Answer:
4.8 inches
Step-by-step explanation:
<em>See comment for complete question</em>
Represent the larger triangle with 1 and the smaller with 2.
So, we have:
-- height of 1
Required
Determine H2 --- Height of 2
To do this we apply dilation formula.

In this case:

Substitute 6 for H1 and 0.8 for Scale Factor


Hence, the height of the smaller triangle is 4.8 inches

Step-by-step explanation:
Lin runs for 29 seconds at 7.2 meters per second. What is her finish point?
time= 29 seconds
speed= 7.2 m/s
distance= speed*time
distance= 7.2*29
distance=208.8
m
Elena runs for 26 seconds and finishes at 240 meters. What is her velocity?
time= 26 seconds
distance= 240meters
velocity= distance/time
velocity= 240/26
velocity=9.23 m/s
Diego runs for 33 seconds at -6.1 meters per second. What is his finish point?
time= 33 seconds
velocity
distance=velocity*time
distance=33*6.1
distance= 33*6.1
distance=201.3
m
Andre runs for 38 seconds and finishes at -295 meters. What is his velocity?
time= 38 seconds
distance= 295m
velocity= distance/tim
velocity= 295/38
velocity= 7.76m/s
Answer:
y = root under 24 (evaluate it if necessary)
or y = 2 root 6
Step-by-step explanation:
Let the reference angle be x
for the triangle in left,
b = 6-4 = 2
Now,
taking x as refrence angle,
cosx = b/h
or, cosx = 2/h
again,
for the bigger triangle,
taking x as reference angle,
cosx = b/h
or, cosx = b/6
As we can see base of bigger triangle is equal to hypotenuse of triangle at the left,
Let's suppose its a
so, cosx = a/6 = 2/a
now,
a/6 = 2/a
or, a² = 12
now,
for bigger triangle, using pythagoras theorem,
h² = p²+b²
or, 6² = y² + a²
or, 36 = y² + 12
or, y² = 24
so, y = root under 24
Answer:
Fraction=1/5=0.2
Step-by-step explanation:
If the student is 4m away from the school bell and moves 20m away, it means that he is 5 times more distant from the school bell and therefore should listen 5 times less, that is, 1/5 of the original sound.
Note: this as long as the initial environment conditions of 4m are the same at 20m
Answer:
It opens to the right and the vertex is at (0, -8).
The axis of symmetry is y = -8.
Step-by-step explanation:
The vertex is halfway between the directrix and the focus.
The focus is to the right of the directrix so the curve will open towards the right. The axis of symmetry is the line y = -8.
