Answer:

5u - 4v = 51i + 3j

Step-by-step explanation:

The given vectors are u=7i + 3j and v=-4i + 3j, find 5u-4v in terms of unit vectors i and j.

We substitute the vectors to get:

5u - 4v = 5(7i + 3j) - 4( - 4i + 3j)

We perform the scalar multiplication to get:

5u - 4v = 35i + 15j  + 16i  - 12j

Group the components;

5u - 4v = 35i  + 16i   + 15j- 12j

We simplify to get:

5u - 4v = 51i   + 3j

Find g'​(t) for the function ​g(t) = 7/t^4
Alex17521 [72]

The differentiation of the function g(t) = 7/t⁴ will be equal to g¹(t)=-28/t⁵

<h3>What is differentiation?</h3>

The method of determining the derivative, or rate of change, of a function in mathematics.is termed as the differentiation.

Given that:-

g(t)= \dfrac{7}{t^4}

The derivative will be calculated as:-

g'(t)=7   \dfrac{d}{dt}(t^{-4})\\\\\\g'(t)=7\times (-4t^{-5})\\\\\\g'(t)=\dfrac{-28}{t^5}

Therefore the differentiation of the function g(t) = 7/t⁴ will be equal to g¹(t)=-28/t⁵

Given in the question an equation

tan(x) = 5

       x =  tan^{1}(5)

       x = 78.69

       x ≈ 78.7°

In radian:
