squaerroot 2 sin(p+57.28996163)
Let's find x. This will allow us to find the value of the second expression.
x - 3 = 1
x = 4
Now, we can simply plug this x-value into the second expression to obtain 4^2 - 3(4) - 1 = 3.
Thus, our answer is 3.
You can think of it as two separate fractions. 1/2 divided by 3/1. You can solve this by multiplying the first fraction by the reciprocal of the second fraction. A reciprocal is switching the fraction by turning it over. So you just have to solve 1/2 multiplied by 1/3. As a result you get 1/6 as the answer! Hope this helped!
Dr/dt= 8cmM-¹
dA/dt = ?
but A= πr²
so dA/dr =2πr
but recall
dA/dt = dA/dr • dr/dt
dA/dt = 2πr • 8cmM-¹
dA/dt = 2×π×39 ×8 = 624cm²M-1
