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 = 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 :))

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.

Coordinates of the circumscribed circle: U[4; 0.071]

Coordinates of the inscribed circle: I[2.5; 1.473]

Exterior (or external, outer) angles of the triangle:

∠ A' = α' = 150.005° = 150°19″ = 0.524 rad

∠ B' = β' = 118.972° = 118°58'18″ = 1.065 rad

∠ C' = γ' = 91.023° = 91°1'23″ = 1.553 rad

Answer:

When two numbers in an equation have the same variable and or charge, then you use the commutative property to put them next to each other.

Step-by-step explanation:

Example:

4x + 2 + 3x - 1 <--- Here is the original equation.

4x + 3x + 2 - 1 <---Use the commutative property to add the like terms        

                             together. 3x and 4x end in the same variable. 2 and 1 both

                             have no variable. Therefore both of the groups are like    

                             terms.

7x + 1   <--- Add/subtract the live terms together.

8x <--- Here is your answer.

Answer:

The sketch tool to indicate what Edwin is describing as the parabola's "turning point'' is described below in details.

Step-by-step explanation:

We can see in graph that it intersect X axis and it is open upward it means turning point is below X axis, we can find turning point by find maximum value of Y If open downward and minimum value, if open upward here we can find that minimum point is (3, -5). also you can draw axis of symmetry parabola and finds its intersection with turning point can also be named vertex of parabola.

Answer:

a. 4x³+13x²+9

Step-by-step explanation:

1. Distribute 4x to every term in the second set of parenthesis to get:

4x³-16x²+12x

2. Distribute 3 to every term in the second set of parenthesis to get:

3x²-12x+9

3. Add/subtract terms with the same variables/degrees:

4x³-16x²+12x+3x²-12x+9

4. The simplified answer is:

4x³+13x²+9

Answer:

4x³ - 13x² + 9

Step-by-step explanation:

(4x + 3)(x² - 4x + 3) =

(4x)(x²) + (4x)( - 4x) + (4x)(3) + 3(x²) + 3( - 4x) + 3(3) =

4x³ - 16x² + 12x + 3x² - 12x + 9 =

= 4x³ - 13x² + 9

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: -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.
