Answer:

The answer is 544. The distributive property is a property that basically says that any number outside the parenthesis can be multiplied and distributed between all other numbers in the parentheses.

Step-by-step explanation:

17(11+21) = [This is the given equation]

17*11 + 17*21 [I used the distributive property]

187+357 [I used a calculator for the sake of time, but I suggest when double digit multiplying, do it by paper.]

= 544 [The answer is 544.]

The distributive property is a property that basically says that any number outside the parenthesis can be multiplied and distributed between all other numbers in the parentheses. An example is w(x+y+z). w(x+y+z) can also be simplified to (wx+wy+wz) because w is being distributed between all variables in the parenthesis. You can also get rid of parenthesis after simplifying.

The distributive property is also used when doing 'F.O.I.L'.

A "solution" is where the graph crosses the
x-axis so while the quadratic has no real solutions, the straight line passing through it does as it intersects the x-axis at x=-2.
Hope this helps! :)

Researchers at a lake have determined that the percentage of fish in the lake that are intolerant to pollution can be estimated

dusya [7]

Answer:

a. 23.02 %

b. 49%

c. W

Step-by-step explanation:

Solution:-

- A multi-variable function for the percentage of fish in the lake that are intolerant to the pollution is given as:

$P ( W , R , A ) = 49 - 1.61W - 1.41R - 1.38A$

Where,

W: percentage of wetland

R: percentage of residential area

A: percentage of agriculture

- We are to evaluate the percentage of fish intolerant to pollution in the case where W = 3 , R = 15 , A = 0. We will plug in the values in the modeled function P ( W , R , A ) as follows:

$P ( 3 , 15 , 0 ) = 49 - 1.61*3 - 1.41*15 -1.38*0\\\\P ( 3 , 15 , 0 ) = 23.02\\$

- To determine the maximum percentage of fish that will be intolerant to pollution we will employ the use of critical points. The critical point that is defined by the linear relationship between P and all other parameters ( W, R , A ). The maximum value occurs when W = R = A = 0.

$P ( 0 , 0 , 0 ) = 49 - 1.61*0 -1.41*0 - 1.38*0 = 49$

- Hence, the maximum value of the function is 49%.

- The linear relationship between each induvidual parameter ( R, W , A ) and the function ( P ) is proportional in influence. The extent of influence can be quantized by the constant multiplied by each parameter.

- We see that that ( 1.61*W ) > ( 1.41R ) > ( 1.38A ). The greatest influence is by parameter ( W ) i.e the influence of percentage of wetlands .

4 consecutive numbers that add up to 8

Digiron [165]

Answer:

The answer top your question is: 1/2, 3/2, 5/2 and 7/2

Step-by-step explanation:

Data

4 consecutive numbers that add up to 8

First number = n

2nd number = n + 1

3rd number = n + 2

4th number = n + 3

Now, add them up n + n + 1 + n + 2 + n + 3 = 8

Simplify like terms

4n + 6 = 8

4n = 8 - 6

4n = 2

n = 2/4 = 1/2

First number = n = 1/2

2nd number = n + 1 = 1/2 + 1 = 3/2

3rd number = n + 2 = 1/2 + 2 = 5/2

4th number = n + 3 = 1/2 + 3 = 7/2
