48[tex]x^{7}[/tex]y

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the height and b₁, b₂ the parallel bases , then

A = [tex]\frac{1}{2}[/tex] × 4[tex]x^{5}[/tex] × (9x²y + 15x²y )

   = 2[tex]x^{5}[/tex] × 24x²y

   = 48[tex]x^{7}[/tex]y

The simplified expression for the area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].

A trapezium is a quadrilateral with four sides where two sides are parallel to each other.

We have,

Trapezium.

Height = 4[tex]x^5[/tex]

Parallel sides are 15x²y and 9x²y.

The area of the trapezium.

= 1/2 x h x ( sum of the parallel sides )

Now,

Area of the trapezium.

= 1/2 x 4[tex]x^5[/tex] x (15x²y + 9x²y)

= 2[tex]x^5[/tex] x (15x²y + 9x²y)

= 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex]

Thus,

The area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].

Encontrar el perímetro de un triángulo con lados que miden 6 cm, 8 cm, y 12 cm. ... P = 2l + 2w, donde l es el largo del rectángulo y w l ancho del rectángulo. espe

Answer:

Step-by-step explanation:

D = 17 in

W = 12 in

H = ??

Monitor is a ractangle, so we can use the Pythagoeran theorem:

W² + H² = D²

12² + H² = 17²

H² = 289 - 144

H² = 145

H = √145 ≈ 12

The value of n is, 75.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

An inverse variation includes the points (15, 1) and (n, 5).

Now, We know that;

The inverse variation is defined as,

⇒ y = k x

Here, An inverse variation includes the points (15, 1) and (n, 5).

Hence, Substitute x = 15, and y = 1;

⇒ 1 = k × 15

⇒ k = 1/15

And, Substitute x = n and y = 5;

⇒ y = k x

⇒ 5 = 1/15 × n

⇒ 5 × 15 = n

⇒ n = 75

Answer:

The answer is below

Step-by-step explanation:

In a certain​ year, the amount A of garbage in pounds produced after t days by an average household is given by A = 7.5t.

Plot a graph for t > 0

how many days it will take to get 200 pounds of garbage.

Solution:

a) Let the time in days (t) be on the x axis and the amount of garbage (A) in pounds be on the y axis. Therefore:

At t = 0; A = 7.5(0) = 0

At t = 10; A = 7.5(10) = 75

The graph was plotted using the geogebra online graphing tool.

b) number of days require to get 200 pounds of garbage can be gotten by finding the value t for which A = 200. Therefore:

A = 7.5t

t = A / 7.5 = 200 / 7.5

t = 26.67 days

Answer:

Step-by-step explanation:

Assume the parabola is vertical.

y = a(x-0)^2 +7

y = ax^2 + 17

Plug in (1,-2) and solve for a

-2 = a1^2 + 17

a = -19

y = -19x^2 + 7

Answer:

B. 5

Step-by-step explanation:

Use the pythagorean theorem to solve: [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex].

[tex]a^{2}[/tex]+[tex]12^{2}[/tex]=[tex]13^{2}[/tex]

[tex]a^{2}[/tex]+144=169

Subtract 144 from 169.

[tex]a^{2}[/tex]-144=169-144

[tex]a^{2}[/tex]=25

Square root to get a.

[tex]\sqrt{a}[/tex]=[tex]\sqrt{25}[/tex]

Answer:

Yes it is simplified

Step-by-step explanation:

2x^2 is not a like term to 2x because 2x does not have an exponent. Therefore, you cannot add 2x to 2x^2. So it is as simplified as it can be at this point
