Answer:

XW = 4 units

Step-by-step explanation:

Given tanf° = $\frac{2}{1}$ , then

tanf° = $\frac{opposite}{adjacent}$ = $\frac{YW}{XW}$ = $\frac{8}{XW}$ = $\frac{2}{1}$ ( cross- multiply )

2XW = 8 ( divide both sides by 2 )

XW = 4

I got 12 because each time you are dividing the number in half. Half of 24 is 12.

A sequence of 7 numbers starts with 8. The second number in the sequence is unknown and may be positive or negative. The third t

Answer:

4

Explanation:

$a_1=8,a_7=0$

Since the third term is the sum of the two previous terms

$a_3=a_2+a_1$

$a_7=a_6+a_5$

$a_7=a_5+a_4+a_4+a_3$

Continuing in like manner

$a_7=5a_3+3a_2$

Since $a_3=a_2+a_1$

$a_7=5(a_2+a_1+3a_2$

$a_7=5a_2+5a_1+3a_2$

$a_7=8a_2+5a_1$

Recall: $a_1=8,a_7=0$

$0=8a_2+5*8$

$8a_2=-40$

$a_2=-5$

The sequence is therefore:

8,-5,3,-2,1,-1,0

The sum of the seven numbers is 4.

Oxana [17]

Answer:

l = 15 and w = 25

Step-by-step explanation:

$l - w = - 10$

$l + w = 40$

Adding both equations

$2l = 30$

$l = 15$

subtracting both equation

$2w = 50$

$w = 25$

How to solve this system of equal: x+y+z=1;x^2+y^2+z^2=1

swat32

There are infinitely many solutions.

Algebraically, we can eliminate $z$ and try to solve for $x,y$ :

$x+y+z=1\implies z=1-x-y$

Then

$x^2+y^2+(1-x-y)^2=1$

$\implies x^2+y^2+1-2x+x^2-2y+y^2+2xy=1$

$\implies x^2-x+y^2-y+xy=0$

which is the equation of an ellipse.
