Step-by-step explanation:

[tex]f^{-1} (x)=3+\frac{x}{2}[/tex]

Answer:

f(x)^-1 = 1/2x +3

Step-by-step explanation:

f(x) = 2x-6

y =2x-6

Exchange x and y and solve for y

x = 2y -6

Add 6 to each side

x+6 = 2y

Divide by 2

(x+6)/2 = 2y/2

(x+6)/2 =y

1/2x +3 =y

This is the inverse of f(x)

f(x)^-1 = 1/2x +3

Answer:

The solution is:

Part A. [tex]\sqrt{5}^{\frac{7k}{3}})[/tex] which is sqrt(5)^7k/3[/tex]

Part B. k = 18/7

Step-by-step explanation:

Part A.

To solve this part, we're going two use THREE important properties of exponents:

1. [tex](x^{n})^{m} = x^{nm}[/tex]

2. [tex]\frac{x^{n}}{x^{m}} = x^{n-m}[/tex]

3. [tex]\sqrt[n]{x^{m}} = x^{\frac{m}{n} }[/tex]

Let's work the numerator using the properties 1, 2 and 3:

[tex](\sqrt{5}^{3} )^{\frac{k}{9} } }  = (\sqrt{5}^{3\frac{k}{9}}) = (\sqrt{5}^{\frac{k}{3}})[/tex]

Let's work the denominator using the properties 1, 2 and 3:

[tex](\sqrt{5}^{6} )^{-\frac{k}{3} } }  = (\sqrt{5}^{6\frac{k}{3}}) = (\sqrt{5}^(2k))[/tex]

Now dividing the numerator by the denominator:

[tex]\sqrt{5}^{\frac{k}{3}-(-2k)})=\sqrt{5}^{\frac{7k}{3}})[/tex]

Part B

if [tex]5^{\frac{3}{2} } 5^{\frac{3}{2}} = \sqrt{5}^{\frac{7k}{3}})[/tex]

Then:

[tex]5^{3} = 5^{\frac{7k}{6}})[/tex]

So [tex]\frac{7k}{6}} = 3[/tex]

Solving for k, we have:

k = 18/7

[tex]\bf \cfrac{3}{30}\implies \cfrac{3\cdot 1}{3\cdot 10}\implies \cfrac{3}{3}\cdot \cfrac{1}{10}\implies 1\cdot \cfrac{1}{10}\implies \cfrac{1}{10}[/tex]

Answer:

The answer is x=2

Step-by-step explanation:

Answer:

B x = 2

Step-by-step explanation:

As you can see you have to find out what equals 4 AND what equals 12 and to make sure:

Do 2x2 is 4 because 4 times 1 yes but 6 times 1 is not 12 its 26 therefore C is INCORRECT

A Is Also wrong because 6 x 1 is 6 sure yes 4 x 1 is for but they both have to be equal so A is INCORRECT

And Is wrong because 8 x 4 is 32 but we are looking for what equals 4 not 32 and 6 x 8 is 48 we are looking for a 12 so D is INCORRECT

Now what leaves is B well 2 x 2 =4 and 2 x 6 = 12 Therefore B is Correct! Another way you can do this is to divide 12 ÷ 6 = 2 and 4 ÷ 2 = 2

Hope this helps!

Answer:

A) 7

B) 1

C)6

D) 7

Step-by-step explanation:

Clock arithmetic is just like the basic arithmetic you know... with one difference... there are no numbers beyond 12 (or 24).

In your question, you seem to indicate to consider only the 12-hour clock system, much like it is used in the USA.

So, every time you pass 12, you start at 1 again. So, your answer has to be under 13.  If your answer is still > 12 after you subtracted 12, subtract 12 again, and again, and again, until you get something <= 12.

That's what we call a modulo 12.

A) 8 + 11 = 19...  but then you subtract 12... 19 - 12 = 7

B) 4 + 9 = 13, 13 - 12 = 1

C) 7 * 6 = 42, 42 - 12 = 30, 30-12 = 18, 18 -12 = 6

D) 5 * 11 = 55, 55 - 12 = 43, 43 - 12 = 31, 31 - 12 = 19, 19 - 12 = 7

By performing the calculations and finding the remainders, we can determine the answers to the given expressions. The required answers are: A) 7, B) 1, C) 6, D) 7.

Let's solve each calculation step by step:

A) 8 + 11 (12 clock): 8 + 11 is 19. Since we are using a 12-hour clock, we need to take the remainder when dividing 19 by 12. 19 divided by 12 gives a remainder of 7. So, the answer is 7.

B) 4 + 9 (12 clock): 4 + 9 is 13. Dividing 13 by 12 gives a remainder of 1. So, the answer is 1.

C) 7 x 6 (12 clock): 7 multiplied by 6 is 42. Dividing 42 by 12 gives a remainder of 6. So, the answer is 6.

D) 5 x 11 (12 clock): 5 multiplied by 11 is 55. Dividing 55 by 12 gives a remainder of 7. So, the answer is 7.

Answer:

$1594.40

Step-by-step explanation:

The question is on monthly benefit for social security

Average amount earned per month=$3750

Benefit earned in first $680 = 90/100 ×3750 = $612

Benefit earned for amount over $680 = 32/100 ×($3750-$680)

0.32×3070=$982.40

Total amount earned as benefit per month= $612+$982.40 =$1594.40

Final answer:

Mr. Jenkins' monthly Social Security benefit is calculated by adding 90% of the first $680 of his average monthly earnings to 32% of the earnings above $680. The total benefit comes out to be $1,594.40 per month.

