If you're solving for x, you'd move all the terms containing x to the left side of the equation:
d^2y/dx^2+4y/x-12y-cos^2(x)+sin^2(x)=0
If you're solving for y, you'd simplify both sides of the equation, then isolating the variable:
y=xcos(2x)
Answer:
784 in² of wood
Step-by-step explanation:
Sarah needs two supports by shelf, and she will build 4 shelves
then she will need 8 supports
Now each support is a right isosceles triangle.
Area of a triangle is
A(t) = 1/2 *b*h where b is the base and h is the heigh of the triangle.
A right isosceles triangle has two sides ( base and heigh equals) and in our particular case are equals to 14 in, therefore
A(t) = 1/2*14*14
A(t) = 98 in²
Sarah needs 8 pieces of 98 in² she needs
A = 8*98
A = 784 in² of wood
Answer:
w = 1
Step-by-step explanation:
If the slope is 0, then this line will be horizontal.
This means that the y value will be the same for all points on the line.
Since we are given the point (3, 1), we know that the y value is 1. This means all other points on the line will have 1 as the y value.
So, w is equal to 1 because it is the y value in that ordered pair.
