angles are the same.
From the image, we can see that two angles of the triangle have the same measures, hence, we can easily conclude that
x = 8 inches.
To find y, we will use pythagoras theorem.
The Pythagorean Theorem is used for right angled triangle, that is, triangles that have one of their angles equal to 90 degrees.
The side of the triangle that is directly opposite the right angle or 90 degrees is called the hypotenuse. It is normally the longest side of the right angle triangle.
The Pythagoras theorem thus states that the sum of the squares of each of the respective other sides of a right angled triangle is equal to the square of the hypotenuse. In mathematical terms, if the two other sides are a and b respectively,
a² + b² = (hyp)²
For this triangle,
hyp = y
a = 8 in
b = x = 8 in
a² + b² = (hyp)²
8² + 8² = y²
64 + 64 = y²
y² = 128
Take the square roots of both sides
√(y²) = √128
y = 8√2 = 11.31 in
For the other question.
In a right angle triangle, the side opposite the right angle is the Hypotenuse, the side opposite the given angle that is non-right angle is the Opposite and the remaining side is the Adjacent.
For that triangle,
Hyp = 11 units
Opp = ?
Adj = x
θ = 41°
We can then use trignometrical identities to solve this
CAH allows us to say
Cos 41° = (Adj/Hyp)
Cos 41° = (x/11)
x = 11 Cos 41°
x = 11 (0.7547)
x = 8.3 units

We have the equation of a quadratic function:
[tex]f(x)=(x-2)^2+2[/tex]And we need to find and plot the vertex of the equation.
We start by remembering that a quadratic equation is represented by a parabola and that the vertex is the point where the parabola changes direction, usually represented by (h, k) as shown in the following example:
• How do we find the vertex using the given equation?
We find it by comparing our equation with the general vertex form of the quadratic equation:
[tex]f(x)=a(x-h)^2+k[/tex]where
[tex](h,k)[/tex]is the vertex, and a is a constant.
Using the given equation, we find the h and k values:
[tex]\begin{gathered} f(x)=(x-2)^{2}+2 \\ \downarrow \\ h=2 \\ k=2 \end{gathered}[/tex]Therefore, the vertex is at (2, 2).

A rectangle is inscribed with its base on the -axis and its upper corners on the parabola y = 7 - x ^ 2 What are the dimensions of such a rectangle with the greatest possible area?
Answers
The width = 3.06
The height = 4.66
Explanation:The rectangle is inscribed with its base on the -axis and its upper corners on the parabola
Width = 2x
Height = 7 - x²
Area of the inscribed rectangle:
Area = width x height
A = 2x (7 - x²)
A = 14x - 2x³
Take the derivative of the area (A) and equate to zero
A' = 14 - 6x²
0 = 14 - 6x²
6x² = 14
x² = 14/6
x² = 2.33
x = √2.33
x = 1.53
The width = 2x
The width = 2(1.53)
The width = 3.06
Substitute x = 1.53 into the equation y = 7 - x² to solve for the height
y = 7 - 1.53²
y = 4.66
The height = 4.66

In the figure below, ∠APE and ∠EPD are congruent. What is the arc measure of major arc BAD on circle P in degrees?
Answers
You need to determine the measure of the arc BAD in the given circle P.
The angle measure of angle ∠BPD with the vertex in the center of the circle P is congruent to the measure of the intercepted arc BAD.
This means that to determine the measure of the arc, you need to determine the measure of the angle.
The measure of ∠BPD is equal to the sum of the measures of the adjacent angles that form it:
[tex]\angle\text{BPD}=\angle\text{BPA}+\angle\text{APE}+\angle\text{EPD}[/tex]∠APE and ∠EPD have an unknown measure but we know that they are equal, and we know that the total angle of a circle is 360º, i.e. the sum of all the angles is 360º
Let "x" represent the measure of angles ∠APE and ∠EPD, we can represent the total angle of the circle as follows:
[tex]360º=\angle\text{APE}+\angle\text{EPD}+\angle\text{DPC}+\angle\text{CPB}+\angle\text{BPA}[/tex]We know that
∠APE=∠EPD=x
∠DPC=42º
∠CPB=74º
∠BPA=136º
[tex]\begin{gathered} 360º=x+x+42+74+136 \\ 360=2x+252 \\ 360-252=2x \\ 2x=108 \\ \frac{2x}{2}=\frac{180}{2} \\ x=54º \end{gathered}[/tex]So ∠APE=∠EPD=54º
Now that we know the measure of these angles we can calculate the measure of ∠BPD
[tex]\begin{gathered} \angle\text{BPD}=\angle\text{BPA}+\angle\text{APE}+\angle\text{EPD} \\ \angle\text{BPD}=136+54+54 \\ \angle\text{BPD}=244º \end{gathered}[/tex]∠BPD=244º and, as mentioned before the measure of the intercepted arc is the same as the measure of the central angle, then its intercepted arc BAD = 244º as well.

