T=√k(k-b)(k-m).... make b the subject of the formula​
Liono4ka [1.6K]

Answer:

b = -T²/k(k-m)  + k

Step-by-step explanation:

Given the equation T =√k(k-b)(k-m), we are to make b the subject of the formula​

Square both sides

T² = (√k(k-b)(k-m))²

T² = k(k-b)(k-m)

T²/k(k-m) = k-b

Rearrange

k - b = T²/k(k-m)

b - k = - T²/k(k-m)

Add j=k to both sides

b - k + k = - T²/k(k-m)  + k

b = -T²/k(k-m)  + k

This gives the required expression

A single die is rolled. find the probability of rolling an eveneven number or a number less than 55.
sineoko [7]
The numbers less than 5 or even are {1, 2, 3, 4, 6}. This is 5 of the 6 possible numbers.

The probability of getting one of these on a single roll of a single die is 5/6.

Questions<br> E<br> Given EA = 8 and AT = 10<br> Find ET
xxTIMURxx [149]

Answer:

ET = 80/A^2

Step-by-step explanation:

First, isolate the variables that you need, which is E and T, using the two equations you were given.

EA = 8

E = 8/A (divide A on both sides to isolate E)

AT = 10

T = 10/A (divide A on both sides to isolate T)

Now, substitute.

ET --> (8/A) x (10/A) = 80/A^2
