Answers

Answer 1

Answer:

b) [tex]f^-1(x)[/tex]= ∛(4x-24)

c)2

Step-by-step explanation:

these ones are inverse functions

change the f(x) for y and make x the subject

y= x³/4 +6

(y-6)x 4 = x³

∛(4y-24)= x

then put x back were y is

[tex]f^-1(x)[/tex]= ∛(4x-24)

and to do c just put in 8 where x is

∛(4(8)-24)= 2

Consider all positive integers that are multiples of 10 and are less than or equal to 200. What fraction of those integers are multiples of 15?

A. 1/20

B. 3/20

C. 3/10

D. 2/5

E. 3/4

Answers

i think the answer would be E

The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Consider all positive integers that are multiples of 10 and are less than or equal to 200.

Let the number of the positive integer that are multiples of 10 be x. Then the equation will be

10x ≤ 200

Then the value of the x will be

x ≤ 20

The set of numbers is given below.

Set = 20 {10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200}

The set which is divisible by 15 will be

Set = 6 {30, 6,0 90, 120, 150, 180}

Then the fraction of those integers are multiples of 15 will be

⇒ 6 / 20

⇒ 3/10

The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

Answers

Step-by-step explanation:

step 1. (13x + 8) + (2x + 7) = 180 (definition of same side interior angles)

step 2. 15x + 15 = 180 (like terms)

step 4. x = 11. (divide both sides by 15)

Write 2 41/50 as a percent

Answers

Answer:

282%

Step-by-step explanation:

2 and 41/50 is also 82/100 so 282%

The mixed number A = 2 41/50 as a percentage is P = 282 %

Given data ,

Let the percentage value be represented as P

Now , the mixed number is given as A

where the value of A = 2 41/50

On simplifying the number , we get

A = 2 82/100

where the conversion of a fraction to a percent, we divide the numerator by the denominator and multiply by 100.

(141/50) x 100 = 282/1

On simplifying the equation , we get

P = 282%

Therefore, 2 41/50 is equal to 282%

Hence , the percentage value is A = 282 %

Doctors sometimes use this formula to calculate how much medicine to give a child. A child who is 4 years old needs some medicine. The amount for an adult is 20 ml. Use the formula to work out the correct amount for this child.

Answers

Answer:

A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity

Step-by-step explanation:

Medications are available in multiple concentrations, therefore orders written in "mL" rather than "mg" are not acceptable and require further clarification.

...

Example 2.

Step 1. Calculate the dose in mg: 18 kg × 100 mg/kg/day = 1800 mg/day

Step 2. Divide the dose by the frequency: 1800 mg/day ÷ 1 (daily) = 1800 mg/dose

Here is a square inscribed in a circle with radius 1 meter. What is the perimeter of
the square? Explain or show your reasoning

Answers

Answer:

[tex]4\sqrt{2}[/tex]

Step-by-step explanation:

distance formula:[tex]\sqrt{\left(x_2-x_1\right)^{2}+\left(y_2-y_1\right)^{2}}[/tex]

set square to be centered on the origin and find the distance between 2 of the connected points

[tex]\sqrt{\left(3-2\right)^{2}+\left(2-1\right)^{2}}[/tex]

= [tex]\sqrt{\left(1\right)^{2}+\left(1\right)^{2}}[/tex]

= [tex]\sqrt{2}[/tex]

multiply by 4 as it is a square and all of its sides are equal

[tex]4\sqrt{2}[/tex]

insert units

[tex]4\sqrt{2}\ \ meters[/tex]

The perimeter of the square is √32.

Given to us

the radius of the circle is 1 meter

What is the diagonal of the square inscribed in the circle?

As we can see in the figure AB is the diagonal of the square and diameter of the circle. therefore,

AB = Diagonal of the square = Diameter of circle = 2 x Radius = 2 meter

We know the diagonal of a square is equal to the product of √2 and the side of the square.

[tex]Diagonal = side \times {\sqrt2}[/tex]

Substitute the value,

[tex]2 = side \times {\sqrt2}\\\\side = \dfrac{2}{\sqrt2}\\\\side ={\sqrt2}[/tex]

What is the perimeter of the square?

The perimeter of the square is four times the side of the square.

[tex]Perimeter = 4\times (side)[/tex]

Substitute the value,

[tex]Perimeter = 4\times (\sqrt2)\\\\Perimeter = 4\sqrt2 = \sqrt{2\times 16} = \sqrt{32}[/tex]

Hence, the perimeter of the square is √32.

A computer costs $800. It loses ¼ of its value every 2 years after it is purchased.

How much will the computer be worth in 6 years?

Answers

The computer will be worth $200.

Step-by-step explanation:

A quarter of $800 is $200, so the computer loses $200 dollars in value every two years. Since 6÷2 is 3, you multiple $200 by 3 to get $600. You then subtract $600 from $800 and get $200.

Answer: The value of the computer at time 0 is $800

The value of the computer at time 1 is $600

The value of the computer at time 2 is $450

All I know is that you have to subtract 1575 from 5,000 and then you get 3,435 dollars left and you divide that by 26 people and you get 131.731 but of course you can't have a half of person so it stays at 131.

Which is a solution to the equation?
(x - 3)(x - 5) = 35
Ox= -8
O x= -5
O x= 2
O x = 10

Answers

Answer:

x=10

Step-by-step explanation:

Let's solve your equation step-by-step.

(x−3)(x−5)=35

Step 1: Simplify both sides of the equation.

x2−8x+15=35

Step 2: Subtract 35 from both sides.

x2−8x+15−35=35−35

x2−8x−20=0

Step 3: Factor left side of equation.

(x+2)(x−10)=0

Step 4: Set factors equal to 0.

x+2=0 or x−10=0

x=−2 or x=10
