Given:

Radii of two spheres are 3 cm and 4.5 cm  respectively.

Surface  area of the smaller sphere is  367 cm.

To find:

The surface area of the larger sphere.

Solution:

We know that, area of similar spheres is proportional to the square of there radii.

[tex]\dfrac{A_1}{A_2}=\dfrac{(r_1)^2}{(r_2)^2}[/tex]

On substituting the values, we get

[tex]\dfrac{367}{A_2}=\dfrac{(3)^2}{(4.5)^2}[/tex]

[tex]\dfrac{367}{A_2}=\dfrac{9}{20.25}[/tex]

On cross multiplication, we get

[tex](367)(20.25)=9A_2[/tex]

[tex]7431.75=9A_2[/tex]

Divide both sides by 9.

[tex]\dfrac{7431.75}{9}=A_2[/tex]

[tex]825.75 =A_2[/tex]

Therefore, the area of larger sphere is 825.75 cm².

Note: All options are incorrect.

Hi there!

[tex]\large\boxed{0, -\frac{9}{4} }[/tex]

2x - 4y = 9

Begin by isolating the y variable by moving 2x to the right-hand side of the equation. (Subtract 2x from both sides):

2x - 2x - 4y = 9 - 2x

-4y = 9 - 2x

Further isolate by dividing both sides by -4:

-4y / (-4) = (9 - 2x) / (-4)

y = -9/4 - 2x/(-4)

Simplify further:

y = -9/4 + 1/2x

y = 1/2x - 9/4

The "b" value is the y-intercept, therefore:

x = 0 at y = -9/4

Answer:

[tex]\huge\boxed{(0, \frac{-9}{4} )}[/tex]

Step-by-step explanation:

2x - 4y = 9

To find the y-intercept, set the x value in the equation to 0.

Rewrite

2(0) - 4y = 9

Simplify

-4y = 9

Multiply both sides of the equation by -1

4y = 9

Divide both sides of the equation by 4

y = -9/4

y = -4.5

Now that we know the y intercept, we can find the coordinate.

(x, y)

Substitute

(0, [tex]\frac{-9}{4}[/tex])

Step-by-step explanation:

The requirement that side lengths be greater than 0 means that ...

  y > x > 0

  y > z > 0

Then possible values for x and z are 1, 2, 3, and possible values for y are 3, 4, 5, 6, 7.

When we list the possibilities, and exclude those that do not give isosceles triangles, we find the values of {a, b, c} can be those listed above.

Answer:

39 minutes

Step-by-step explanation:

I used a calculator

Answer:

39 minutes

Step-by-step explanation:

a = 0.05m + 3.15 where a=the total charged, m=the amount of minutes

5.10 = 0.05m + 3.15

1.95 = 0.05m

1.95/0.05 = m

m = 39 minutes

Answer:

4m/s²

Step-by-step explanation:

Given that:

Force F is directly proportional to acceleration a

F α a

F = ka

Where k is the constant of proportionality

36 = 6k

Solve for K

36 = 6k

k = 36/6

k = 6

If force = 24 ; acceleration =

24 = ka

k = 6

24 = 6a

a = 24/6

a = 4m/s²

Step-by-step explanation:

Replace everything in the equation that has a x to -3:

f(-3)=3(-3)^2-4(-3)+6

Square the -3:

f(-3)=3(9)-4(-3)+6

Multiply/Distribute

f(-3)=27+12+6

Add:

f(-3)=45

Hope this helps!

Answer:

f(x) = 45

Step-by-step explanation:

f (x) = 3x^2 − 4x + 6 find f (−3)

Replace the variable x with −3 in the expression.

f (−3) = 3(−3)^2 − 4 ⋅ −3 + 6

Simplify 3(−3)^2 − 4 ⋅ −3 + 6

Remove parentheses.

3(−3)^2 − 4 ⋅ −3 + 6

Raise −3 to the power of 2.

3 ⋅ 9 − 4 ⋅ −3 + 6

Multiply 3 by 9.

27 − 4 ⋅ −3 + 6

Multiply −4 by −3.

27 + 12 + 6

Simplify by adding numbers.

Add 27 and 12.

39 + 6

Add 39 and 6.

C) F(x)=1/(x-2)²

Step-by-step explanation:

I'm 100% sure. You can go with it

The solution is Option C.

The value of the equation is f ( x ) = 1/ ( x - 2 )²

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the function be f ( x ) = A

Now , Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k. Vertical asymptotes are defined when the denominator of a rational function tends to zero

So , the function which represents the graph will be

f ( x ) = 1 / ( x - 2 )²   be equation (1)

And , the graph of the function is given below

Hence , the equation is f ( x ) = 1 / ( x - 2 )²

Answer:

Rotation of 180° about the origin, translation of (x + 10, y − 2), and reflection across y = −6

Step-by-step explanation:

The sequence of transformations that will map figure H onto figure H' is the rotation of 180° about the origin, translation of (x + 10, y − 2), and reflection across y = −6.

Given :

Points of Hexagon H  --  (2,2), (2,6), (6,7), (8,6), (8,2), (6,1)

Points of Hexagon H' --  (2,-8), (2,-4), (4,-3), (8,-4), (8,-8), (4,-9)

The following steps can be used to transform the hexagon H into hexagon H':

Step 1 - Translate the hexagon in the positive x-axis direction by a factor of 10.

Step 2 - Translate the graph obtained in the above step by factor 2 in the downward direction.

Step 3 - Now, rotate the graph obtained in the above step 180 degrees about the origin.

Step 4 - Then take the reflection of the graph obtained in the above step about y = -6. The resulting graph shows the graph of Hexagon H'.

Therefore, the correct option is B).
