given parallelogram ABCD solve for x

The value of x is 18.8m

Given:

θ = 48°

Y = 17m

The law of tangent which is also called as tangent formula or tangent rule is the ratio of the sine of the angle to the cos of the angle.

tan θ = Opposite / Adjacent.

Here,

Sum of triangle = 180°

90° + 48° + x° = 180°

x° = 42°

tan θ = opposite/ adjacent.

Substituting the values

tan 42° = 17/x  (∴tan 42° = 0.9004)

0.9004 = 17/x

So we get,

x = 17/0.9004

x = 18,8m

Therefore, the value of x is 18.8m.

The area of the triangle is 8 unit².

The amount of space a shape takes up is called the area of that space.

Here,

The given vertices are

A= (-4,1)

B= (-7,5)

C= (0,1)

Now, as we know the x and y coordinates of three vertices of triangle.

So, we will use the coordinate geometry formula.

The general formula of the area of triangle is

If the triangle have a vertices (Ax,Ay ),(Bx,By ) and (Cx,Cy ) then the area is

Area=1/2×|Ax (By-Cy )+Bx (Cy-Ay )+Cx (Ay-By )|

Now, we will put the given coordinates values in above equation

Then we will get

Area=(1/2)×|(-4)(5-1)+(-7)(1-1)+0(1-5)|

Area=(1/2)×|(-4)(4)+(-7)(0)+0(-4)|

Area=(1/2)×|-16|

Remove the mode bracket.

Area=1/2×16

Area=8

Thus, the area of the triangle is 8 unit².

The triangle with sides length of  35 km , 83 km and 86 km cannot form a right triangle.

A right triangle is a triangle that has one angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

The sides of a triangle can be found using Pythagoras's theorem. Right triangle obeys  Pythagoras's theorem.

The  Pythagoras's theorem can be represented as follows:

c² = a² + b²

where

The hypotenuse is the longest side of the right triangle.

Hence, let's check if the side length of 35 km 83 km 86 km is a right triangle.

35² + 83² = 86²

1225 + 6889  ≠ 7396

The rocket reaches its maximum height at 2.25 second(s) after launch

The maximum height reached by the object is 88 feet.

The function is given as

h(t) = -16t² + 72t + 7

Differentiate the above function

So, we have the following representation

h'(t) = -32t + 72

Set to 0

-32t + 72 = 0

So, we have

32t = 72

Divide by 32

t = 2.25

Hence, the time is 2.25 seconds

In (a), we have

t = 2.25

Substitute t = 2.25 in h(t) = -16t² + 72t + 7

h(2.25) = -16(2.25)² + 72(2.25) + 7

Evaluate

h(2.25) = 88

The expression y = 4.998 · [tex]e^{1.098\cdot x}[/tex] is the exponential function that passes through the points (- 1, 5 / 3) and (3, 135).

Herein we find the location of two points set on Cartesian plane that belongs to an exponential function of the form:

[tex]y = A \cdot e^{B \cdot x}[/tex]

Where:

Which is equivalent to the following logarithmic expression:

㏑ y = ㏑ A + B · x

If we know that (x₁, y₁) = (- 1, 5 / 3) and (x₂, y₂) = (3, 135), then the following system of equations is generated:

㏑ (5 / 3) = ㏑ A - B

㏑ 135 = ln A + 3 · B

Then, we solve the system by numerical methods:

㏑ A = 1.609 (A = 4.998), B = 1.098

The value of s in the point (s,-3) after using slope formula is -4.

What is slope?

Slope is a term used to define how steep a line is. The rise of a line over the run of a line, or the change in the vertical direction (y) over the change in the horizontal direction, is the definition of slope (x). The slope is the angle at which one is moving forward or backward when skiing down a hill or climbing a mountain. Depending on what it is, the slope may occasionally be fairly flat or extremely steep. The slope of an object indicates how steep it is. Slope knowledge is crucial for daily decision-making. 

Using slope formula,

=> slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Now the given point  is ,

[tex](x_1,y_1)=(s,-3) \\(x_2,y_2)=(-8,-4)[/tex]

=> slope m= 1/4

=> [tex]\frac{1}{4}= \frac{-4+3}{-8-s}[/tex]

=> [tex]\frac{1}{4} = \frac{-1}{-8-s}[/tex]

=> -8-s=-4

=>-s=-4+8

=> -s=4

=> s =-4.

