If the basic measuring unit in base-7 is 49 circles, what does the measuring unit of size .001seven look like
Serjik [45]

The measuring unit is the standard unit of a quantity

The measuring unit of size 0.001 is represented by one millionth circle

<h3>How to determine the unit of base 0.001</h3>

The basic measuring unit in base 7 is given as:

49 circles

The above can be represented as:

Base 7 = 49 circles

Represent the base with n.

So, we have the following rule

Circle = n^2

For measuring unit 0.001, we have:

Circle = 0.001^2

Evaluate the square

Circle = 0.000001

This means that,

The measuring unit of size 0.001 is represented by one millionth circle

What is the instataneous rate of change at x=2 of the function f given by f(x)= x^2-2÷x-1​
Dima020 [189]

Answer:

4.5

Step-by-step explanation:

To find the instantaneous rate of chance, take the derivative:

f(x) =  {x}^{2}  -  \frac{2}{x}  - 1 \\  \frac{d}{dx} f(x) = 2x +  \frac{2}{ {x}^{2} }

Remember to use power rule:

\frac{d}{dx}  {x}^{a}  = a {x}^{a - 1}

To differentiate -2/x, think of it as:

- 2 {x}^{ - 1}

Then, substitute 2 for x:

2(2) +  \frac{2}{ {2}^{2} }  \\ 4 +  \frac{2}{4}  = 4.5

The sum of three numbers is 88. The first number is 8 more than the second. The third number is 3 times the second. What are the
Sever21 [200]

Answer:

The numbers are 24, 16 and 48

Step-by-step explanation:

For this equation you need to use all the information you have to add in 3 variables, use the information you have to connect them, so you only use one number. You’ll have the second number (x), the first number (x+8) and the third number (3x) now we use all of that to make an equation.

88=x+(x+8)+3x

Now you simplify the equation,

88=5x+8

Now get the x and it’s coefficient alone on one side

80=5x

Now divide both sides so the x is alone

x=16

Since the second number was x you know the second number

the first number is x+8 since x is 16 the first number is 24

The third number is 3 * x so the third number is 48.

So the numbers are 24, 16 and 48
