Answer:

\large\boxed{(t\times s)(x)=4x^3-28x^2+3x-21}

Step-by-step explanation:

s(x)=x-7\\t(x)=4x^2+3\\\\(t\times s)(x)=t(x)\times s(x)\\\\\text{Substitute:}\\\\(t\times s)(x)=(4x^2+3)(x-7)\\\\\text{use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\(t\times s)(x)=(4x^2)(x)+(4x^2)(-7)+(3)(x)+(3)(-7)\\\\=4x^3-28x^2+3x-21

In a crazed neighborhood they are replacing the speed limit signs that give the speed in m/s.
Lilit [14]

Answer:

11 m/s

Step-by-step explanation:

In converting from mph to m/s, the appropriate conversion factor must be used which in this case is 0.44704 m/s.

Thus;

If 1mph = 0.44704 m/s

Then 25 mph = 25 × 0.44704 m/s = 11.176 m/s

There is a strong positive linear correlation between rainfall and the number of peaches a tree produces. does this mean that mo
yulyashka [42]
A strong positive correlation means that as one variable increases so does the other and that they do so in a linear relationship. So what this means is that “as the rainfall increases, the number of peaches a tree produces increases.”

It does not mean that the rainfall causes the tree to produce more peaches. The correlation only establishes that the two variables are related in that one increases as the other does. It is NOT the case that this means for sure one causes the other. We cannot assume causality when using a correlation.

It might be that the rain causes more peaches to grown or it might be that some other factor or combination of factors causes the growth. We just do not know.

According to the synthetic division below, which of the following statements are true?
statuscvo [17]

A, D and E are correct

given ( x - 4 ) is a factor then x =  4 is a root

the remainder on division by (x - 4 ) = 0 as indicated by the 0 on the right side of the quotient

(x - 4 ) is a factor of 3x² - 13x + 4 → A

the number 4is a root of f(x) = 3x² - 13x + 4 → D ( explained above )

thus 3x² - 13x + 4 ÷ (x - 4 ) = 3x - 1 → E

the quotient line 3 - 1 0

3 and - 1 are the coefficients of the linear quotient and 0 is the remainder
