Answer:
A. f(x)=9x+4
Step-by-step explanation:
Function is f(x) =9x+4, because if x=1, then f(1)=9*1+4=9+4=13;
if x=5,then f(5)=9*5+4=45+4=49
I am sorry but it is just an example !
Question ) A university has 30,330 students. In a random sample of 270 students, 18 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answer ) 2,022 students will speak three or more languages
Here's why:
Using proportions.
18. x
--- =. ----
270. 30,330
Cross multiply
18 x 30,330 = 545,940
270 multiply x = 270x
545,940 divided by 270 = 2,022
x = 2,022 students
Step-by-step explanation:
Because it is 5 units to the left of 1 on a horizontal number line
9514 1404 393
Answer:
720°
Step-by-step explanation:
The formula for the sum of interior angles of a convex n-gon is ...
angle sum = 180°(n -2)
This hexagon will have an angle sum of ...
angle sum = 180°(6 -2)
angle sum = 720°
_____
<em>Additional comment</em>
Essentially, the formula is telling you that the figure can be divided into 4 triangles, each of which has an angle sum of 180°. If you like, you can consider that a diagonal between opposite vertices will divide the figure into two quadrilaterals, each with an angle sum of 360°.
<span>As we know that, volume of a cylinder is given by expression, 3.142 * height *(radius)^2
As all the units are in feet
i.e. 3.142 * 65 * 4 = 816.92
Hence, correct answer is C</span>
