Answer: C. The lines intersect but are not perpendicular.

Step-by-step explanation:

The correct option is C, the lines intersect but are not perpendicular.

To determine which statement is true about the two lines whose equations are given below:

y = 3x + 2

y = -4x + 9

We can compare the slopes of the two lines. The slopes of these lines are 3 and -4 respectively.

Two lines are parallel if and only if their slopes are equal. Since the slopes of these lines are not equal, we can eliminate options A.

Two lines are perpendicular if and only if the product of their slopes is -1. The product of the slopes of these lines is -12, which is not equal to -1. Hence, we can eliminate options B.

Since the lines are neither parallel nor perpendicular, they intersect. To determine whether they intersect perpendicularly, we can compute the angle between them using the slopes.

The angle between two lines is given by the formula:

[tex]tan \theta = \dfrac{(m_2 - m_1)}{ (1 + m_1m+_2)}[/tex]

where m₁ and m₂ are the slopes of the two lines.

Substituting the slopes of the given lines, we get:

[tex]tan \theta = \dfrac{|(-4 - 3)} { (1 + (3 \times -4))|} \\[/tex]

tanθ = 7 / 11

Therefore, the correct option is C: the lines intersect but are not perpendicular.

Step-by-step explanation:

domain is x numbers and that has all the x numbers in it

The value of domain in the given function is ( -4, 0 , 1, 2).

The value of range in the given function is ( 1, -3, -4 ).

Given,The function {(0,1), (1,-3), (2,-4), (-4,1)}

We have to find ,

Domain and range of the given function .

The domain of a function is the complete set of possible values of the independent variable.

So, The value of domain in the given function is ,

Domain = ( -4, 0, 1,  2 )

And, The range of a function is the complete set of all possible resulting values of they,  dependent variable (usually), after we have substituted the domain.

So, The value of range in the given function is

the area of the yellow figure is 45 square units.

The figure shaded in yellow can be decomposed in two simpler ones, a triangle of base of 4 units and height of 5 units, and a rectangle of 5 units by 7 units.

The area of the triangle is:

A = 4*5/2 = 10 square units

The area of the rectangle is:

A' = 5*7 = 35 square units.

Adding that we get:

A + A' = 10 square units + 35 square units = 45 square units.

Then the area of the yellow figure is 45 square units.

Answer:

After 3 hours there is left 22.5 grams of radioactive material.

Step-by-step explanation:

We can calculate the mass of radioactive material remaining after 3 hours, by using the decay equation:           

[tex]N_{t} = N_{0}*e^{-\lambda t}[/tex]     (1)

Where:

[tex]N_{0}[/tex]: is the initial mass = 180 g

[tex]N_{t}[/tex]: is the remaining mass after time t

λ: is the decay constant

The decay constant is given by:

[tex] \lambda = \frac{ln(2)}{t_{1/2}} [/tex]

Where [tex]t_{1/2}[/tex] = 1 h.

By entering λ into equation (1) we hve:

[tex] N_{t} = N_{0}*e^{-\frac{ln(2)}{t_{1/2}} t} [/tex]

[tex] N_{t} = 180 g*e^{-\frac{ln(2)}{1 h} 3 h} = 22.5 g [/tex]

Therefore, after 3 hours there is left 22.5 grams of radioactive material.

The value of d is 2.

We are provided with the following equation,

4 + d = 6                                    

We are supposed to find the value of d in the above equation.

To solve the equation we need to apply basic mathematical operations. The steps that need to be followed to simply this equation are mentioned below,

4 + d = 6

To get the value of d we need to subtract 4 from both the sides of this equation. On substracting  4 from both the sides of this equation, we will get

4 + d - 4  = 6 - 4

⇒ d = 6 - 4

⇒ d = 2

Thus, the value of d in the equation 4 + d = 6 is 2.

The length of the hypotenuse is 5.426 meter

Let the two shorter sides of the right angles triangle be denoted as x meters.

The formula for the area of right triangle is given as,

                     A = ab/2

  Where, a and b are the length of the shorter sides of the triangle

Also we have been given the area of the triangle which is 7.36 sq. meter

Thus ,    A = 7.36

             x^2/2 = 7.36

              x^2 = 14.72

                x = 3.84

Now according to the Pythagoras theorem,

   H = √P^2 + B^2

Where,  H = hypotenuse

               P = perpendicular

              B = base

Now putting the required values we get

    H = √x^2 + x^2

        = √2x^2

        = x√2

       = 5.426 meter

Hence the length of the hypotenuse is 5.426 meter
