The value of X is 1

Step-by-step explanation:

Trust me i did this already.

Answer:

x=3

Step-by-step explanation:

we can use the  pythagora thearom as it is a right angled triangle.

[tex]a^{2} +b^{2} =c^{2}[/tex]

so in this example it would be like this

[tex]x^{2} +x^{2} =(3\sqrt{2})^{2}[/tex]

so lets simplify it to this

[tex]2x^{2} =18[/tex]

now all thats left is to get x on its own

[tex]x^{2} =9[/tex]

[tex]x=+or-3[/tex]

x cant be -3 so x =3

Answer:

Step-by-step explanation:

It cannot be decided from the information given as we have only been given the side lengths of each of the squares.  We have not been told at what point along each side length the other square intersects, nor have we been told the angle at which the squares intersect each other.   We would need this information to be able to calculate the specified area.

Answer :

⠀

Explanation :

We know that,

⠀

Therefore,

[tex]{ \longrightarrow \sf \qquad \angle1 + \angle2 + \angle3= 180 {}^{ \circ} }[/tex]

[tex]{ \longrightarrow \sf \qquad 50 {}^{ \circ} + 58{}^{ \circ}+\angle3= 180 {}^{ \circ} }[/tex]

[tex]{ \longrightarrow \sf \qquad 108{}^{ \circ}+\angle3= 180 {}^{ \circ} }[/tex]

⠀

Subracting 108° from both sides :

[tex]{ \longrightarrow \sf \qquad 108{}^{ \circ} - 108 {}^{ \circ} +\angle3= 180 {}^{ \circ} - 108 {}^{ \circ} }[/tex]

[tex]{ \longrightarrow \pmb{\bf \qquad \angle3= 72 {}^{ \circ} }}[/tex]

⠀

Therefore,

The base and height of the triangle is 16 meters and 7 meters respectively.

Scalene triangles are triangles which has all three sides having different side lengths and the measure of all the three angles is different.

Given that,

Area of a scalene triangle = 56 square meter

Base of the triangle = 2x - 6 meters

Height of the triangle = x - 4 meters

The formula to find the area of a triangle is,

Area = [tex]\frac{1}{2}[/tex] × base × height

Substituting,

[tex]\frac{1}{2}[/tex] × (2x - 6) (x - 4) = 56

[tex]\frac{1}{2}[/tex] (2x² - 6x - 8x + 24) = 56

[tex]\frac{1}{2}[/tex] (2x² - 14x + 24) = 56

x² - 7x + 12 = 56

x² - 7x - 44 = 0

Factoring,

(x - 11) (x + 4) = 0

So, x = 11 or x = -4.

x = -4 is not possible, since the negative lengths are not possible.

So, x = 11

So base = 2x - 6 = 16 and height = x - 4 = 7

Hence the base and height are 16 and 7 respectively.

Answer:  approximately 7525 feet

A more accurate value is 7,524.6679636332 feet, but even that isn't fully exact.

==========================================================

Explanation:

The change in height, or delta height value, is 11200-9000 = 2200 which is the vertical component of the right triangle shown below. This side is opposite the reference angle, aka the angle of elevation 17°

The hypotenuse is x, which is the length of the trail. Assume we're dealing with a flat and straight surface. Of course realistically the ground is very likely going to be bumpy with various curved complexities; but we'll simplify things greatly.

We'll use the sine ratio to find x.

sin(angle) = opposite/hypotenuse

sin(17) = 2200/x

x*sin(17) = 2200

x = 2200/sin(17)

x = 7,524.6679636332

Assuming your teacher wants you to round to the nearest whole number, then we'd get to 7525 feet

We need Hypotenuse

[tex]\\ \rm\rightarrowtail sin\theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\\ \rm\rightarrowtail sin17=dfrac{2200}{h}[/tex]

[tex]\\ \rm\rightarrowtail h=2200/sin17[/tex]

[tex]\\ \rm\rightarrowtail h=2200/0.2923[/tex]

Answer:

(x, y) ==> (-4, -3)

Step-by-step explanation:

-2(3x + y = -15) ==> -6x - 2y = 30

3x + 2y = -18

-6x - 2y = 30

3x + 2y = -18

-3x = 12

/-3    /-3

x = -4

Now, we solve for y:

-6x - 2y = 30

-6(-4) - 2y = 30

24 - 2y = 30

-24        -24

-2y = 6

/-2    /-3

y = -3

(x, y) ==> (-4, -3)

our powers are 3,3,1 (because no exponent means to the power of 1)

Adding the powers is 7

so u⁷

Answer:

it can be simplified to Y^(-5)X^(-2)

Step-by-step explanation:

So the exponents can be added because the terms are all being multiplied:

