375π litters of water is needed to fill the cylindrical tank with a diameter of 1.0m and height of 1.5m.

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The volume of a cylinder is expressed as;

V = π × r² × h

Where r is radius of the circular base, h is height and π is constant pi.

Given the data in the question;

Plug the given values into the formula above and solve for V, to determine the liters of water that will fill the tank.

V = π × r² × h

V = π × ( 0.5m )² × 1.5m

V = π × 0.25m² × 1.5m

V = 0.375π m³

Next, convert cubic meters to liters.

V = 0.375π m³ = ( 1000 × 0.375π )L

Volume V = 375π L

Therefore, a volume of 375π litters is needed to fill the tank.

Correct option is C, The solution is set of all real numbers.

When x=0, 0=0 and 24 Equals 24 when x = 4.

This equation holds true for all real numbers since both sides of the equation are the same. When 0=0, the solution reveals that the equation is an identity, a specific kind of equation that is true regardless of the value of x.

Identity equations are described as equations that are true regardless of the value of the inserted variable.

Prime factorization is the technique of expressing a number as the product of prime numbers. The only two components in prime numbers are the number itself and the number itself. Prime numbers include, for instance, 2, 3, 5, 7, 11, 13, 17, 19, and so forth. Any number can be represented as a sum of prime numbers by "prime factorizing" it.

Step-by-step explanation:

The intervals on which a quadratic function is positive are those intervals where the function is above the x-axis, i.e. where y > 0.

The zeros of the quadratic function are the points at which the parabola crosses the x-axis.  

If the leading coefficient of a quadratic function is positive, the parabola opens upwards.

If the leading coefficient of a quadratic function is negative, the parabola opens downwards.

Therefore, to find the intervals on which each quadratic function is positive:

Given function:

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

Factor the given function:

[tex]\implies y= x^2+4x-2x-8[/tex]

[tex]\implies y=x(x+4)-2(x+4)[/tex]

[tex]\implies y=(x-2)(x+4)[/tex]

Substitute y = 0 to find the zeros:

[tex]\implies (x-2)(x+4)=0[/tex]

[tex]\implies x-2=0 \implies x=2[/tex]

[tex]\implies x+4=0 \implies x=-4[/tex]

The leading coefficient is positive, so the parabola opens upwards.  

Therefore, the interval on which the function is positive is:

Given function:

[tex]y=-x^2+4x+12[/tex]

Factor the given function:

[tex]\implies y=-(x^2-4x-12)[/tex]

[tex]\implies y=-(x^2-6x+2x-12)[/tex]

[tex]\implies y=-(x(x-6)+2(x-6))[/tex]

[tex]\implies y=-(x+2)(x-6)[/tex]

Substitute y = 0 to find the zeros:

[tex]\implies -(x+2)(x-6)=0[/tex]

[tex]\implies (x+2)(x-6)=0[/tex]

[tex]\implies x+2=0 \implies x=-2[/tex]

[tex]\implies x-6=0 \implies x=6[/tex]

The leading coefficient is negative, so the parabola opens downwards.  

Therefore, the interval on which the function is positive is:

Given function:

[tex]y=5x^2-3x-8[/tex]

Factor the given function:

[tex]\implies y=5x^2-8x+5x-8[/tex]

[tex]\implies y=x(5x-8)+1(5x-8)[/tex]

[tex]\implies y=(x+1)(5x-8)[/tex]

Substitute y = 0 to find the zeros:

[tex]\implies (x+1)(5x-8)=0[/tex]

[tex]\implies x+1=0 \implies x=-1[/tex]

[tex]\implies 5x-8=0 \implies x=\dfrac{8}{5}[/tex]

The leading coefficient is positive, so the parabola opens upwards.  

Therefore, the interval on which the function is positive is:

Angle of incidence Equals Angle of reflection, according to the physics principle of reflection.

Both angles  ( θ) are equal, as seen in the attached image.

Answer:

X = 31

Step-by-step explanation:

180 = 2x + 9 + 3x +16

180 = 5x + 25

180 + -25 = 5x

155 = 5x

5x/5 = 0 (Cancel out)

155 /5x = 31

X = 31

Check math by :

2 x 31 = 62 + 9 = 71

3 x 31 = 93 + 16 = 109

109 + 71 = 180

Therefore, X = 31

Therfore we can derive the equation:
