(Quadratic Formula) (Irrational level 1)

Leni [432]

Answer:

(-11 +/- sqrt 21) / 10

-0.64 , -1.56 to the nearest hundredth.

Step-by-step explanation:

9v^2 + 11v + 5 = 4v^2

5v^2 + 11v + 5 = 0

Using the quadratic formula:

v = [ - 11 +/- sqrt(11^2 - 4*5*5) ] / 2*5

= (-11 +/- sqrt 21) / 10

= -0.64 , -1.56 to the nearest hundredth.

What is the angle through which the pendulum oscillates between two maximum positions?

babymother [125]

Answer:

does this help

Step-by-step explanation:

What is the maximum angle of a pendulum?

Paul Appell pointed out a physical interpretation of the imaginary period: if θ0 is the maximum angle of one pendulum and 180° − θ0 is the maximum angle of another, then the real period of each is the magnitude of the imaginary period of the other.

A fitness center runs a contest for customers who enroll in its annual membership plan. The customers are allowed to draw a coup

Alchen [17]

There are 35 coupons in the jar.
The probability to choose coupon for 1 month of extended membership is $p(A)= \frac{20}{35} = \frac{4}{7}$ .
The probability to choose coupon for 1.5 months of extended membership is $p(B)= \frac{10}{35} = \frac{2}{7}$ .

Answer: With probability $\frac{4}{7}$ a customer will get 30 days extended membership, 
with probability $\frac{2}{7}$ a customer will get 450 days extended membership,
with probability $\frac{1}{7}$ a customer will get 60 days extended membership.
The probability to choose coupon for 1 month of extended membership is $p(C)= \frac{5}{35} = \frac{1}{7}$ .
Together P(A)+P(B)+p(C)=1.
