The length of flag is 760 feet and width of flag is 320 feet

Solution:

A seed company planted a floral mosaic of a national flag

Since, the flag is generally of shape rectangle, we can use the formula of rectangle

Let "a" be the length of rectangle

Let "b" be the width of rectangle

The length is 440 ft greater than the width

Length = 440 + width

a = 440 + b ----- eqn 1

The perimeter of the flag is 2,160 ft

The perimeter of rectangle is given as:

Perimeter = 2(length + width)

Substituting the given values, we get

2160 = 2(440 + b + b)

2160 = 880 + 4b

4b = 2160 - 880

4b = 1280

b = 320

Substitute b = 320 in eqn 1

a = 440 + 320

a = 760

Thus the length of flag is 760 feet and width of flag is 320 feet

Given functions are:

$f(x) = 0.5x^2-2$

and $g(x) = 8x^3+2$

Using both functions we need to find value of (f*g)(x)

(f*g)(x) simply means find product of f(x) and g(x) so we will multiply values of each function as shown below:

$(f*g)(x) = (0.5x^2-2)(8x^3+2)$

$(f*g)(x) = 0.5x^2(8x^3+2)-2(8x^3+2)$

$(f*g)(x) = 4x^5+1x^2-16x^3-4$

$(f*g)(x) = 4x^5-16x^3+1x^2-4$

$(f*g)(x) = 4x^5-16x^3+x^2-4$

Hence final answer is $(f*g)(x) = 4x^5-16x^3+x^2-4$ .

Annette [7]

The correct answer is $44.20.
If we add up all the tips, the total is $442. If we divide this by the number of days (10), then we find the mean.
442 / 10 = 44.2
