Describe the end behavior of the function graphed below.

Answer:

  (b) 150 feet

Step-by-step explanation:

You want to know the height of a kite at the end of 225 feet of string, flying at an angle of elevation of 45°.

The 45° angle in the given right triangle tells you this is one of the "special" right triangles. Its side lengths have the ratios ...

  1 : 1 : √2

where √2 is the hypotenuse.

That means the other two legs of this right triangle are ...

  (225 ft)/√2 ≈ 159.099 ft

Rounded to the nearest 50 feet, this is about 150 feet.

__

Additional comment

The sine function relates the angle value to the opposite side:

  Sin = Opposite/Hypotenuse

  Opposite = Hypotenuse · Sin

  height = (225 ft)·sin(45°) = 225 ft/√2 ≈ 159.099 ft

Two approximations of the area of the region between the graph are

(9, 11)

Given;

To calculate two approximations of the area of the region between the graph of the function and the x-axis across the given interval, use the left and right endpoints and the specified number of rectangles. rectangles f(x) = 2x + 3, [0, 2], 4

The graph is positive and the width of each subinterval will be,

a = 0, b = 2, n = 4

Δx = b-a/n = 2-0/4

     = 0.5

Now for different values;

x → f(x) = 2x+3

x₀ = 0 → f(x₀ ) = 2x+3 = 2(0)+3 = 3

x₁ = 0.5 → f(x₁) = 2x+3 = 2(0.5)+3 = 4

x₂ = 1.0 → f(x₂) = 2x2+3 = 2(1) +3 = 5

x₃ =1.5 → f(x₃) = 2x+3 = 2(1.5)+3 = 6

x₄ = 2 → f(x₄) = 2x+3 = 2(2)+3 = 7

The area by using the approximation using 4 approximating rectangles and right endpoints is given by,

A ≈ R₄ = ∑f(x) Δx = ( ƒ(x1)Δx + ƒ (x2)Δx+ ƒ (x3)Δx + ƒ (x4)Δx)

          = 0.5 (4 + 5 + 6 + 7)

          = 0.5 × 22

          = 11

The area by using the approximation using 8 approximating rectangles and left endpoints is given by.

A ≈ L₄ = ∑f(x) Δx = ( ƒ(x0)Δx + ƒ (x1)Δx+ ƒ (x2)Δx + ƒ (x3)Δx)

          = 0.5 (3 + 4 + 5 + 6)

          = 0.5 × 18

          =9

Thus, 9 < Area < 11.

Answer: 1/2

Step-by-step explanation: Divide both the numerator and denominator by the GCD (Greatest Common Denominator)

27 ÷ 27

The unit rate is 32.6 ft/s and approximately 0.03 s/ft.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

An object traveled 691.12 feet in 21.2 seconds.

So, the unit rate as feet per second.

= 691.12/ 21.2

= 32.6 ft/s

and, the unit rate as second per feet

= 21.2/ 691.12

= 0.03 s/ ft

Hence, the unit rate is 32.6 ft/s and approximately 0.03 s/ft

The reason that proves the above conditions is option A. Definition of supplementary angles And Substitution property.

The pair of angles that gives 180° on adding is known as Supplementary angles. In other words, the sum of two supplementary angles is 180°. Two pairs of Supplementary angles will always form a linear pair.

Here we have

∠1,  ∠2,  ∠3, and ∠4 are formed by 2 intersecting lines

As we know      

∠1,  ∠2 is a linear pair and form supplementary angles

=> Sum of the ∠1,  ∠2 will equal 180°  

∠2,  ∠3 is a linear pair and form supplementary angles

=> Sum of the ∠2,  ∠3 will equal 180°  

Therefore,

By the Definition of supplementary angles ∠1+∠2= 180° and ∠2+∠3= 180°

From the above observations,

=> ∠1+∠2= 180° and ∠2+∠3= 180°

=> ∠1 + ∠2 = ∠2 + ∠3  

Therefore,

By the Substitution property ∠1 + ∠2 = ∠2 + ∠3

The value of x in the rectangle is  -5 + 5√3.

