Bob eats 1/4 of a pie and later eats 2/5 of the pie. What fractions remains?

Answer:

Kite is 89.52 ft off the ground

Step-by-step explanation:

We are told that the string is 200 ft long.

That the string is 5 ft off the ground at an angle of 25° to the horizontal.

I have drawn a triangle to depict this illustration with x being the height of the kite from the end of the string.

Also, I have depicted the ground level which is 5 ft below the end of the string.

From the triangle, we can calculate the height of the kite above the end of the string using pythagoras theorem.

x/200 = sin 25

x = 200 sin 25

x = 200 × 0.4226

x = 84.52 ft

Now, the bottom of the kite is 5 ft off the ground as depicted in the attachment.

Thus, height of kite above the ground = 84.52 + 5 = 89.52 ft

c. tan^2(2x)

Step-by-step explanation:

The required simplified expression is given as tan²(2x). Option c is correct.

[CSC(4x) - cot(4x) ] / [CSC(4x) + cot(4x) to be simplified.

The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.

[tex]= [csc(4x) - cot(4x)] / [csc(4x) + cot(4x)] \\= [1/sin4x - cos4x/sin4x] / [1/sin4x  + cos4x/sin4x]\\= [(1-cos4x)/sin4x] / [(1+cos4x) /sin4x] - - - - (1)[/tex]
Here,
[tex]1 - cos4x = 2sin^24x[/tex]

 [tex]sin4x = 2sin2xcos2x,\\ 1+cos4x = 2cos^22x[/tex]
now put the value in equation 1
[tex]= [(2sin^22x)/2sin2xcos2x] / [(2cos^22x) /2sin2xcos2x] \\= [(sin2x)/cos2x] / [(cos2x) /sin2x] \\=tan2x/cot2x\\=tan^22x[/tex]

Thus, the required simplified expression is given as tan²(2x). Option c is correct.

Step-by-step explanation:

The vertex form of the parabola is given by  

Comparing this equation with vertex form of a parabola , where (h,k) is the vertex

h = 2

k = 3

Hence, vertex is (2,3)

Now, axis of symmetry of a parabola passes through the vertex and divide the parabola in two equal halves.

Hence, axis of symmetry of the parabola is given by

x = h

[tex]g(x) = -3x[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 3x[/tex]

Required

Reflect over [tex]y = 0[/tex]

This means that we reflect over the x-axis

And the rule of reflection is:

[tex](x,y) \to (x,-y)[/tex]

Hence:

[tex]f(x) = 3x[/tex]

Will become:

[tex]g(x) = -f(x)[/tex]

So, we have:

Answer:

A

Step-by-step explanation:

Intercepts are basically points where if one of the coordinates is a number above 0, the other one HAS TO BE 0

Since there are three points where there are x-intercepts (since the y is 0), there will be three x-intercepts.

Since there is only one point where there are y-intercepts (since the x is 0), there will be only one y-intercept.

The intercepts don't give an exact answer so you would have to estimate where they are on the graph. For example, the y-intercept is between 20-30 and is leaning more towards 30, so you would think it's around 27-29 (And if you look at option A, you can see that it's (0,28))

You got the answer wrong because for one of the x-intercepts, you said that it was negative when it was actually positive. (I believe it was the (2.3,0) one.)

Answer:

(x - 6)² + y² = 4

Step-by-step explanation:

x² + 32 = -y² + 12x

Rearrange

x² - 12x + y² = -32

Complete the square for x

(x - 6)² + y² = -32 + (-6)²

(x - 6)² + y² = -32 + 36

El número de facturas

5 lempiras = 10 billetes

20 lempiras = 15 billetes

Step-by-step explanation:

Vamos a representar

El número de facturas de

5 lempiras = x

20 lempiras = y

Nuestro sistema de ecuaciones se da como:

x + y = 25 ..... Ecuación 1

x = 25 - y

5 × x + 20 × y = 350

5x + 20y = 350 .... Ecuación 2

Sustituiríamos x por 25 - y en la ecuación 2

5 (25 - años) + 20y = 350

125 - 5 años + 20 años = 350

125 + 15 años = 350

15 años = 350 - 125

15 años = 225

y = 225/15

y = 15

Resolviendo para x

x = 25 - y

x = 25 - 15

x = 10

Por lo tanto, el número de facturas

5 lempiras = 10 billetes

20 lempiras = 15 billetes

So your answer is:

y>3x+2

Step-by-step explanation:

the answer is in the above image

The distance between point A and point B is 10 units.

The distance between two points on a coordinate plane (x, y) and (x, y) is

= √[(x₂ - x₁)² + (y₂ - y₁)²] units

The given straight line is 3x + 4y = 24.

This straight line will cut the x-axis at a point where y = 0.

Therefore, 3x + 4(0) = 24

⇒ 3x = 24

⇒ x = 8

Therefore, the coordinates of the point A is (8, 0).

Similarly, this straight line will cut the y-axis at a point where x = 0.

Therefore, 3(0) + 4y = 24

⇒ 4y = 24

⇒ y = 6

Therefore, the coordinates of the point B is (0, 6).

Therefore, the distance between point A and point B is

= √[(0 - 8)² + (6 - 0)²] units

= √(64 + 36) units

= √100 units

= 10 units   (negative sign is avoided.)
