Option C

The distance of a spin of one full rotation is 31.4 feet

<em><u>Solution:</u></em>

Given that,

A circular merry-go-round has a radius of 5 feet

Radius = 5 feet

We have to find the distance of spin for one full rotation

Distance covered in 1 full of rotation is equal to circumference of circle

<em><u>The circumference of circle is given as:</u></em>

C = 2 \pi r

Where "r" is the radius

C = 2 \times 3.14 \times 5\\\\C = 6.28 \times 5\\\\C = 31.4

Thus the distance of a spin of one full rotation is 31.4 feet

Which function represents a reflection of f(x) =
liubo4ka [24]

If your original equation was f(x) = 3(2)^x, then a reflection over the x-axis means you need all the y-values to switch sign.  This means you need to multiply that function by -1.

    g(x) = -1\cdot 3(2)^x or  g(x) = -3(2)^x

Marysya12 [62]

Answer:

9.7303888 miles

Step-by-step explanation:

Given the following :

Set target = 12 miles per week.

Miles ran on Monday = 4 3/4 miles

Miles ran on Wednesday = 3 1/3 miles

Miles ran on Friday = 1 11/17 miles

Number of miles covered for the week:

(miles covered on Monday + miles covered on Wednesday + miles covered on Friday)

= (4 3/4 + 3 1/3 + 1 11/17) miles

= (19/4 + 10/3 + 28/17) miles

= (4.75 + 3.33333 + 1.6470588) miles

= 9.7303888 miles

EastWind [94]

Answer:

38,325 dinners.

Step-by-step explanation:

We have been given that last year the manager of a health care facility served 36,500 dinners. The manager estimates an increase of 5% in the number of dinners to be served next year.

The estimated number of dinners next year would be 36,500 plus 5% of 36,500.

36,500+(\frac{5}{100}\times 36,500)

36,500+(0.05\times 36,500)

36,500+1,825

38,325

Therefore, 38,325 dinners will be served next year.
