Answer:

The length from the external point to the center of the circle is 5 cm

Step-by-step explanation:

Here, we want to calculate the distance from the center of the circle to the external point

Please check attachment for diagram

Now, from what we know, the tangent and the radius meets at right angle

So we have a right-angled triangle with the length from the external point to the center of the circle as hypotenuse;

While the radius and the length of the tangent to the circle as the other sides

Using Pythagoras’ theorem, the square of the hypotenuse equals the sum of the squares of the two other sides

Let the length we want to calculate be x

x^2 = 3^2 + 4^2

x^2 = 9 + 16

x^2 = 25

x = √25

x = 5 cm

Answer:

x = 4

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

7(2x - 5) = 21

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 21 does indeed equal 21.

∴ x = 4 is the solution to the equation.

8.00-1.25=6.75 so I believe this the answer

Based on the given parameters, Eli’s speed is 5/60 miles per minute

The speed of an object is the rate of change of the distance moved by the object with respect to time

The given parameters are

Distance = 5/6 miles

Time = 10 minutes

The speed is calculated as

Speed = Distance/Time

So, we have

Speed = 5/6 miles/10 minutes

Evaluate

Speed = 5/60 miles per minute

Hence, Eli’s speed is 5/60 miles per minute

Answer:

2/3

Hope this helps.

Answer:

2^3 * 3

Step-by-step explanation:

Here are the first several prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23

To find the prime factorization of a number, start by dividing the number by the smallest prime number it is divisible by. Keep dividing by that prime number until you can't anymore. You only divide by prime numbers that divide evenly. Then move on to the next prime number that divides evenly, and do the same. You eventually will get to 1. Then you put together all the prime factors.

This is much easier to do than it sounds like in this explanation.

Start with 24.

24/2 = 12

12/2 = 6

6/2 = 3    3 is not divisible by 2, so we move on to 3.

3/3 = 1    We got to 1, so we are done.

The prime factorization is the product of all the prime numbers we divided by which are in bold.

24 = 2 * 2 * 2 * 3

Now we index it:

24 = 2^3 * 3

Answer:

x = 3 is the solution

Step-by-step explanation:

3x + 4 = 5x - 2

when x = 3

so plug 3 into the equation where x is

so the equation becomes:

3(3) + 4 = 5(3) - 2

Then do the multiplication on both sides

9 + 4 = 15 - 2

Then do the addition and subtracition on both sides

13 = 13

Answer:

3x +4= 5x-2

3(3) +4 = 5(3) -2 (plug in the x values)

9+4= 15-2 (do the multiplication on both sides)  

13= 13 (do the addition/ subtraction. pretty much all you're doing, is making sure that with the given x-value, the equation is true. and it is :))

Answer: -25

Step-by-step explanation:

The required integer that shows that 25 feet below the sea level is -25.

Given that,
To determine the in integer that represents 25 feet below sea level.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
The sea level is set to equal to 0,
Now height above the seal level comprises of positive sign, and the height below the sea level comprises of negative sign.
So, for  25 feet below sea level,
-25 is the required integer that represents the  25 feet below sea level.

Thus, the required integer that shows that 25 feet below sea level is -25.

Answer:

Growth rate is -1/5

Growth factor is 4/5

Step-by-step explanation:

Here, we want to get the growth rate and the growth factor

Generally for an exponential function given as;

y = a(1 + r)^n

r is the growth rate

1 + r is the growth factor

We can express the given exponential function as follows;

f(x) = 200(1-1/5)^x

So the growth rate is -1/5

The growth factor is 1-1/5 = 4/5
