Answer:

Step-by-step explanation:

$3x+5y=100\\x+y=24\\$

The first thing you have to do is subtract equations.

$2x+4y=76\\x+2y=38\\$

We know that x+y=24.

Subtract that from the equation we got now.

$y=14$

There are 14 5 point questions and ten 3 point questions.

70+30=100

Find a unit vector in the same direction as the given vector: v = −14.5i + 2.5 j.

Elis [28]

ANSWER

$- \frac{29}{866} \sqrt{866} i + \frac{5}{866} \sqrt{866} j$

EXPLANATION

The given vector is v = −14.5i + 2.5 j.

The magnitude of this vector is

$|v| = \sqrt{ {( - 14.5)}^{2} + {2.5}^{2} }$

$v| = \sqrt{ {( - 14.5)}^{2} + {2.5}^{2} }$

$v| = \sqrt{ 216.5} = \frac{ \sqrt{866} }{2}$

The unit vector in the direction of this vector is

$= \frac{v}{ |v| }$

$= - \frac{14.5}{ \frac{ \sqrt{866} }{2} } i + \frac{2.5}{ \frac{ \sqrt{866} }{2} } j$

$= - \frac{29}{866} \sqrt{866} i + \frac{5}{866} \sqrt{866} j$

Find the 13th term of the geometric sequence 3, -15, 75, ...

Maksim231197 [3]

Step-by-step explanation:

$an = a1 + (n - 1)d \\ d = a2 - a1 \\ a1 = 3 \\ a2 = - 15 \\ d = - 15 - 3 = - 18$

$a13 = 3 + (12) \times ( - 18) \\ a13 = 3 - 216 \\ a13 = - 213$