Find the probability that overbooking occurs find the probability that the flight has empty seats
Answers
Answer:
P(Overbooking) = 0.0898
P(Empty seats) = 0.7461
Explanation:
The probability that overbooking occurs is the probability that arrives more than 6 passengers from the 9 that remain.
This probability can be calculated as:
[tex]P(x)=\frac{n!}{x!(n-x)!}\cdot p^x\cdot(1-p)^{n-x}[/tex]Where n is the total number of remaining passengers, and p is the probability that a passenger will arrive for the flight. So, the probability that x people arrive is:
[tex]P(x)=\frac{9!}{x!(9-x)!}\cdot0.5^x\cdot(1-0.5)^{9-x}[/tex]So, the probability that arrives 7, 8, or 9 people is:
[tex]\begin{gathered} P(7)=\frac{9!}{7!(9-7)!}\cdot0.5^7\cdot(1-0.5)^{9-7}=0.0703 \\ P(8)=\frac{9!}{8!(9-8)!}\cdot0.5^8\cdot(1-0.5)^{9-8}=0.0176 \\ P(9)=\frac{9!}{9!(9-9)!}\cdot0.5^9\cdot(1-0.5)^{9-9}=0.002 \end{gathered}[/tex]Therefore, the probability that overbooking occurs is:
[tex]\begin{gathered} P(\text{Overbooking)}=P(7)+P(8)+P(9) \\ P(\text{Overbooking)}=0.0898 \end{gathered}[/tex]On the other hand, the probability that the flight has empty seats is the probability that arrives fewer than 6 people for the flight.
So, using the same equation for P(x), we get that the probability that the flight has empty sats is:
[tex]\begin{gathered} P(\text{Empty seats)=P(0) +P(1) + P(2) + P(3) +P(4) + P(5)} \\ P(\text{Empty seats) = 0.7461} \end{gathered}[/tex]Therefore, the answers are:
P(Overbooking) = 0.0898
P(Empty seats) = 0.7461

Here, we want to graph the given inequality
To do this, we need to get the intercepts of the normal line with the inequality replaced by an equality sign
Thus, we have;
[tex]y\text{ = }\frac{2}{3}x-1[/tex]Generally, we have the equation of a linear graph as;
[tex]y\text{ = mx + b}[/tex]where m represents the slope and b represents the y-intercept
With respect to this question, -1 is y-intercept of the line
Thus, the point of the y-intercept is (0,-1)
Now, we proceed to get the x-intercept.
To do this, we simply substitute the value 0 for y
We have;
[tex]\begin{gathered} 0\text{ = }\frac{2}{3}x\text{ - 1} \\ \\ \frac{2x}{3}\text{ = 1} \\ \\ 2x\text{ =3 } \\ \\ x\text{ = }\frac{3}{2} \\ \\ x\text{ = 1.5} \end{gathered}[/tex]The x-intercept here is thus the point (1.5,0)
Normally, to plot the graph of the line, we simply connect the two intercepts with a straight line
In the case of this inequality too, we are going to join the two points, but this time with dots and not straight lines
And also, since the inequality is greater than, we are simply going to shade the side above the dotted line
Kindly note that if there was an inequality sign, wherein, we have greater than or equal to, we are going to join with a thick line and shade
Let us check what we have in the plot below;

Apply proportion
16/1=x/25
solve for x
x=16*25
x=400 miles
answer is 400 milesThe width of a rectangle measures (3u - 4v) centimeters, and its length measures
(10u + 2v) centimeters. Which expression represents the perimeter, in centimeters,
of the rectangle
Answers
Answer:
Step-by-step explanation:
Ok lets get rolling
So far as we know, perimeter is the sum of all sides of a figure
in a rectangle opposite sides are equal, therefore we after some machinations we get this equation
P of rectangle = 2(10u+2v) + 2(3u-4v)
P of rectangle = 20u+4v + 6u - 8v
P of rectangle = 26u - 4v
and thats ur answer
hope this helps

bags less than 3/8
[tex]\begin{gathered} \frac{1}{4}\longrightarrow2 \\ \\ \frac{1}{8}\longrightarrow1 \end{gathered}[/tex]are 3
to fin the total pounds we multiply each weight by the number of bags
[tex]\begin{gathered} \frac{1}{4}\times2=\frac{1}{2} \\ \\ \frac{1}{8}\times1=\frac{1}{8} \end{gathered}[/tex]now sum
[tex]\begin{gathered} \frac{1}{2}+\frac{1}{8} \\ \\ \frac{(8\times1)+(2\times1)}{8\times2} \\ \\ \frac{8+2}{16} \\ \\ \frac{10}{16}=\frac{5}{8} \end{gathered}[/tex]total weight is 5/8pounds
