Is a 100 degree angle a right angle?.

The differences between their ages is equal to 15 years.

Since the ages of two brothers are in the ratio 8:3, the age of the first (1st) brother would be represented by 8x while the age of second (2nd) brother would be represented by 3x.

Note: The variable x represents the age in years.

After 3 years, the age of the first (1st) brother would be represented by 8x + 3. Similarly, the age of second (2nd) brother would be represented by 3x + 3.

Translating the word problem into an algebraic equation by using ratios, we have the following:

(8x + 3)/(3x + 3) = 9/4

4(8x + 3) = 9(3x + 3)

32x + 12 = 27x + 27

32x - 27x = 27 - 12

5x = 15

x = 15/5

x = 3.

Now, we can determine the age of the brothers;

First brother's age = 8x = 8 × 3 = 24 years.

And, 2nd brother's age = 3x = 3 × 3 = 9 years.

For the difference, we have:

Difference = 24 - 9

Difference = 15 years.

An equation is an expression showing the relationship between numbers and variables.

One little cat can eat a bag of treats in 15 minutes while another cat can eat the same bag of treats in 10 minutes.

a) In 2 minutes:

Part of bag eaten = (1/15 minutes) * 2 minutes + (1/10 minutes) * 2 minutes = 1/3

1/3 of the bag would be eaten by both cats in 2 minutes.

b) In 5 minutes:

The cube of 5 is 125

We know that the cube of a number is the value that are obtained when a number is multiplied by itself three times.

We can find cubes for any real number.

If p be any real valued number then the cube of p is the product of number p  three times.

i.e., p × p × p

The cube of number is represented by the third power (exponent) of that number.

for above the cube of number 'p' is represented by p³

Here we need to find the cube of number 5.

From definition of cube of number,

5³ = 5 × 5 × 5

5³ = 25 × 5

5³ = 125

Thus the cube of number 5 = 125

The process to sketch the graph of y =  absolute value x is explained below .

What is Absolute Value ?

The absolute value of a number is the distance of the number from origin of a number line. It is denoted as |a|, which defines the magnitude of any integer "a". Absolute Value is represented by two vertical lines "|a|" , which is called as modulus of a .

we have to sketch the graph of the absolute function given as ; y = |x| ;

put x = -2 , we get ⇒ y = 2 ;

put x = 2 , we get ⇒ y = 2 ;

we see that if we put any value of "x" , positive or negative , the result "y" will always be positive .

The account will be worth $215,958.88 after 3 years. This can be calculated by using the formula: A = P(1 + r/n)^(nt) where A is the final amount, P is the initial principal (or balance) of $165,000, r is the annual interest rate of 8%, n is the number of times that interest is compounded per year (annually in this case, so n = 1), and t is the number of years the money is invested for (3 in this case).

Plugging these values into the formula: A = 165,000(1 + .08/1)^(1*3) = 215,958.88.

The inverse of a function "swaps" the x and y values of the original function. To find the inverse of f(x) = 9x², we need to switch the x and y values and solve for x in terms of y:

y = 9x²

To find the inverse function we must isolate x.

x = √(y/9)

So the inverse of the function f(x) = 9x², x ≤ 0 is f^-1(x) = √(x/9), x ≤ 0.

Answer:

[tex]f^{-1}(x)=\dfrac{\sqrt{x}}{3}, \quad x \leq0[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=9x^2[/tex]

The domain of the given function is restricted:  {x : x ≤ 0}

The range of the given function is restricted:  {f(x) : f(x) ≤ 0}

To find the inverse of a function, swap x and y:

[tex]\implies x=9y^2[/tex]

Rearrange the equation to make y the subject:

[tex]\implies x=3^2y^2[/tex]

[tex]\implies x=(3y)^2[/tex]

[tex]\implies \pm\sqrt{x}=3y[/tex]

[tex]\implies y=\dfrac{\pm\sqrt{x}}{3}[/tex]

As x ≤ 0 then:

[tex]\implies y=\dfrac{\sqrt{x}}{3}[/tex]

Replace y with f⁻¹(x):

[tex]\implies f^{-1}(x)=\dfrac{\sqrt{x}}{3}[/tex]

The domain of the inverse of a function is the same as the range of the original function.  Therefore, the domain of the inverse function is restricted to {x : x ≤ 0}.

If UV = x and TW = x+99 ,using triangle proportional theorem, then the value of x is 99

Triangle proportion theorem states that if a line is drawn parallel to any one side of a triangle so that it intersects the other two sides in two distinct points, then the other two sides of the triangle are divided in the same ratio.

since TU = TS and S W = VW. This show that triangle SUV is an isosceles triangle

then TW / UV = 1/2

therefore x/-x+99 = 1/2

Truth serum has 91% accuracy when guilty, 94% accuracy when innocent, 6% false positive, 9% false negative.

What is percentange ?

Percentage is a way of expressing a number as a fraction of 100. It is often denoted by the symbol "%" (percent sign) and it's used to express a proportion or ratio. For example, if a student scored 80 out of 100 in an exam, the percentage score would be 80%, which means the student answered 80 out of 100 questions correctly.

A truth serum given to a subject is known to have a 91% reliability rate when the person is guilty and a 94% reliability rate when the person is innocent. This means that when the person is guilty, there is a 91% chance that the truth serum will indicate that the person is guilty, and a 9% chance of a false negative (indicating the person is innocent when they are guilty). Similarly, when the person is innocent, there is a 94% chance that the truth serum will indicate that the person is innocent, and a 6% chance of a false positive (indicating the person is guilty when they are innocent).

Since there are two complex conjugates as the roots of the quadratic equation 5x2 4x 3 0 there is no way to describe them in terms of real integers.

The roots can only be roughly calculated because they are irrational numbers.

Two complex conjugates, which are unable to be expressed in terms of real numbers, make up the roots of the quadratic equation 5x2 4x 3 0. Using the quadratic formula, the roots can be discovered. The coefficients of the equation are necessary for the formula, and in this example, they are a=5, b=4, and c=3. When the quadratic formula is used, two complex roots are produced, denoted by the expressions x1 = -1/5 + (16)/5i and x2 = -1/5 - (16)/5i.

Answer:120

Step-by-step explanation:

given x= 3 and y= 8,

we have to find the value of 5xy

so let us put the values of x and y in the given expression i.e 5xy.2

= 5×3×8

= 120

 Hence the value of 5 xy is 120.

Answer:

Step-by-step explanation:

If x = 3 and y = 8, then the value of 5xy is simply 5 times the product of x and y.

To find the product of x and y, we simply multiply x and y together:

xy = 3 * 8 = 24

To find the value of 5xy, we simply multiply 5 by the value of xy:

5xy = 5 * 24 = 120

So the value of 5xy when x = 3 and y = 8 is 120
