Answer:

So the best of the given data is that of January in which the expenses almost equal the earnings. f(x)= g(x)

Step-by-step explanation:

Imports means buying and bringing in the purchases from the outside or another country.

When imports increase , expenses increase.

Exports means selling and sending out the goods to an another country.

When exports increase , earnings or profit increases.

Now looking at the data

January: the number of imports is equal to the number of exports, which means the amount spent is equal to the amount earned or almost the same.

f(x)= g(x)

February : the number of imports is greater than the number of exports,

6 > 4 which means the amount spent is greater to the amount earned.

f(x)> g(x)

March: the number of imports is greater than twice the number of exports,

9 > 5 which means the amount spent is greater than twice to the amount earned.

f(x)> g(x)

April: the number of imports is twice greater the number of exports,

12 > 6 which means the amount spent is twice greater than the amount earned.

f(x)= 2g(x)

So the best of the given data is that of January in which the expenses almost equal the earnings.

f(x)= g(x)

Answer is B.

We see the center lines are 80 and 85 as stated.

A is wrong because the range of class 2 is less.

C is wrong; class 2 has a minimum of 50

D is wrong; class 2 has a smaller interquartile range, which is the width of the boxes.

The surface area of the cone is 43.75pie cm^2. What is the slant height of the cone and the diameter is 5

Masteriza [31]

If the diameter of the cone is 5, then the radius of it will be half that, or 2.5, thus

$\bf \textit{total surface area of a cone}\\\\
SA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}+\pi r^2~~
\begin{cases}
r=radius\\
h=height\\
------\\
SA=43.75\pi \\
r=2.5
\end{cases}
\\\\\\
43.75\pi =\pi (2.5)\sqrt{r^2+h^2}+\pi (2.5)^2
\\\\\\
43.75\pi -\pi (2.5)^2=2.5\pi \sqrt{r^2+h^2}
\\\\\\
43.75\pi -6.25\pi =2.5\pi \sqrt{r^2+h^2}\implies 37.5\pi =2.5\pi \sqrt{r^2+h^2}
\\\\\\
\cfrac{37.5\pi }{2.5\pi }=\sqrt{r^2+h^2}\implies 15=\sqrt{r^2+h^2}$

The equation for line g is given by 5y=2x-20. Suppose line g is parallel to like r and line e is perpendicular to line g. Point

VladimirAG [237]

Sounds as tho' all three lines are parallel. Is that correct?

If so, all three lines have the same slope!

What is the slope of 5y=2x-20 ? Solving for y, y = (2/5)x - 4

The slope is (2/5).

Now find the equation of the line with slope (2/5) that passes thru (10,-8).

It is y - [-8] = (2/5)(x - 10).

We can simplify this, with the result y + 8 = (2/5)x - 4. This, in turn, can be simplified to y + 8 = 2x/5 - 4, or y = 2x/5 - 12. Mult. all terms by 5 to eliminate the fraction:

5y = 2x - 60

Note how this has the exact same form as the given 5y = 2x - 20, EXCEPT that the constant at the end is different.

5y = 2x - 60 and 5y = 2x - 20 are parallel lines with the same slope but different y-intercepts.

Which function has a greater slope and y-intercept than the linear function represented in the table?

Sav [38]

Answer:

B) y=3x+7.5

Step-by-step explanation:

The equation of the data in the table can be obtained by using any two points.

We will use points (3, 13) and (5,17)

The slope - intercept form is:

y = mx + b

We find the slope as:

m = (17-13)/(5-3) = 4/2 = 2

The equation becomes:

y = 2x + b

To find the value of b, the y -intercept is:

13 = 2*3 + b ⇒ b= 13 - 6 = 7

So the equation is:

y = 2x + 7

<h3>Now let's compare this with the options</h3>

A) y = 2x + 8.5

The slope is 2, and y- intercept is 8.5
It has same slope and greater y-intercept
Answer is no

B) y=3x+7.5

The slope is 3, and y- intercept is 7.5
It has greater slope and greater y-intercept
Answer is yes

C) y=5x+6.5

The slope is 5, and y- intercept is 7.5
It has greater slope but smaller y-intercept
Answer is no

D) y=10x+5.5

The slope is 10, and y- intercept is 5.5
It has greater slope but smaller y-intercept
Answer is no
