Adam age is 5 times as old as Charles.
In 8 years’ time, the sum of their ages will be equal to twice Adam’s present age. Find their present age.

Answers

Let Charles age be x

Adam age will be 5x  

8 years later , add 8 to both expressions

Charles age = x+8

Adam age = 5x+8

add their ages and equate them to twice adam's present age 2*5x

x+8+5x+8 = 2*5x

6x+16=10x

4x=16

x=4

x = Charles' age

Adam's age  5x = 5(4) = 20

Applying the angle bisector and triangle proportionality theorem, the solutions are:

16. x = 1/2 or x = 4

17. x = 5

18. x = −1 or x = 6.

What is the Angle Bisector Theorem?

The angle bisector theorem states that when a line segment divides one of the angles of a triangle into two halves, it also divides the triangle to form segments that are proportional to each other.

16. 3x/(x - 1) = (x + 4)/(x - 2) [triangle proportionality theorem]

Cross multiply

(x - 1)(x + 4) = 3x(x - 2)

x² + 3x - 4 = 3x² - 6x

x² - 3x² + 3x - 4 + 6x = 0

-2x² + 9x - 4 = 0

Factorize -2x² + 9x - 4

(−2x + 1)(x − 4)

-2x = -1

x = 1/2

or

x = 4

17. (2x + 2)/(x + 3) = (4x - 2)/(2x + 2)

(2x + 2)(2x + 2) = (4x - 2)(x + 3)

4x² + 8x + 4 = 4x² + 10x - 6

Combine like terms

4x² - 4x² + 8x - 10x = -4 - 6

-2x = -10

x = -10/-2

x = 5

18. (2x + 3)/(x + 4) = x/(x - 2) [angle bisector theorem]

Cross multiply

(2x + 3)(x - 2) = x(x + 4)

Expand

2x² - x - 6 = x² + 4x

2x² - x - 6 - x² - 4x = 0

x² - 5x - 6 = 0

Factorize x² - 5x - 6 = 0

(x+1)(x−6) = 0

x = −1 or x = 6

For the standard normal distribution, find the value of c such that: P(z>c)=0.415 c= (Round your answer to 3 places after the decimal point, if necessary.)

Answers

To find the value of c such that P(z > c) = 0.415 for the standard normal distribution, we need to determine the z-score associated with the given probability. The value of c represents the critical value that corresponds to the area to the right of the z-score.

Using a standard normal distribution table or a calculator, we can find the z-score that corresponds to a probability of 0.415. The z-score represents the number of standard deviations a particular value is away from the mean. In this case, we are interested in finding the z-score that corresponds to the area to the right (greater than) the desired probability.

Using the table or calculator, we find that the z-score associated with a probability of 0.415 is approximately 0.180. Therefore, the value of c is 0.180 (rounded to 3 decimal places).

The top row of seats behind home plate at Cincinnati’s Great American Ball Park is 90 ft above the level of the playing field. The angle of depression to the base of the left field wall is 14 degrees. How far is the base of the left field wall from a point on level ground directly below the top row?

please answer with explanation and diagram if possible :)

Answers

Using the slope concept, it is found that the base of the left field wall is 361 feet from a point on level ground directly below the top row.

What is a slope?The slope is given by the vertical change divided by the horizontal change.It's also the tangent of the angle of depression.

In this problem:

The vertical change is of 90 ft.The horizontal change is of x.The angle of depression is of 14º.

Hence:

\(\tan{14^{\circ}} = \frac{90}{x}\)

\(0.249328 = \frac{90}{x}\)

\(0.249328x = 90\)

\(x = \frac{90}{0.249328}\)

\(x = 361\)

Hence, the base of the left field wall is 361 feet from a point on level ground directly below the top row.

What is an equation?

A mathematical equation is a formula that uses the equals symbol (=) to connect two expressions and express their equality. A well-formed formula consisting of two expressions linked by an equals sign is considered to be an equation in English, but the word's cognates in other languages may have slightly different definitions. For instance, an équation is defined as having one or more variables in French.

The first step in resolving a variable equation is to identify the values of the variables that lead to the equality being true. The variables that must be changed in order to solve the equation are referred to as the unknowns, and the values of the unknowns that satisfy the equality are referred to as the equation's solutions.

Calculations:

16cos(x +8sin(2x)=0

Divide by 8

2cos(x)+sin(2x)=0

Identity:

sin(2x)=2sin(x)cos(x)

2cos(x)+2sin(x)cos(x)=0

Factor:

2cos(x)(1+sin(x))=0

2cos(x)=0

Line l has a slope of m and contains points in quadrants I, II, and IV, but no points from quadrant III. Which of the following must be true about the value of m?
a) m < 0
b) m > 0
c) m = 0
d) slope m is undefined

Answers

The correct answer is (a) m < 0.Since line l contains points in quadrants I, II, and IV, but not in quadrant III, we can deduce the following.

