Answer:
1. 7
2. 48
Step-by-step explanation:
you have to <u>subtract</u> 49-42 because some got taken away then you should end up with 7, 63-15 is 48.
Answer:
Part A) The triangles ABC and EDC are similar by AAA, because the three internal angles are equal in both triangles
Part B) The width of the river is about ![39\ ft](https://tex.z-dn.net/?f=39%5C%20ft)
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
Part A) we know that
In this problem , triangles ABC and CDE are similar by AAA, because its corresponding angles are congruent
so
m<DCE=m<ACB -----> by vertical angles
m<EDC=m<ABC -----> is a right angle
m<DEC=m<CAB -----> the sum of the internal angles must be equal to 180 degrees
Part B) we know that
The triangles ABC and EDC are similar -------> see Part A
therefore
![\frac{BC}{DC}=\frac{AB}{DE}](https://tex.z-dn.net/?f=%5Cfrac%7BBC%7D%7BDC%7D%3D%5Cfrac%7BAB%7D%7BDE%7D)
substitute the values and solve for AB
![\frac{65}{25}=\frac{AB}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B65%7D%7B25%7D%3D%5Cfrac%7BAB%7D%7B15%7D)
![AB=15*(\frac{65}{25})=39\ ft](https://tex.z-dn.net/?f=AB%3D15%2A%28%5Cfrac%7B65%7D%7B25%7D%29%3D39%5C%20ft)

Givens
a = 4.4 m/s^2 This is an acceleration and is positive.
vi = 10.2 m/s
t = 4.2 seconds
vf = ????? The cruising speed in this case is vf.
Formula
a = (vf - vi)/t Notice the 3 givens and what you seek determine the formula
Solve
4.4 m/s^2 = (vf - 10.2)/4.2 Multiply both sides by 4.2
4.4 * 4.2 = vf - 10.2
18.48 = vf - 10.2 Add 10.2 to both sides
18.48 + 10.2 = vf 8.28 is the second best answer.
28.68 = vf This is your cruising speed.
