Given:

Initial value of the stock = $100

Growth factor = 1.5 each week.

To find:

The equation that represents the relationship between the number of weeks past since purchase and the current value of the stock.

Solution:

Let V be the current value of the stock after t week.

The exponential growth model is:

[tex]V=ab^t[/tex]

Where, a is the initial value of stock, b is the weekly growth factor, t is the number of weeks.

Substituting [tex]a=100,b=1.5[/tex], we get

[tex]V=100(1.5)^t[/tex]

Therefore, the required equation for the given situation is [tex]V=100(1.5)^t[/tex].

Answer:

  (-7, -11)

Step-by-step explanation:

  [tex]\dfrac{x^2+3x-28}{x+7}=\dfrac{(x+7)(x-4)}{x+7}=x-4\qquad x\ne-7[/tex]

The hole is at x=-7. The left- and right-limits at that point are -7-4 = -11. So, the coordinates of the hole are (-7, -11).

Answer:

A. True

B. False

C. True

D. False

E. True

The mixed fraction equations which are true are C , D and E

A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

Given data ,

Let the mixed number equation be represented as A

Now , the value of A is

To solve each equation, we can convert mixed numbers to improper fractions, then multiply the fractions, and simplify the result if possible.

A)

A = 5/6 × 4 2/3 = (5/6) × (4×3 + 2)/3

A = (5/6) × 14/3 = 35/9, which is not equal to 3 8/9.

Therefore, equation A is false.

B)

B = 1 1/10 × 8 3/5 = (11/10) × (43/5)

B = 473/50 = 9 23/50, which is not equal to 9 1/2.

Therefore, equation B is false.

C)

C = 3 2/9 × 2 1/6 = (29/9) × (13/6)

C = 377/54 = 6 53/54

Therefore, equation C is true.

D)

D = 2 3/7 × 1 7/8 = (17/7) × (15/8)

D = 255/56 = 4 23/56 = 2 3/8

Therefore, equation D is true.

E)

E = 7/12 × 4 = 7/3 = 2 1/3

Therefore, equation E is true.

Hence , the equations that are true are C, D, and E

The size of the angle m∠PRQ for the polygon is equal to 15°

To calculate the sum of interior angles of a polygon, you can use the following formula:

Sum of interior angles = (n-2) x 180 degrees

Where "n" represents the number of sides (or vertices) of the polygon.

Given the 12 sided polygon;

(12 - 2) × 180 = 1800

one interior angle = 1800/12 = 150°

The angle PQR is a base angle of the Isosceles triangle ∆PQR with one interior angle of the 12-sided polygon so;

m∠PRQ = (180 - 150)/2

m∠PRQ = 15°.

Therefore, the size of the angle m∠PRQ for the polygon is equal to 15°

Answer:

The volume of the triangular pyramid to the nearest whole number is 924 inches cube

Answer:

69.3 meters squared

Step-by-step explanation:

1) Think of the shape as being divided into two sections (a rectangle and a triangle)

2) multiply 5.2 times 7 to find the area of the rectangle (36.4)

3) subtract 5.2 from 14.6 to find the base of the triangle (9.4)

4) multiply 9.4 by the height of the triangle 7 (65.8)

5) divide 65.8 by two because a triangle is half of the needed rectangle

6) this leaves 32.9

7) add 32.9 and 36.4 to get your final answer of 69.3 meters squared

Answer:

Ray DC and Ray DE

Answer:

Step-by-step explanation:

By zero product property,

Zeros of the given quadratic equation,

m² - 121 = 0

m² - (11)² = 0

(m + 11)(m - 11) = 0

m = -11. 11

Option C is the answer.

9x² - 3x - 2 = 0

9x² - 6x + 3x - 2 = 0

3x(3x - 2) + 1(3x - 2) = 0

(3x + 1)(3x - 2) = 0

x = [tex]-\frac{1}{3}, \frac{2}{3}[/tex]

Option B is the answer.

4x² + 2x - 6 = 0

2x² + x - 3 = 0

2x² + 3x - 2x - 3 = 0

x(2x + 3) - 1(2x + 3) = 0

(x - 1)(2x + 3) = 0

x = [tex]-\frac{3}{2},1[/tex]

Option A is the answer.

In accordance with the research problem we were given, Pete outran Jacob by 37 seconds.

Minutes are the 60 equal pieces that make up each degree. Thus, 7 to 8 inches can also be written as seven degrees and thirty minutes, or seven°30'. For example, 2 ° 5 minutes and 30 seconds are represented by the notation 2° 5' 30 since each minutes is further subdivided into 60 equal seconds.

Then, we have Pete's time: First, we convert minutes into seconds. 13 minutes and 39 seconds is equal to 13 * 60 + 39, or 819 seconds.

Jacob's period: 14 minutes and 16 sec. = 14 * 60 + 16 sec. = 856 sec.

Jacob outpaced Pete by 856 – 819 = 37 seconds.

Pete ran 37 seconds faster as a result.

Dado que :

Número inicial de bananas = 272

Número de bananas devolvidas com = 129

Para obter o número de bananas vendidas, usamos a operação de subtração do número de bananas com que ela saiu de casa e do número de bananas com que voltou.

Portanto, número de bananas vendidas:

372 - 129 = 243

Given:

The area of the squares are given.

To find:

The exact side length or estimate side length of the square.

Solution:

We know that, the area of a square is

[tex]A=a^2[/tex]

Where, a is the side length of the square.

[tex]a=\sqrt{A}[/tex]

Area of the square is 100 square units. So, the side length is:

[tex]a=\sqrt{100}[/tex]

[tex]a=10[/tex]

Therefore, the side length is 10 units.

Area of the square is 95 square units. So, the side length is:

[tex]a=\sqrt{95}[/tex]

It is not exact. We know that [tex]\sqrt{81}<\sqrt{95}<\sqrt{100}[/tex].

Therefore, the side length is between 9 and 10.

Area of the square is 36 square units. So, the side length is:

[tex]a=\sqrt{36}[/tex]

[tex]a=6[/tex]

Therefore, the side length is 6 units.

Area of the square is 30 square units. So, the side length is:

[tex]a=\sqrt{30}[/tex]

It is not exact. We know that [tex]\sqrt{25}<\sqrt{30}<\sqrt{36}[/tex].

Therefore, the side length is between 5 and 6.

Have a good day

Assuming that Anita needs hollow right circular cones, we are solving for its lateral surface area, which is given by the formula πr√ (h²+r²), where r is the radius and h is the height.

r = 6 ft / 2 = 3 ft

Solving for the lateral surface area of one cone:

LSA = (3.14) (3) [√ (12²+3²) ] = 116.52 sq ft.

Since she needs 10 cones:

10 * 116.52 sq. ft = 1,165.2 sq ft.

She will need 1,165.2 sq ft of material.

Hope this helps you :)