Quadrant I: In this quadrant, both x and y coordinates are positive. For a line in quadrant I, the slope (m) must be positive. Quadrant II: In this quadrant, x coordinates are negative, and y coordinates are positive. For a line in quadrant II, the slope (m) must be positive. Quadrant IV: In this quadrant, x coordinates are positive, and y coordinates are negative. For a line in quadrant IV, the slope (m) must be negative.

Based on the observations in all the relevant quadrants, we can conclude that the slope (m) must be both positive and negative, indicating that it can take on both positive and negative values. Therefore, the correct answer is (a) m < 0.

Step-by-step explanation:

a solid is formed by adjoining two hemispheres to the ends of a right circular cylinder. the total volume of the solid is 10 cubic centimeters. find the radius r (in cm) and height h (in cm) of the cylinder that produces the minimum surface area.

Answers

The radius r that produces the minimum surface area is 1.06 cm and the height h is 1.41 cm.

 

Let r be the radius of the cylinder and h be the height. You can find the equation for the volume of a solid by adding the volumes of the two hemispheres and the cylinder.

Volume = \((2/3)πr^3 + πr^2h\) = 10 cubic centimeters

Now let's find the values ​​of r and h that minimize the surface area of ​​the solid. This area consists of three parts:

Curved surfaces of two hemispheres and sides of a cylinder. This can be expressed as:

surface area = \(2πr^2 + 2πrh\)

To find the values ​​of r and h that minimize this expression, we can use the Lagrangian multiplier method. Given that the volume of the solid is 10 cubic centimeters, we want to minimize the surface area. So it looks like this:

\(f(r, h) = 2πr^2 + 2πrh + λ[(2/3)πr^3 + πr^2h - 10]\)

Taking the partial derivatives for r, h, and λ and setting them to zero gives

\(4πr + 2πh = 2πr^2λ + (4/3)πr^3λ\)

\(2πr = πr^2λ + πrhλ\)

Solving these equations simultaneously gives:

h = 4r/3

λ = 2/(3r)

Substituting these values ​​into the volume equation gives:

\(r^2h = 5/3\)

Substituting h = 4r/3 from above, we get:

\(r^3 = 15/8pi\)

Taking the cube root of both sides gives:

r=1.06cm

Substituting this value for r into the formula for h yields:

h=1.41cm

Therefore, the radius r that produces the minimum surface area is about 1.06 cm and the height h is about 1.41 cm.

Find the present value of a sequence of annual payments of Rs 25000 each , the first being made at the end of 5th year and the last being paid at the end of 12th year, if money is worth 6%.

Answers

The present value of the sequence of annual payments of Rs 25000 each, the first being made at the end of the 5th year and the last being paid at the end of the 12th year, if money is worth 6% is Rs. 158620.39.

1: We can use the formula to calculate the present value of the annuity:

P = A x [1 - (1+i)^-n] / i

Where

P = Present Value

A = Annuity

i = Interest Raten = Number of payments

2: Calculate the present value of each payment using the formula:

P1 = 25000 / (1.06)⁵

P2 = 25000 / (1.06)⁶

P3 = 25000 / (1.06)⁷

P4 = 25000 / (1.06)⁸

P5 = 25000 / (1.06)⁹

P6 = 25000 / (1.06)¹⁰

P7 = 25000 / (1.06)¹¹

P8 = 25000 / (1.06)¹²

3: Substitute the values into the formula to find the present value:

P = P1 + P2 + P3 + P4 + P5 + P6 + P7 + P8

P = (25000 / (1.06)⁵) + (25000 / (1.06)⁶) + (25000 / (1.06)⁷) + (25000 / (1.06)⁸) + (25000 / (1.06)⁹) + (25000 / (1.06)¹⁰) + (25000 / (1.06)¹¹) + (25000 / (1.06)¹²)

in the diagram,the measure of angle ACB is 25 degrees. what is the measure of angle AOB?

Answers

Answer:

m<AOB = 50°

Step-by-step explanation:

<ACB = 25° is an inscribed angle of the circle.

<AOB is a central angle of the circle.

Thus, based on the inscribed angle theorem which states that an inscribed angle is ½ the measure of the central angle, therefore:

m<ACB = ½(m<AOB)

25° = ½(m<AOB)

Multiply both sides by 2

2*25 = m<AOB
