Answer:

The price would be 55.25 in U.S dollars, you saved 29.75. $85 x .35=29.75.

Answer:

$55,25

Step-by-step explanation:

If 100% is $85

we have to discover the 35%. So:

100%________$85

35%_________ ?

35x85= 2975 then

2975/100= 29,75

29,75 is the %35 of $85.

Now we have to subtract the discount:

85-29,75= 55,25

Assume u4 is not a linear combination of {u1,u2,u3}

Feliz [49]

Answer:

A. {u1,u2,u3,u4} is a linearly independent set of vectors unless one of {u1,u2,u3} is the zero vector.

Step-by-step explanation:

Given that u4 is not a linear combination of {u1,u2,u3}

This means there is no possibility to write u4 = au1+bu2+cu3 for three scalars a,b,and c.

This gives that $u_4-au_1-bu_2-cu_3 \neq 0$

This implies that these four vectors are not linearly dependent but linearly independent.

Hence option a is right.

A. {u1,u2,u3,u4} is a linearly independent set of vectors unless one of {u1,u2,u3} is the zero vector.

Find an equation of the tangent line to the graph of

Allisa [31]

Answer:

$y- y_o = m(x-x_o)$

For this case m represent the slope and is given by $m= g'(4) = 2$ and from the other condition given we know that $x_o = 4, y_o =-3$ . And replacing we got:

$y -(-3) = 2 (x-4)$

And if we reorganize the terms we have:

$y+3 = 2x -8$

And subtracting 3 in both sides we got:

$y = 2x -11$

Step-by-step explanation:

For this case we have the following function y=g(x) and we want to find the tangent line to this function using the conditions: $g(4) =-3, g'(4)=2$

So we need a function like this one:

$y- y_o = m(x-x_o)$

For this case m represent the slope and is given by $m= g'(4) = 2$ and from the other condition given we know that $x_o = 4, y_o =-3$ . And replacing we got:

$y -(-3)=2(x-4)$