Explanation:

To calculate Mr. Jenkins' monthly Social Security benefits, we use the formula provided which incorporates two rates: 90% of the first $680 earned, and then 32% of the earnings over $680. Since Mr. Jenkins has an average monthly income of $3,750, the calculation would look like this:

First $680 of earnings: $680 x 0.90 = $612

Remaining earnings: ($3,750 - $680) x 0.32 = $3,070 x 0.32 = $982.40

Total monthly benefit: $612 + $982.40 = $1,594.40

Therefore, Mr. Jenkins' monthly Social Security benefit will be $1,594.40.

EXPLANATION

The given triangle is a right isosceles triangle because one angle is 90° and the base angles will be 45° each.

This means that:

[tex]a = b[/tex]

Using, the Pythagorean Theorem, we have

[tex] {a}^{2} + {a}^{2} = {(9 \sqrt{2} )}^{2} [/tex]

We simplify to get:

[tex]2{a}^{2} = 81 \times 2[/tex]

[tex]{a}^{2} = 81[/tex]

Take positive square root,

[tex]a = \sqrt{81} [/tex]

This implies that

[tex]a = 9[/tex]

Therefore b is also equal to 9

The correct answer is A.

Answer: option a

Step-by-step explanation:

You can use these identities:

[tex]sin\alpha=\frac{opposite}{hypotenuse}\\\\cos\alpha=\frac{adjacent}{hypotenuse}[/tex]

Then, to find "a" you know that:

[tex]\alpha=45\°\\adjacent=a\\hypotenuse=9\sqrt{2}[/tex]

Substituting:

[tex]cos(45\°)=\frac{a}{9\sqrt{2}}[/tex]

Now you must solve for "a":

[tex]a=cos(45\°)(9\sqrt{2})\\\\a=9in[/tex]

To find  "b", you know that:

[tex]\alpha=45\°\\opposite=b\\hypotenuse=9\sqrt{2}[/tex]

Substituting:

[tex]sin(45\°)=\frac{b}{9\sqrt{2}}[/tex]

Now you must solve for "b":

[tex]b=sin(45\°)(9\sqrt{2})\\\\b=9in[/tex]

Answer: 14/25 = 56/100

               11/20 =  55/100

               14/25 > 11/20

Step-by-step explanation:

The least common multiple of 20 and 25 is 100.

(100 = 20*5, 25*4)

So we can take the common denominator 100.

14*4/25*4 =56/100. ∴14/25 = 56/100

11*5/20*5  =55/100. ∴11/20  = 55/100

56>55

∴56/100 > 55/100

∴14/25 > 11/20

Hope it's good;)

Answer:

125 times larger

Step-by-step explanation:

Let's say the radius is 3, just as an example.

The formula of a sphere is V=4/3 pi r^3

Then we can just substitute and test it out.

V=4/3 pi (3)^3

V=4/3 pi (27)

V=36 pi

Then multiple the previous radius by 5 to test it out.

V=4/3 pi (15)^3

V=4/3 pi (3375)

V=4500 pi

Then divide the bigger one by the smaller one

You will get 125, therefore it is 125 times larger

Answer:

51.3

Step-by-step explanation:

This is a right triangle (because of the 90° angle).  For any right triangle, you can use the following:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

You can remember this as SOH-CAH-TOA.

We want to find the angle y.  We know that the opposite side is 10 and the adjacent side is 8.  So we can use tangent:

tan y = 10 / 8

y ≈ 51.3°

Answer:

Rounded to the nearest hundredth: 2.34 g/cm³

Step-by-step explanation:

Here's the formula to find the Density: [tex]p=\frac{m}{v}[/tex]

This is what the variables mean:

p = density

m = mass

V = volume

Now let's see what clues you have from this toy spoon!

p = ? We are going to solve to find out!

m = 7.5 grams

V = 3.2 mL

First, we should know that there is only 1 gram in each mL and vise-versa, so there is no need to convert these measurements.

Next, we plug in the values from what we know into the equation.

This is the formula: [tex]p=\frac{m}{v}[/tex]

Now if we plug in our values we get: [tex]p=\frac{7.5}{3.2}[/tex]

From that we get, p = 2.34375‬

Finally, if we round our answers we get:

Rounded to the nearest hundredth: 2.34 g/cm³

Rounded to the nearest tenth: 2.3 g/cm³

g/cm³ is the unit for density (in grams), so its up to you to put it or not!

Have an amazing day!! (♡°▽°♡) I hope you found this helpful ;))

The density of the toy spoon is approximately 2.34 g/mL.

The density of an object is calculated by dividing its mass by its volume. In this case, the mass of the toy spoon is 7.5 grams and its volume is 3.2 mL. To find the density, we divide the mass by the volume:

Density = Mass / Volume = 7.5 g / 3.2 mL

Calculating this, we get a density of approximately 2.34 g/mL.

Answer:

The probability of rolling a 3 or a 6 is 1/4....

Step-by-step explanation:

Number of times outcome occurred = 10+6+4+8+6+6

Number of times outcome occurred = 40

Number of times 3 occurred = 4

Number of times 6 occurred = 6

Now add both the values: 4+6 =10

Now to find the  experimental probability of rolling a 3 or a 6, You just simply divide number of times outcome occurred by 10

= 10/40

Cancel the term by the table of 5.

10/40

=2/8

Now further divide it by the table of 2

= 1/4

Thus the probability of rolling a 3 or a 6 is 1/4....
