Four hundred grams of grass seed are used for every 100 m2. Find the amount of seed needed, in kilograms, to cover 3000 m2?

Answers

Answer 1

Answer: 400 / x = 100 / 3000 <=>
400 / x = 1 / 30 <=.>
x = 400 * 30 <=>
x = 12000 kilograms of grass.

Answers

first consider (x+c)^2 where c is just a random constant. if we expand this by foil (which is distributive property twice), we get x^2 + 2cx+ c^2. we want to find c^2 and to do that, we can first find c. we can find c by looking at the 2cx term. this term should match with 12x, so therefore 2c = 12 so c = 6. this also implies that c^2 = 36.
note that for this problem i was working backwards which is a very powerful problem solving tool: start with what you want to attain, and then see how you can go from where you are now to get to your destination.

Let the function f(x) have the form f(x) = Acos(x + C). To produce a graph that matches the one shown below, what must the value of A be?

Answers

A general cosine function has the form:

f(x) = A*cos(c + x)

We want to find the value of A that matches the one in the image, and we will find that A = 3

Ok, a general cosine function is:

f(x) = A*cos(c + x)

Where A is the amplitude.

To find the amplitude of a cosine function, we just need to find half of the difference between the maximum and minimum value of the function:

By looking at the given graph, we can see that the maximum is y = 3, and the minimum is y = -3

Then the amplitude is:

A = (3 - (-3))/2 = 6/2 = 3

The correct option is B.

Answers

Yes 2.99 is greater than 3.15 because The 3 is greater than 2 so you can see that its greater than:)
hope that helped :)

Yes because if you look at the ones place, 2 and 3, you see that 3 is greater than 2 so there fore it is false.

(2((x+1) ^3 – (x+1) ^2 + (x+1)) )+3

Answers

( x + 1 )^3 = x^3 + 3x^2 +3x + 1;
(x + 1 )^2 = x^2 + 2x + 1;
=> (2((x+1) ^3 – (x+1) ^2 + (x+1)) )+3 =2( x^3 + 3x^2 +3x + 1 - x^2 -2x - 1 + x + 1 ) + 3 = 2( x^3 + 2x^2 + 2x + 1 ) + 3 =
= 2x^3 +4x^2 +4x + 5.
