Answer:
3.9984i-3.0021j
Step-by-step explanation:
Due to the fact that we are only asked for the components on A, we will focus on that information.
The first thing we need to do is to dimension the magnitud of A as a hypotenuse of a right triangle. As the vector is ponting in south-east direction, we can asume that it´s (i) component will be positive and it´s (j) component will be negative.
Now, using trigonometric functions we can find the components of the vector A by multiplying the magnitude by -sin(x) for (j) and cos(x) for (i).
-5sin(36.9)=-3.0021
(this component is negative due to the fact that the vector is pointing down)
5cos(36.9)= 3.9984
Now we write in the correct notation x(i) + y(j)
3.9984i-3.0021j
V of a cone= 1/2
V=1/2*pi*r^2*h = .5*pi*(9)*(10) = 141.4m^3

Answer:
Rounded to the nearest tenth the solutions to the equation are:
x = -1.7 and x = -6.3
Step-by-step explanation:
Since this is a quadratic equation of the form:
Use the quadratic formula, which tells you that the solutions would be given by:
So in our case, the quadratic formula gives:
which gives us two real solutions:
x = - 1.654792
x = -6.345207
Which rounded to the nearest tenth give:
x = -1.7 and x = -6.3
