Answer:

666.6667 feet²

Step-by-step explanation:

So.

Since the scale is 1 : 20, we can do 4 x 20 and 5 x 20, Which is 80 and 100.

Find area: 80 x 100 = 8000 we can just add 2 zeros to 80 since it's multiplying by 100.

So it's 8000in²

Then we do 8000 in to feet.

Which is ≈ 666.6667feet

btw it asked for feet so we give them FEET

Answer:

The answer is 6 2/3 ft by 8 1/3 ft.

Step-by-step explanation:

The room will be 80 inches by 100 inches...

1 inch = 20 inches so

4 inch = 80 inches

and 5 inch = 100 inches.

This seems completely wrong but I just wanted to help out the other person who answered this to get brainliest.

Find (a) the slope of the curve at the given point p, and (b) an equation of the tangent line at p. y=−2−9x2; p(2,−38)

Neporo4naja [7]

Answer:

a) -36

b) y = -36x +34

Step-by-step explanation:

a) The slope is found using the derivative of the function.

f'(x) = dy/dx = 0 -9(2x) = -18x

Then at x=2, the slope is ...

f'(2) = -18·2 = -36

___

b) The point-slope form of the equation can be written as ...

y = -36(x -2) -38

Simplifying to slope-intercept form, we get ...

y = -36x +34

Find the next three sequence of 1,3, 9, 27,

Andreyy89

Answer: 81, 243, 729

Step-by-step explanation:

STEP ONE: Find a pattern in the sequence

3 ÷ 1 = 3

9 ÷ 3 = 3

27 ÷ 9 = 3

As we can see from the given sequence, each number multiplies 3 to get the next term.

STEP TWO: Find the next three terms

27 × 3 = 81

81 × 3 = 243

243 × 3 = 729

Hope this helps!! :)

I need help with answering the following questions. :/ :)

Answer:

a) (0, ∞)

b) (-∞, ∞)

c) x = 0

Step-by-step explanation:

It helps to have some idea what the log function is.

a) The domain is all positive numbers: (0, ∞).

b) The range is all real numbers: (-∞, ∞). (The vertical translation downward by 5 units does not change that.)

c) There is a vertical asymptote where the argument of the log function is zero: at x=0.
