An atom has a diameter of 2.00 Å and the nucleus of that atom has a diameter of 9.50×10−5 Å . Determine the fraction of the volume of the atom that is taken up by the nucleus. Assume the atom and the nucleus are a sphere.

18 units is the distance between points F and G.

Assume a line with points marked on it.

Center is 0.

Left to the point 0 indicates negative numbers.

Right to the point 0 indicates positive numbers.

Given,

A number line is marked with negative 10 to positive 14.

Point F is placed at negative 6.

Point G is placed at positive 12.

We have to determine the distance between points F and G.

We can consider the number line.

From 0 to negative 10 there were 10 units.

From 0 to positive 14 there were 14 units.

Now points F and G,

From 0 to negative 6 there were 6 units.

From 0 to positive 12 there were 12 units.

We can add this together:

That is,

6 units + 12 units = 18 units.

Therefore, the distance between points F and G is 18 units.

t = 100 shirts are in the box

Plug this into the equation and simplify to find W

W = 250+132.5t

W = 250+132.5(100)

W = 250+13250

W = 13500

The ticket price of

A Senior citizen = $14

A Child               = $4

First day of ticket sales :

Senior citizen tickets (s) = 14

Child tickets (c)             = 14

Total price of both tickets = $252

14s + 14c = 252   eq. (1)

Second day of ticket sales :

Senior citizen tickets (s) = 9

Child tickets (c)              = 7

Total price of both tickets = $154

9s + 7c = 154   eq. (2)

Multiplying equation 2 with 2, we get

18s + 14c = 308    eq. (3)

Now, we will subtract eq. (1) from eq. (3)

18s + 14c = 308    eq. (3)

-14s - 14c = -252    eq. (1)

____________________

          4s = 56

            s = 56/4

            s = 14

We get the ticket price of one senior citizen which is 14 Dollars.  

Now, we will put s = 14 in eq. 2,

So,  9s + 7c = 154

 (9×14) + 7c = 154

              7c = 154  - 126

                c = 28 / 7

               c = 4

Ticket price of one child is 4 Dollars.

Hence, the ticket price of a senior citizen and a child is $14 and $4, respectively.

The  transformations that is possible in a linear function is: g(x) = (x - 3)².

if the function of the g (x) is known to be the original function, then one can say that:

g(x) = (x - 3)²

= g(x) = x²

This is one that is shifted by 3 unit to the right because in the above, one need to substitute x for x - 3.

Hence , it functional graph can be said to be a parabola with a vertices that is known to be opening at (3,0)

The given triangle whose sides are 6cm, 10cm, and 12cm is an obtuse triangle and it can be determined by using Pythagorean theorem which is the correct option (C).

Pythagoras theorem states that a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

The given triangle whose sides are 6cm, 10cm, and 12cm

Now, applying Pythagorean's theorem:

⇒ 6² + 10² = 12²

⇒ 36 +100 = 144

⇒ 136 = 144

Here, it is clearly observed that 136 <  144 therefore, the triangle is obtuse.

Answer:

f(0) = 0

f(-2) = 0

f(5) = 15

f(-10) = 16

Step-by-step explanation:

Piecewise functions have multiple pieces of curves/lines where each piece corresponds to its definition over an interval.

Given piecewise function:

[tex]f(x)=\begin{cases} \begin{aligned}-2x-4 & \;\;\textsf {if }\;x < 0\\3x & \;\;\textsf {if }\;x\geq 0\\\end{aligned}\end{cases}[/tex]

Therefore, the function has two definitions:

When graphing piecewise functions:

First piece of the function

Substitute zero into the first function:

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

Place an open circle at point (0, -4).

To help graph the line, find another point on the line by inputting another value of x that is less than zero into the same function:

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

Place point (-2, 0) and draw a straight line from the open circle at (0, -4) through (-2, 0).  Add an arrow at the other endpoint to show it continues indefinitely as x → -∞.

Second piece of the function

Substitute zero into the second function:

[tex]\implies f(0)=3(0)=0[/tex]

Place an closed circle at point (0, 0).

Again, to help graph the line, find another point on the line by inputting another value of x that is more than zero into the same function:

[tex]\implies f(2)=3(2)=6[/tex]

Place point (2, 6) and draw a straight line from the closed circle at (0, 0) through (2, 6).  Add an arrow at the other endpoint to show it continues indefinitely as x → ∞.

See attached for graph.

To find the given functions, decide which function to use based on the given value of x, then solve.

f(0) means to find the value of the function when x = 0.

Therefore, input x = 0 into the second function as x ≥ 0.

[tex]\implies f(0)=3(0)=0[/tex]

f(-2) means to find the value of the function when x = -2.

Therefore, input x = -2 into the first function as x < 0.

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

f(5) means to find the value of the function when x = 5.

Therefore, input x = 5 into the second function as x ≥ 0.

[tex]\implies f(5)=3(5)=15[/tex]

f(-10) means to find the value of the function when x = -10.

Therefore, input x = -10 into the first function as x < 0.

[tex]\implies f(-10)=-2(-10)-4=16[/tex]

the algae that is present with the scientist to research upon covers a surface area of 2004 inches² in the rectangular prism.

The dimensions of the rectangular prism is given by:

Height = h = 18 inches

Width = w = 14 inches

Length = l = 30 inches

Now, we have to calculate the surface area of the tank excluding the top of the tank to find out how much algae has been present there for the scientist to test.

So, the formula for surface area will become:

A = 2(w l + h l + h w) - l w ( as the top has to be excluded)

Now substituting the values of l, w and h, we get that:

A = 2 [ (14) (30) + (18) (30) + (18) (14) ] - (30) (14) inches²

A = 2 [ 420 + 540 + 252 ] - 420 inches²

A = 2 [ 1212 ] - 420 inches²

A = 2424 - 420 inches²

A = 2004 inches²

Therefore, we get that, the algae that is present with the scientist to research upon covers a surface area of 2004 inches² in the rectangular prism.

The polynomial function of least degree with only real coefficients is y = x³ - 8 · x² + 22 · x - 20.

The statement indicates that the polynomial has a leading coefficient of 1 and zeros of 2 and 3 + i. By algebra of quadratic equations, equations with real coefficients with complex roots are α + i β and α - i β. Then, all the roots of the polynomial function of least degree are 2, 3 + i and 3 - i. The complete expression is shown below:

y = 1 · (x - 2) · (x - 3 - i) · (x - 3 + i)

y = (x - 2) · [x² - 3 · x - i · x - 3 · x + i · x + (3 + i) · (3 - i)]

y = (x - 2) · (x² - 6 · x + 9 - i²)

y = (x - 2) · (x² - 6 · x + 10)

y = x³ - 6 · x² + 10 · x - 2 · x² + 12 · x - 20
