A paved walkway around a garden has an outer diameter of 80 ft and an inner diameter of 40 ft. A diagram is shown below.

Given:

  • Outer diameter = D = 80 ft
  • Inner diameter = d = 40 ft

So,

Outer radius = R = D/2

=> R = (80 ft)/2

=> R = 40 ft

Inner radius = r = d/2

=> r = (40 ft)/2

=> r = 20 ft

Area of paved pathway = πR² - πr²

= π(R² - r²)

= π(R + r)(R - r)

= π(40 + 20)(40 - 20) ft²

= π(60)(20) ft²

= 3.14 * 1200 ft²

= 3768 ft²

The point (17,−9) is translated to the point (6,2). Select the description of the translation.
zubka84 [21]

Answer:

11 up , 11 left

Step-by-step explanation:

Given

(17, -9) to (6,2)

Required

Determine the translation rule

Considering the x coordinates.

From 17 to 6

6 is to the left of 17.

Using the translation rule:

x = x' + b

17 = 6 + b

17 - 6 = b

11 = b

b = 11

<em>Hence: From 17 to 6 is 11 units left translation</em>

Considering the y coordinates.

From -9 to 2

2 is at the top -9.

Using the translation rule:

y = y' + b

-9 = 2 + b

-9 - 2 = b

-11= b

b = -11

The negative value impies a upward translation.

Hence: From -9 to 2 is 11 units up translation

What is the standard form of this function?<br> F(x) = -(x-4)^2 + 2
Marysya12 [62]

Answer:

f (x) = -2 (x + 6)^2 + 2

Step-by-step explanation:

f (x) = -2x^2 - 24x - 70 <--- divide out -2 out of the first two terms...

f (x) = -2 (x^2 + 12x) - 70 <-- divide the x coefficient by 2 and then square it, then add AND subtract it)  

f (x) = -2 (x^2 + 12x + (12/2)^2 - (12/2)^2) - 70  

f (x) = -2 (x^2 + 12x + 36 - 36) - 70 <--- distribute the -2 onto -36 to get it out of the brackets..  

f (x) = -2 (x^2 + 12x + 36) + 72 - 70 <-- combine constants and factor perfect square trinomial...  

f (x) = -2 (x + 6)^2 + 2 <-- standard form...

A local car dealership sells Buicks and Hondas. The following data shows the number of buyers this month according to the brand
Lina20 [59]

Answer:

16%

Step-by-step explanation:

The data provided on brand purchased by age group is.

\begin{array}{ccc}Age&Buick&Honda\\Under\ 40&6&17\\40\ or\ older&19&8\end{array}

A total of 50 cars were sold this month.

Since the number of buyers 40 years or older that purchased a ​Honda is 8, the percentage is:

P=\frac{8}{50}=0.16=16\%

16% of buyers were 40 years or older and purchased a​ Honda.
