Deductive reasoning is what is proven and what you already know for sure. Example: there are 2 ants. There is 1 ant next to the 2. There are 3 ants total. (Rules of addition)

So you don't have to solve any problems to use deductive reasoning, unlike inductive reasoning, which is not proven
Example of inductive reasoning: there are lots of girls in my class. So there are probably lots of girls in the other classes too. You don't know that for sure.

Writes formula for f(n), the nth term of the arithmetic sequence 1,4,7,10,13

F(n)= x+3. This shows that each number in the sequence was a result of adding three to the previous number. So if you plug a number into the formula shown, you will get the following number.

Please help asap!<br><br>the problem is in the picture

Given:

$AB=6\ BC=r,\ CD=r,\ AD=12$ .

To find:

The value of r.

Solution:

We have,

$AB=6\ BC=r,\ CD=r,\ AD=12$ .

We know that the radius is perpendicular to the tangent at the point of tangency

AD is the tangent and CD is the radius. So, CD is perpendicular to AD at point D, i.e., $m\angle D=90^\circ$ .

Using Pythagoras theorem, we get

$AC^2=AD^2+CD^2$

$(6+r)^2=12^2+r^2$

$36+12r+r^2=144+r^2$

$12r=144+r^2-36-r^2$

On further simplification, we get

$12r=108$

$r=\dfrac{108}{12}$

$r=9$

Therefore, the value of r is 9.

A portion of a map with cities a and b is shown.The map uses a scale of 1 inch to 30 miles. A new map has a scale of 2 inches=15

Alina [70]

Answer:

22.5miles

Step-by-step explanation:

For Map 1;

1 inches = 30miles

For Map 2:

2 inches = 15miles

1 inches = x

2x = 1 *15

x = 15/2

x = 7.5miles

This means that 1 inch represents 7.5miles on Map 2'

The distance between the two cities in miles = 30miles - 7.5miles

The distance between the two cities (in miles) = 22.5miles
