Answer:
Use Distance Formula
Step-by-step explanation:
You can find the distance between two points by using the distance formula which by definition is 
For example take question 3. Plug your point values in to find the distance
Point 1 is (-1, 8)
Point 2 is (-3, -2)
You equation would look like:
This simplifies to 
=
=
=
=
That is the distance between the points (-1, 8) and (-3, -2)
Answer:
24a^9b^4
Step-by-step explanation:
you would multiply 4a^2 and 24^a^7b^3.
Answer: What I do not know is the measurement of the third side.
Step-by-step explanation: The first thing to explain over the phone is that this is a scalene triangle. Two sides have been identified, and two angles have also been identified. For an equilateral triangle, all three sides and all three angles must be equal. For an isosceles triangle, two sides and two angles must be equal. In this diagram, two angles have been given as 88° and 50°. The third angle be derived as
88 + 50 + X = 180
138 + X = 180
X = 42.
If all three angles are now given as 88, 50 and 42 then the triangle is definitely a scalene triangle, and this would surely mean the measurement of the third side would be different from the other two. And to calculate the third side would require the application of the Sine Rule, which would in itself require the use of a calculator and careful mathematical calculations.
200 meters were swam in (2*60+42=162) seconds.
(200/50=4) laps were swam.
The time per lap was 162/4=40.5 seconds.
