Answer:
Step-by-step explanation:
formula for cylinder:V=πr2h
shape of the base: circle
formula for circle: A=πr2
radius: 6.5cm
height: 16cm
V=3.14x6.5^2x16
2122.64cm^3
It seems you just keep adding 3
-2; 1; 4; 7; 10; 13; 16; 19; 22; 25; 28; 31; 34; 37
37 is the fourteenth term.
Answer:
The number of ways in which students were chosen is 45 ways .
Step-by-step explanation:
Given as :
The number of students in a class = x = 10
The number of students chosen by teacher to go to library = y = 2
Let The number of ways in which students were chosen = n ways
<u>Now, According to question</u>
So, number of ways in which students were chosen = 
Or, n ways = 
Or, n = 
Or, n = 
Or, n = 
Or, n = 
Or, n = 5 × 9
i.e n = 45
So, The number of ways in which students were chosen = n = 45 ways
Hence,The number of ways in which students were chosen is 45 ways . Answer
Answer:
84.26° in the south west direction.
Step-by-step explanation:
I've attached an image showing the triangle formed by the motion of the plane and the wind.
I've depicted the plane being pushed west and the wind moving south west.
Thus, the direction of motion of the plane will be angle θ.
Using trigonometric ratios;
25/250 = cos θ
cos θ = 0.1
θ = cos^(-1) 0.1
θ = 84.26°
Thus will be in the south west direction.
Answer:
-4/3
Step-by-step explanation:
Slope is Rise over run. So you take y2-y1 over x2-x1.
in this case, the two points are (2,-1) and (-1,3).
<u>3--1</u>
-1-2
You get 4 over -3, which gives you a slope of -4/3
