Answer:

y=3\sin(2x)

Step-by-step explanation:

To find the equation of a sinusoidal curve, you need to know the period and the amplitude. The amplitude can clearly be seen to be at 3, while the period is just \pi. Since there isn't any vertical or horizontal shift, the equation is simply:

y=3\sin(2x)

Hope this helps!

Answer:

V ≈ 8.67x10^7 ft^3

Step-by-step explanation:

We know that the volume of a pyramid is V= (lwh)/3

Since it is a square pyramid, it means that the length and the width are the same:

Length=755.9 feet

Width=755.9 feet

Height=455.4 feet

So, the volume is :

V = [(755.9)(755.9)(455.4)]/3

V = 86736214.158 ft^3

V ≈ 8.67x10^7 ft^3

Hope this helps!

In a group of 42 students, 9 study both Art and Biology.
LUCKY_DIMON [66]
Answer:
The probability the student studies Art and
Biology is 0.2143.
Step-by-step explanation:
Denote the events as follows:
A = a students studies Art
B= a students studies Biology
The information provided is:
N = 42
n (An B) = 9
n (A' n B) = 10
n (A' n B') =7
Then the number of students who study Art
but not Biology is:
n(An B') = N -n (An B) -n (A' nB) - n (A'n B')
= 42 - 10 - 7 - 9
= 16
The number of students who study Art but
not Biology is 16.
Compute the probability the student studies
Art and Biology as follows:
P(ANB)
n(ANB)
= 0.2143
Thus, the probability the student studies Art
and Biology is 0.2143.
