Answer:

180,000 (OR 90,000 if the figure is a triangle)

Step-by-step explanation:

3 x 3 x 5 x 5 x 4 x 8 x 5 x 5 = 180,000

Area = 180,000

IF THE FIGURE IS A TRIANGLE THEN DIVIDE 180,000 BY 2 AND YOU WILL GET 90,000 AS THE AREA

A ) ⅔ x + 6 = 16

→ ⅔ × 15 + 6 = 16

10r -24 = 7r + 12

→ 10r - 7r = 12+24

→ 3r = 36

→ r = 12

→ 3r - 2r + 8r = 10+8

→ r + 8r = 18

→ 9r = 18

→ r = 2

m/3-18 = m + 6

→ 54- m/ 3 = m + 6

→ 54- m = m + 6×3

Answer:

The answer to this question is D

Step-by-step explanation:

i solved it

The correct answers are A) 7cm, C) 9cm and D) 12cm

The process of changing a given quantity that is expressed in one unit of measurement to another unit of measurement that is equivalent in value is referred to as conversion of units.

If every 2 cm on a scale drawing is equal to 7 feet in real life, then we can use proportions to find out which lines on the drawing would be greater than 21 feet in real life.

Let x be the length of a line on the scale drawing in centimeters. Then, we can set up the following proportion:

⇒  [tex]\frac{2cm}{7 feet} = \frac{x cm }{yfeet}[/tex]

where y is the length of the line in real life. Solving for y, we get:

⇒  [tex]y = \frac{7 feet} {2cm} *x[/tex]  

⇒  [tex]y = 3.5 x feet[/tex]

If we put x = 2cm (given) then, y = 7 feet

For y = 21 feet, the value of x = 6cm.

Therefore, any line on the scale drawing that is greater than 6cm in length corresponds to a length greater than 21 feet in real life.

So, the lines on the drawing that are greater than 21 feet in real life are:

A) 7cm, C) 9cm, D) 12cm

Therefore, the correct answers are A) 7cm, C) 9cm and D) 12cm

Answer:

t = 6.8 years

Step-by-step explanation:

The formula for compound interest is

[tex]A(t)=P(1+r/n)^n^t[/tex], where P is the principal/amount invested, r is the interest rate, n is the number of compound periods per year (4 for quarterly), and t in the time in years.

We know that A = $5900, P = $4000, and r = 0.0575 (we must convert the percentage to a decimal).  We must solve for t and round to the nearest tenth:

[tex]5900=4000(1+0.0575/4)^(^4^t^)\\\\59/40=(1623/1600)^4^t\\\\log(59/40)=log(1623/1600^4^t)\\\\log(59/40)=4t*log(1623/1600)\\\\log(59/40)/log(1623/1600)=4t\\\\1/4(log(59/40)/log(1623/1600))=t\\\\6.80773607=t\\\\6.8=t[/tex]

The cross product of (a - b) and (a + b) is: [-8, -8, -2].

Given the vectors a = (3, 4, -7) and b = (4, 5, 8), you want to compute the cross product of (a - b) and (a + b).

First, let's compute the vectors (a - b) and (a + b):

a - b = (3 - 4, 4 - 5, -7 - 8) = (-1, -1, -15)

a + b = (3 + 4, 4 + 5, -7 + 8) = (7, 9, 1)

Now, let's compute the cross product of the two vectors:

(-1, -1, -15) × (7, 9, 1) = [(-1)(9) - (-1)(1), (-15)(1) - (-1)(7), (-1)(7) - (-1)(9)] = [-8, -8, -2]

So, the cross product of (a - b) and (a + b) is: [-8, -8, -2].

What is circumference of a circle?

Circumference or perimeter of a circle refers to the measuring of its limits. Contrarily, a circle's radius influences the amount of space it takes up. If a circle is opened up and represented by a straight line, its circumference is equal to its length. It is usually measured in units like centimetres or metres. While utilising the formula, the radius of the circle is taken into account when calculating the circle's circumference. Therefore, we need to know the radius or diameter value to determine the circle's perimeter.

