Answer:
C. Hyperbola opening up and down
Step-by-step explanation:
A graph tells the tale.
___
The term with the positive coefficient identifies the axis along which the hyperbola opens. Here, that is the y-axis, so the figure opens up and down.
The minus sign between the squared terms indicates it is a hyperbola, rather than a closed curve (ellipse or circle). The fact that both terms are squared indicates it is <em>not</em> a parabola.
Here are the steps to solving:
1) Write out problem 3.6+7.2k <25.2
2) Subtract 3.6 7.2k <21.6
3) Divide by 7.2 k <3
So k<3 would be your answer
Volume of cylinder is 402.1238....=402.12ft
Volume of rectangle is 1344ft
Add both together= 1746.12ft
Surface area of rectangle:
Length=14ft
width= 8ft
height =12ft
14x12=168x2=336
8x12=96x2=192
14x8=112x2=224
336+192+224=752
Surface Area of cylinder:
Radius= 4ft
height=8ft
2π r h+2π r^2
2π4(12)+2<span>π4^2
2</span>π48+2<span>π16
301.59+100.53=402.42ft
Add both surface area together=1154.12ft</span>
Answer:
part one:
6 3
22 1
30 0
part two:
0.50*s+4*a=15
Step-by-step explanation:
part one:
firstly:
6 individual songs cost 6*0.50= 3 dollars
she has 15 dollars so after downloading 6 individual songs that cost 3 dollars together
it means that she has only 15-3=12 dollars to download full albums
so 12/4=3 albums
because 4 dollar cost one album and with 12 dollars she can buy just 3 albums
secondary:
she downloaded 1 album
and one album cost 1*4=4 dollars
she has 15 dollars ,after buying 1 album
she has 15-4=11 dollars
so she can download 11/0.50=22 individual songs
so she can download 22 individual songs.
the last one:
she downloaded 30 individual songs
that all together cost 30*0.50=15 dollars
but she has 15 dollars at all so she cant buy any album because she spent all her money in individual songs.
because 15-15=0 money left
part two:equation
0.50*s+4*a=15
