An object is acted upon by the forces F1=<10,6,4> and F2=<0,3,9>. Find the force F3 that must act on the object

murzikaleks [220]

$\vec F_3=\langle x,y,z\rangle$ is a force vector such that

$\vec F_1+\vec F_2+\vec F_3=\vec0$

$\implies\langle10,6,4\rangle+\langle0,3,9\rangle+\langle x,y,z\rangle=\langle0,0,0\rangle$

$\implies\begin{cases}10+x=0\\9+y=0\\13+z=0\end{cases}\implies x=-10,y=-9,z=-13$

So the missing force is

$\boxed{\vec F_3=\langle-10,-9,-13\rangle}$

When Raphael solved the system below by using the method of elimination, he changed the second equation to -8x-2y=-2 what proper

galben [10]

For this case, what we are going to do is use the following property:
Multiply an equation by a scalar.
In this case, the scalar will be:
k = -2
We have then that equation 2 will be:
k * (4x + y) = k * 1
-2 * (4x + y) = - 2 * 1
-8x-2y = -2
Answer:
The property that justifies this manipulation is:
Multiply an equation by a scalar.

Kwame borrowed 300 Ghana cedis from a finance company. He repaid the loan in six equal installment 55 Ghana cedis. How much inte

Bumek [7]

Answer:

The amount of interest, he payed is 30 Ghana Cedis

Step-by-step explanation:

The amount Kwame borrowed from the finance company, P = 300 Ghana Cedis

The amount he repaid in each installment, M = 55 Ghana Cedis

The number of installments with which he repaid the loan, n = 6 installments

The amount of interest, "i", he payed, is given by the following formula;

The amount of interest, he payed, i = M × n - P

Therefore, i = 55 × 6 - 300 = 30

The amount of interest, he payed = i = 30 Ghana Cedis.
