Answer:

The length RS = 7

Step-by-step explanation:

Here, we are interested in determining the length of RS

Let’s have the line segment arranged as follows;

Q R S

where QR = 9 and QS = 16

From the arrangement, we can deduce that;

QS = QR + RS

Thus;

RS = QS - QR

RS = 16 -9

RS = 7

Answer:

x = 4

Step-by-step explanation:

Cancel common factor of 9,

(x/5)=(4/5)

Multiply both sides by 5,

(5x/5)=(20/5)

Simplify to get x = 4

5 - ( x - 2 )

substitute -

5 - ( -1 -2 )

first solve the bracket

5 - ( - 1 - 2 )

therefore,

5 - ( - 3 )

solve

= 8

Answer:

1/16 or 0.0625

Step-by-step explanation:

we can take 4 outside the parentheses and we would get 4^(4-7+1)=4^(-2)= 1/(4^2)=1/16=0.0625.

Answer:

0.0625

Step-by-step explanation:

[tex]4^{4}[/tex] ( [tex]4^{-7}[/tex] ) (4)

First lets deal with 4^4 which is 256 (4 * 4 * 4 * 4)

256 ( [tex]4^{-7}[/tex] ) (4 )

Then 4^-7 which is [tex]\frac{1}{16384}[/tex] ( this is because when 4^-7 is simplified it becomes 1/4^7 which is 1/16384.

256 ( [tex]\frac{1}{16384}[/tex]) (4)

256 * [tex]\frac{1}{16384}[/tex] * 4= 0.0625

Answer:

[tex]x=\frac{30}{(1+x)}[/tex]

Step-by-step explanation:

step one:

This is a word problem, we need to translate is it to mathematical terms before we solve

"When x is added to its square, the total is 30"

step two:

[tex]x+x^2=30[/tex]

[tex]x+x^2=30\\\\x(1+x)=30\\\\[/tex]

step three:

divide both sides by 1+x we have the value of x as

[tex]x=\frac{30}{(1+x)}[/tex]

Answer:

(fg)(x) = x^3-4x^2-16x+64, D: All Real Numbers

Step-by-step explanation:

(fg)(x) = f(x) x g(x)

= 16-x^2(4-x)

=64-16x-4x+x^3

(fg)(x) = x^3-4x^2-16x+64

Domain is all real numbers because you can substitute any real number for x and the function would still work.

Thus the value of [tex](fg)(x) = x^3 -4x^2 -16x -64[/tex] , and the domain is a set of real numbers.

The domain is a set of all real numbers because by substituting any value in the equation we only get real numbers.

The function is defined as a relationship between two variables a dependent and an independent variable. A function consists of a domain and a co-domain.  The set of codomains is called a range.

      Example : [tex]f(x) = 4x+ 3[/tex]

All those values of a set for which a function is defined are called a domain.

According to the question :

[tex]f(x) = 16 - x^2\\ g(x) = 4 - x.[/tex]

[tex](fg)(x) = (16- x^2) (4-x)\\(fg)(x) = [16(4-x) -x^2(4- x)]\\\(fg)(x) = [64- 16x -4x^2+x^3]\\(fg)(x) = x^3 -4x^2 -16 x -64[/tex]

Thus the value of [tex](fg)(x) = x^3 -4x^2-16x-64.[/tex]

Use the Circumference of a Circle Formula:

C = 2πr

or

C = (Diameter)*π    (since diameter = 2*radius)

In this case, the diameter is 44 miles

So the circumference is:

C = 44*π = 138.23 miles

Answer:

Answer: k = $0.50

Step-by-step explanation:

The data that we have is:

Rocko paid: $12.50 for 25 tickets.

Louisa paid: $17.50 for 35 tickets.

Now, the question asks to find the constant of proportionality.

A proportional relation can be written as:

y = k*x

where k is the constant, and in this case, y is the price and x the number of tickets bought.

Then replacing with the values above, we have:

$12.50 = k*25

then:

k = $12.50/25 = $0.50

And the other data:

$17.50 = k*35

K = $17.50/35 = $0.50

So we have the same k in both cases, this means that the constant of proportionality is k = $0.50

Answer:

Converse- If q, then p. Contrapositive- If not p, then not q

Step-by-step explanation:

Let's say your conditional is if an angle is 90 degrees then it is a right angle.

Then the converse is, if an angle is a right angle then it is 90 degrees.

Finally, the contrapositive is if an angle is not 90 degrees then it is not a right angle.

Answer:

1- it is irrational

2- it is rational
