The length of the octagon is 6cm, the area is given by 3h and the height is 7.23 cm.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

In a triangle, the sum of all three angles is 180°

Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.

Given the octagon with a perimeter of 48 cm

Let's say the length of each side is a

Perimeter = 8a

8a = 48

a = 6cm

Now,

The area of the triangle is given by

A = 1/2  × Base × Height

A = 1/2  × 6 × h

A = 3h

Now

A = 3h and the area is 21.7 cm²

So,

h = 21.7/3 = 7.23 cm

Hence "The length of the octagon is 6cm, the area is given by 3h and the height is 7.23 cm".

So, anything in the first quadrant would be positive (for both values of x and y).

That means E and F are the correct choices, since both (4, 8) and (2, 2) are positive and would be found in the first quadrant.

[tex]H=210.25\ \text{units}[/tex]

Step-by-step explanation:

Given that,

[tex]H = -16t^2 + 84t + 100[/tex] ...(1)

We need to find the maximum height

For maximum height, put dH/dt = 0

[tex]\dfrac{d(-16t^2 + 84t + 100)}{dt}=0\\\\-32t+84=0\\\\t=\dfrac{84}{32}\\\\t=2.625\ s[/tex]

Put t = 2.625 in equation (1)

[tex]H = -16(2.625)^2 + 84(2.625) + 100\\\\=210.25\ \text{units}[/tex]

Hence, the maximum height [tex]=210.25\ \text{units}[/tex]

Step-by-step explanation:

Hope this helps. Pls give brainliest.

Answer:

x = 0

y = 3.25

Step-by-step explanation:

You can do elimination. Multiply (9x + 4y = 13) by 2

4x - 8y = -26

18x + 8y = 26

22x = 0

x = 0

4(0) - 8y = -26

-8y = -26

y = 3.25

Answer:

$159.1

Step-by-step explanation:

Given that:

Original price of surfboard = $199

Reduction of price done = 10%

Then a coupon is used by a customer for $20 off.

To find:

How many dollars were paid by the customer?

Solution:

First of all, let us find the price after the reduction of 10% from the original price.

10% of $199 = [tex]\frac{10}{100}\times 199 = \$19.9[/tex]

This price is reduced from the original price.

Price after reduction = $199 - $19.9 = $179.1

Now, again there is coupon of $20.

Therefore, final price that the customer had to pay = $179.1 - $20 = $159.1

Answer:

The nth term will be:

Step-by-step explanation:

Given the sequence

-5, -15, -25, ...

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]-15-\left(-5\right)=-10,\:\quad \:-25-\left(-15\right)=-10[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=-10[/tex]

The first element of the sequence is:

[tex]a_1=-5[/tex]

Thus, the nth term will be:

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting the values [tex]d=-10[/tex]; [tex]a_1=-5[/tex]

[tex]a_n=-10\left(n-1\right)-5[/tex]

[tex]a_n=-10n+5[/tex]

Plug in n = 93 to determine the nth term

[tex]a_{93}=-10\left(93\right)+5[/tex]

[tex]a_{93}=-930+5[/tex]

[tex]a_{93}=-925[/tex]

Therefore, the nth term will be:
