Given: A water bottle cost 4 dollars and a hat cost 6 dollars.
Let x = Number of water bottles
y = Number of hats
The club wants to raise $1200.
i.e. Required equation : 4x+6y=1200
At x=0,
At x= 300
At x= 240
So,three ordered pairs(x,y) that exist on the line : (0,200), (300,0) and (240,40)
Plot these point on graph and join them.
For every f(x) change the x with the given value.
a.
x³-5x²+6x-4 ..........change the x with 2
(2)³-5(2)²+6(2)-4
8-20+12-4
-4
b.
4x³+3x²+x+2 .... .same here change x to 1
4(1)³+3(1)²+(1)+2
4+3+1+2
10
c.
2x^4-x³+3x²-1 ...........change x as -1
2-(-1)³+3(-1)²-1
2+1+3-1
5
d.
2x³-6x-5 ................change x with -3
2(-3)³-6(-3)-5
2(-27)+18-5
-41
Start dividing this by having 0.0339 over 1.3 then move each decimal over one space. Divide as normal.
Answer
A ratio is a comparison of two quantities by division. Ratios describe a part-to-part comparison or a part-to-whole comparison. Ratios are written three ways: as a fraction, with a colon, and with the word “to.” The ratio for quantity a to quantity b is : a to b, a over b, and a:b
0.00523
10 to the power of 2 equals 100, and 0.523 divided by 100 is 0.00523
