Using an exponential function, it is found that:

a) The model is: [tex]A(t) = 30000(1.05)^t[/tex]

b) Her predicted profit is of $62,368.

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

Item a:

Then:

[tex]A(t) = A(0)(1 + r)^t[/tex]

[tex]A(t) = 30000(1 + 0.05)^t[/tex]

[tex]A(t) = 30000(1.05)^t[/tex]

Item b:

[tex]A(15) = 30000(1.05)^{15} = 62368[/tex]

Her predicted profit is of $62,368.

Answer:

[tex]\huge\boxed{318yd^2}[/tex]

Step-by-step explanation:

The object shown in the diagram is a triangular prism, which contains two triangular sides and three rectangular sides.

The area of a triangle is simply [tex]\frac{bh}{2}[/tex].

Because the triangles are both the same, you may multiply the equation by 2 to get simply bh, or 9 * 6, or 54.  

Then, simply solve for the areas of each rectangle:

r1 = 11 * 7 = 77

r2 = 11 * 8 = 88

r3 = 11 * 9 = 99.

Then, simply add all the values to get:

99 + 88 + 77 + 54

318.

Answer:

The first set is a solution, the second is not.

Step-by-step explanation:

Testing by filling in the numbers into the equation:

(1, 1.5): x=1, y=1.5

⇒ 1.5 =? [tex]\frac{1}{4}[/tex] · 1 + [tex]\frac{5}{4}[/tex]

⇒ 1.5 =? [tex]\frac{1}{4}[/tex] + [tex]\frac{5}{4}[/tex]

⇒ 1.5 =? [tex]\frac{6}{4}[/tex]

⇒ 1.5 =? 1.5  ⇒ Correct: is indeed solution to the equation

(12, 4): x=12, y=4

⇒ 4 =? [tex]\frac{1}{4}[/tex] · 12 + [tex]\frac{5}{4}[/tex]

⇒ 4 =? [tex]\frac{12}{4}[/tex]  + [tex]\frac{5}{4}[/tex]

⇒ 4 =? [tex]\frac{17}{4}[/tex] ⇒ Incorrect: this is not a solution for the equation

Nuclear reaction involves the disintegration of an element and emission of radioactive particles during the process. This process can be natural, or artificially induced. Thus, the equation for the reaction is balanced.

Nuclear reaction is the process in which a given element emits radioactive particles or radiation. The two classes are: natural transmutation and artificial transmutation.

Natural transmutation occurs on its own due to the half life of the element. While artificial transmutation involves inducing or bombarding an element with another element or particle.

In the given question, the radon element undergoes transmutation into polonium and an alpha particle. The equation is given as;

[tex]^{219} _{86} RN[/tex] ⇒  [tex]^{215} _{84} Po[/tex] + [tex]^{4} _{2} a[/tex]

Therefore, the equation is balanced since an alpha particle was emitted.

Answer: [tex]2x^{2} + 5x -3[/tex]

Step-by-step explanation:

Find the quotient of  [tex]\frac{16x^4+40x^3-24x^2}{8x^2}[/tex]

Step 1: Break down the polynomial equation

[tex]\frac{16x^4}{8x^2}[/tex] + [tex]\frac{40x^3}{8x^2}[/tex] - [tex]\frac{24x^2}{8x^2}[/tex]

Step 2: Divide each piece by dividing the coeffients and subtracting the variables.

16 ÷ 8 = 2

[tex]x^{4}[/tex] - [tex]x^{2}[/tex] = [tex]x^{2}[/tex] → 2[tex]x^{2}[/tex]

40 ÷ 8 = 5

[tex]x^{3}[/tex] - [tex]x^{2}[/tex] = [tex]x[/tex] → 5[tex]x[/tex]

- 24 ÷ 8 = - 3

[tex]x^{2}[/tex] - [tex]x^{2}[/tex] = 1 → - 3

Step 3: Put the polynomial together

2[tex]x^{2}[/tex] + 5[tex]x[/tex] - 3

Answer:

Therefore, Aroha is 17 yrs old and her brother is 14 yrs old.

Step-by-step explanation:

Let's represent Aroha's brother's Agee with the letter "b" yrs old.

If Aroha is 3yrs older than her brother, she's : (b+3) yrs old.

The sum of their ages is 31,

b+(b+3)=31

2b+3=31

Collect like terms,

2b=31-3

2b=28

Divide both sides by 2,

b=14

b+3=17

Answer:

X = 5

Step-by-step explanation:

Answer: x = 5

Step-by-step explanation:

Solve for x given the equation 2(x - 2)² = (2x - 1)(x - 3).

Simplify the equation.

2(x - 2)(x - 2) = (2x - 1)(x - 3)

2(x² - 4x + 4) = (2x² - 7x + 3)

2x² - 8x + 8 = 2x² - 7x + 3

Solve for x.

2x² - 8x + 8 = 2x² - 7x + 3

              -8                  - 8

2x² - 8x = 2x² - 7x - 5

       +8x         + 8x

2x² = 2x² + x - 5

 -x              - x

2x² - x = 2x² - 5

-2x²      - 2x²

- x = - 5

- 5 ÷ - 1 = 5

x is equal to 5.
