3 0

<h3>Given:</h3>

r= 7.5 m

r= radius

The circumference of the circular playing field.

<h3>Solution:</h3>

$\huge\boxed{Formula:C= 2\pi{r}}$

We'll have to multiply 2, π and radius.

Substitute the values according to the formula.

$C= 2× \pi ×7.5$

$C= 47.12389$

$\large\boxed{C= 47.12 \: m}$

Therefore, the circumference of the circular playing field is 47.12 feets.

Answer:

1. 40.97 2. 52.93 3. 32.00 4. 26.00

Step-by-step explanation:

remember that area =1/2 * b * h so to find base, you can make it the subject of formula i.e

b =area *h/2

or in the caseof h you can do

h= area * b/2

Lin took 75 boxes of carrots and 80 boxes of potatoes to the market. She sold 68 boxes of carrots and 71 boxes of potatoes. How

enot [183]

For this case we have:

x: Represents the number of carrot boxes

y: Represents the number of boxes of potatoes

Initially we have:

$x = 75\\y = 80$

If you sold 68 boxes of carrot we have:

$x = 75-68 = 7$

If you sold 71 boxes of potatoes, we have:

$y = 80-71 = 9$

The number of boxes I take home is given by: $x + y = 7 + 9 = 16$

ANswer:

7 boxes of carrots left

There are 9 boxes of potatoes left

A total of 16 boxes remain

What are the zeros of the polynomial function? F(x)= x^2 +12x

Pavel [41]

Answer:

x = 0 and x = -12 are the two zeroes

Step-by-step explanation:

"Zeroes" of a function are also called the solutions, roots or x intercepts.

The zeroes are the numbers that give the function a values of 0, so find what value for 'x' yields F(x) = 0 as a result.

With quadratic equations (equations with x² as the largest exponent), you factor the equation.

Step 1: Set the equation equal to zero

x² + 12x = 0

Depending on the equation, there are several methods you can use to factor, for this one we can factor out an 'x' since both terms have an 'x' in them. We get...

x(x + 12) = 0

So now, using the "zero product property" which means that if two things are multiplied together, and the result is zero, then either the first term is zero, the second term is zero, or they are both zero. So we set each term equal to zero and solve.

either x = 0 or x + 12 = 0

Solve each for x to get your two anwers.

x= 0 is already solved, so 0 is our first zero

Now solve

x + 12 = 0

x = -12 (subtract 12 from both sides to isolate x)
