Solve the quadratic function by completing the square -32 = 2(x+ + 10x)
-32 +
= 2(x+ + 10x + 25)
18 = 2(x + 5)2
9 = (x + 5)2
= x + 5
+
x= -2 orx =

The volume of a cylinder, found using 3.14 to approximate pi, is 50,240 cm3. The radius of the cylinder is 40 cm.What is the height of the cylinder?

Express your answer as a whole number.

_____cm

Answers

V = pi * r^2 * h

Plug in what we know:

50240 = 3.14 * 40^2 * h

Simplify the exponent:

50240 = 3.14 * 1600 * h

Multiply:

50240 = 5024h

Divide 5024 to both sides:

h = 10
50,240 / 80 (I got 80 from doing 40 times 2)
that is 628
628/3.14
that is 200
the height is 200 cm

H+9.7=-9.7

how would I show work for this

Answers

H+9.7=-9.7\ \ \ |subtract\ 9.7\ from\ both\ sides\n\nH+9.7-9.7=-9.7-9.7\n\nH=-(9.7+9.7)\n\n\boxed{H=-19.4}

an outdoor swimming pool cost $8 per day to visit during the summer there is also a $25 yearly registration fee is the total cost proportional to the total number of days visited

Answers

No. a proportional relationship has to cross the origin and with the added $25 registration fee the answer would not cross the origin. you can also tell by the linear equation it it was proportional the equation would either be y=mx+0 or just y+mx when m is y divided by x but your equation is y= 8x+25

Can someone help please? :)A storage tank holds 235,500 in3 of a chemical. The chemical is dispensed to completely fill 25 identical cylindrical containers, each with a radius of 5 in. What is the height of the cylindrical containers? Use 3.14 to approximate pi.

Answers

Vtotal=25 times volume of each small cylinder

find volume of each cylinder small
V=hpir^2
r=5
V=hpi5^2
v=hpi25
use 3.14 for pi
V=78.5h

Vtotal=25 times vsmal contanier

25 of these
mulitly volume by 25
78.5h times 25=1962.5h

235500=1962.5h
divide both sides by 1962.5
120=h
the height of each cylnder was 120 inches or 10 feet

Margo is freezing 8 cups of strawberry of this is two thirds the total strawberries that were picked how many cups of strawberry did Margo pick?

Answers

To figure out the answer to this problem you have to divide 8 by 2/3 in order to divide with fractions you have to flip the fraction and multiply so instead of 8 divided by 2/3 it will be 8 times 3/2. Once you multiply that you get 12/1 or 12 as your answer.
