Answer:
distance = sqrt( 65 ) ~= 8.06
Step-by-step explanation:
To find the distance between two points, we can use the distance formula.
distance = sqrt( [x2 - x1]^2 + [y2 - y1]^2)
distance = sqrt( [-5 - 2]^2 + [3 - -1]^2)
distance = sqrt( [-7]^2 + [4]^2)
distance = sqrt( 49 + 16 )
distance = sqrt( 65 ) ~= 8.06
Cheers.
Answer:
627.65 times
2.51^(10 - m) times
Yes, it makes sense
Step-by-step explanation:
Given that,
A magnitude 9 star is 2.51 times as bright as a magnitude 10 star
To find
<h3>a) </h3>
How many times as bright is a magnitude 3 star as a magnitude 10 star
10 - 3 = 7
2.51^7
627.65 times
<h3>b)</h3>
Expression to compare a magnitude m star to a magnitude 10 star
2.51^(10 - m) times
<h3>c)</h3>
Yes, it makes sense as a full moon is magnitude -13
so,
2.51^(10 - (-13))
2.51^(23)
1557742231 times
Answer:
Length, l = 10 m, breadth = 8 m
Step-by-step explanation:
Let l be the length and b be the width of the rectangle.
The area of a rectangle is given by :
A = lb
80 = lb ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
36 = 2(l+b)
18 = (l+b) ....(2)
We need to solve equation (1) and (2). On solving we get :
l = 10, b = 8
So, the dimensions of the shop is 10 m and 8 m.
Answer:what
Step-by-step explanation:
The percentage of error in deters measurement is 8.50%
6 - 5.49 = 0.51%
100% = .51/6
100% = 8.5%
