Hope it will help :)

Answer 2
If x=3 than
x^3 = 3^3
3^3=27

A race car can travel at a speed of 3.4 x 10^2 miles/hour. The Speed of Sound is approximately 7.6 × 10^2 miles/hour. How many times faster is the Speed of Sound than the Bullet Train?

Answers

Answer:

The speed of sound is 2.23 times of the speed of race car

Step-by-step explanation:

Given that,

The speed of a race car = [tex]3.4\times 10^2\ mi/h[/tex]

The speed of sound = [tex]7.6\times 10^2\ mi/h[/tex]

Dividing the speed of sound to the speed of a race car. So,[tex]\dfrac{\text{speed of sound}}{\text{speed of race car}}=\dfrac{7.6\times 10^2}{3.4\times 10^2}\\\\\dfrac{\text{speed of sound}}{\text{speed of race car}}=2.23[/tex]

So, the speed of sound is 2.23 times of the speed of race car.

3x-5/6=1/6 what does x=?

Answers

Answer:

x = 2

Step-by-step explanation:

[tex]\frac{3x-5}{6} = \frac{1}{6} \\[/tex]

In order to solve this, you must get the denominator off of the left-hand side of the equation, by multiplying 6 on each side, in order to get the denominators to cancel. This leaves you with:

[tex]3x-5 = 6/6\\3x-5 = 1[/tex]

Then, you add 5 to each side.

[tex]3x = 6[/tex]

Divide by 3, to get x by itself.

[tex]x = 2[/tex]

Which gets us to our final answer of x = 2.

Then, you can plug x back into the equation just to double-check yourself:

[tex]\frac{3(2)-5}{6} = \frac{1}{6} \\\\\frac{6-5}{6} = \frac{1}{6}\\\\\frac{1}{6} = \frac{1}{6}[/tex]

I hope that this helped you understand to concept a little better. Good luck.

Jerome is a dietician who tracks his daily caloric intake from different sources of nutrients. Here are summary statistics for his daily values: Let T represent the total calories from fat, protein, and carbohydrates that Jerome consumes on a randomly chosen day. Find the standard deviation of T​

Answers

Answer:

It can not be determined from the information given because the calorie sources are not independent.

Step-by-step explanation:

Explained in answer above.

There is no enough information to calculate the standard deviation of T.

Check below on how to determine the standard deviation

What is standard deviation?

The standard deviation of a dataset is how much the data elements of the dataset are far from the mean or average value of the dataset

The given parameters are the mean and the standard deviations of calories from fat, protein, and carbohydrates

These values are not enough to determine the standard deviation of T

Hence, there is no enough information to calculate the required standard deviation

What is the vertex for the quadratic
y = 2(x-3)^2 - 4? Type as (h.k)

Answers

Answer:

(3,-4)

Step-by-step explanation:

You can find the vertex where x = -b/2a

To find the values of a and b, it would be easier to write the equation in standard form, which is y = ax^2 + bx + c

y = 2(x^2 - 6x + 9) - 4

y = 2x^2 - 12x + 18 - 4

y = 2x^2 - 12x + 14

In this equation, a = 2 and b = -12.

So let's plug that into x=-b/2a

x = -(-12)/2(2)

x = 12/4

x = 3

Now we have the x, we can just plug that into the original equation and get the y coordinate for the vertex.

y = 2(x - 3)^2 - 4

y = 2(3 - 3)^2 - 4

y = -4

Autumn invested $69,000 in an account paying an interest rate of 6 3/8% compounded continuously. Jayden invested $69,000 in an account paying an interest rate of 6 1/4% compounded quarterly. After 14 years, how much more money would Autumn have in her account than Jayden, to the nearest dollar?

Answers

Answer:

4,038.21

Step-by-step explanation:

I'm going to assume that when you write 6 3/8% that equals 51/8%=6.375%

To find the value in the first equation we have

69000*e^(.06375*14)=168,444.5313

The second equation is as follows

69000(1+(.0625/4))^(14*4)=164,406.3243
