B. Because the line is negative so it is rise over run meaning down one over two. Then the plus two is the b or y intercept in the equation y= my+b so you would go up two from the (0,0) to start the do the rise over run
Answer:
180 different combinations
Step-by-step explanation:
To find the number of different combinations possible, We first find the number of possibilities for each place, and then multiply all possibilities.
Number of possibilities for president: 5
Number of possibilities for vice-president: 6
Number of possibilities for secretary: 2
Number of possibilities for treasurer: 3
Number of different combinations: 5*6*2*3 = 180
(We can form 180 different groups of 1 president, 1 vice-president, 1 secretary and 1 treasurer)
Answer:
x² -2x +4
Step-by-step explanation:
You recognize the dividend as the sum of two cubes. The factorization of that is ...
... a³ + b³ = (a + b)(a² -ab +b²)
In your problem, you have a=x, b =2, so the factorization is ...
... (x³ +8) = (x +2)(x² -2x +4)
When this is divided by (x +2), the result is (x² -2x +4).
_____
You can also use long division or synthetic division to get the same result.
Answer:
height=24km area of base =11.7km
The formula for volume of a cylinder is V= PI x r^2 x H
r = radius = 1/2 diameter = 1/2*1.8 = 0.9 meters
Height = 25
Volume = PI x 0.9^2 x 25
= PI x 0.81 x 25
= PI x 20.25
= 63.62 cubic meters
