Pick 2 sets of points from ur table...

(-4,-16)(-2,-6)
slope = (y2 - y1) / (x2 - x1)
slope = (-6 - (-16) / (-2 - (-4) = (-6 + 16) / (-2 + 4) = 10/2 = 5

u could pick any 2 of ur sets of points.....it will come out the same...let me show you...
(2,14)(4,24)
slope = (y2 - y1) / (x2 - x1)
slope = (24 - 14) / (4 - 2) = 10/2 = 5...see, it is the same no matter what 2 sets of points u choose)

I need the domain to this.

aliina [53]

Answer:

all real numbers greater than zero

Step-by-step explanation:

The square root of a number must be greater than or equal to zero

sqrt(x) ≥0

Squaring each side

x ≥0

This means the domain is all real numbers greater than or equal to zero

I would go with all real numbers greater than zero since it is the closest answer

Identify the 12th term of a geometric sequence where a1 = 8 and a6 = −8,192.

vodka [1.7K]

Geometric sequence
$a_{n}=a_{1}*r^{n-1}$
r=common ratio
a1=first term
find r

a1=8
a6=-8192
$-8192=a_{6}=8*r^{6-1}$
$-8192=8*r^{5}$
divide both sides by 8
$-1024=8*r^{5}$
take 5th root of both sides
-4=r
sub
$a_{12}=8*(-4)^{12-1}$
$a_{12}=8*(-4)^{11}$
$a_{12}=8*-4194304$
$a_{12}=-33554432$

Calculate the value <br><br>X + 20<br>3x + 10<br>5x +10°

Serga [27]

Answer:

x + 20° = 35.56°

3x + 10° = 56.68°

5x + 10° = 87.8°

Step-by-step explanation:

Assume;

Given measures are angle of a triangle

x + 20°

3x + 10°

5x + 10°

Find:

Value of each angle

Computation:

We know that, sum of all interior angle in a triangle is 180°

So,

We say that

x + 20° + 3x + 10° + 5x + 10° = 180°

9x + 40° = 180°

9x = 140°

x = 15.56°

So,

x + 20° = 15.56 + 20 = 35.56°

3x + 10° = 3(15.56) + 10 = 56.68°

5x + 10° = 5(15.56) + 10 = 87.8°
