Answer:

B

Step-by-step explanation:

The cylindrical part

Area of the cylindrical part = Circumference of the circle * height

Area of the cylindrical part = pi * d * height

Area = 3.14 * 10 * 9

Area =                                                                                282.6

Lid

Area = pi * r^2

r = 5

Area = 3.14* 5^2 * 2

Area =                                                                         <u>         157</u>

Total                                                                                    439.6                                                                        

I know this doesn't look right according to the diagram, but it is the only way that you can solve the question. That is, you must assume there are two lids, not one as the diagram suggests.

Is (0,0) a solution of the system y&gt;x and x+y&gt;0?
olga55 [171]
Plug the values (x,y)=(0,0) into the inequalities:

y\ \textgreater \ x \\&#10;0\ \textgreater \ 0 \\&#10;not \ true \\ \\&#10;x+y\ \textgreater \ 0 \\&#10;0+0\ \textgreater \ 0 \\&#10;0\ \textgreater \ 0 \\&#10;not \ true

0 isn't greater than 0, no (0,0) is not a solution to either of these inequalities.

The answer is D.

Help me iv been trying from this morning

Answer:

i did the first

Step-by-step explanation:

1st way

Standard form: a(X-h)²+k = ( -2/3X² -16/3X -32/3) +32/3 -17/3 = -2/3(X +4)² +5

y = -2/3*X^2-16/3*X-17/3

X = -4 ±√( 15/2) = -6.7386, or -1.2614

Axis of symmetry: X= -4; Vertex (maximum)=(h,k)=( -4, 5); y-intercept is (0,-5.66666666667)

two real roots: X=-1.2613872124776866 and -6.738612787477313