Central angle (in radians) = arc length / radius

In this case, we are not given the radius of the circle directly, but we know that the circumference of the circle is 6. We can use the formula for circumference to find the radius:

Circumference = 2 * pi * radius

6 = 2 * pi * radius

radius = 3 / pi

Now we can use the formula for the central angle:

Central angle (in radians) = arc length / radius

Central angle = 1 / (3/pi) = pi/3

Therefore, the central angle of the arc is π/3 radians.

The required rate of return for the stock with a beta of 0.5 is 7.5% and for the stock with a beta of 2 is 15%.

Rate of return is the amount of profit or loss earned on an investment over a certain period of time, expressed as a percentage of the initial investment or total asset value.

A stock is a type of security that represents ownership in a company. Investors buy stocks to become shareholders and share in the company's profits and losses.

According to the given information:

The Capital Asset Pricing Model (CAPM) is expressed as:

R = Rf + beta*(Rm - Rf)

Where:

R = Required rate of return

Rf = Risk-free rate of return

beta = Beta coefficient (systematic risk)

Rm = Expected market return

Using the given values, we can compute the required rate of return for each stock:

Stock with beta of 0.5:

R = 5% + 0.5*(10% - 5%)

R = 7.5%

Stock with beta of 2:

R = 5% + 2*(10% - 5%)

R = 15%

Therefore, the required rate of return for the stock with beta of 0.5 is 7.5%, and the required rate of return for the stock with beta of 2 is 15%.

Answer:

To find the maximum height of the ball, we need to determine the vertex of the parabolic function f(t) = -16t^2 + 5t + 11. The vertex of a parabola is the point where the function reaches its maximum or minimum value.

The x-coordinate of the vertex is given by the formula x = -b/2a, where a and b are the coefficients of the quadratic function. In this case, a = -16 and b = 5, so the x-coordinate of the vertex is:

t = -b/2a = -5/(2*(-16)) = 0.15625

To find the y-coordinate of the vertex, we can substitute t = 0.15625 into the function f(t):

f(0.15625) = -16(0.15625)^2 + 5(0.15625) + 11 ≈ 11.36

Therefore, the maximum height of the ball is approximately 11.4 (rounded to 1/10th).

The area of the triangle with the given vertices is 11.5 square units.

The area of a triangle can be calculated using the coordinates of its vertices using the following formula.

To find the area of a triangle with vertices (x₁, y₁), (x₂, y₂), and (x₃, y₃), we can use the following formula:

A = (x₁(y₂ − y₃) + x₂(y₃ − y₁) + x₃(y₁ − y₂))/2

Using this formula with the given vertices (0, 6), (2, −3), and (3, 4), we get:

A = (0(-3 − 4) + 2(4 − 6) + 3(6 − (-3)))/2

A = (0 - 4 + 27)/2

A = 23/2

A = 11.5

b) x = 27.8

c) 79.4°

Step-by-step explanation:

a) (2x+9) + (3x-4) + 36 = 180

This is because all 3 angles of a triangle equal to 180 degrees.

b) Firstly add like terms

5x + 41 = 180

Subtract 41 from both sides.

An exponential function can be used to calculate the number of trees in the warehouse at the end of any given number of months. This function uses the initial number of trees in the warehouse and the rate of 7.3% to determine the result.

A function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing. As you already know, C programming is built around functions. All C programs have at least one function, which is main(). A function is a group of statements that together perform a task. Every C program has at least one function, main(), and all the other functions are called user-defined functions.

The function that can be used to find the number of trees in the warehouse at the end of m months is an exponential function given by:

N(m) = 45,000(1.073)^m

Where N(m) is the number of trees in the warehouse at the end of m months and 45,000 is the initial number of trees in the warehouse. The rate of 7.3% is represented by 1.073, which is the base of the exponential function.

For example, if we want to find the number of trees in the warehouse at the end of 5 months, we can substitute m = 5 into the exponential function and calculate the result. This gives us N(5) = 45,000(1.073)^5 = 60,731. Thus, the warehouse will contain 60,731 trees at the end of 5 months.

In conclusion, an exponential function can be used to calculate the number of trees in the warehouse at the end of any given number of months. This function uses the initial number of trees in the warehouse and the rate of 7.3% to determine the result.
