Answer:

A. 288.62

Step-by-step explanation:

Area of two triangles = 15.3 * 10.4 = 159.12

Area rectangle = hypotenuse triangle * 7

hypotenuse = √108.16 + 234.09

Hypotenuse = 18.5

Area rectangle = 18.5 * 7 = 129.5

129.5 + 159.12 = 288.62

Answer = A. 288.62

Answer:

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.

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

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

Step-by-step explanation:

Anand = x

Sharma = x + 3

6 years ago

Anand = x - 6

Sharma = (x + 3) - 6

= x + 3 - 6

= x - 3

Sharma age = 4 (x - 6)

Six years ago Sharma's age was four times Anand's age.

x + 3 = 4(x - 6)

x - 3 = 4x - 24

x - 4x = -24 + 3

- 3x = - 21

x = - 21/-3

x = 7

Anand = x = 7 years

Sharma = x + 3

= 7 + 3

= 10 years

Answer:

Coice a

Step-by-step explanation:

O Choice A could be represented by a linear equation,

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

Choice A: $100 on January 1, $200 on February 1, $400 on March 1, $800 on April 1, and so on, with the amount doubling each month,

Choice B: $50 the first month, $100 the second month, $150 the third month, and so on, with $50 added each month,

Answer:

x = 33

<C = 81

Step-by-step explanation:

The sum of the angles of a triangle add to 180

x+  2x+ 2x+15 = 180

Combine like terms

5x+15 = 180

Subtract 15 from each side

5x +15-15 =180-15

5x = 165

Divide by 5

5x/5 =165/5

x = 33

<C = 2x+15 = 2(33)+15 = 66+15 = 81

Answer:

x = 33

c = 81

Step-by-step explanation:

Sum of three angles of triangle = 180

x + 2x + 2x + 15 = 180

Combine like terms

5x + 15 = 180

Subtract 15 from both sides

5x = 180 - 15

5x = 165

Divide both sides by 5

x = 165 /5

x = 33

∠C = 2x + 15 = 2*33 + 15 = 66 + 15 = 81°

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]

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:

The answer is below

Step-by-step explanation:

A unit circle is a circle on the coordinate plane with a radius of 1 unit. The unit circle center usually lies on the origin.

The equation of a circle is given as:

(x - h)² + (y - k)² = r²

Where (h, k) is the center of the circle and r is the radius of the circle.

As seen in the diagram attached, the center of the circle is at the origin (0, 0) and the circle is a unit circle with a radius of 1. Hence:

(x - h)² + (y - k)² = r²

(x - 0)² + (y - 0)² = 1²

x² + y² = 1

Given the point P(x, 1/2) lies on the circle. To find x, substitute y = 1/2:

x² + (1/2)² = 1

x² + 1/4 = 1

x² = 1 - 1/4 = 3/4

x² = 3/4

x = √(3/4)

[tex]x=\pm\frac{\sqrt{3} }{2} \\\\Hence\ P=(\frac{\sqrt{3} }{2},\frac{1}{2} )\ or\ P=(-\frac{\sqrt{3} }{2},\frac{1}{2} )[/tex]
