A) 36 means that there are 36 students taking Italian and music AT SAME TIME
b) 59 means that there are 59 students taking only music
c) 48 means that there are 48 students taking neither Italian nor music
d) Italian OR Music = 97 + 36 +59 = 192
e) Do not take Italian: 48 + 59 = 107
A train leaves the station at time xequals
0.
Traveling at a constant speed, the train travels 328
km in 3.4
h. Round to the nearest 10 km and the nearest whole hour. Then represent the distance, y, the train travels in x hours using a table, an equation, and a graph. give brainliest x
Answer:
G(f(x)) = A. 3x + 7
Step-by-step explanation:
Plug F(x) into the x on G. so (3x+2) +5 = 3x+7
Height of the woman = 5 ft
Rate at which the woman is walking = 7.5 ft/sec
Let us assume the length of the shadow = s
Le us assume the <span>distance of the woman's feet from the base of the streetlight = x
</span>Then
s/5 = (s + x)/12
12s = 5s + 5x
7s = 5x
s = (5/7)x
Now let us differentiate with respect to t
ds/dt = (5/7)(dx/dt)
We already know that dx/dt = 7/2 ft/sec
Then
ds/dt = (5/7) * (7/2)
= (5/2)
= 2.5 ft/sec
From the above deduction, it can be easily concluded that the rate at which the tip of her shadow is moving is 2.5 ft/sec.
