Answer:
5 units
Step-by-step explanation:
The distance from a point (m, n ) to the line Ax + By + C = 0 is given by
d = 
For the point (- 1, 3 ) , with m = - 1 and n = 3
3x - 4y = 10 ( subtract 10 from both sides )
3x - 4y - 10 = 0
with A = 3 , B = - 4 , C = - 10
d = 
= 
= 
= 
= 5

(5 * sqrt(x^7))^3
Recall sqrt(x^2)=x
So we get (5*x^6 )^3
5*3 is 25, 6*3 is 18 (and exponent to an exponent multiplies)
Therefore the answer is 25x^18
Answer:
The cafeteria provides three meals per day.
<u>Reason 1</u>
Yes, they vary directly
As number of days increases ,Total number of meals i.e
1st day ⇒ 3
2nd day⇒6
3 rd day⇒9
4th day⇒12
......................
.........................
increases.
Total number of Meals = k×Number of days
But there is another possibility also
<u>Reason 2</u>
1 st day ⇒ 3
2nd day ⇒3
3rd day⇒ 3
.....................
.....................
As you can see from the above expression On each day number of meals is
constant.
So we can say that ,
On each Day=Constant amount of meal=3
So, there is no Proportionality between Days and Meal.
Answer:
100% growth rate or it doubles
Step-by-step explanation:
This is of the form
y = ab^x
where a is the initial value and
b is the growth/decay factor
b>1 growth
b<1 decay
Since b>1 it is growth
We determine the growth rate by
b-1
2-1 =1
Multiply by 100%
1*100% = 100 % growth rate
