Answer:

A = 28.26

C = 18.84

Step-by-step explanation:

A = [tex]\pi r^{2}[/tex]

C = 2[tex]\pi r[/tex]

A = 3.14 x 3 x 3 = 28.26

C = 2 x 3.14 x 3 = 18.84

Answer:

Step-by-step explanation:

In verse variation would be 3  = k / 2.4   so k  = 7.2

So we have  y = 7.2 / 5  = 1.44

Answer is 1.44.

Answer:

Hence, the value of y is:

1.44

Step-by-step explanation:

It is given that:

The pair of points is on the graph of an inverse variation.

(2.4, 3) and (5, y)

We have to find the missing value y in the point.

As we know that in the inverse variation the value of y is the inverse value of x by some k.

i.e. in first point (2.4,3) let 'k' be a number such that:

Hence, the inverse is k=7.2

Now in the second point (5,y) we find the value of y as:

Hence, the value of y is:

1.44

Variation can be direct, inverse, joint or combined.

The missing value of y is (b) 1.44

The points are said to represent inverse variation.

So, we have:

[tex]x_1 \times y_1 = x_2 \times y_2[/tex]

Substitute x and y values in the equation

[tex]2.4 \times 3 = 5\times y_2[/tex]

Multiply 2.4 and 3

[tex]7.2= 5\times y_2[/tex]

Divide both sides by 5

[tex]1.44 = y_2[/tex]

Rewrite as:

[tex]y_2 = 1.44[/tex]

Hence, the missing value of y is (b) 1.44

Step-by-step explanation:

The square root of 9 is 3, while the square root of 4 is 2

3 x 2 = 6

So

A is true

B is true

C is true because we can multiply the two terms of the root and mantain the same root. In fact √36 = 6

D is wrong because the result of the expression is not 6

E is wrong for the same reason of D

Answer:

648 cm³

Step-by-step explanation:

For Cuboid

l = 12cm

b = 9cm

h = 6cm

Now, The volume of a cube is

l × b × h

12 × 9 × 6 cm

108 × 6 cm

648 cm³

Thus, The volume of a cuboid 12cm long 9 sm broad and 6 cm high is 648 cm³

Answer:

Step-by-step explanation:2 one

Answer:

A=368 miles

B= 356.3 miles

Step-by-step explanation:

Given data

Let the two trains be A and B

A+B=724.3----------1

A-B=11.7--------------2

From eqn 1

A= 724.3-B

put this in place of A in eqn 2

724.3-B-B= 11.7

724.3-2B= 11.7

724.3-11.7= 2B

712.6=2B

B= 712.6/2

B= 356.3 miles

Put B=356.3 in eqn 1

A+356.3=724.3----------1

A= 724.3-356.3

A=368 miles

hello

i think so...

hope it helps

have a nice day

P1(x) - P2(x) = -0.01x² + 4x + 200

This shows that P1(x) profit is less than P2(x).

P2(x) - P1x = 0.01x² - 4x - 200

This shows that P2(x) profit is more than P1(x).

Polynomial is an equation written as the sum of terms of the form kx^n.

where k and n are positive integers.

We have,

Plant 1:

P1 (x) = -0.03x² + 25x - 1500

Plant 2:

P2 (x) = -0.02x² + 21x - 1700

P1(x) - P2(x):

= -0.03x² + 25x - 1500 - (-0.02x² + 21x - 1700)

= -0.03x² + 25x - 1500 + 0.02x² - 21x + 1700

= -0.01x² + 4x + 200

For any x value, we will get a negative value.

This means,

P1(x) profit is less than P2(x).

P2(x) - P1x:

= -0.02x² + 21x - 1700 - (-0.03x² + 25x - 1500)

= -0.02x² + 21x - 1700 + 0.03x² - 25x + 1500

= 0.01x² - 4x - 200

For any x value, we will get a positive value.

This means,

P2(x) profit is more than P1(x).

Thus,

P1(x) - P2(x) shows that P1(x) profit is less than P2(x).

P2(x) - P1x shows that P2(x) profit is more than P1(x).