For Y: (-8)+(3)=(-5)

For X: (0)+(-2)=(-2)

So the simplified answer is Y^(-5)X^(-2)

That is also the same as 1/[(x^5)(y^2)]

[tex]y''+4y'+4y=0,\:y(0)=1,\:y'(0)=1\\\\m^2+4m+4=0\\\\(m+2)(m+2)=0\\\\m=-2[/tex]

Thus, since we have equal real roots, we use the general solution [tex]y(x)=C_1e^{m_1x}+C_2e^{m_1x}[/tex] and our initial conditions to set up our system of equations:

[tex]y(x)=C_1e^{-2x}+C_2e^{-2x}\\\\y(0)=C_1e^{-2(0)}+C_2e^{-2(0)}\\\\1=C_1+C_2[/tex] <-- First one

Solve the system

[tex]C_1+C_2=-2C_1-2C_2\\\\3C_1+3C_2=0\\\\3C_1=-3C_2\\\\C_1=-C_2[/tex]

[tex]1=C_1+C_2\\\\1=-C_2+C_2\\\\1=0[/tex]

Therefore, there are no solutions to the differential equation given the initial conditions.

Answer:

See explanation below.

Step-by-step explanation:

First I'm going to find angle 2. Angle two plus 55 is equal to 115. 180-115=65. 65-55=10 Angle 2 = 10

Next, we can find angle 3. 55+10=65. 180-65=115. Angle 3 = 115

Angle 2 is equal to angle 5, angle 3 is equal to angle 6, and angle 4 is equal to 55.

Angle 5 = 10

Angle 4 = 55

Angle 6 = 115

Now we can find angle 8. 180-115=65. Angle 8 = 65

Angle 11 = 65

Angle 12 = 115

10+115=125 Angle 10 = 125

180-125 = 55 Angle 9 = 55

Angle 14 = 55

Angle 13 = 125

Answer:

<8, <5, <10 are 65 degrese

Step-by-step explanation:

oki, so, 55+m<2 must be 115 because 115 is a corresponding angel to 55+<2 meaning they are =, so m<2=115-55, m<2=60.

m<3 must then = 65 because line a phase a 180 angle (assuming a and b are parallel)

<3 is also corresponding to angle <10 so by the transitive property m<10=65.

m<8 must then = 65 because the angle of line b in 180, and the transversal cuts 115, 180-115=65.

whoops, then finally 5 is vertical from <2 so it is congruent, so <2 must be 65, so all angles are 65 degrees.

Answer:

Slope m = [tex]\frac{5}{8}[/tex]

Step-by-step explanation:

[tex]x_{1}=-6\\ y_{1}=-4\\\\x_{2}=2\\y_{2}=1\\\\[/tex]

def. of slope = rise over run

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{2}}[/tex]

so:

[tex]\frac{1-(-4)}{2-(-6)} = \frac{1+4}{2+6} = \frac{5}{8}[/tex]

We get [tex]\frac{5}{8}[/tex] as our slope

The slope of the line in the graph is 5/8.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

As we observe the graph the line is passing from points (-6, -4) and (2, 1)

Slope = 1+4/2+6

=5/8

Hence, the slope of the line in the graph is 5/8.

Answer:

Step-by-step explanation:

Use the compounded interest formula:

[tex]A = P(1+\frac{r}{n})^{nt}[/tex]

In our case,

P = 3000

r = 8% = 0.08

n = 12 (months per year)

t = 18 (years in total)

Therefore, A ≈ $12601.72 (2.d.p.)

Suppose ABC be a triangle such that ∠A = 4x + 7 ,

∠B = 3x + 5 & ∠C = 6x + 12

We know, the sum of interior angles of a Triangle is 180°, therefore, ∠A + ∠B + ∠C = 180°

or, 4x + 7 + 3x + 5 + 6x + 12= 180°

or, 13x = 180 - 24

or, x = 156/ 13 = 12

As per the given data, the resulting expression after factoring by grouping is [tex](x^2 + 7)(x - 4)[/tex], which is option A.

Factoring is the process of finding the factors of an algebraic expression, which involves writing the expression as a product of simpler expressions.

There are different methods for factoring, depending on the type of expression. Some common methods include: Factoring by grouping, Factoring quadratics, and Factoring higher degree polynomials.

We can factor [tex]x^3 - 4x^2 + 7x - 28[/tex] by grouping the first two terms and the last two terms as follows:

[tex]x^3 - 4x^2 + 7x - 28= (x^3 - 4x^2) + (7x - 28)\\= x^2(x - 4) + 7(x - 4)\\= (x^2 + 7)(x - 4)[/tex]

Therefore, the resulting expression after factoring by grouping is (x^2 + 7)(x - 4), which is option A.
