Answer:
Solution
=2±√3
Explanation:
The solution of the given equation x² - 4x + 1 = 0 is;
x = 2 ± √3
We are given;
x² - 4x + 1 = 0
Using quadratic formula we have;
x = [-b ± √b² - 4ac]/2a
where;
a = 1
b = -4
c = 1
Thus;
x = [-(-4) ± √((-4)² - 4(1 * 1)]/2(1)
x = (4 ± √(16 - 4))/2
x = (4 ± √12)/2
x = (4 ± 2√3)/2
x = 2 ± √3

Evaluate the line integral by the two following methods. Xy dx + x2y3 dy c is counterclockwise around the triangle with vertices (0, 0), (1, 0), and (1, 4).
Not sure what "two methods" you refer to, so I'll assume you're supposed to compute the line integral directly as well as with Green's theorem.
Direct computation:
It looks like the line integral is
[tex]\displaystyle \int_C xy \, dx + x^2y^3 \, dy[/tex]
where C is the union of three line segment. We'll partition C and parameterize each component by
• C₁, the line segment from (0, 0) to (1, 0) : x(t) = t and y(t) = 0;
• C₂, from (1, 0) to (1, 4) : x(t) = 1 and y(t) = 4t;
• C₃, from (1, 4) to (0, 0) : x(t) = 1 - t and y(t) = 4 - 4t;
each with 0 ≤ t ≤ 1.
Compute the integrals over each component:
• Along C₁, we have y = 0, so this integral contributes nothing.
• Along C₂,
[tex]\displaystyle \int_0^1 4t \cdot 0 \, dt + (4t)^3 \cdot 4 \, dt = 256 \int_0^1 t^3 \, dt = 64[/tex]
• Along C₃,
[tex]\displaystyle \int_0^1 (1-t)(4-4t) \cdot (-dt) + (1-t)^2(4-4t)^3 \cdot (-4\, dt) \\\\ = \int_0^1 \left(-260 + 1288 t - 2564 t^2 + 2560 t^3 - 1280 t^4 + 256 t^5 \right) \, dt = -44[/tex]
So, the total line integral is
[tex]\displaystyle \int_C xy \, dx + x^2y^3 \, dy = 0 + 64 - 44 = \boxed{20}[/tex]
Using Green's theorem:
The interior of C is the triangular region
[tex]D = \{(x, y) : 0 \le x \le 1 \text{ and } 0 \le y \le 4x\}[/tex]
and the integrand has no singularities either on C or within D. So by Green's theorem,
[tex]\displaystyle \int_C xy \, dx + x^2y^3 \, dy = \iint_D \frac{\partial(x^2y^3)}{\partial x} - \frac{\partial(xy)}{\partial y} \, dx \, dy = \int_0^1 \int_0^{4x} (2xy^3 - x) \, dy \, dx[/tex]
The remaining integral is trivial.
[tex]\displaystyle \int_0^1 \int_0^{4x} (2xy^3 - x) \, dy \, dx = \int_0^1 x \int_0^{4x} (2y^3 - 1) \, dy \, dx[/tex]
[tex]\displaystyle \int_0^1 \int_0^{4x} (2xy^3 - x) \, dy \, dx = \int_0^1 x \left(\frac12 (4x)^4 - 4x\right) \, dx[/tex]
[tex]\displaystyle \int_0^1 \int_0^{4x} (2xy^3 - x) \, dy \, dx = \int_0^1 \left(128x^5 - 4x^2\right) \, dx[/tex]
[tex]\displaystyle \int_0^1 \int_0^{4x} (2xy^3 - x) \, dy \, dx = \frac{64}3 - \frac43 = \boxed{20}[/tex]

A desert is very hot during the day and receives very little rain. Which plants will likely survive in this kind of environment?.
Explanation:
A cactus is a plant that would survive
A desert is very hot during the day and receives very little rain. The plants that will likely survive in this kind of environment are plants with waxy coatings. Thus the correct option is A.
What is the environment?The environment is referred to as the surroundings where all living and nonliving things are present. The environment contains different types which include the atmosphere, hydrosphere, lithosphere, and biosphere.
Desert is referred as dryland which constitutes more than one-fifth of the planet's landmass and can be found on every continent. These regions experience a "moisture imbalance," which indicates that they typically lose more moisture to drainage.
The gravity of the waxy substance on their leaves, floating plants, which have short branches, would sink underwater if not for the weight of the leaves. The plant is shielded from hazards outside by the waxy layer, which also holds moisture.
Therefore, option A is appropriate.
