Answer:
√58 or 7.61 units
Step-by-step explanation:
Given points are:
A(1,4)
B(-2,-3)
The distance formula is used to find distance between two points.
The distance formula is:

So the approximate distance is √58 or 7.61 units ..
Answer:
It will cost: £28.28
Step-by-step explanation:
Area of sphere = 4 x π x r2
Area of Circle = 4 x π x 3^2 = 113.097 (radius is half of diameter)
113.097 / 0.25 = 28.28
Try this option:
According to property such triangle
1. area=0.5*a*b, where a and b - the sides of angle 90°.
Using this equation: 180=0.5*40*b, ⇒ b=9.
2. c²=a²+b², ⇒c=√(9²+40²)=41 - the third side of the triangle;
3. Perimeter=a+b+c=9+40+41=90 cm.
answer: 90 cm.
Answer:

Step-by-step explanation:
apply the inverse properties of logarithmic and exponential functions to simplify

Inverse property of log says that

we apply this property in our problem. ln has same base 'e' . so ln and e gets cancelled




Answer:
Is important to remember that the reflection of the point (a,b) across the y-axis is the point (-a,b).
Our original equation is 
And after the reflection respect x we got:
