Answer:

Step-by-step explanation:

Substitute x = 3 into g(x) then substitute the value obtained into g(x)

g(- 3) = (- 3)² - 2(- 3) - 7 = 9 + 6 - 7 = 8

g(8) = 8² - 2(8) - 7 = 64 - 16 - 7 = 41

The area of a square for on a scale drawing of 100 square centimeters and the scale drawing to 1 cm: 2 feet what is the area of

lilavasa [31]

Answer:

1. $\boxed{\text{400 ft}^{2}}$ ; 2. $\boxed{\frac{1}{3716}}$

Step-by-step explanation:

Step 1. Calculate the area of the floor

If the area A₁ of a square floor on the scale drawing is 100 cm², the length of a side is 10 cm.

The side length l of the actual floor is

l = 10 cm × (2 ft/1 cm) = 20 ft

The area A₂ of the floor is

A = l² = (20 ft)² = $\boxed{\text{400 ft}^{2}}\\$

Step 2. Calculate the area ratios

We must express both areas in the same units.

Let's express the area of the room in square centimetres.

l = 20 ft × (12 in/1 ft) = 240 in

l = 240 in × (2.54 cm/1 in) = 609.6 cm

A₂ = l² = (609.6 cm)² = 371 612 cm²

The area A₁ on the scale drawing is 100 cm².

The ratio of the areas is

$\frac{A_{1}}{ A_{2}} = \frac{100}{371612} = \frac{1 }{3716}\\$

The ratio of the area in the drawing to the actual area is $\boxed{\frac{1}{3716}}$

Answer: Choice [D] - "power of a power" ✅

Step-by-step explanation:

Hii, do you need to know which law you should use to simplify $\sf\bigg(x^4\bigg)^9$ ?

No problem!

The law we will use here is "power of a power".

What "power of powers" means is we raise a power to a power, which is exactly what we do here: We raise x^4 to the power of 9. To simplify our expression, we multiply the powers. ( $\boldsymbol{4\cdot9}$ )

So the right answer is: Choice [D] - "Power of a power"

The simplified answer is $\LARGE\boldsymbol{x^{4\cdot9}=x^{36}}$

Voila! There's our answer, cheers!

Hope that this helped! Best wishes.

<span>1. The current ratio (assets/liabilities) of company X is 3.1. Given that the current assets are $186000, find the current liabilities:

Assets = A
Liabilities = L

A / L = 3.1 => L = A / 3.1

A = 186000 => L = 18600 / 3.1 = 6000

Answer: $ 6000

2. The board of directors determines that the current ratio must never be below 2.6. What is the maximum amount that the company can borrow?

A/L ≥ 2.6

=> L ≤ A / 2.6

=> L ≤ 186000 / 2.6

L ≤ 71538.46

Answer: $71538.46
