What is the length of CD? In this diagram, ABC - EDC.
A. 2
B. 3
C. 4
D. 5


Answer:

length of radius of a circle = 3

Step-by-step explanation:

a tangent line touches the circle at one point

if the tangent line is at x=13 (vertical line) and the center of the circle is

(x,y) = (10,-14) with its center x at 10; then take the difference to find the radius;

x(tangent line) - x(center of circle) = radius of circle

length of radius of a circle = 13-10 = 3

you can also graph the circle and draw the tangent line to find the radius

The length of the radius of a circle as described in the question is; 14.32

The center of the circle is at; (10, -14)

The line that is tangent to the circle is; x = 13.

The coordinate of a point on the line is therefore; (13, 0)

The length of the radius of the circle can.be obtained from Pythagoras theorem as;

Answer:

X= 17.5

Step-by-step explanation:

the outside of the triangle always = 180

so you need to add up all the sides and equal to 180

5x+35+x+5+2x=180

add like terms

8x+40=180

get the x alone

x=17.5

Answer and Step-by-step explanation:

A)    A(t) = 5000(1 + 0.012)t

B)    A(t) = 106260

A) 5000 is the initial amount, 1 + 0.012 is the interest rate, and t represents the years.

B) When we plug 21 into the equation,  we get 106260.

Answer:

x  = 5t - a

Step-by-step explanation:

The problem deals with making a variable the subject of the formula in the expression.

 Given expression:

            6x + a = 5(x + t)

  We are to make x the subject of the formula in the expression

Solution:

           6x + a  = 5(x+t)

On the right hand side, expand the parentheses and distribute the term outside;

          6x + a  = 5x + 5t

   Bring the term desired to be the subject to one side by adding (-5x) to both sides;

     6x + (-5x) + a = 5x + (-5x) + 5t

           x + a  = 5t

  Now add (-a) to both sides

         x + a + (-a) = 5t + (-a)

          x  = 5t - a

Answer: there's no answer, the correct answer is f(x) = -14x3 + 7x2

Step-by-step explanation:

1. f(x) = 14x3 − 7x2 + 6

2. reflection over y-axis : f(x) = -14x3 + 7x2 - 6

3. shift 6 units up : f(x) = -14x3 + 7x2 - 6 + 6

4. f(x) = -14x3 + 7x2

The correct function after reflection across the y-axis and shifts it 6 units up is,

⇒ h (x) = - 14x³ - 7x² + 12

A relation between a set of inputs having one output each is called a function.

We have to given that;

The function is,

⇒ f (x) = 14x³ - 7x² + 6

Now, After reflection across the y-axis we get;

⇒ f (x) = f (- x)

⇒ f (-x) = 14 (-x)³ - 7 (-x)² + 6

⇒ f (-x) = - 14x³ - 7x² + 6

And, After shifts it 6 units up, we get;

⇒ f (x) = f (x) + 6

Hence, We get the value of function is,

⇒ h (x) = - 14x³ - 7x² + 6 + 6

⇒ h (x) = - 14x³ - 7x² + 12

"what are angles"

Step-by-step explanation:

En la geometría euclidiana, un ángulo es la figura formada por dos rayos, llamados lados del ángulo, que comparten un punto final común, llamado vértice del ángulo. Los ángulos formados por dos rayos se encuentran en el plano que contiene los rayos. Los ángulos también se forman por la intersección de dos planos. Estos se llaman ángulos diedros

Answer:

12.77 miles per hour

Step-by-step explanation:

Step 1

Convert the diameter from inches to feet

Your bike has a wheel diameter of 29 inches.

1 inch = 0.0833 feet

29 inches =

29 × 0.0833 feet

= 2.41667 feet

Step 2

Circumference of the tire = πD

= π × 2.41667 feet

= 7.5921927182 feet

Step 3

The number feet traveled per hour is

148 revolutions per minute × 7.5921927182 feet

= 1123.6445223 feet per minute

60 minutes = 1 hour

Hence,

1123.6445223 × 60 =

67418.671337 feet per hour.

Converting from Feet per hour to Miles per hours

1 mile = 5280 feet

= 67418.671337 feet per hour/5280 feet

= 12.768687753 miles per hour

Approximately = 12.769 miles per hour

Answer:

9.091(1.1^n)

Step-by-step explanation:

Given the height of a tree for the past 4 years given by the sequence;

10ft, 11ft, 12.1ft, 13.31ft...

We can see that the sequence is in geometric progression since they have a common ratio;

The nth term of a geometric progression is expressed as;

Tn = ar^n-1

a is the first term

r is the common ratio

Given

a = 10

r = 11/10 = 21.1/11 = 13.31/12.1 = 1.1

Substitute into the formula;

Tn = 10(1.1)^{n-1}

Tn = 10(1.1^n)/1.1

Tn = 9.091(1.1^n)

Hence the recursive formula for the height of the tree is expressed as  9.091(1.1^n) where n is the total number of tree.
