Answers

Answer 1

Answer:

2x^2

Step-by-step explanation:

I would just multiply the x by 2 before adding the exponent

Answer 2

2x^2 is right because u double the size and keep the exponent

The surface area of a lantern shaped like a sphere is 452.16 square inches. What is the approximate volume of the lantern? Use 3.14 for π. Round your answer to the nearest hundredth.
A.150.72 in.3
B.452.16 in.3
C904.32 in.3
D.5,425.92 in.3

Answers

I think the answer is C 904.32 in.3

The approximate volume of the lantern is, V = 904.32 in³

How can the surface area of this sphere can be expressed ?

The concept here is using the surface area formula which is

A = Area = (4 π r² )

V= Volume =( 4/3 π r³)

Then , We get;

A / V = 3 / r

Also, r = √A / 4π

Then we can substitute the values as

π = 3.14

r = √452.16 / 4×3.14

r = √36

r = 6

Hence, We get;

V = 4/3 πr³

V = 4/3 × 3.14 × 6³

V = 904.32 in³

Answer:

Circumference formula:

C = πd

π is the constant and π = 3.14

A) C = 3.14*3 cm = 9.42 cmB) C = 3.14*10 = 31.40 cmC) d = 24/3.14 = 7.64 cmD) d = 18/3.14 = 5.73 cmE.) C = 3.14*1 = 3.14 cm

Answer:

Círclє Díαmєtєr Círcumfєrєncє

( A ). 3 cm 9.42 cm

( B ). 10 cm 31.40 cm

( C ). 7.64 cm 24 cm

( D ). 5.73 cm 18 cm

( E ). 1 cm 3.14 cm.

Step-by-step explanation:

Formula used

◈ Circumference of circle = π × diameter

◈ Diameter of circle = Circumference of circle / π

Solution

usíng vαluє σf π = 3.14

( A ) Díαmєtєr = 3 cm

Círcumfєrєncє = 3.14 × 3 = 9.42 cm.

( B ) Díαmєtєr = 10 cm

Círcumfєrєncє = 3.14 × 10 cm = 31.40 cm.

( C ) Círcumfєrєncє = 24 cm

Díαmєtєr = 24 / 3.14 cm = 7.64 cm.

( D ) Círcumfєrєncє = 18 cm

Díαmєtєr = 18 /3.14 = 5.73 cm.

( E ) Díαmєtєr = 1 cm

Círcumfєrєncє = 3.14 × 1 cm = 3.14 cm.

Answers

Answer:

Step-by-step explanation:

sir in the graph every point is (X,Y) so you should choose consecutive random numbers for the X values for the first point after that put the values you choose In the equations so now you have just numbers in the equation .. add, subtract and multiply at the end you will get a value .. ok this Y for the first point .. mark this point on the graph and continued this process until it reached at least 3 points, and connected between them.

Note : do this with each equation separately and do not connecte between two points for two different equations

the equation with x will become as line

the equation with x² will become as arch

after you finsh drwaing see the points that the tow equation are touching within and write them. Usually it is two points

Step-by-step explanation:

First, set the equations as equal to eachother because both equal y:

[tex]x^2-6x-7=x+1[/tex]

Now, solve to get everything on one side of the equation so that the other side of the equation is set to 0:

[tex]x^2-7x-8=0[/tex]

Now use the sum product pattern:

[tex]x^2+x-8x-8[/tex]

(as you can see, the above equation is equivalent to the previous equation, but there are now four values instead of three)

Now take the common factor from the two pairs:

[tex]x(x+1)-8(x+1)[/tex]

Rewrite in factored form:

[tex](x-8)(x+1)[/tex]

Now to get both values of x, set each factored equation to 0 and solve for x (becuase remember, the equation still equals 0):

[tex](x-8)=0\\x=8[/tex]

[tex](x+1)=0\\x=-1[/tex]

NOW that we have both values of x, we can subsitute them into EITHER equation and solve to get the corresponding y values:

[tex]y=(8)+1\\y=9[/tex]

[tex]y=(-1)+1\\y=0[/tex]

So that's how we solve to get these coordinates: (8,9) & (-1,0).

Good luck on your final and I hope I was able to help :)
