How much water can the water trough hold?
djverab [1.8K]

Answer: 200-300 liters

Step-by-step explanation: Each trough should be able to hold at least 200-300 litres of water with a minimum flow rates of 10 litres/minute. Trough volume can be reduced to about 100 litres if the flow rate is increased to 20 litres/minute. Likewise, how many gallons is a 2x2x4 tank?

) For what values of k does the function y = cos(kt) satisfy the differential equation 4y 00 = −25y? (1) (b) For those values of
nordsb [41]

Answer:

a.k=\pm\frac{5}{2}

Step-by-step explanation:

We are given that a solution

y= cos (kt) satisfied the differential equation

4y''=-25y

We have to find  the value of k

a.y=coskt

Differentiate w.r.t x

Then we get

y'=-k sinkt

\frac{d(cos ax)}{dx}=-asin ax

Again differentiate w.r.t x

y''=-k^2 cos kt (\frac{d(sinax)}{dx}=a cos ax

Substitute the value in given differential equation

-4 k^2 coskt=-25 coskt

coskt cancel on both sides then we get

4k^2=25

k^2=\frac{25}{4}

a.k=\sqrt{\frac{25}{4}}=\pm\frac{5}{2}

b.We have to show that y=A sin kt + B cos kt is a solution to given differential equation for k=\pm\frac{5}{2}

Substitute the values of k

Then we get

y=A cos \frac{5}{2} kt+ B sin \frac{5}{2} kt

Differentiate w.r.t x

y'=-\frac{5}{2} A sin \frac{5}{2}t+ \frac{5}{2} B cos \frac{5}{2}t

Again differentiate w.r.t x

Then we get

y''=-\frac{25}{4}A cos \frac{5}{2} t+\frac{25}{4} B sin\frac{5}{2} t

Substitute the value of y'' and y in given differential equation

-25 A cos \frac{5}{2} t +25 B sin \frac{5}{2} t=-25(A cos \frac{5}{2} t+ B sin \frac{5}{2} t)

-25 A cos \frac{5}{2} t +25 B sin \frac{5}{2} t=-25 y

LHS=RHS

Hence, every function of the form

y=A cos kt +B sin kt is a s solution of given differential equation for k=\pm\frac{5}{2}

Where A and B are constants

Given a family with three ​children, find the probability of the event. The oldest is a boy and the youngest is a girl​, given t
mafiozo [28]

Answer:

The possible cases of the children in increasing order of age are

1) Boy,Boy,Girl

2)Boy,Girl,Boy

3)Girl,Boy,Boy

4)Girl,Girl,Boy

5)Girl,Boy,Girl

6)Boy,Girl,Girl

The favorable cases in our event are 2 numbered 4 and 5

Thus the required probability is

P(E)=\frac{2}{6}\\\\P(E)=\frac{1}{3}

BRAINLIESTTTTTTTTT! Urgent help needed! Please find the measure of angle B!
Crank
Answer: 59 degrees

--------------------------------------------------------------
--------------------------------------------------------------

Work Shown:

We have the three angles:
angle A = (3x+2) degrees
angle B = (2x+7) degrees
angle C = 41 degrees

Rule: for any triangle, the three angles add up to 180 degrees

(angle A) + (angle B) + (angle C) = 180
(3x+2) + (2x+7) + (41) = 180
3x+2 + 2x+7 + 41 = 180
(3x+2x)+(2+7+41) = 180
(5x)+(50) = 180
5x+50 = 180
5x+50-50 = 180-50
5x = 130
5x/5 = 130/5
x = 26

Now use this x value to find the measure of angle B
angle B = (2x+7) degrees
angle B = (2*x+7) degrees
angle B = (2*26+7) degrees
angle B = (52+7) degrees
angle B = 59 degrees

Side Note: Angle A is 80 degrees (3x+2 = 3*26+2 = 78+2 = 80)

Another thing to note: A+B+C = 80+59+41 = 180
