If you have two identical and symmetrical objects and divide one into 4ths and the other into 6ths, the pieces of the object divided into 4ths will be larger than the pieces of the object divided into 6ths.

1/4 = 25 4/4 = 100
1/6 = 16.66... (17) 6/6 = 100
25 > 17

at farm the ratio of cows to horses was 10:3if there were 20 cows at the farm how many horses were there

If you think the cows are doubled so if you double the amount of horses so the ratio is 10:3 so 20:6 is the new ratio the answer would be 6 horses

Consider the function below. (If an answer does not exist, enter DNE.) g(x) = 190 + 8x3 + x4 (a) Find the interval of increase.

galben [10]

Answer:

The interval of increase of g(x) is $(-6,+\infty)$ .

Step-by-step explanation:

The interval of increase occurs when first derivative of given function brings positive values. Let be $g(x) = 190 + 8 \cdot x^{3} + x^{4}$ , the first derivative of the function is:

$g'(x) = 24 \cdot x ^{2} + 4\cdot x^{3}$

$g'(x) = 4 \cdot x^{2}\cdot (6+x)$

The following condition must be met to define the interval of increase:

$4\cdot x^{2} \cdot (x+6) > 0$

The first term is always position due to the quadratic form, the second one is a first order polynomial and it is known that positive value is a product of two positive or negative values. Then, the second form must satisfy this:

$x + 6 > 0$

The solution to this inequation is:

$x > - 6$

Now, the solution to this expression in interval notation is: $(-6,+\infty)$

PARALLEL LINES <br>Find x and y. <br>

Georgia [21]

4x = (130 - 2x) so x = 65/3

(3y + 40) + (130 -2x) = 180 because the angles are supplementary

plug in x

3y + 40 + 130 - 2(65/3) = 180

so 3y = 95/3

therefore y = 95/6

What is the coefficient of a3 after simplifying this expression? 2a3−10ab2+3a3−ab2−7

Sergio [31]

Answer:

Step-by-step explanation:

Given the expression

2a^3−10ab^2+3a^3−ab^2−7

We are to find the coefficient of a^3

First is to collect the like terms;

2a^3−10ab^2+3a^3−ab^2−7

= 2a^3+3a^3−10ab^2−ab^2−7

= 5a^3-11ab^2-7

From the resulting equation, you can see that the coefficient of the term having a^3 is 5