A rectangle is a quadrilateral with opposite sides equal to each other. Opposite sides are parallel to each other.

Therefore, the area of a rectangle can be found as follows:

area of a rectangle = lw

where

Therefore,

length = x + 10

width = x

Hence,

50 = x(x + 10)

50 = x² + 10x

x² + 10x - 50 = 0

using quadratic formula,

[tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] and [tex]\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]

a = 1

b = 10

12 is the marginal cost at the production level of 1000 units.

A differential equation is an equation that contains one or more functions with its derivatives.

The marginal cost represents the additional cost if 1 more unit is produced. So, we can find the marginal cost by computing C(1,001) and subtracting (1,000)

First, let's evaluate the cost at both x= 1,001 and x=1,000

C(1000)=0.002(1000)^2+8(1000)+6000

=0.002(1000000)+8000+6000

=2000+8000+6000

=16000

C(1001)=0.002(1001)^2+8(1001)+6000

=2004.002+8008+6000

=16012

The difference between these costs is $12.002. Rounding to the nearest cent, we find a marginal cost of $12 per unit. Let's see if we get a similar result from the derivative.

Hence 12 is the marginal cost at the production level of 1000 units.

As per the angle sum property of quadrilateral, then values of x is 245 and the value of y is 341

Angle sum property of quadrilateral:

The angle sum property states that the sum of all the angles of the quadrilateral is 360 degree.

Given,

The angles of the quadrilateral are 5x degrees, (4y minus 2 )degrees, (13x plus 10 )degrees, and 10y degrees.

Now we have to write and solve a system of linear equations to find the values of x and y.

While we looking into the given angles, then we get the values

=> 5x°

=> (4y - 2)°

=> (13x + 10)°

=> 10y°

We know that, the sum of all the angles of the quadrilateral is 360°.

So, it ca be written as,

=> 5x° + (4y - 2)° + (13x+ 10)° + 10y° = 360°

=> 18x° + 14y° - 8° = 360°

=> 18x° + 14y° = 354°

When we divide all of them by 2, then we get the equation as,

=> 9x° + 7y° = 177°

Now we have to rewrite the given equation as,

=> 9x° = 177° - 7y°

=> x° = (177° - 7y°)/9

Apply these value on the angles, then we get,

=> 13(177 - 7y)/9 = -10

=> 13(177 - 7y) = 90

=> -7y = -90 - 2301

=> 7y = 2391

=> 341

Then the value of x is

Answer:

Step-by-step explanation:

Slope of a straight line is the gradient of that line.

Formula for gradient is rise over run. Meaning: m = (y2 - y1) / (x2 - x1)

To use this formula, you need 2 points of the straight line. They have already given you one: (8, -3). For the second one, we consider the equation of the line. The y-intercept is given too: -4.

Now, keep in mind, the y intercept is the point of the line that passes from x = 0. Meaning, the point where the line touches the y axis, and at y axis, x = 0. So our second point is (0, -4).

Now as we have 2 points, (8, -3) and (0, -4), we put the values in the formula: m = (y2 - y1) / (x2 - x1) = (-4 - (-3)) / (0 - 8) = -1 / -8 = 1 / 8

Answer:

c) divide both sides by 8

Answer:

y = 1/2x + 3

Step-by-step explanation:

first we change the first equation to slope-intercept form to find the reciprocal slope

2y - 4x = -10

add 4x to both sides

2y = 4x - 10

divide both sides by 2

y = 2x - 5

since perpendicular lines have reciprocal slopes the slope of our new line is 1/2

y = 1/2x + b

to find b we plug in the point

1 = 1/2(-4) + b

1 = -2 + b

add 2 to both sides

Using the estimate formula, for standard margin of error

Margin of error (E) = Z x √p(1-p)/n

where , E---> margin of error

p----> sample proportion

n -----> Sample size

we have the value of E = 0.06 , p = 18% = 0.18
