Answer: 1675 Ft. = Distance from

fire to the windmill.

Step-by-step explanation:

tan8 = 140/X1.

X1 = 140/tan8 = 996.2 Ft.

tan3 = 140/(996+X2)

996+X2 = 140/tan3 = 2671

X2 = 2671-996 = 1675 Ft. = Distance from

fire to windmill.

The confidence interval based on the two-sample design is wider because there is considerable variation in mileage between the cars. The confidence interval based on the paired design is wider because there is little variation in mileage between the cars. The confidence interval based on the two-sample design is wider because there is little variation in mileage between the cars. The confidence interval based on the paired design is wider because there is considerable variation in mileage between the cars.

Answers

Answer:

The confidence interval based on the paired design is wider because there is little variation in mileage between the cars.

Step-by-step explanation:

The sample size randomly collected is matched sample and since the confidence interval is based on the paired design is large and wide. There is small variation between the mileage of the two cars indicating the cars have mileage based on the fuel.

Which function is the inverse of f(x) = -x^3 - 9?

Answers

Answer:

(2)

Step-by-step explanation:

Let f(x) = y → f-¹(x) = f(y) = x, f(y) is the inverse of f(x)

Thus,

=> -x³ - 9 = y

=> - y - 9 = x³

=> (-y - 9)^(1/3) = x

=> f(y) = x

Inverse is (-y-9)^(1/3)

Replacing the variable, inverse is (-x-9)^(1/3)

Find the Surface Area. I need the answer fast.

Answers

Answer:

1615

Step-by-step explanation:

Area of triangle is: A= B•H•1/2

Area of square is A= L•W

39•17•1/2= 331.5

331.5•4= 1326

17•17= 289

Add the square area to the area of the triangles

289+ 1326= 1615

hope this helps chu <3

Answer:

663

Step-by-step explanation:

Since we are finding the area we multiply Length times Width which is a way of finding formal. L x W so the Length is 17 and Width is 39 so

17 x 39 = 663. So the area is 663

[tex]Area = 0.5 * (14ft\ 2in) * (8ft\ 6in)[/tex]

Convert to ft [divide by 12]

[tex]Area = 0.5 * (14+ 2/12) * (8+ 6/12)[/tex]

Answer:

  A'(-3, 13)

Step-by-step explanation:

The transformation that moves a point 4 left and 8 up is ...

  (x, y) ⇒ (x -4, y +8)

The transformation that reflects a point across the y-axis is ...

  (x, y) ⇒ (-x, y)

Applied after the translation, the transformation of ∆ABC becomes ...

  (x, y) ⇒ (-(x -4), y +8) = (4 -x, y +8)

Then point A gets moved to ...

  A(7, 5) ⇒ A'(4 -7, 5 +8) = A'(-3, 13)

* ♡ The Answer ♡      

・B = -11/13

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*      

♡ The Explanation/Step-By-Step ♡      

・1/7 = 90/91 + B

Switch sides!

90/91 + B = 1/7

Subtract 90/91 from both sides!

90/91 + B - 90/91 = 1/7 - 90/91

Simplify!

90/91 + B - 90/91 : B

90/91 + B - 90/91

90/91 - 90/91 = 0

= B

Simplify!

1/7 - 90/91 : -11/13

1/7 - 90/91

= 13/91 - 90/91

Combine the fractions!

= 13 - 90 over 91

Subtract the numbers! : 13 - 90 = -77

= -77/91

Apply the fraction rule! : -a/b = -a/b

= -77/91

Cancel the common factor! : 7

= -11/13

B = -11/13
