Answer:
1) See figure attached
2)
a) 
And if we replace we got:
b) 
And if we replace we got:
Step-by-step explanation:
Part 1
We can see the plot in the figure attached.
Part 2
a)
For this case we have two points 
And we want to find the distance travelled between these two points and we can use the following formula from the euclidian distance between two points:
And if we replace we got:
b)
Since it takes two seconds in order to go from (6.9) to (10,15) we can use the definition of velocity:
And if we replace we got:
Answer:
∠ EAB = 85°
Step-by-step explanation:
∠ EBC and ∠ BCD are same- side interior angles and sum to 180° , so
∠ BCD = 180° - ∠ EBC = 180° - 148° = 32°
the sum of the 3 angles in Δ ADC = 180° , that is
∠ EDC + ∠ BCD + ∠ EAB = 180°
63° + 32° + ∠ EAB = 180°
95° + ∠ EAB = 180° ( subtract 95° from both sides )
∠ EAB = 85°

In order to get the common denominator when adding fractions or subtracting fractions, you have to make sure that the denominator of the two items are divisible by each other. In this case, 9 is not divisible by any of the given denominators which is 4 and 5. So in this case, the common denominator will have to be 20. 5 x 4 will equal to 20 and you will also multiply 3 x 5 to get the new numerator. After that, you will multiply 2 x 4 to get the new numerator of the other fraction. The new fractions will be 15/20 and 8/20. From there, you can add or subtract
Answer:
Floor ride up to = 13 floor
Step-by-step explanation:
Given:
Parking garage = 4 floors under ground
Elevator up-to = 17 floor
Find:
Floor ride up to
Computation:
Floor ride up to = Elevator up-to - Parking garage
Floor ride up to = 17 floor - 4 floor
Floor ride up to = 13 floor
