A complex number is represented on a complex plane. The number [tex]z = 3-5i[/tex] is represented in a smilar manner as real numbers but y axis cosidered a imaginary axis.
What is a complex plane?
A complex plane is formed by complex numbers in a similar manner as the Cartesian coordinate system. But the x axis is made up of real numbers and y axis is made up of imaginary numbers.
A complex number is plotted on a complex plane. In the complex plane the x axis is known as the real axis and the y axis is known as the imaginary axis.
Consider the given complex number.
[tex]z = 3-5i[/tex]
Here, 3 is real number and -5 is imaginary number.
Since 3 is real number hence, move 3 steps in the right direction on x axis. Now, -5 is the imaginary number hence, move 5 steps in the downward direction parallel to the y axis.
The final position is [tex]z = 3-5i[/tex].

What is a reflection?In Geometry, a reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.
What is a reflection across the x-axis?In Mathematics, a reflection across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would change from positive to negative. Therefore, a reflection across the x-axis is given by this transformation rule: (x, y) → (x, -y).
By applying a reflection across the x-axis to the function, we have;
f(x) = 2|x|
g(x) = -f(x)
g(x) = -(2|x|)

Answers
The evidence is not sufficient to support the claim since the p-value is 0.1833 higher than 0.05, so e) none of the preceding.
How to find p-value?α = significance level = 0.05
n = sample size
df = degree of freedom = n - 1 = 10 - 1 = 9
Before we find the p-value, we use t test formula. But, before that we calculate mean and standard deviation for two population with excel.
In excel we get,
[tex]\bar x_1[/tex] = 231.8
[tex]\bar x_2[/tex] = 214.8
[tex]\sigma_1[/tex] = 41.95
[tex]\sigma_2[/tex] = 37.90
Next, we can calculate t test. So,
t = [tex]\frac{\bar x_1 -\bar x_2}{\sqrt{\frac{\sigma^2_1+\sigma^2_2}{n}}}[/tex]
= [tex]\frac{231.8-214.8}{\sqrt{\frac{41.95^2+37.9^2}{10}}}[/tex]
= [tex]\frac{17}{\sqrt\frac{3,196.2125}{10}}[/tex]
= 0.9509
Using t score to p-value calculator for 0.9509, we get p-value = 0.1833.
Thus, the p-value is 0.1833 is higher than significance level 0.05 so there is no sufficient evidence to support the claim.

Answers
Answer:
Step-by-step explanation:
1.Φ(u,v) gives the parametrization with its x, y, and z components. So, x=7u+4, y=u-v, and z=13u+v. We can use this to get the tangent vectors by taking the respective partial derivatives. Tu=<7, 1, 13> by taking the u derivatives of the components and Tv=<0, -1, 1> by taking the v derivatives of the components.
2. Taking the cross product of Tu and Tv will give the normal vector n(u,v), which is <14, -7, -7>
3. To find Area(S), you have to multiply the area of D by the magnitude of the normal vector from the previous step. D is the region defined by 0<=u<=5 and 0<=v<=6, so the area of D is 5*6=30. Multiply this by the magnitude of the normal vector to find that Area(S)=30sqrt(294)
4. To integrate, we first must put the initial function in terms of the parameters we found in the first step. Replace y with u-v and z with 13u+v. Next, multiply this integrand by the magnitude of the normal vector (sqrt294) and apply the given bounds for u (0<=u<=5) and v (0<=v<=6). From here the problem can be integrated like any other double integral, the final answer being 190sqrt(294)

a right triangle has a hypotenuse of length 3 units and one side of length 2 units. what is the area of the triangle?
Answers
The area of the triangle is 3 units² which has a hypotenuse of 3 units and a side of 2 units.
What is a triangle?A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon.
There are three sides and three angles in every triangle, some of which may be the same.
In the case of a right triangle, the three sides are given unique names: the hypotenuse, which is the side that faces the right angle, and the legs, which are the other two sides.
Every triangle is bicentric and convex.
The triangle's interior is the area of the plane it encloses; the outside is the rest of the plane.
So, the area of the triangle will be:
We know that the hypotenuse is 3 units.
The length of the other side is 2 units.
Area of triangle formula: 1/2 * base * height
Now, insert values in the formula and calculate:
1/2 * base * height
1/2 * 2 * 3
3 units²
Therefore, the area of the triangle is 3units² which has a hypotenuse of 3 units and a side of 2 units.

Hilary paints a wall in her bedroom that has two windows, as shown. What percent of the wall does she paint? Round your answer to the nearest whole percent, it necessary.
Answers
The percent of the wall does she paint will be;
⇒ 79%
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The length of room wall = 8 feet
The width of room wall = 12 feet
The length of windows = 5 feet
The width of windows = 2 feet
Now,
The area of wall = 12 x 8 feet²
= 96 feet²
And, The area of windows = 5 x 2 feet²
= 10 feet²
Hence, The area of paints a wall in her bedroom = 96 - 2 (10)
= 96 - 20
= 76 feet²
So, She paint the wall of area 76 feet².
Since, The area of whole wall = 96 feet²
But, There are two window.
So, The percent of only wall paint of are 76 feet² = 100 x 76 / 96
= 79.16%
