Which expression is equivalent to( 9x^2+2x-7)(-4)

Mathematics

Answer:  Option 'b' is correct.

Step-by-step explanation:

Since we have given that

(9x^2+2x-7)(x-4)

We need to find the equivalent form:

We will apply "Distributive law":

a\times b+a\times c\\\\=a\times (b+c)

So, it becomes,

x(9x^2+2x-7)-4(9x^2+2x-7)

Hence, Option 'b' is correct.

Answer:

I'm pretty sure its B. (9x2+2x-7)(x)+(9x2+2x-7)(-4)  

Because its just splitting up the (x-4) and if you add the answers together then you get the same answer as the original

Which of the following represents a weak positive correlation? And explain.
Soloha48 [4]

Answer:

  1. R= 0.2
  2. 2

Step-by-step explanation:

explaining the answer to 1

I'll explain everything so you understand.

The correlation coefficient tells us about the strength of the relationship between the variables. In other words, it tells us how well the data fits on the line of best fit.

So, the closer the points lie on the line of best fit the stronger the relationship and correlation.

The further the points lie from the line of best fit, the weaker the correlation

It is important to note that the correlation coefficient (r) always lies between -1 and 1.

So, the closer the value of r lies to -1 or 1 the stronger the relationship between the variables.

The closer the value of r is to 0 the weaker the relationship between the variables and the weaker the correlation.

explaining the answer to 2

the correlation coefficient (r) always lies between -1 and 1 so it can't be 2.

Hope this helps.

Marquise has 200200200 meters of fencing to build a rectangular garden.
adoni [48]

Hence the maximum possible area is 2500 square meteres

Given the area of the rectangular garden expressed as;

A(x)=-x^2+100x\\

The maximum area occurs when dA(x)/dx = 0

\frac{dA(x)}{dx} = -2x + 100\\0= -2x + 100\\ 2x = 100\\x = \frac{100}{2}\\x = 50

Next is to get the maximum area possible. Substitute x = 50 into the original function as shown;

A(50)= -50^2 + 100(50)\\A(50) = -2500+5000\\A(50) = 2500

Hence the maximum possible area is 2500 square meters