1) The yearly depreciation expense under the straight-line method is $2,000.

2) If the car was bought on April 3, the depreciation expense for the first year is approximately $1,500.

Under the straight-line depreciation method, the depreciation expense is the quotient of the depreciable amount (cost - residual value) divided by the estimated useful life of the asset.

The depreciation expense is prorated if it does not cover the full year.

Cost of car = $12,000

Estimated useful life = 5 years

Residual value = $2,000

Depreciable amount = $10,000 ($12,000 - $2,000)

Straight-line Depreciation (annual) = $2,000 ($10,000/5)

Depreciation for first year (April 3) = $1,496 ($2,000 x 273/365)

≈ $1,500

Thus, using the straight-line method, the depreciation expense for the car in each year is $2,000.

According to the population function, the population of mosquitoes in the area at any time is 400000 = 200000e⁷ⁿ

Population function:

The term population function refers the effective population served over the course of a time

Given,

The population of mosquitoes in a certain area increases at a rate proportional to the current population, and in the absence of other factors, the population doubles each week. There are 200000 mosquitoes in the area initially , and predators (birds, bats, and so forth) eat 20000 mosquitoes/day.

Now, we need to determine the population of mosquitoes in the area at any time.

Here we have given that we have two time frames in the information given; weeks and days.

Now, we need the population after predation lets choose time in days.

And we also know that the population doubles every seven days (ignoring predation) so if P(a) is the population function we have IVP

For one week, the population function of the given situation is written as

=> dP/dt = rP

Then the value of P is P(0) = 200000

And through the given question we know that,

=> P(7) = 2P(0)

While we solving the function then we get

P = Ceⁿᵃ

When we apply the values of P(0) = 200,000 then we get the value of C = 200,000

Then, the function is rewritten as

P = 200000eⁿᵃ

Now, we have to apply the value of P(7) = 2P(0), then we get,

400000 = 200000e⁷ⁿ

When we simplify it then we get,

e⁷ⁿ = 1/2

When we apply the number of days on these function, then we can get the number of mosquitoes in the city.

Answer:

Determine whether the equation is half or double the given number, then solve for x.

Step-by-step explanation:

The hash marks on the sides of the triangles tell you that the pieces of the triangles are the same length. The piece with one mark is the same length as the other piece with one mark. The piece with two marks is the same length as the other piece with two marks.

This is important because it tells you that the place where the triangle is divided is at its halfway point — so, the triangles are cut right in half. The line that cuts the triangle in half will always be half the length of the line that is the bottom of the triangle. You can use this to solve for x in each of these problems.

12) We are trying to solve for x along the length of the longer line. The halfway-point line is seven.

Seven is half of fourteen (7*2=14). So, the longer line is 14.

Since the longer line has the equation 2x, we must determine what times two is fourteen. To find that, we would divide fourteen by two (division and multiplication are inverse operations). 14/2=7.

x=7.

15) We are trying to solve for x along the length of the shorter line. The longer line is 35.

The shorter line is half of the longer line, so in this case it is half of 35, which is 17.5.

However, in the equation, we subtract 8 from x. So, we have to find the number that becomes 17.5 only after you subtract 8. To do this, you simply add 8 to 17.5 (addition and subtraction are inverse operations). 25.5 - 8 = 17.5.

x = 25.5.

The families of solutions (variable x) for the square root of the trigonometric expression 2 · cos x - 1  equal to 0 are x₁ = π / 6 + i · 2π and x₂ = 11π / 6 + i · 2π, where i is an integer.

In this question we find the following trigonometric expression:

√(2 · cos x - 1) = 0

Where x is measured in radians.

By algebra properties and trigonometric formulas we must solve the trigonometric expression for x. First, use algebra properties until the trigonometric function is cleared:

√(2 · cos x - 1) = 0

2 · cos x - 1 = 0

2 · cos x = 1

cos x = 1 / 2

Second, find the family of solutions for the square root of the trigonometric function:

x₁ = π / 6 + i · 2π, where i is an integer.

x₂ = 11π / 6 + i · 2π, where i is an integer.
