f(x)=2x
which expression represents f^-1(x)?

Answers

Answer 1

Answer:

hey !

your answer is C

x=

x/2

Step-by-step explanation:

Answer 2

If the function f(x)=2x then the inverse function is  f⁻¹(x) =x/2.

What is a function?

A relation is a function if it has only One y-value for each x-value.

The given function is f(x)=2x.

y=2x

Interchange the variables.

x=2y

Now solve for y

y=x/2

Replace y with f⁻¹(x) to show the final answer.

f⁻¹(x) =x/2

Hence, if the function f(x)=2x then the inverse function is  f⁻¹(x) =x/2.

A new car sells for $27,500. The value of the car decreases by 14% annually. You want to sell the car when it's worth about $4000. Explain how many years you will keep the car, when you will sell it, and how you determined your answer.

Answers

Answer:

The formula would be:

27500 x (1 - 14/100)^year = 4000

=> (86/100)^year = 4000/27500

=> 0.86^year = 0.145

=> year = log(0.145)/log(0.86) = 12.8

Hope this helps!

:)

Answer:

13 years

Step-by-step explanation:

4000 = 27500 × (1 - 14/100)^t

4000 = 27500 × 0.86^t

0.86^t = 8/55

t ln(0.86) = ln(8/55)

t = 12.78248711

A cylinder has a radius of 14 m and a height of 6 m. What is the exact volume of the cylinder? 84π m³ 168π m³ 504π m³ 1176π m³

Answers

Answer:

1176π m³

Step-by-step explanation:

The formula for the volume of a cylinder is:

V = πr²h

Let's substitute the values given into this equation:

V = πr²h

V = (π)(14²)(6)

Solve:

V = (π)(14²)(6)

V = (π)(196)(6)

V = 1,176π

Therefore, the volume of the cylinder is 1176π cubic meters.

Answer:

1176

Step-by-step explanation:

r (radius) = 14 m

h (height) = 6 m

v (volume) = ?

Formula: V=πr2h

We are looking for the volume of the cylinder. We know that the Radius is 14 and the height is 6.

So we need to

1: Radius * 14 * 6

2: Radius * 196* 6

Answer: 1176

In triangle ABC, a=√2, b=1, and measure of angle a=90. Find the measure of angle B.

Answers

Answer:

In the triangle ABC,  A is the right angle;  the side "a", opposite to the angle A, is the hypotenuse and side "b" is the leg.

√ (√2)²-1² = √2-1= √1= 1

according to the Pythagorean theorem.

It means that you have the right angled triangle with congruent legs; thus the triangle is isosceles.

Hence, the angles at the base (at the hypotenuse) are congruent and each is equal to  180°-90°/2 = 45°

Answer.  The measure of the angle B is 45°.

Step-by-step explanation:

The required value of the angle B is obtained as 45°.

What are trigonometric ratios?

The trigonometric ratios are defined for a right angled triangle.

The example of these ratios are sin, cos, tan, cosec, sec and cot.

The trigonometric ratios are useful in determining the heights and distances of the large objects.

The given problem can be shown in the form of diagram as below,

The measure of given sides and angle of the triangle are as below,

∠A = 90°, a = BC = √2 and b = AC = 1.

Use the trigonometric ratio to obtain,

Sin∠B = BC/AC

⇒ Sin∠B = 1/√2

⇒ ∠B = 45°

Hence, the measure of angle B is given as 45°.

Today Aimee is 1/3 of Jamie's age. In 12 years, Aimee will be 50% of Jamie's age. How old will Aimee be next year? Please answer quickly, there are bonus points

Answers

Answer:

Next year Aimee will be 13 years old

Step-by-step explanation:

Let's call Aimee's age A, and Jamie's age J.

From the information given, we have that:

A = (1/3) * J

A + 12 = (1/2) * (J + 12)

Using the value of A from the first equation in the second one, we have:

J/3 + 12 = J/2 + 6

J/2 - J/3 = 6

J/6 = 6

J = 36

Now we can find A:

A = (1/3) * 36 = 12

So next year Aimee will be 13 years old

Answer:

Aimee will be 13 years old next year/

Step-by-step explanation:

A stands for Aimee, and J stands for Jamie.

A = (1/3) * J

A + 12 = (1/2) * (J + 12)

Using the value of A from the first equation in the second one, we have:

J/3 + 12 = J/2 + 6

J/2 - J/3 = 6

J/6 = 6

J = 36

Now we can find A:

A = (1/3) * 36 = 12

In conclusion, Aimee will be 13 years old next year.

The simplified form of an expression is StartFraction 1 Over 256 EndFraction t Superscript 28. Which expression was simplified?


A.(256 t Superscript negative 7 Baseline) Superscript 4

B.(4 t Superscript 28 Baseline) Superscript negative 4

C.(256 t Superscript negative 7 Baseline) Superscript negative 4

D.(4 t Superscript negative 7 Baseline) Superscript negative 4

Answers

Answer:

1/258 *(t^28)

= t^28 / 4^4

= t^28 4^-4

= (t^-7 * 4)^-4

= (4t^-7)^-4

The simplified form of an expression   [tex]\frac{1}{256} * t^{28}[/tex] will be [tex](4 t^{-7})^{-4}[/tex] which is given in option number [tex](D)[/tex] i.e. ([tex]4\ t[/tex] Superscript negative [tex]7[/tex] Baseline) Superscript negative [tex]4[/tex] .

What is  simplified form ?

Simplified form a rational expression is considered simplified if the numerator and denominator have no factors in common.

We have,

 [tex]\frac{1}{256} * t^{28}[/tex]

Now to simplify it,

Convert [tex]256[/tex] into a exponent form with a base.

i.e.

[tex]\frac{1}{4^4} * t^{28}[/tex]

Now,

Using the exponent rule;

[tex]\frac{1}{a^n}= a^{(-n)}[/tex]

So,

[tex]4^{-4}\ *\ t^{28}[/tex]

Now, simplify it more by taking common power of [tex]4[/tex] and [tex]t[/tex] ,

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

⇒ [tex](4 t^{-7})^{-4}[/tex]

So, this is the simplified form of given expression which is given in option number [tex](D).[/tex]

Hence, we can say that the simplified form of an expression   [tex]\frac{1}{256} * t^{28}[/tex] will be [tex](4 t^{-7})^{-4}[/tex] which is given in option number [tex](D)[/tex] i.e. ([tex]4\ t[/tex] Superscript negative [tex]7[/tex] Baseline) Superscript negative [tex]4[/tex] .
