If A = (2, 4, 6, 8, 10) and B = {4, 8, 10), then which of the following statements is false? ​

Answer:

84

Step-by-step explanation:

1/4 of class don't play basketball but do play volleyball

so 9/28 of class play both since 4/7 - 1/4 = 9/28

9/28 of class = 27

1/28 of class = 3

class = 3*28

There are 84 girls in the class.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Girls who plays basketball = (3/4)x

Girls who plays volleyball = (4/7)x

Girls who plays both games = 27

Now, Let us consider total girls in the class = x

So we can write it as mathematical equation as;

⇒ (3/4)x +(4/7)x - 27 = x

By taking L.C.M. -

⇒ (21x+16x)/28 - (27) = x

⇒ 37x/28 = x + 27

⇒ 37x = 28x + (27×28)

⇒ 9x = 27×28

⇒ x = (27×28)/9

⇒ x = 3×28

⇒ x = 84

So, There are total 84 girls in the class.

The factor of the equation 4x² + 12x + 9 is 2x+3. Then the correct option is A.

It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

The factor of the polynomial is calculated as:-

4x² + 12x + 9 = 4x² + 6x + 6x + 9

                     = 2x ( 2x + 3 ) + 3 ( 2x + 3 )

                     = (2x + 3)(2x + 3)

The factor is (2x + 3). Hence, the correct option is A.

Answer:

p1 = 70 deer

p2 = 98 deer

Step-by-step explanation:

We use the population growth expression:

[tex]N(t)=N_0\,(1+r)^t[/tex]

which in our case renders:

[tex]N(t)=N_0\,(1+r)^t\\N(t)=50\,(1+0.4) ^t\\N(t)=50\,(1.4) ^t[/tex]

Therefore, after 1 year the population would be:

[tex]N(1)=50\,(1.4) ^1=70[/tex]

giving a total of 70 deer

and after two years, it would be:

[tex]N(2)=50\,(1.4) ^2=98[/tex]

Answer: Bottom left

5x5x5=125

The volume having 125 cubic, is a box which has dimensions,  5 feet, 5 feet, 5 feet. So Option D is correct

In mathematics, Space occupied by three dimensional objects is called Volume. Basically it is a space within a closed region of every three dimensional object.

Given that,

4 boxes having different different dimensions

1. 4 feet, 9 feet, 5 feet

2. 4 feet, 3 feet, 4 feet

3. 5 feet, 12 feet, 2 feet

4. 5 feet, 5 feet, 5 feet

lets calculate the volume for all the four boxes

V = 4 feet  × 9 feet  × 5 feet  = 180  feet³

V = 4 feet × 3 feet × 4 feet  = 48 feet³

V =  5 feet × 12 feet × 2 feet  = 120 feet³

V =  5 feet × 5 feet × 5 feet  = 125  feet³

Hence, the volume of box having dimension 5 feet, 5 feet, 5 feet is 125  feet³

Answer:

Step-by-step explanation:

Mulriplying the first equation by 2 yields -10x+2y=-12.

Subtracting the second equation from this gives -17x=-51, and thus x=3.

Substituting this back into the first equation gives -15+y=-6, and thus y=9.

Answer:

Step-by-step explanation:

I think you have the question incomplete, and that this is the complete question

sin^4a + cos^4a = 1 - 2sin^2a.cos^2a

To do this, we can start my mirroring the equation.

x² + y² = (x + y)² - 2xy,

This helps us break down the power from 4 to 2, so that we have

(sin²a)² + (cos²a)² = (sin²a + cos²a) ² - 2(sin²a) (cos²a)

Recall from identity that

Sin²Φ + cos²Φ = 1, so therefore

(sin²a)² + (cos²a)² = 1² - 2(sin²a) (cos²a)

On expanding the power and the brackets, we find that we have the equation proved.

sin^4a + cos^4a = 1 - 2sin^2a.cos^2a
