Answer:
these problems are always tough b/c they want you to translate normal thinking into math jargon :D soooo....
Step-by-step explanation:
they use the point slope formula... which looks like
y = = m(x - )
where ( , ) are the x , y coordinates of some point you're given.. sooo
they give us two points.. so we can put either one of those into the formula.. but we also have to find m.... or the slope ... to find m.. use the slope equation of
m = ( - ) / ( - )
call either point P1 and P2 ... i'll pick the top point as P1 and bottom as P2
then
m = ( -3 -1 ) / ( 1 - 3 )
m = -4 / -2
m = 2 ( yay :) )
now use either point and plug it into the point slope formula, i'll use P1
y - 1 = 2(x-3) ( this is the answer they are looking for )
Answer:
The number he thought of was 13
Step-by-step explanation:
Revers the problem
3.5 * 3 = 10.5
10.5 - 4 = 6.5
6.5 * 2 = 13
Let us draw a triangle ABC with A=15° ,B=113° and b=7.
Please see the attached image.
We know that the sum of interior angles of a triangle is 180 degrees. Thus, we have
Apply Sine rule in the triangle ABC, we get
Therefore, we have
Answer:
7.24 * 10^-5
Step-by-step explanation:
Answer:
{\bold{\sqrt{2} \text { and } \sqrt{8}} are the two irrational numbers, where their product 4 is the rational number
To Find:
Two irrational numbers whose product is the rational number
Solution:
A number is said to be rational number if that number is written as fraction and an irrational number cannot be written as the ratio of any two integers.
For example, square roots.
Now, we can take 2 and 8\sqrt{2} \text { and } \sqrt{8}
2 and 8
as irrational number.
By multiplying them,
2×8=16=4\sqrt{2} \times \sqrt{8}=\sqrt{16}=4
2 ×8=16=4
We know that 4 is the rational number.
